The FBI raided 40 Texas homes over a North Korean scheme that used fake IT workers to target 70 US companies and generate $3 million. The Justice Department (DoJ) announced coordinated enforcement actions this week targeting North Korea’s long-running scheme to place fake IT workers inside American companies. Two US nationals were arrested, 14 people charged across two separate indictments, and the FBI searched more than 40 residences in Texas, seizing approximately 187 laptops and KVM switch devices. The Texas operation, called Operation Lonestar Roundup, ran between September 21 and 25. The seized devices are the same laptops American companies shipped to their newly hired remote employees, not knowing those IT workers were North Korean intelligence agents using stolen US identities. “Today the Department of Justice announced coordinated actions against the Democratic People’s Republic of North Korea (DPRK) government’s schemes to fund its regime through remote information technology (IT) work for U.S. companies.” states DoJ. “These actions include an indictment, two arrests, searches of multiple known or suspected “laptop farms” in Texas pursuant to “Operation Lonestar Roundup,” and the seizure of approximately 187 computer devices used by DPRK IT workers.” The scheme was simple. North Korean IT workers applied for remote jobs using stolen or fake identities. They used VPNs and proxy servers to make it look like they were working from the United States. American helpers received the laptops provided by employers and installed remote access software so the North Korean workers could use them. These helpers were paid for their role, while the money earned from the jobs was sent back to North Korea through accounts controlled by the regime. According to an indictment from the Northern District of Ohio, the scheme ran from 2019 to mid-2025 and targeted more than 70 US companies across 17 states. The companies operated in sectors including healthcare, communications, cybersecurity support, retail, and manufacturing. “In total, the scheme impacted more than 70 U.S. company employers and generated approximately $3 million in revenue for IT workers.” SoJ states.”The revenue is believed to have been sent to sanctioned entities controlled by the DPRK. Victim employers included companies in the health care, communications, cyber support, retail, and manufacturing sectors across Ohio, sixteen additional states, and the District of Columbia.” The North Korean IT workers earned about $3 million, which prosecutors believe was sent to North Korean entities subject to international sanctions. The authorities warn the scheme is evolving in response to better detection. “Increasingly, North Korean IT workers are turning to recruiting American facilitators to counter improved private sector detections and law enforcement actions.” states DoJ. “These workers are hiring facilitators to complete a wider variety of tasks, and in some cases subcontracting entire jobs to third-party foreign nationals. “ That’s not just using Americans as props. It’s actively outsourcing parts of the operation to people inside the US, which makes attribution harder and interception more complicated. Some IT workers are now subcontracting entire jobs to third-party foreign nationals. Others are hiring facilitators to handle a wider range of tasks beyond just managing the laptops. CrowdStrike, which helped the FBI investigate, tracks the group behind this operation as Famous Chollima and describes the laptop farm infrastructure as vital to overcoming the physical and legal barriers of operating from outside the US. “These laptop farms enabled FAMOUS CHOLLIMA operatives to pose as legitimate remote workers and siphon illicit wages back to their regime while maintaining persistent access to victim organizations. Working alongside the FBI, CrowdStrike’s threat intelligence into the adversary and their operations, and technical analysis helped make these disruptions possible.” states CrowdStrike. “This operation marks the beginning of a broader U.S. law enforcement effort to dismantle FAMOUS CHOLLIMA’s U.S. infrastructure. CrowdStrike’s Counter Adversary Operations team intends to remain an integral part of that effort.” The FBI’s separate public service announcement puts the operation in broader context: “thousands of North Korean state-controlled IT workers” are currently embedded at Western companies, posing what the agency calls a significant national security and intellectual property theft insider threat. North Korean IT workers have individually earned up to $300,000 per year under these schemes, and the collective revenue is measured in hundreds of millions annually, flowing directly to designated entities including the North Korean Ministry of Defense. This is the fifth round of enforcement actions announced since June 2025 under the DOJ’s DPRK RevGen Domestic Enabler Initiative (June 2025, November 2025, April 2026, and May 2026). The initiative targets people in the United States who help North Korean IT workers carry out these schemes. According to CrowdStrike, North Korean hackers were responsible for about half of all documented hands-on cyber intrusions over the past year. The regime is also targeting cryptocurrency exchanges and open-source software projects. In 2025 alone, North Korean attackers stole at least $2 billion in cryptocurrency. The DOJ released a list of email addresses used in these operations, including accounts like randyryang@gmail.com and dev.jerryyang@gmail.com, which companies can add to their screening indicators. The FBI’s public service announcement includes detailed mitigation guidance on spotting DPRK IT worker applications. The red flags are consistent: inconsistencies in work history, reluctance to appear on video, requests to redirect laptop deliveries, and payment accounts that route through intermediaries. “Threats posed by nation-states like North Korea are a stark reminder that our adversaries will go to great measures to exploit our nation’s economic strength to further and fuel their own nefarious agendas,” said U.S. Attorney David M. Toepfer for the Northern District of Ohio. “We are thankful to FBI Cleveland for their incredible work and persistence to put a stop to these bad actors. These charges serve as an urgent alert to all U.S. companies to remain vigilant in their hiring practices.” Follow me on Twitter: @securityaffairs and Facebook and Mastodon Pierluigi Paganini (SecurityAffairs – hacking, IT workers)
ConnectWise has shut down customer access to its Cloud Backup service (formerly SkyKick Cloud Backup) after hackers accessed application identities and compromised Microsoft 365 tenants. Reports of the malicious activity began emerging on Friday, with administrators observing unauthorized access to client data in Microsoft 365 tenants due to a potential “SkyKick/CW breach.” Later on the same day, managed cybersecurity and threat detection platform Huntress confirmed the worries, saying that it had identified at least 162 compromised tenants in its environment. In a post today, Microsoft also confirmed malicious activity involving ConnectWise’s Cloud Backup service, saying it identified unauthorized authentication attempts from an IP address on October 15. ConnectWise’s cloud backup solutions provide backup and recovery services that help managed service providers (MSPs) and IT teams protect and restore customer data, such as emails and files, in cloud environments including Microsoft 365 and Google Workspace.
Drupal has patched two critical vulnerabilities that could allow attackers to execute code remotely on websites running any supported version of the content management system. The security issues impact the software core's Field UI module and the contributed Entity List module. Drupal issued an advance warning at the beginning of the week, urging administrators to apply updates promptly because attackers could develop exploits shortly after the vulnerabilities’ disclosure. “The Drupal Security Team urges you to reserve time for core updates at that time because exploits might be developed within hours or days,” the project's security team warned. “We recommend updating to the latest supported patch (bugfix) release for your site's version of Drupal before October 14, so that you can address any other upgrade issues before the security window.”
U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Fortinet Multiple Products and BeyondTrust Remote Support flaws to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the following vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog: CVE-2025-61624 Fortinet Multiple Products Path Traversal Vulnerability CVE-2026-102764 BeyondTrust Remote Support Authentication Bypass by Spoofing Vulnerability This week, Palo Alto Netwoks researchers reported that PEERSTITCH malware exploited FortiManager to expose 500+ firewalls, evade detection inside FortiOS memory, and maintain stealthy access. The attackers exploited CVE-2025-61624, a path traversal flaw in the FortiOS auto-script engine, to deploy a new implant called PEERSTITCH. The flaw CVE-2026-102764 is an input validation vulnerability in internal components of BeyondTrust Remote Support. BeyondTrust Remote Support is a remote technical support tool that allows IT help desks and support teams to securely access and troubleshoot users’ computers and other devices over a network. From a cybersecurity perspective, the software is important because it can provide privileged access to systems and allow technicians to perform sensitive operations. The components do not properly validate the origin of incoming messages, potentially allowing an attacker to perform file operations on the appliance under certain conditions. “CISA is aware of critical authentication bypass vulnerability CVE-2026-102764 , affecting BeyondTrust Remote Support (formerly Bomgar) versions 26.2.3 and earlier. Patches are available for supported versions (24.3.1 and later); organizations using older versions must upgrade first.” CISA warns. “Cyber threat actors are actively exploiting the vulnerability to gain initial access, then establishing persistence, escalating privileges, and moving laterally. “ According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog. Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure. CISA orders federal agencies to fix the flaws by October 19, 2026.

A cyber incident at a BAE Systems subsidiary just stopped every bankruptcy court in the US from sending notices, and the problem started a week ago. A security incident at BAE Systems Inc., the US subsidiary of British defense contractor BAE Systems, has taken the Bankruptcy Noticing Center offline since October 9. The Bankruptcy Noticing Center (BNC) is the system that federal bankruptcy courts use to send official notices. It handles court notices, messages to creditors, and deadline notifications that keep everyone involved in a case informed. “BAE Systems IT and websites that support the operations of the Bankruptcy Noticing Center (BNC) have been impacted by a cybersecurity incident.” reads the official judiciary statement. “As a result of the incident, all access to the BNC systems and websites that BAE operates on behalf of the judiciary and the related bankruptcy noticing process are unavailable at this time, including bnc.uscourts.gov, bankruptcynotices.uscourts.gov, notices.uscourts.gov, and the National Creditor Registration Service. The incident has also halted the BNC’s production and distribution of bankruptcy notices for bankruptcy courts.” The disruption has prevented the center, which BAE operates on behalf of the federal judiciary, from generating and sending notices to creditors, courts, and attorneys in federal bankruptcy cases across the country. This is not a minor service disruption. The entire notification system used by federal bankruptcy courts across the country is down. “Several online services supporting US federal courts’ bankruptcy systems have gone offline following a cybersecurity incident involving a court contractor, the Administrative Office of the US Courts (AOC) said on Thursday.” Reuters reported. The US judiciary explained that the BNC sends bankruptcy notices for every federal bankruptcy court in the country. Affected domains include bnc.uscourts.gov, bankruptcynotices.uscourts.gov, notices.uscourts.gov, and the National Creditor Registration Service. With that last one down, attorneys using the electronic filing system can’t generate the creditor mailing lists they normally need to serve documents. Courts are still accepting new case filings and electronic notifications to registered attorneys are still going out, but anything tied to the noticing pipeline itself has been dark since last Thursday. A BAE Systems spokesperson said that the company is “aware of a security incident that is isolated to the BNC system” and has taken immediate steps to address it. BAE Systems is “coordinating closely” with the courts on the response, the spokesperson said. Neither BAE nor the judiciary disclosed tachnical details of the incident, whether it was a deliberate cyber attack or a different kind of incident, or whether any data was accessed or taken. The Eastern District of Texas bankruptcy court’s own public notice adds a useful detail: BAE first told the Administrative Office about the problem late on October 9, which means the court system’s administrative leadership knew by that evening. “Late on Friday, October 9, 2026, BAE Systems, the contractor that services the Bankruptcy Noticing Center (BNC), notified the Administrative Office of a service disruption impacting BAE systems that process notices as well as the following websites: bnc.uscourts.gov, bankruptcynotices.uscourts.gov, notices.uscourts.gov, and the National Creditor Registration Service website that supports CM/ECF access to address labels (the mailing matrix).” reads the notice. “Because of this disruption, the court polling and certification drop-off process that supports the delivery of electronic and paper notices has been interrupted and the BNC is unable to provide noticing services to the courts at this time.” Courts started posting disruption notices on October 13, but none of them mentioned a cybersecurity incident at that point, several framed it as a service interruption. The public acknowledgment of the word “cybersecurity” didn’t come until October 15. Summarizing, the incident started on or before October 9. The judiciary’s administrative office learned about it that day. Courts informed users of the problem on October 13, and the public announcement confirming a cybersecurity incident came on October 15. That’s six days between the contractor discovering the problem and the public announcement. During that time, bankruptcy cases across the country continued without the system that sends notices to keep courts, creditors, and lawyers informed. No one has announced when the service might be restored, suggesting the investigation is still at an early stage. This incident highlights a recurring problem: critical systems operated by contractors can fail in a single incident, disrupting services across every federal court handling a specific type of case. The public also waited nearly a week for an official statement. This is not a new pattern, but it keeps happening.

Candiru spyware was delivered to devices at Al Jazeera Media Network via targeted online advertisements in a zero-click attack that required only rendering the malicious ads on the victim's device. Researchers at Citizen Labs investigating the attacks referred to this technique as AdFection, noting that their report is the first public technical confirmation of mercenary spyware delivered through targeted ads. A similar method was documented in late 2025 by Amnesty International, involving ads that infected targets with Predator spyware without them clicking anything. That infection mechanism was called Aladdin and surfaced due to a collection of marketing files and documents leaked from the Intellexa surveillance company that researchers studied and corroborated with technical details from forensic investigations.
Burger King Japan disclosed a breach exposing 11.18 million app users’ personal data after attackers accessed its membership system in early October. Burger King Japan has disclosed a data breach that exposed the personal information of approximately 11.18 million official app members. Burger King Japan, the company operating the fast-food chain in the country, said attackers accessed the system managing customer membership information between October 2 and October 7, 2026. The company disclosed the incident on October 15, after discovering the data leak two days earlier. In its official notice published on October 15, the company confirmed the unauthorized access and apologized to affected customers. The announcement doesn’t identify the attackers or explain how they gained access. BK Japan says it’s working with external security specialists to determine the cause. “We have confirmed that customer membership information from the official app has been leaked externally following unauthorized access by a third party.” reads the data breach notification. The compromised data includes membership IDs, email addresses, names in Japanese characters and kana, phone numbers, dates of birth, gender, prefecture of residence, and membership registration type. The exposed information also indicates whether a customer has a mobile ordering history and whether their email address has been verified. These details can be useful to criminals even without payment data or passwords. Attackers can use them to craft convincing phishing emails, text messages, or phone calls that refer to a customer’s real identity and relationship with Burger King. A message that includes a person’s name, phone number, and other accurate details may look far more credible than a generic scam. Burger King Japan confirmed it does not store credit card numbers and found no evidence that passwords were exposed, with no confirmed cases of fraud so far. However, these factors do not completely rule out the risk of future misuse. According to the company, unauthorized access took place from October 2 through October 7, and the leak was confirmed on October 13. BK Japan says it blocked access from the source of the unauthorized communications as soon as it became aware of the incident. The company has also introduced temporary countermeasures, established an incident response team, and reported the breach to Japan’s Personal Information Protection Commission. It says permanent security improvements, further investigation with external specialists, and email notifications to affected customers are ongoing. “At present, we have confirmed that the unauthorized access was carried out by a third party.” continues the notification. The company has not yet disclosed the precise circumstances that made the intrusion possible, and the investigation is continuing. Until more details emerge, it’s too early to draw conclusions about the initial access vector or attribute the attack to a particular threat actor. Large-scale data breaches create long-lasting risks for follow-on attacks, as criminals can use stolen details for phishing, impersonation, and highly convincing scams. BK Japan urges customers to stay vigilant against fraudulent emails, texts, and calls, warning them never to click unverified links or share sensitive credentials. The core danger is that attackers no longer need network access to cause harm; they can leverage existing stolen data to target customers directly through social engineering. “Please do not access URLs, open attachments, or enter membership information or passwords if you receive a suspicious communication.” concludes the report.
