Authorities (CNIL, ANSSI) were notified and an extortion report has been filed while investigations continue.

🔒 Princeton University disclosed a November 10 cyberattack in which threat actors phished an employee and accessed a database used for fundraising and alumni engagement. The attackers exfiltrated biographical information such as names, email addresses, telephone numbers, and home and business addresses for alumni, donors, faculty, staff, and students. University officials say the compromised system did not contain financial data, passwords, or Social Security numbers, and they have blocked the intruders' access while investigating. Affected individuals are urged to verify any communications claiming to be from the university and to avoid sharing sensitive information.

🔒 Anthropic reported that a group it believes to be Chinese carried out a series of attacks in September targeting foreign governments and large corporations. The campaign stood out because attackers automated actions using Claude Code, Anthropic’s AI tool, enabling operations "literally with the click of a button," according to the company. Anthropic’s security team blocked the abusive accounts and has published a detailed report on the incident.

🎧 RTV Noord, a regional Dutch TV and radio broadcaster, reported a cyber incident on November 6, 2025, that blocked staff access to critical systems. Presenters on the "De Ochtendploeg" breakfast show resorted to playing CDs and LPs to stay on air. The attackers left a message on the network, prompting suspicion of ransomware, and the newsroom confirmed internal channels were limited to WhatsApp while services were restored.

🔒 The U.S. Congressional Budget Office confirmed a cybersecurity incident after a suspected foreign hacker breached its network. The agency says it acted quickly to contain the intrusion, implemented additional monitoring and new security controls, and is investigating the scope of the compromise. Officials warned that emails and exchanges between CBO analysts and congressional offices may have been exposed, prompting some offices to halt communications with the agency.

🔒 The Apache Software Foundation says there is no evidence that Apache OpenOffice was breached after the Akira ransomware gang claimed on October 30 that it had stolen 23 GB of corporate documents. The Foundation notes it does not maintain payroll-style employee records or the types of financial and identity documents described, and it has not received a ransom demand. An internal investigation so far has found no compromise and Akira has not published any of the alleged data.

🔐 Nikkei disclosed that unauthorized actors accessed employee Slack accounts after an employee's computer was infected with malware and credentials were stolen. The breach exposed the names, email addresses, and chat histories of 17,368 registered users. Nikkei discovered the incident in September, enforced mandatory password resets, and voluntarily notified the Personal Information Protection Commission, stating that journalist sources and reporting data were not compromised.

🛡️ Rapid, methodical incident response is essential when you suspect unauthorized access. Activating a rehearsed IR plan and notifying a cross-functional incident team (including HR, PR, legal and executives) helps you quickly establish scope, preserve evidence and maintain chain of custody. Contain affected systems without destroying forensic data, protect offline backups, notify regulators, insurers and law enforcement, then proceed to eradication, recovery and hardening.

🔐 A threat actor claims to have compromised University of Pennsylvania systems and exfiltrated data for roughly 1.2 million students, alumni, and donors, including names, dates of birth, contact details, estimated net worth, donation histories, and sensitive demographic data. The attacker said they gained access via a compromised PennKey SSO account and accessed VPN, Salesforce Marketing Cloud, Qlik, SAP, SharePoint, and Box. After access was revoked on October 31 the actor used Marketing Cloud to send offensive emails to about 700,000 recipients and published a 1.7-GB archive of files. Penn says it is investigating; donors should watch for targeted phishing and verify solicitations directly with the university.

🔒 In a filing with the SEC, Ribbon Communications disclosed that unauthorized actors, reportedly tied to a nation-state, had access to its IT network, with initial intrusion activity traced as far back as December 2024. The company detected the breach in September 2025, has worked to terminate access, and is collaborating with third-party cybersecurity experts and federal law enforcement. Ribbon says it has not yet found evidence of material corporate data theft, although attackers accessed customer files on two laptops outside the main network.

🔒 The cyberattack on Jaguar Land Rover in late August forced a global shutdown of IT systems and halted production across its factories. According to the Cyber Monitoring Centre, the weeks-long outage inflicted an estimated £1.9 billion in losses and affected more than 5,000 organizations, including suppliers and dealers. The UK government intervened with guarantees and up to £1.5 billion in support to secure the supply chain as production is gradually resumed.

🔒The Cyber Monitoring Centre (CMC) concluded that the August 2025 cyber-attack on Jaguar Land Rover (JLR) produced an estimated UK financial impact of £1.9bn ($2.55bn) and affected more than 5,000 organisations. The CMC said the vast majority of the cost derived from halted manufacturing after an IT shutdown that stopped production at major UK plants and disrupted suppliers and dealer systems. Analysts ranked the incident a Category 3 systemic event and warned costs could rise if operational technology or intellectual property were compromised. Industry experts called for stronger governmental oversight and for boards to treat cybersecurity as a strategic risk.

🔒 A ransomware attack on contractor Dodd Group reportedly allowed Russian-linked attackers to exfiltrate hundreds of sensitive Ministry of Defence documents, including details on RAF Lakenheath, RAF Portreath and RAF Predannack. The company confirmed an incident and said it contained access, while the MoD suspects the Lynx group is behind the intrusion. Leaked files published on the dark web allegedly include site plans and personnel data, and the case is now under investigation amid a wider rise in UK cyber incidents.

🔒 This weekly recap highlights long-lived, stealthy intrusions and emerging tactics that are reshaping defender priorities. Chief among them, F5 disclosed a year-long breach involving the BRICKSTORM malware and stolen BIG-IP source material, while researchers uncovered new Linux rootkits such as LinkPro and campaigns abusing blockchain smart contracts for malware delivery. The report urges inventorying edge devices, prioritizing patches, and improving detection, baselining, and intelligence sharing.

📊 The Identity Theft Resource Center (ITRC)'s Q3 2025 analysis found 835 publicly reported corporate data compromises in the United States, resulting in approximately 23 million victim notifications. That follows 1,732 incidents in H1 2025 and brings the year-to-date total to nearly 202 million victims. The report attributes 83% of breaches to cyber-attacks, highlights a rise in physical attacks, and criticizes the increasing frequency of notices that omit details about the cause. Major victims this quarter included Anne Arundel Dermatology, DaVita, TransUnion and several large healthcare providers.

🔒 Markus Weber, founder and managing director of dokuworks, describes the immediate steps his team takes when called in after a cyberattack: isolate and secure affected systems so IT forensics can operate, preserve extortion correspondence to help identify perpetrators, assess operational impact, and initiate emergency operations. He warns that ransomware is the predominant threat and generally advises against paying ransoms, though there are rare exceptions. Many organizations are improving technically but still neglect documented emergency organization and trusted external partnerships, leaving them vulnerable.

🔒 F5 disclosed that nation-state attackers breached its systems and exfiltrated portions of BIG-IP source code and information about undisclosed vulnerabilities after gaining persistent access to product development and engineering knowledge platforms. The company says it first detected the intrusion on August 9, 2025, and has found no evidence the stolen data has been exploited or publicly disclosed. F5 reports that its software supply chain was not compromised and no suspicious code modifications were observed, while it continues identifying customers whose configuration or implementation details may have been taken.

🔒 Huntress reports a fresh wave of compromises targeting SonicWall SSLVPN appliances in early October, affecting at least 16 organizations and more than 100 accounts. Attackers are authenticating with valid credentials rather than brute forcing, often from recurring attacker-controlled IPs. Some sessions involved internal reconnaissance and attempts against Windows administrative accounts, but Huntress says it has no evidence linking the activity to September’s MySonicWall cloud backup disclosure. It urges administrators to reset credentials, restrict remote management, review SSLVPN logs, and enable MFA.

🔒 In a coordinated operation, eight suspects attempted to hijack unemployment payments by accessing roughly 20,000 accounts of the Federal Employment Agency (BA) between late January and mid‑March.
