What Happened

Analyst Comment
ShinyHunters is a prolific feature of current threat landscape. This adversary appears to have a particular focus on the educational sector. Last month in May 2026, ShinyHunters targeted another provider of educational software: Instructure Canvas. A number of other UK universities were also impacted by the Instructure breach.

The education sector in the US and UK has suffered repeated, significant data breaches in recent years. In January 2025, BleepingComputer reported that PowerSchools, a cloud-based software provider, suffered a breach whereby the data of 62.4 million students and 9.5 million teachers was exfiltrated. Also in June 2026, the University of Oxford also disclosed a data breach impacting its CareerConnect platform. Separately, 13 schools in Powys county in Wales were impacted by a data breach in April 2026.

After the Oracle E-Business Suite zero-day campaign by CLOP in October 2025, this campaign by ShinyHunters against Oracle PeopleSoft is yet another blow for Oracle. Google identified over 100 exposed organisations, and noted that 68% are academic institutions, including universities and colleges worldwide. More are likely to have been victimised by ShinyHunters and listed on their Tor data leak site in the coming weeks.

Defensive Takeaways

• Patch Oracle PeopleSoft: Internet-facing applications, such as file transfer servers or cloud-based software need to be prioritised for patches and updates. Checking the integrity of such systems while patching is also key to finding undetected compromises. Proactively ingesting event logs and threat hunting for suspicious activities involving these systems is also key to prevent breaches.
• Prioritise Education Software Security: Education sector firms or cybersecurity companies with education sector clients must react to the elevated threat, by pen-testing, threat hunting, and threat intelligence sharing. Cybercriminal adversaries like ShinyHunters often exploit internet-facing applications or use stolen credentials for initial access. It is therefore critical to focus on these tactics, techniques, and procedures (TTPs) to prevent their attacks.
• Follow the Data Breach Alert Playbook: Impacted victims must begin to rotate credentials, and start the laborious task of requesting new identity documents and codes like national insurance numbers or passports. It is also worth investing in some credit monitoring services as well to prevent loans being taken out in your name.

What Happened:

• On 3 May 2026, ShinyHunters, the English-speaking adolescent cybercrime collective, claimed they breached Instructure by listing them on their Tor data leak site.
• Instructure is a US-based software provider behind the widely adopted Canvas Learning Management System (LMS). 
• ShinyHunters reportedly exfiltrated 3.65 terabytes of data, spanning 275 million global records from up to 9,000 institutions, before posting extortion messages across university login portals demanding Bitcoin.
• The outage forced prominent UK higher education institutions, including the University of Liverpool, Queen’s University Belfast, and the University of Manchester, to take systems offline and hastily rewrite their end-of-year exam submission schedules.
• Instructure confirmed the affected data includes names, student ID numbers, email addresses, and private student-instructor messages. Instructure also confirmed no passwords, financial data, or government IDs were pilfered.
• When the initial negotiation deadline passed, ShinyHunters then escalated by defacing Canvas login portals at roughly 330 institutions and pivoting to direct school-by-school extortion.
• Following the initial investigation into the breach, Instructure confirmed that ShinyHunters had exploited a vulnerability in its “Free-for-Teacher” account creation system. 
• To prevent the data from being leaked, Instructure announced it had “reached an agreement with the unauthorised actor” behind the data extortion attack.
• According to an expert interviewed by ABC News, while a ransom amount hadn't yet been verified or publicly confirmed, people claiming to have knowledge of the situation estimated the amount was $10 million USD.

Analyst Comment:

Canvas is reportedly the UK’s primary digital learning platform, whose usage grew significantly during the pandemic. The timing of the attack also couldn’t come at a worse time for UK universities. In May, thousands of undergraduate students will be uploading their dissertations and trying to access their course content to prepare for their exams.

Active since 2019, ShinyHunters is a financially motivated data-theft-extortion collective that first emerged publicly in January 2020. Notably, ShinyHunters does not currently deploy ransomware as part of their intrusions. Instead, they exfiltrate data from cloud platforms, software environments, and third-party integrators, then demand a ransom to avoid its public release. SaaS Platforms such as Salesforce, Snowflake, GainSight, SalesLoft Drift and their customers have been targeted by ShinyHunters and adjacent groups in the last couple years.

Instructure is one of the few victims who have likely paid ShinyHunters. Most victims refuse due to not being able to trust that the cybercriminals will stick to their word and delete the stolen data. The consensus across the industry is paying the ransom is never the appropriate option for multiple reasons, such as fuelling future attacks, making your company look like an easy target, and possibly violating sanctions and local ransom payment ban laws. The most likely scenario is that Instructure felt they should pay the ransom to prevent further harm from the release of personal information of millions of students in their system.

Defensive Takeaways:

• Enhance Platform Security: ShinyHunters reportedly exploited a vulnerability in Instructure’s Free-for-Teacher system, which highlights the importance of identity security audits alongside standard application penetration testing. 
• Enhance Logging and Round-the-Clock Monitoring: ShinyHunters reportedly exfiltrated 3.65 terabytes of data from Instructure. Enhanced activity logs and a certified 24/7 SOC monitoring service could have detected these actions by identifying anomalous login events and data exfiltration events to unknown IP addresses. 
• Create and Test Backup Processes: While Canvas was down, the universities shifted to alternative methods like email and printed paper. This case highlights the importance of business continuity plans (BCPs) along with making sure they are updated and tested.
• Be Wary of Second-Order Effects: After a breach of this size, its key to warn users and SOC teams to be vigilant for new waves of phishing emails, brute forcing attacks, and other account takeover methods leveraging the stolen data.
• Never Trust a Cybercriminal: In Instructure’s case, the company says it received “digital confirmation of data destruction (shred logs).” However, as Allison Nixon says, it’s completely unprovable because such shred logs or videos can be easily faked.

An ongoing data extortion attack targeting the widely-used education technology platform Canvas disrupted classes and coursework at school districts and universities across the United States today, after a cybercrime group defaced the service’s login page with a ransom demand that threatened to leak data from 275 million students and faculty across nearly 9,000 educational institutions.

Canvas parent firm Instructure responded to today’s defacement attacks by disabling the platform, which is used by thousands of schools, universities and businesses to manage coursework and assignments, and to communicate with students.

Instructure acknowledged a data breach earlier this week, after the cybercrime group ShinyHunters claimed responsibility and said they would leak data on tens of millions of students and faculty unless paid a ransom. The stated deadline for payment was initially set at May 6, but it was later pushed back to May 12.

In a statement on May 6, Instructure said the investigation so far shows the stolen information includes “certain identifying information of users at affected institutions, such as names, email addresses, and student ID numbers, as well as as messages among users.” The company said it found no evidence the breached data included more sensitive information, such as passwords, dates of birth, government identifiers or financial information.

The May 6 update stated that Canvas was fully operational, and that Instructure was not seeing any ongoing unauthorized activity on their platform. “At this stage, we believe the incident has been contained,” Instructure wrote.

However, by mid-day on Thursday, May 7, students and faculty at dozens of schools and universities were flooding social media sites with comments saying that a ransom demand from ShinyHunters had replaced the usual Canvas login page. Instructure responded by pulling Canvas offline and replacing the portal with the message, “Canvas is currently undergoing scheduled maintenance. Check back soon.”

“We anticipate being up soon, and will provide updates as soon as possible,” reads the current message on Instructure’s status page.

While the data stolen by ShinyHunters may or may not contain particularly sensitive information (ShinyHunters claims it includes several billion private messages among students and teachers, as well as names, phone numbers and email addresses), this attack could hardly have come at a worse time for Instructure: Many of the affected schools and universities are in the middle of final exams, and a prolonged outage could be highly damaging for the company.

The extortion message that greeted countless Canvas users today advised the affected schools to negotiate their own ransom payments to prevent the publication of their data — regardless of whether Instructure decides to pay.

“ShinyHunters has breached Instructure (again),” the extortion message read. “Instead of contacting us to resolve it they ignored us and did some ‘security patches.'”

A source close to the investigation who was not authorized to speak to the press told KrebsOnSecurity that a number of universities have already approached the cybercrime group about paying. The same source also pointed out that the ShinyHunters data leak blog no longer lists Instructure among its current extortion victims, and that the samples of data stolen from Canvas customers were removed as well. Data extortion groups like ShinyHunters will typically only remove victims from their leak sites after receiving an extortion payment or after a victim agrees to negotiate.

Dipan Mann, founder and CEO of the security firm Cloudskope, slammed Instructure for referring to today’s outage as a “scheduled maintenance” event on its status page. Mann said Shiny Hunters first demonstrated they’d breached Instructure on May 1, prompting Instructure’s Chief Information Security Officer Steve Proud to declare the following day that the incident had been contained. But Mann said today’s attack is at least the third time in the past eight months that Instructure has been breached by ShinyHunters.

In a blog post today, Mann noted that in September 2025, ShinyHunters released thousands of internal University of Pennsylvania files — donor records, internal memos, and other confidential materials — through what the Daily Pennsylvanian and other outlets later determined was, in part, a Canvas/Instructure-mediated access path.

“Penn was the named victim,” Mann wrote. “Instructure was the mechanism. The incident was treated as a Penn-specific story by most of the national press and quietly handled by Instructure as a customer-specific matter. That framing was wrong then. It is dramatically more wrong in light of the May 2026 events, which now look like the planned escalation of an attack pattern that ShinyHunters had been working against Instructure’s environment for at least eight months prior. The September 2025 Penn breach was the proof of concept. The May 1, 2026 incident was the production run. The May 7, 2026 recompromise was ShinyHunters demonstrating publicly that the May 2 ‘containment’ did not happen.”

In February, a ShinyHunters spokesperson told The Daily Pennsylvanian that Penn failed to pay a $1 million ransom demand. On March 5, ShinyHunters published 461 megabytes worth of data stolen from Penn, including thousands of files such as donor records and internal memos.

ShinyHunters is a prolific and fluid cybercriminal group that specializes in data theft and extortion. They typically gain access to companies through voice phishing and social engineering attacks that often involve impersonating IT personnel or other trusted members of a targeted organization.

Last month, ShinyHunters relieved the home security giant ADT of personal information on 5.5 million customers. The extortion group told BleepingComputer they breached the company by compromising an employee’s Okta single sign-on account in a voice phishing attack that enabled access to ADT’s Salesforce instance. BleepingComputer says ShinyHunters recently has taken credit for a number of extortion attacks against high-profile organizations, including Medtronic, Rockstar Games, McGraw Hill, 7-Eleven and the cruise line operator Carnival.

The attack on Canvas customers is just one of several major cybercrime campaigns being launched by ShinyHunters at the moment, said Charles Carmakal, chief technology officer at the Google-owned Mandiant Consulting. Carmakal declined to comment specifically on the Canvas breach, but said “there are multiple concurrent and discrete ShinyHunters intrusion and extortion campaigns happening right now.”

Cloudskope’s Mann said what happens next depends largely on whether Instructure’s customers — the universities, K-12 districts, and education ministries paying for Canvas — choose to apply pressure or absorb the breach quietly.

“The history of education-vendor incidents suggests the path of least resistance is the second one,” he concluded.

Update, May 8, 11:05 a.m. ET: Instructure has published an incident update page that includes more information about the breach. Instructure said its Canvas portal is functioning normally again, and that the hackers exploited an issue related to Free-for-Teacher accounts.

“This is the same issue that led to the unauthorized access the prior week,” Instructure wrote. “As a result, we have made the difficult decision to temporarily shut down Free-for-Teacher accounts. These accounts have been a core part of our platform, and we’re committed to resolving the issues with these accounts.”

Instructure said affected organizations were notified on May 6.

“If your organization is affected, Instructure will contact your organization’s primary contacts directly,” the update states. “Please don’t rely on third-party lists or social media posts naming potentially affected organizations as those lists aren’t verified. Instructure will confirm validated information through direct outreach to all affected organizations.”

Update, May 11, 10:16 p.m. ET: Instructure posted an update saying they paid their extortionists in exchange for a promise to destroy the stolen data. “The data was returned to us,” the update reads. “We received digital confirmation of data destruction (shred logs). We have been informed that no Instructure customers will be extorted as a result of this incident, publicly or otherwise.”

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.
