- Synology patched a critical remote code execution vulnerability in BeeStation products, demonstrated at Pwn2Own Ireland.
- Gladinet’s Triofox file-sharing and remote-access platform was found to have a critical vulnerability that allowed attackers to exploit the built-in antivirus feature to gain SYSTEM privileges and deploy remote access tools.
- SAP released patches for multiple vulnerabilities, including a maximum severity flaw in SQL Anywhere Monitor due to hardcoded credentials and a critical code execution issue in Solution Manager.
- Adobe released security updates addressing 29 vulnerabilities across multiple products, including InDesign, InCopy, Photoshop, Illustrator, Pass, Substance 3D Stager, and Format Plugins.
- A critical zero-day vulnerability affecting Samsung mobile devices was exploited in the wild to deliver LANDFALL spyware.
- Mozilla introduced new fingerprinting protections in Firefox, reducing the number of trackable users.
- A new side-channel attack, dubbed “Whisper Leak,” allows attackers intercepting network traffic to infer user prompt topics in large language model (LLM) conversations, despite end-to-end encryption.
Notable Threat Actor Activity
- Threat actors are distributing a new banking malware called “Maverick” via WhatsApp, targeting major Brazilian banks. Maverick shares similarities with the Coyote banking malware.
- GootLoader malware has resurfaced, now using a novel font-based obfuscation technique to hide malicious payloads on compromised WordPress sites.
- A malicious npm package, “@acitons/artifact”, was discovered typosquatting the legitimate “@actions/artifact” package, targeting GitHub-owned repositories.
- The Fantasy Hub Android remote access trojan (RAT) is being sold on Russian-speaking Telegram channels as a Malware-as-a-Service (MaaS), turning Telegram into a distribution hub for threat actors.
- Kimsuky (DPRK-linked) APT group is exploiting Google Find Hub to compromise South Korean Android devices, remotely wiping devices and abusing the KakaoTalk messaging app.
- RansomHub ransomware was detected during an in-progress attack, initiated via fake browser updates and leading to domain-admin privilege escalation.
- Scammers are using AI-generated fake faces combined with real body images in extortion scams, and leveraging AI voice cloning and open-source data for social engineering attacks, particularly targeting the elderly.
- Thieves are increasingly phishing Apple ID credentials through fake “Find My” messages to unlock stolen iPhones.
Trends, Tools, or Tactics of Interest
- AI-enabled supply chain attacks increased by 156% over the past year, with CISOs advised to reassess traditional defenses.
- Script-kiddie-level phishing campaigns remain effective at rapidly stealing credentials, even with poorly crafted lures.
- The use of Telegram as a central hub for malware distribution and MaaS offerings is increasing.
- Threat actors are exploiting built-in software features (e.g., antivirus in Triofox) to escalate privileges and deploy malware.
- Fake browser update lures are being used as initial access vectors for ransomware attacks.
- Social engineering attacks are leveraging AI-generated content and public data to bypass human defences.
Regulatory or Policy Developments
- The US Department of Defense began enforcement of Cybersecurity Maturity Model Certification (CMMC) requirements for contractors on 10 November 2025.
- Microsoft announced end of security update support for Windows 11 23H2 Home and Pro editions; extended security updates for Windows 10 are now available.
- Firefox introduced new privacy protections to reduce user tracking.
- Tenzai, an Israeli startup, raised $75 million in seed funding to develop an AI-powered penetration testing platform.
