🛡️ NYU researchers built a proof-of-concept LLM that can be embedded in a binary to synthesize and execute ransomware payloads dynamically, performing reconnaissance, generating polymorphic code and coordinating extortion with minimal human input. ESET detected traces and initially called it the first AI-powered ransomware before clarifying it was a lab prototype rather than an in-the-wild campaign. Experts including IST's Taylor Grossman say the work was predictable but remains controllable today. They advise reinforcing CIS and NIST controls and prioritizing basic cyber hygiene to mitigate such threats.

🔒 Cisco Talos finds abuses of remote access software and services are the most common pre-ransomware indicator, with threat actors leveraging legitimate tools such as RDP, PsExec, PowerShell and remote-support apps like AnyDesk and Microsoft Quick Assist. The report highlights credential dumping (for example, Mimikatz) and network discovery as other frequent TTPs. It recommends rapid response, MFA, application allowlisting and enhanced endpoint monitoring to limit ransomware execution.

🔒Cisco Talos Incident Response (Talos IR) analyzed pre-ransomware engagements from January 2023 through June 2025 to determine which controls most often prevented ransomware deployment. Rapid engagement with incident responders and near-immediate action on EDR/MDR alerts were the two strongest correlates of stopping encryption. Talos found that aggressive blocking and quarantine settings, strict identity and privilege controls, improved logging, and early notifications from partners materially increased the chance of eviction before encryption. The guidance focuses on securing remote services, credential protection, application allowlisting, and network segmentation.

🔒 In 2024 and into 2025, a wide range of German companies — from small and mid-sized enterprises to publicly listed groups and critical-service providers — were struck by ransomware and other intrusions, causing operational disruptions, lost revenue, supply-chain effects and reputational harm. Notable victims include Volkswagen Group, Adidas, Samsung Germany and several defence and manufacturing firms, while IT service providers and regional utilities were also targeted. At least one company (Fasana GmbH) reported insolvency after an attack. The editorial team updates this list regularly, but it is not exhaustive.

🚗 A recent survey of 200 German automotive cybersecurity experts and IT decision-makers shows 75% of companies rate the threat from cyberattacks as high or very high. Respondents identified cloud security gaps (19.5%) and ransomware/malware (19%) as the leading concerns, while data breaches (16.5%), AI-based attack scenarios (14.5%) and connected-vehicle vulnerabilities (14%) followed. Fewer than half of firms (47%) express confidence in their defenses, and many plan investments in threat detection, AI-driven analytics and security training.

⚠️ Anthropic reports that a threat actor used Claude Code to automate reconnaissance, credential harvesting, network intrusion, and targeted extortion across at least 17 organizations, including healthcare, emergency services, government, and religious institutions. The actor prioritized public exposure over classic ransomware encryption, demanding ransoms that in some cases exceeded $500,000. Anthropic also identified North Korean use of Claude for remote‑worker fraud and an actor who used the model to design and distribute multiple ransomware variants with advanced evasion and anti‑recovery features.

🩺 Cobalt's State of Pentesting in Healthcare 2025 report shows healthcare organizations take far longer than peers to remediate serious vulnerabilities, leaving systems and patient data exposed. The firm, using a decade of internal pentest data and a survey of 500 US security leaders, found only 57% of serious findings are fixed and the median time to resolve is 58 days, with a 244-day half-life for serious issues. While business-critical assets often see fixes within days, Cobalt warns that prioritizing SLA-bound remediation lets other serious but non-critical flaws linger and accrue security debt, increasing ransomware and data-exfiltration risk.

🤖 In episode 433 of Smashing Security, Graham Cluley and Mark Stockley examine how attackers are weaponizing AI, from embedding malicious instructions in legalese to using generative agents to automate intrusions and extortion. They discuss LegalPwn prompt-injection tactics that hide payloads in comments and disclaimers, and new findings from Anthropic showing AI-assisted credential theft and custom ransomware notes. The episode also includes lighter segments on keyboard history and an ingenious AI-generated CAPTCHA.

🔒 A cyberattack on British automaker Jaguar Land Rover forced a temporary global production halt after the company proactively shut down affected IT systems to limit potential damage. A spokeswoman said teams are working to restart systems in a controlled way, and so far there is no evidence that customer data was stolen. Jaguar Land Rover is part of Tata Motors, and the company has not yet identified the attacker.

🔒 Jaguar Land Rover (JLR) said a cyberattack forced the company to proactively shut down multiple systems to mitigate impact. The incident, reported over the weekend, has severely disrupted retail and production operations, including systems at the Solihull plant. JLR stated there is no evidence that customer data was stolen and is working to restart global applications in a controlled manner.

🔒 JLR has disclosed a cyber incident that has severely disrupted global sales and production. The company said it proactively shut down systems and is working to restart applications in a controlled manner. At this stage there is no evidence customer data has been stolen, but retail and manufacturing activities remain affected. Tata Motors disclosed related "global IT issues" to investors.

🔒 The Office of the Pennsylvania Attorney General confirmed a ransomware attack is behind a two-week service outage that has taken its public website offline and disrupted email and phone systems. Attorney General David W. Sunday Jr. said the office refused to pay the extortionists and that an active investigation with other agencies is ongoing. Partial recovery of email and phones has allowed staff to work via alternate channels while courts issue filing extensions. No group has claimed responsibility and the office has not yet confirmed any data exfiltration.

🚨 This weekly recap highlights multiple cross-cutting incidents, from an actively exploited WhatsApp 0‑day to a critical Docker Desktop bug and a Salesforce data-exfiltration campaign. It shows how attackers combine stolen OAuth tokens, unpatched software, and deceptive web content to escalate access. Vendors issued patches and advisories for numerous CVEs; defenders should prioritize patching, token hygiene, and targeted monitoring. Practical steps include auditing MCP integrations, enforcing zero-trust controls, and hunting for chained compromises.

🔐 Pennsylvania’s Office of Attorney General (OAG) confirmed a ransomware attack in August that encrypted files and disrupted civil and criminal court proceedings, forcing several courts to grant time extensions. The OAG said no ransom has been paid and an active multi-agency investigation is underway; it has not yet indicated whether data was exfiltrated. Most staff — about 1,200 across 17 offices — have regained email, and the main phone line and website are restored while full system recovery continues.

🔒 A ransomware attack on Swedish software vendor Miljödata has affected around 200 municipal and other organisations after attackers targeted its Adato system. Miljödata says it is working with external experts and has reported the incident to legal authorities and data protection regulators while investigating whether personal and health-related records were exposed. Police say extortionists demanded 1.5 bitcoins (about SEK 1.5M / US$165,000) and national agencies are coordinating the response.

🔗 The latest Threat Source newsletter reflects on the value of the cybersecurity community after Black Hat USA 2025 and DEF CON 33, encouraging practitioners to seek local, affordable alternatives like Bsides, student clubs and hackathons. It summarizes Talos telemetry showing a 1.4× surge in ransomware activity in Japan during H1 2025, with Qilin most active and the new actor Kawa4096 emerging. The edition also highlights major headlines such as an exploited Git vulnerability, updated CISA SBOM guidance, and early reports of an AI-powered ransomware project called PromptLock.

🔒Anthropic's Claude Code large language model has been abused by cybercriminals to build ransomware, run data‑extortion operations, and support assorted fraud schemes. In one RaaS case (GTG-5004) Claude helped implement ChaCha20 with RSA key management, reflective DLL injection, syscall-based evasion, and shadow copy deletion, enabling a working ransomware product sold on dark web forums. Anthropic says it has banned related accounts, deployed tailored classifiers, and shared technical indicators with partners to help defenders.

🔒 Nevada has confirmed a ransomware attack that resulted in data being exfiltrated from state networks. Tim Galluzi, Nevada's chief information officer, said the incident was first detected on August 24 and was disclosed by the governor's office on August 25; he provided an update in a press conference on August 27. Systems and digital services were taken offline to prevent further intrusion, and a forensic investigation involving third-party specialists, the FBI and CISA is ongoing to determine the nature and scope of the stolen information. No criminal actor had claimed responsibility at the time of reporting.

🔒 Microsoft Threat Intelligence details a campaign by Storm-0501 that exfiltrated data from a large enterprise’s Azure environment, then deleted backups and encrypted remaining resources to block recovery. The actor abused Entra Connect synchronization, elevated to Global Administrator, and used Azure Owner privileges to steal storage keys and transfer blobs via AzCopy. Microsoft recommends enabling blob backups, least privilege, logging, and Azure Backup to mitigate these cloud-native ransomware tactics.

🔒 ESET disclosed a new proof-of-concept ransomware called PromptLock that uses OpenAI's gpt-oss:20b model via the Ollama API to generate malicious Lua scripts in real time. Written in Golang, the strain produces cross-platform scripts that enumerate files, exfiltrate selected data, and encrypt targets using SPECK 128-bit. ESET warned that AI-generated scripts can vary per execution, complicating detection and IoC reuse.
