Summary Points AI-powered ransomware, PromptLock, has been discovered as a proof-of-concept, capable of performing traditional ransomware functions like data exfiltration and encryption using AI models like GPT-OSS:20b. It is written in GoLang, relies on hard-coded prompts to generate Lua scripts for cross-platform operations on Windows and Linux, and employs the SPECK 128-bit encryption algorithm. Successful deployment of PromptLock would require the victim’s system to run Ollama API locally, and the malware exploits local network requests, but it is not yet fully operational or observed in the wild. The emergence of AI-driven malware signals a new cybersecurity frontier, emphasizing the importance…

Fast Facts Blind Eagle, a persistent threat actor since 2018, has conducted five activity clusters (May 2024–July 2025), mainly targeting Colombian government and various sectors across South America using open-source and cracked RATs, dynamic domains, and legitimate internet services. Their operations involve sophisticated spear-phishing campaigns impersonating government agencies, exploiting compromised email accounts, geofencing, and staging payloads through platforms like GitHub, Dropbox, and Paste.ee to evade detection. The group’s malware deployment often utilizes PowerShell scripts, Visual Basic Droppers, and RATs such as Lime RAT, DCRat, and Remcos, with command-and-control infrastructure relying on Colombian ISPs, VPS, VPNs, and dynamic DNS services. While…
Fast Facts Cephalus is a sophisticated ransomware that exploits unsecured RDP connections and uses DLL sideloading via legitimate security software to evade detection. The malware leverages cloud platforms like MEGA for data exfiltration and deploys complex multi-stage execution to disable system recovery and security protections. It bypasses defenses by executing commands that delete shadow copies, disable Windows Defender, and modify registry entries to prevent detection and tampering. The ransom notes reference past attacks for credibility and urge victims to act fast, emphasizing the importance of MFA, endpoint monitoring, and security best practices for defense. Problem Explained A newly identified and…
