Two members of the Scattered Spider cybercrime group received jail sentences in the UK for the 2024 cyberattack on Transport for London.

A UK court sentenced two Scattered Spider members, Thalha Jubair (20) and Owen Flowers (18), for their role in the 2024 cyberattack on Transport for London (TfL). Transport for London (TfL) is a local government body responsible for most of the transport network in London, United Kingdom.

The attack disrupted transport services, including Dial-a-Ride for vulnerable passengers, concessionary travel cards, digital payments, and the rollout of contactless ticketing. The attack also exposed customer data from the Oyster refunds system and delayed customer refunds and travel card applications.

All 27,000 employees had to reset their passwords, while 148 systems went offline, forcing staff to rely on manual processes.

The incident cost TfL an estimated £29 million ($39 million); however, the NCA reported that a complete shutdown could have caused up to £56 billion in economic damage.

The case marks another law enforcement success against one of the most active cybercrime groups targeting major organizations.

TfL estimates the attack cost £29 million, while a complete shutdown could have caused up to £56 billion in economic damage.

In September 2025, the National Crime Agency (NCA) arrested the two teenagers at their home addresses.

The law enforcement first arrested Flowers for the TfL attack, and investigators found evidence linking him to intrusions against U.S. healthcare providers SSM Health Care Corporation and Sutter Health. Authorities seized laptops, hard drives and USB devices, including one containing a screenshot of TfL network access.

Investigators also found videos showing Jubair accessing TfL systems during the attack while the two exchanged messages on Telegram and collaborated through an online workspace. Flowers was later arrested for breaching bail conditions, while Jubair faced additional charges for refusing to provide device passwords.

Both were charged with conspiring together to commit unauthorised acts against TfL, under the Computer Misuse Act.

“They both pleaded guilty to the attack last month in what was only the second criminal prosecution of its kind in the UK under the Computer Misuse Act (CMA).” reads the press release published by the NCA. “Section 3ZA of the CMA is the most serious section as it applies where the unauthorised act causes or creates a significant risk of serious damage, and the person intends or is reckless as to that damage.”

They were each sentenced to five years and six months in prison in what UK authorities described as the country’s largest cybercrime prosecution to date.

Although hackers continued using the Scattered Spider name into early 2026, UK authorities say the arrests of Jubair and Flowers effectively dismantled the group’s core operations. Microsoft also assessed that the arrests significantly reduced the group’s ability to carry out cyberattacks.

“Although other cybercriminals may continue to use the damaged Scattered Spider brand, the NCA’s action against Jubair and Flowers effectively halted the group’s criminal activity.” states NCA. “Independent assessment supports this, with Microsoft confirming that the arrests materially degraded the group’s ability to continue conducting cybercriminal operations.”

In July, Peter Stokes, 19, an alleged Scattered Spider member known online as “Bouquet,” was extradited from Finland to the U.S. to face hacking, fraud, and extortion charges. Prosecutors say he took part in multiple cyberattacks, including a 2025 breach of a luxury jewelry retailer where attackers allegedly stole data and demanded about $8 million in cryptocurrency.

“Among other offenses, the complaint alleges that Stokes and other co-conspirators breached a luxury jewelry retailer’s computer system, exfiltrated data from the company, and made a ransom demand of approximately $8 million in cryptocurrency in May 2025.” reads the press release published by DoJ. “The retailer’s security personnel successfully evicted the threat actors from the company’s computer network and no ransom was paid. The retailer nonetheless suffered a loss of at least $2 million due to business disruption, investigation, and mitigation of the threat.”

He was arrested in Finland in April on an Interpol Red Notice.

U.S. officials said Scattered Spider (aka Octo Tempest, UNC3944, and 0ktapus) has caused major disruption by targeting American companies, stealing data, encrypting systems, and demanding cryptocurrency payments. The FBI warned that the group has cost businesses millions of dollars and disrupted critical operations. Authorities pledged to continue working with international partners to identify, disrupt, and prosecute members of the group, regardless of where they operate.

The cybercrime group is suspected of hacking into hundreds of organizations over the past two years, including Twilio, LastPass, DoorDash, and Mailchimp.

Scattered Spider members are part of a broader cybercriminal community called “The Com,” where hackers brag about high-profile cyber thefts, typically initiated through social engineering tactics like phone, email, or SMS scams to gain access to corporate networks.

In April 2026, Tyler Buchanan, a 24-year-old from Scotland, also linked to the Scattered Spider group, admitted in a US court that he hacked dozens of companies, committed fraud, and stole millions in cryptocurrency. Spanish police arrested the British national in Palma de Mallorca while attempting to fly to Italy. During the arrest, police confiscated a laptop and a mobile phone. The arrest resulted from a joint operation conducted by the U.S. Federal Bureau of Investigation (FBI) and the Spanish Police.

In April 2025, Noah Urban, 20, linked to Scattered Spider (UNC3944), pleaded guilty in Florida and California to conspiracy, wire fraud, and identity theft. He admitted involvement in phishing and fraud operations, including stealing at least $800,000 in crypto from victims between Aug 2022 and Mar 2023. He also helped export stolen data and run multi-state cybercrime activities tied to the group.

In November 2025, two British teenagers, Thalha Jubair (19) and Owen Flowers (18), accused of links to Scattered Spider, pleaded not guilty in Southwark Crown Court to charges under the Computer Misuse Act. They are alleged to have conspired in a cyberattack against Transport for London (TfL) in 2024. Both were arrested in September by the NCA and formally denied the accusations in court.

Scattered Spider members are part of a broader cybercriminal community called “The Com,” where hackers brag about high-profile cyber thefts, typically initiated through social engineering tactics like phone, email, or SMS scams to gain access to corporate networks.

“The criminal complaint charges Peter Stokes with membership in Scattered Spider, a hacking group that has been involved in over 100 network intrusions, resulting in more than $100 million in ransom payments and millions more in damages to the victims,” said Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division. “The charges unsealed today are the result of years of work by the Criminal Division, the U.S. Attorney’s Office for the Northern District of Illinois, and the FBI. We will continue to partner to ensure that cybercriminals cannot evade the reach of the United States.”

The case is part of the FBI’s Operation Riptide, a long-term effort to disrupt cybercriminals, their infrastructure, and financial networks. Americans reported more than $20 billion in cybercrime losses last year, up 26% from the previous year.

In April 2026, Tyler Buchanan, a 24-year-old from Scotland, also linked to the Scattered Spider group, admitted in a US court that he hacked dozens of companies, committed fraud, and stole millions in cryptocurrency.

An alleged member of the Scattered Spider cybercrime group has been extradited from Finland to the United States to face federal charges related to conspiracy, cyber intrusion, and fraud. U.S. authorities said the case marks another step in their ongoing efforts to prosecute individuals accused of participating in high-profile cybercrime operations linked to the notorious hacking group.

Peter Stokes, 19, a dual U.S. and Estonian citizen, made his initial appearance in federal court in Chicago after being extradited from Finland.

According to the U.S. Department of Justice, Stokes was arrested by Finnish authorities in April following an Interpol Red Notice and was transferred to the United States last week. A criminal complaint filed in the Northern District of Illinois accuses him of participating in cyberattacks carried out as part of the Scattered Spider group.

Scattered Spider Linked to More Than 100 Network Intrusions

According to the complaint, Scattered Spider, also known as Octo Tempest, UNC3944, and 0ktapus, has been associated with more than 100 network intrusions. Authorities allege the group's activities have resulted in over $100 million in ransom payments and millions of dollars in additional damages suffered by victims.

Investigators said the group targeted companies across the United States by obtaining access to employee accounts through fraudulent methods.

Once inside corporate networks, the attackers allegedly encrypted data or exfiltrated sensitive information to remote servers before demanding cryptocurrency payments to restore access or prevent the public release of stolen data.

Complaint Details Alleged Luxury Retailer Cyberattack

The criminal complaint describes an alleged cyber intrusion that occurred in May 2025 involving a luxury jewelry retailer.

Federal prosecutors allege that Stokes and other co-conspirators breached the retailer's computer systems, exfiltrated company data, and demanded approximately $8 million in cryptocurrency as ransom. According to court documents, the retailer's security team successfully removed the threat actors from its network before any ransom payment was made.

Although the company did not pay the ransom, authorities said it still incurred losses of at least $2 million due to business disruption, investigation costs, and mitigation efforts following the incident.

Operation Riptide Targets Cybercrime Networks

The extradition and criminal charges were announced by the Department of Justice, the U.S. Attorney's Office for the Northern District of Illinois, and the FBI. The investigation also involved the FBI's Copenhagen Law Enforcement Attaché Office, the FBI Las Vegas Field Office, the Justice Department's Office of International Affairs, and Finland's National Bureau of Investigation.

Officials said the case forms part of Operation Riptide, an ongoing FBI campaign focused on disrupting cybercriminal actors, infrastructure, financial networks, and fraud schemes targeting Americans.

According to the FBI, Americans reported more than $20 billion in cybercrime losses last year, representing a 26% increase compared with the previous year.

Authorities Cite International Cooperation

Assistant Attorney General A. Tysen Duva said the charges stem from years of investigative work by the Justice Department, the U.S. Attorney's Office, and the FBI, adding that authorities would continue working together to pursue cybercriminals operating across international borders.

U.S. Attorney Andrew S. Boutros said the alleged attacks caused significant disruption to businesses across the United States and emphasized the government's commitment to prosecuting individuals involved in cyber intrusions.

FBI Special Agent-in-Charge Douglas S. DePodesta also highlighted the role of international law enforcement partnerships in identifying alleged members of the hacking group and pursuing cross-border cybercrime investigations.

Recent Guidance on Scattered Spider Threat

The arrest follows recent law enforcement efforts targeting the Scattered Spider threat group. In July 2025, the FBI and CISA released updated guidance describing the group's latest attack techniques, including the use of DragonForce ransomware to encrypt VMware ESXi servers.

The advisory urged organizations to maintain isolated offline backups, implement phishing-resistant multifactor authentication (MFA), and apply application controls to manage software execution.

Separately, in November 2025, two alleged Scattered Spider members appeared before Southwark Crown Court in the United Kingdom and pleaded not guilty to charges related to the August 2024 cyberattack on Transport for London (TfL).

The Department of Justice emphasized that the complaint against Stokes contains allegations only. As with all criminal cases, he is presumed innocent unless and until proven guilty in court.

Two alleged members of the cybercrime collective Scattered Spider have pleaded guilty to their roles in the Transport for London cyberattack, an incident that disrupted services, exposed customer data, and resulted in approximately £29 million in losses and recovery costs for London's transport authority. The guilty pleas were entered by Thalha Jubair, 20, from East London, and Owen Flowers, 18, from Walsall, West Midlands, on the opening day of proceedings at Woolwich Crown Court. The pair had been due to stand trial on June 22 but changed their pleas to guilty.

Transport for London Cyberattack Led to Major Disruption

According to the National Crime Agency (NCA) and City of London Police, TfL's network was infiltrated between August 31 and September 3, 2024. The breach forced all 28,000 employees to attend TfL offices for password resets and caused significant operational disruption across the organization. The TfL cyberattack also resulted in unauthorized access to data held within TfL's Oyster refunds system. The incident affected the authority's customer refund process, delaying reimbursements for some customers. In addition, the application system for Oyster photocards used by children and young people was temporarily shut down. Authorities said the attack caused substantial financial damage, with TfL reporting losses and recovery costs totaling approximately £29 million.

Investigation Linked Attackers to Scattered Spider

Jubair and Flowers were arrested at their homes on September 16, 2024, following a joint investigation conducted by the NCA and City of London Police. Investigators identified both individuals as members of Scattered Spider, a cybercriminal collective that has been linked to a number of high-profile intrusions. During searches of Flowers' residence, officers recovered laptops, desktop computers, hard drives, and USB storage devices. Evidence recovered from one Acer laptop included a screenshot showing connectivity to TfL infrastructure. [caption id="attachment_112868" align="aligncenter" width="600"] Source: NCA[/caption] Authorities also found evidence indicating Flowers had accessed an online marketplace that sold breached credentials. Investigators further discovered videos recorded by Flowers that allegedly showed Jubair accessing TfL systems during the attack. The investigation revealed that the two communicated through Telegram and collaborated using an online workspace platform that allowed multiple participants to work remotely on shared systems.

Additional Allegations Involving US Healthcare Networks

The investigation extended beyond the Transport for London cyberattack. When Flowers was first arrested on September 6, 2024, NCA officers identified evidence suggesting unauthorized activity targeting the networks of SSM Health Care Corporation and Sutter Health in the United States. Court records show Flowers pleaded guilty to charges related to a conspiracy to conduct unauthorized acts against SSM Health Care Corporation's computer systems with intent to impair operations. He also admitted attempting unauthorized acts against Sutter Health's systems with the same intent. Jubair additionally faced a charge for failing to disclose PINs or passwords associated with devices seized during the investigation. Authorities noted that Flowers breached bail conditions on two occasions in March and May 2025.

Law Enforcement Highlights Impact of Cybercrime

Paul Foster, Deputy Director and head of the NCA's National Cyber Crime Unit, described the case as a lengthy and highly complex investigation. He said the attack demonstrated that cybercrime has significant real-world consequences, affecting public services and causing millions of pounds in losses to critical national infrastructure. Foster also highlighted the growing threat posed by cybercriminal groups operating from the UK and other English-speaking countries, citing Scattered Spider as a notable example. Deputy Commissioner Nik Adams of the City of London Police said the cyberattack had a significant impact on essential public services and daily operations. He emphasized that individuals responsible for targeting critical organizations and causing financial harm would be pursued through coordinated law enforcement efforts. The investigation received support from the West Midlands Regional Organised Crime Unit and British Transport Police. Jubair and Flowers are scheduled to be sentenced at Woolwich Crown Court on July 16.

Two men pleaded guilty in the United Kingdom this week to criminal charges stemming from an August 2024 cyberattack that crippled Transport for London, the entity responsible for the public transport network in the Greater London area. The duo were key members of a prolific cybercrime group known as Scattered Spider, and their guilty pleas came on the first day of what was expected to be a six-week trial.

Thalha Jubair, 20, of East London and 18-year-old Owen Flowers of Walsall admitted conspiring to commit unauthorized acts against Transport for London computer systems and causing risk of serious damage to human welfare. According to a report from the BBC, Flowers alone admitted to being part of a conspiracy to hack into U.S. based healthcare providers SSM Health Care Corporation and Sutter Health in September 2024.

Jubair is also wanted by U.S. law enforcement agencies. In September 2025, prosecutors in New Jersey unsealed an indictment alleging Jubair and other Scattered Spider members committed computer fraud, wire fraud, and money laundering in relation to 120 computer network intrusions involving 47 U.S. entities between May 2022 and September 2025, and that the group’s victims paid at least $115 million in ransom payments.

In July 2025, KrebsOnSecurity reported that Flowers and Jubair were arrested in the United Kingdom in connection with Scattered Spider ransom attacks against the retailers Marks & Spencer and Harrods, and the British food retailer Co-op Group. Multiple sources familiar with those investigations said Flowers was the Scattered Spider member who anonymously gave interviews to the media in the days after the group’s September 2023 ransomware attacks disrupted operations at Las Vegas casinos operated by MGM Resorts and Caesars Entertainment.

According to prosecutors, Jubair co-ran a bustling Telegram channel called Star Chat, the home of a SIM-swapping group that used voice- and SMS-based phishing attacks to steal credentials from employees at the major wireless providers in the U.S. and U.K. The group would then use that access to sell a service that could redirect a target’s phone number to a device the attackers controlled and intercept the victim’s calls and text messages (including one-time codes for multi-factor authentication).

New Jersey prosecutors also allege Jubair also was involved in a mass SMS phishing campaign during the summer of 2022 that stole single sign-on credentials from employees at hundreds of companies. That weeks-long SMS phishing campaign led to intrusions and data thefts at more than 130 organizations, including LastPass, DoorDash, Mailchimp, Plex and Signal.

KrebsOnSecurity reported last year that one of Jubair’s alter egos at age 15 was “Everlynn,” a hacker who sold fraudulent “emergency data requests” that used compromised police and government email addresses to demand subscriber data (e.g. username, IP/email address) from major tech companies, claiming the requests concerned urgent matters of life and death and could not wait for a court order.

In April 2026, 24-year-old British national and Scattered Spider member Tyler “Tylerb” Buchanan pleaded guilty to wire fraud conspiracy and aggravated identity theft for participating in the group’s SMS phishing spree in the summer of 2022. The government said Buchanan, Jubair and others used the credentials harvested in that phishing campaign to steal at least $8 million in cryptocurrency from victims throughout the United States. Buchanan is currently scheduled to be sentenced on October 2.

In August 2025, 20-year-old Scattered Spider member from Florida named Noah Michael Urban was sentenced to 10 years in federal prison and ordered to pay $13 million in restitution, after pleading guilty to charges of wire fraud and conspiracy.

The U.S. Department of Justice says three alleged Scattered Spider defendants indicted along with Buchanan still face charges, including Ahmed Hossam Eldin Elbadawy, 24, a.k.a. “AD,” of College Station, Texas; Evans Onyeaka Osiebo, 21, of Dallas, Texas; and Joel Martin Evans, 26, a.k.a. “joeleoli,” of Jacksonville, North Carolina.

Flowers and Jubair are slated to be sentenced in a London court on July 15, 2026.

Here's a tip for you all. Unless you want to draw attention to yourself as a cybercriminal, don't flaunt your diamond-encrusted "HACK THE PLANET" necklace on Snapchat, or pose as a Sopranos crime boss while the FBI is reportedly closing in. Read more in my article on the Hot for Security blog.

US-Estonian suspect Peter Stokes arrested in Finland over alleged ties to Scattered Spider, facing US charges for cyberattacks, fraud, and data breaches.

A 24-year-old British national and senior member of the cybercrime group “Scattered Spider” has pleaded guilty to wire fraud conspiracy and aggravated identity theft. Tyler Robert Buchanan admitted his role in a series of text-message phishing attacks in the summer of 2022 that allowed the group to hack into at least a dozen major technology companies and steal tens of millions of dollars worth of cryptocurrency from investors.

Buchanan’s hacker handle “Tylerb” once graced a leaderboard in the English-language criminal hacking scene that tracked the most accomplished cyber thieves. Now in U.S. custody and awaiting sentencing, the Dundee, Scotland native is facing the possibility of more than 20 years in prison.

Scattered Spider is the name given to a prolific English-speaking cybercrime group known for using social engineering tactics to break into companies and steal data for ransom, often impersonating employees or contractors to deceive IT help desks into granting access.

As part of his guilty plea, Buchanan admitted conspiring with other Scattered Spider members to launch tens of thousands of SMS-based phishing attacks in 2022 that led to intrusions at a number of technology companies, including Twilio, LastPass, DoorDash, and Mailchimp.

The group then used data stolen in those breaches to carry out SIM-swapping attacks that siphoned funds from individual cryptocurrency investors. In an unauthorized SIM-swap, crooks transfer the target’s phone number to a device they control and intercept any text messages or phone calls to the victim’s device — such as one-time passcodes for authentication and password reset links sent via SMS. The U.S. Justice Department said Buchanan admitted to stealing at least $8 million in virtual currency from individual victims throughout the United States.

FBI investigators tied Buchanan to the 2022 SMS phishing attacks after discovering the same username and email address was used to register numerous phishing domains seen in the campaign. The domain registrar NameCheap found that less than a month before the phishing spree, the account that registered those domains logged in from an Internet address in the U.K. FBI investigators said the Scottish police told them the address was leased to Buchanan throughout 2022.

As first reported by KrebsOnSecurity, Buchanan fled the United Kingdom in February 2023, after a rival cybercrime gang hired thugs to invade his home, assault his mother, and threaten to burn him with a blowtorch unless he gave up the keys to his cryptocurrency wallet. That same year, U.K. investigators found a device at Buchanan’s Scotland residence that included data stolen from SMS phishing victims and seed phrases from cryptocurrency theft victims.

Buchanan was arrested by Spanish authorities in June 2024 while trying to board a flight to Italy. He was extradited to the United States and has remained in U.S. federal custody since April 2025.

Buchanan is the second known Scattered Spider member to plead guilty. Noah Michael Urban, 21, of Palm Coast, Fla., was sentenced to 10 years in federal prison last year and ordered to pay $13 million in restitution. Three other alleged co-conspirators — Ahmed Hossam Eldin Elbadawy, 24, a.k.a. “AD,” of College Station, Texas; Evans Onyeaka Osiebo, 21, of Dallas, Texas; and Joel Martin Evans, 26, a.k.a. “joeleoli,” of Jacksonville, North Carolina – still face criminal charges.

Two other alleged Scattered Spider members will soon be tried in the United Kingdom. Owen Flowers, 18, and Thalha Jubair, 20, are facing charges related to the hacking and extortion of several large U.K. retailers, the London transit system, and healthcare providers in the United States. Both have pleaded not guilty, and their trial is slated to begin in June.

Investigators say the Scattered Spider suspects are part of a sprawling cybercriminal community online known as “The Com,” wherein hackers from different cliques boast publicly on Telegram and Discord about high-profile cyber thefts that almost invariably begin with social engineering — tricking people over the phone, email or SMS into giving away credentials that allow remote access to corporate internal networks.

One of the more popular SIM-swapping channels on Telegram has long maintained a leaderboard of the most rapacious SIM-swappers, indexed by their supposed conquests in stealing cryptocurrency. That leaderboard previously listed Buchanan’s hacker alias Tylerb at #65 (out of 100 hackers), with Urban’s moniker “Sosa” coming in at #24.

Buchanan’s sentencing hearing is scheduled for August 21, 2026. According to the Justice Department, he faces a statutory maximum sentence of 22 years in federal prison. However, any sentence the judge hands down in this case may be significantly tempered by a number of mitigating factors in the U.S. Sentencing Guidelines, including the defendant’s age, criminal history, time already served in U.S. custody, and the degree to which they cooperated with federal authorities.

Tyler Robert Buchanan, a 24-year-old British hacker linked to Scattered Spider, admits to a multi-year US hacking scheme involving at least $8M in crypto theft.

A expansão internacional do grupo de cibercriminosos conhecido como Scattered Spider acendeu um sinal de alerta entre empresas latino-americanas. Especialistas em segurança apontam que, embora não haja registros confirmados de ataques desse grupo no Brasil ou vizinhos até o momento, seu alcance global e métodos sofisticados representam um risco iminente para organizações na região.

Com táticas de engenharia social elaboradas e capacidade de driblar defesas tradicionais, o Scattered Spider tem mirado grandes empresas em diversos países. “A questão não é mais ‘se’ seremos atacados, mas de ‘quando’ e ‘como’, afirma Felipe Guimarães, Chief Information Security Officer da Solo Iron. “As táticas empregadas pelo grupo exploram fragilidades universais, presentes em empresas em todo o mundo – o que inclui as empresas latino-americanas”, pondera o especialista.

Um dos maiores riscos é que os setores visados pelo Scattered Spider no exterior também são pilares econômicos na América Latina. O grupo historicamente focou suas ações em empresas de telecomunicações, terceirização de processos de negócios (BPO) e grandes empresas de tecnologia – indústrias que possuem ampla presença na região. Nos últimos tempos, foi observado um aumento de interesse do grupo pelo setor financeiro global, o que inclui bancos e instituições presentes no Brasil e países vizinhos.

“Isso significa que companhias latino-americanas, seja diretamente ou através de filiais e parceiras, podem entrar na mira à medida que o Scattered Spider amplia seu raio de atuação. Mesmo empresas que não operam internacionalmente devem se precaver, pois os criminosos podem enxergar organizações locais como pontes de entrada para fornecedores ou clientes globais, ou simplesmente como alvos lucrativos por si sós, caso identifiquem falhas de segurança exploráveis”, pontua Guimarães.

Na mira das agências de inteligência

Relatórios do FBI e da Agência de Segurança Cibernética e de Infraestrutura (CISA) dos EUA descrevem o Scattered Spider como “especialista em engenharia social”, empregando diversas técnicas para roubar credenciais e burlar autenticações.

Entre os métodos documentados estão phishing por e-mail e SMS (smishing), ataques de vishing (ligações telefônicas fraudulentas) em que os criminosos se passam por equipe de TI da própria empresa, e até esquemas elaborados de SIM swap – quando convencem operadoras de telefonia a transferir o número de celular de uma vítima para um chip sob controle deles. Essas táticas permitem interceptar códigos de autenticação multifator (MFA) enviados via SMS ou aplicativos, dando aos invasores as chaves para acessar sistemas internos.

Alguns incidentes recentes no cenário latino-americano já envolveram vetores parecidos, como uso de ferramentas legítimas em ataques e exploração de credenciais vazadas, o que reforça a necessidade de vigilância. Em 2024, por exemplo, houve casos de gangues de ransomware operando na região que abusaram de softwares legítimos e brechas em procedimentos internos de empresas, aplicando práticas muito similares ao do Scattered Spider.

Estratégias de mitigação

Diante da crescente ameaça representada por grupos como o Scattered Spider, Guimarães recomenda a adoção de estratégias com foco especial em fortalecer métodos avançados de autenticação multifator (MFA), preferencialmente resistentes a phishing, como chaves físicas de segurança ou soluções baseadas em certificados digitais. Técnicas como MFA com validação numérica e a restrição do uso de SMS para autenticação são essenciais para reduzir o risco de engenharia social e ataques por fadiga de notificações, muito usados pelo grupo.

Além disso, a adoção de uma abordagem mais robusta em relação à gestão de identidades e acessos (IAM) é uma estratégia muito importante na contenção desse tipo de ameaça. “As identidades digitais estão se tornando uma nova superfície de ataque; por isso, é fundamental que as empresas implementem políticas rígidas de gestão de identidades, controle granular de acessos e monitoramento contínuo das atividades dos usuários”, destaca.

“Também é muito importante o controle rigoroso sobre ferramentas de acesso remoto e a implantação de monitoramento avançado. É recomendável que as organizações restrinjam o uso dessas ferramentas por meio de listas autorizadas e adotem sistemas robustos como EDR e DLP para identificar rapidamente atividades suspeitas”, finaliza o especialista.

A prolific cybercriminal group that calls itself “Scattered LAPSUS$ Hunters” has dominated headlines this year by regularly stealing data from and publicly mass extorting dozens of major corporations. But the tables seem to have turned somewhat for “Rey,” the moniker chosen by the technical operator and public face of the hacker group: Earlier this week, Rey confirmed his real life identity and agreed to an interview after KrebsOnSecurity tracked him down and contacted his father.

Scattered LAPSUS$ Hunters (SLSH) is thought to be an amalgamation of three hacking groups — Scattered Spider, LAPSUS$ and ShinyHunters. Members of these gangs hail from many of the same chat channels on the Com, a mostly English-language cybercriminal community that operates across an ocean of Telegram and Discord servers.

In May 2025, SLSH members launched a social engineering campaign that used voice phishing to trick targets into connecting a malicious app to their organization’s Salesforce portal. The group later launched a data leak portal that threatened to publish the internal data of three dozen companies that allegedly had Salesforce data stolen, including Toyota, FedEx, Disney/Hulu, and UPS.

Last week, the SLSH Telegram channel featured an offer to recruit and reward “insiders,” employees at large companies who agree to share internal access to their employer’s network for a share of whatever ransom payment is ultimately paid by the victim company.

SLSH has solicited insider access previously, but their latest call for disgruntled employees started making the rounds on social media at the same time news broke that the cybersecurity firm Crowdstrike had fired an employee for allegedly sharing screenshots of internal systems with the hacker group (Crowdstrike said their systems were never compromised and that it has turned the matter over to law enforcement agencies).

Members of SLSH have traditionally used other ransomware gangs’ encryptors in attacks, including malware from ransomware affiliate programs like ALPHV/BlackCat, Qilin, RansomHub, and DragonForce. But last week, SLSH announced on its Telegram channel the release of their own ransomware-as-a-service operation called ShinySp1d3r.

The individual responsible for releasing the ShinySp1d3r ransomware offering is a core SLSH member who goes by the handle “Rey” and who is currently one of just three administrators of the SLSH Telegram channel. Previously, Rey was an administrator of the data leak website for Hellcat, a ransomware group that surfaced in late 2024 and was involved in attacks on companies including Schneider Electric, Telefonica, and Orange Romania.

Also in 2024, Rey would take over as administrator of the most recent incarnation of BreachForums, an English-language cybercrime forum whose domain names have been seized on multiple occasions by the FBI and/or by international authorities. In April 2025, Rey posted on Twitter/X about another FBI seizure of BreachForums.

On October 5, 2025, the FBI announced it had once again seized the domains associated with BreachForums, which it described as a major criminal marketplace used by ShinyHunters and others to traffic in stolen data and facilitate extortion.

“This takedown removes access to a key hub used by these actors to monetize intrusions, recruit collaborators, and target victims across multiple sectors,” the FBI said.

Incredibly, Rey would make a series of critical operational security mistakes last year that provided multiple avenues to ascertain and confirm his real-life identity and location. Read on to learn how it all unraveled for Rey.

WHO IS REY?

According to the cyber intelligence firm Intel 471, Rey was an active user on various BreachForums reincarnations over the past two years, authoring more than 200 posts between February 2024 and July 2025. Intel 471 says Rey previously used the handle “Hikki-Chan” on BreachForums, where their first post shared data allegedly stolen from the U.S. Centers for Disease Control and Prevention (CDC).

In that February 2024 post about the CDC, Hikki-Chan says they could be reached at the Telegram username @wristmug. In May 2024, @wristmug posted in a Telegram group chat called “Pantifan” a copy of an extortion email they said they received that included their email address and password.

The message that @wristmug cut and pasted appears to have been part of an automated email scam that claims it was sent by a hacker who has compromised your computer and used your webcam to record a video of you while you were watching porn. These missives threaten to release the video to all your contacts unless you pay a Bitcoin ransom, and they typically reference a real password the recipient has used previously.

“Noooooo,” the @wristmug account wrote in mock horror after posting a screenshot of the scam message. “I must be done guys.”

In posting their screenshot, @wristmug redacted the username portion of the email address referenced in the body of the scam message. However, they did not redact their previously-used password, and they left the domain portion of their email address (@proton.me) visible in the screenshot.

O5TDEV

Searching on @wristmug’s rather unique 15-character password in the breach tracking service Spycloud finds it is known to have been used by just one email address: cybero5tdev@proton.me. According to Spycloud, those credentials were exposed at least twice in early 2024 when this user’s device was infected with an infostealer trojan that siphoned all of its stored usernames, passwords and authentication cookies (a finding that was initially revealed in March 2025 by the cyber intelligence firm KELA).

Intel 471 shows the email address cybero5tdev@proton.me belonged to a BreachForums member who went by the username o5tdev. Searching on this nickname in Google brings up at least two website defacement archives showing that a user named o5tdev was previously involved in defacing sites with pro-Palestinian messages. The screenshot below, for example, shows that 05tdev was part of a group called Cyb3r Drag0nz Team.

A 2023 report from SentinelOne described Cyb3r Drag0nz Team as a hacktivist group with a history of launching DDoS attacks and cyber defacements as well as engaging in data leak activity.

“Cyb3r Drag0nz Team claims to have leaked data on over a million of Israeli citizens spread across multiple leaks,” SentinelOne reported. “To date, the group has released multiple .RAR archives of purported personal information on citizens across Israel.”

The cyber intelligence firm Flashpoint finds the Telegram user @05tdev was active in 2023 and early 2024, posting in Arabic on anti-Israel channels like “Ghost of Palestine” [full disclosure: Flashpoint is currently an advertiser on this blog].

‘I’M A GINTY’

Flashpoint shows that Rey’s Telegram account (ID7047194296) was particularly active in a cybercrime-focused channel called Jacuzzi, where this user shared several personal details, including that their father was an airline pilot. Rey claimed in 2024 to be 15 years old, and to have family connections to Ireland.

Specifically, Rey mentioned in several Telegram chats that he had Irish heritage, even posting a graphic that shows the prevalence of the surname “Ginty.”

Spycloud indexed hundreds of credentials stolen from cybero5dev@proton.me, and those details indicate that Rey’s computer is a shared Microsoft Windows device located in Amman, Jordan. The credential data stolen from Rey in early 2024 show there are multiple users of the infected PC, but that all shared the same last name of Khader and an address in Amman, Jordan.

The “autofill” data lifted from Rey’s family PC contains an entry for a 46-year-old Zaid Khader that says his mother’s maiden name was Ginty. The infostealer data also shows Zaid Khader frequently accessed internal websites for employees of Royal Jordanian Airlines.

MEET SAIF

The infostealer data makes clear that Rey’s full name is Saif Al-Din Khader. Having no luck contacting Saif directly, KrebsOnSecurity sent an email to his father Zaid. The message invited the father to respond via email, phone or Signal, explaining that his son appeared to be deeply enmeshed in a serious cybercrime conspiracy.

Less than two hours later, I received a Signal message from Saif, who said his dad suspected the email was a scam and had forwarded it to him.

“I saw your email, unfortunately I don’t think my dad would respond to this because they think its some ‘scam email,'” said Saif, who told me he turns 16 years old next month. “So I decided to talk to you directly.”

Saif explained that he’d already heard from European law enforcement officials, and had been trying to extricate himself from SLSH. When asked why then he was involved in releasing SLSH’s new ShinySp1d3r ransomware-as-a-service offering, Saif said he couldn’t just suddenly quit the group.

“Well I cant just dip like that, I’m trying to clean up everything I’m associated with and move on,” he said.

He also shared that ShinySp1d3r is just a rehash of Hellcat ransomware, except modified with AI tools. “I gave the source code of Hellcat ransomware out basically.”

Saif claims he reached out on his own recently to the Telegram account for Operation Endgame, the codename for an ongoing law enforcement operation targeting cybercrime services, vendors and their customers.

“I’m already cooperating with law enforcement,” Saif said. “In fact, I have been talking to them since at least June. I have told them nearly everything. I haven’t really done anything like breaching into a corp or extortion related since September.”

Saif suggested that a story about him right now could endanger any further cooperation he may be able to provide. He also said he wasn’t sure if the U.S. or European authorities had been in contact with the Jordanian government about his involvement with the hacking group.

“A story would bring so much unwanted heat and would make things very difficult if I’m going to cooperate,” Saif said. “I’m unsure whats going to happen they said they’re in contact with multiple countries regarding my request but its been like an entire week and I got no updates from them.”

Saif shared a screenshot that indicated he’d contacted Europol authorities late last month. But he couldn’t name any law enforcement officials he said were responding to his inquiries, and KrebsOnSecurity was unable to verify his claims.

“I don’t really care I just want to move on from all this stuff even if its going to be prison time or whatever they gonna say,” Saif said.
