Law enforcement agencies in the United States and France have seized two CSAM domains linked to NudeLeaksTeens (NLT), a website that advertised hacked and stolen sexually explicit images and videos of young women and girls for sale. French authorities simultaneously arrested a 25-year-old man in Northern France suspected of being the site's main administrator. The action was announced by the U.S. Attorney's Office for the Eastern District of Virginia (EDVA), the FBI Washington Field Office, and the Cybercrime Division of France's Parquet de Paris. It was carried out under Operation Inevitable, a coordinated effort against the spread of child sexual abuse material (CSAM) and the non-consensual publication of intimate images. The seizure notice now displayed on the sites also references Operation Torch.

What the Seized CSAM Domains Offered

According to the seizure warrant, NLT sold leaked content that had been hacked and stolen from victims. Investigators found that despite warnings on the website against CSAM, the site also offered sexually explicit images and videos of children. [caption id="attachment_114652" align="aligncenter" width="600"] Image Source: FBI[/caption] The site sold content in packages it called "albums" and "collections." Many included victims' personal identifying information alongside explicit material. Some victims have been identified and confirmed to have been minors when the images were created. One package named after the site claimed to contain 6,200 private files of teenagers and adults, mostly American, taken from hacked Snapchat, Instagram, TikTok, and Facebook accounts. Authorities say this collection also contained CSAM.

How the CSAM Domains Were Taken Down

The United States obtained court authorization to seize both domains. Visitors now see a notice stating that the FBI took control of the sites under a seizure warrant issued by the U.S. District Court for the Eastern District of Virginia, citing several federal statutes. The notice carries the insignia of the FBI, the Department of Justice, the Arlington County Police Department, the Parquet de Paris, and the French Gendarmerie's national cyber unit, UNCyber. In France, police arrested a 25-year-old man living in the northern part of the country who is suspected to have been NLT's main administrator. The arrest was carried out at the same time as the seizure of the CSAM domains.

FBI Comments on CSAM Domains Seizure

Darren B. Cox, Assistant Director in Charge of the FBI Washington Field Office, said, "The seizure of these domains represents a decisive step in dismantling the criminal networks that hide behind anonymous online platforms to exploit victims." Cox said the operation cut off the infrastructure used to distribute images and videos obtained by hacking victims' social media accounts, striking at the core of the illicit marketplace. He added that the FBI will continue to act against those who use the internet to cause harm, wherever they operate and whoever they target. The announcement was made by Theophani K. Stamos, First Assistant U.S. Attorney for EDVA; Cox; and Charles "Andy" Penn, Arlington County Chief of Police. The Justice Department's Office of International Affairs provided significant assistance. Assistant U.S. Attorneys April Russo, Lauren Halper, and Meredith Clement are representing the United States.

A Joint Effort Against Online Exploitation

Officials credited cooperation among national, international, and private sector partners for the operation. The case shows how hacked social media accounts can become a source of material sold on illicit sites, affecting both adults and minors.

Japan is stepping up its plans to find cyber attackers who may already be inside the networks that keep essential services running. Under a new fiscal 2027 initiative, the government plans to work with private companies to strengthen Japan threat hunting across critical infrastructure, including power utilities and telecommunications operators. The focus is not only on stopping attacks after they are detected, but on finding signs that an attacker has gained access and is quietly moving through a system without triggering an alert. The government will develop ways to detect these threats and share the methods with private-sector operators, while the Defense Ministry will be able to provide personnel to assist companies when requested.

Japan Threat Hunting to Target Hidden Cyber Threats

The initiative forms part of Japan’s broader active cyber defense efforts. Threat hunting involves actively searching systems for signs of malicious activity rather than waiting for an alert or confirmed attack. Japan’s National Cybersecurity Office plans to use information about potential threats to recreate attack scenarios in a virtual environment. The office will then develop and test detection methods that can be used by private-sector companies. The aim is to help critical infrastructure operators identify attackers that may have already entered their systems and remained undetected. Detecting such activity could also help reduce the risk of a cyberattack disrupting essential services during an emergency. Legislation related to active cyber defense took effect on Thursday, giving the government a framework for expanding these cybersecurity measures.

Defense Ministry to Assist Critical Infrastructure Operators

Japan’s Defense Ministry is also preparing to provide direct support to operators of critical infrastructure. Companies will be able to request assistance, after which the ministry could dispatch personnel with threat-hunting experience developed through the information systems of Japan’s Self-Defense Forces. The National Cybersecurity Office and Defense Ministry have included the related costs in their fiscal 2027 budget requests. Threat hunting can require considerable resources because security teams need to collect and examine large amounts of system event logs. The purpose is to identify unusual activity that may otherwise go unnoticed. NTT Data Japan has been carrying out proactive threat hunting on its own systems since 2024. The company checks system logs for suspicious activity even when there has been no security alert. A representative of the National Cybersecurity Office also said threat-hunting methods could help address ransomware. Such attacks can involve attackers exploring a victim’s systems after gaining initial access, meaning suspicious activity may exist before the ransomware itself is deployed.

Recent Cyberattacks Add to Japan’s Concerns

Japan’s planned expansion of threat hunting comes as cyber incidents have affected government networks and companies across different sectors. In September 2026, the government disclosed that its common infrastructure network had been targeted in a cyberattack that began in May. Digital Minister Hisashi Matsumoto said about 246,000 personal records could have been leaked. The affected Government Solution Service, or GSS, is used by government agencies and independent administrative agencies. The potentially exposed information included about 189,000 employee records and around 57,000 records belonging to businesses and individuals involved in agency operations. An analysis found that a third party had compromised the system by exploiting a bypass involving a virtual private network, or VPN. Other recent incidents have affected private-sector operations. The Nichirei cyberattack in July disrupted food deliveries after the frozen food and logistics company confirmed unauthorized access to its servers. The incident affected logistics operations supporting KFC Japan. Nihon Kotsu also recently reported a malware-related incident that disrupted taxi dispatch services after parts of its IT infrastructure were taken offline. Earlier incidents involving Aflac Japan, KDDI, Sapporo Holdings and Nidec showed that attackers could gain access through subsidiaries, overseas operations or third-party infrastructure. Japan’s fiscal 2027 plans therefore put greater emphasis on looking for attackers that may already be inside a network, rather than relying only on alerts after suspicious activity has become visible.
