Fast Facts ESET discovered PromptLock, an AI-powered ransomware written in Golang that uses OpenAI’s gpt-oss:20b model locally to generate malicious Lua scripts for cross-platform encryption, exfiltration, and filesystem enumeration. PromptLock leverages AI-generated Lua scripts with variable IOCs, complicating detection efforts, and is currently considered a proof-of-concept, utilizing SPECK 128-bit encryption to lock files, with potential to also exfiltrate or destroy data. The malware operates without downloading the full AI model, instead establishing a proxy to a server with the Ollama API, indicating a new approach that enhances its stealth and potential for deployment. The emergence of PromptLock highlights how AI…

Fast Facts Infostealers, part of malware-as-a-service (MaaS), have evolved into sophisticated, stealthy tools that silently exfiltrate vast amounts of personal and corporate data, fueling cybercrime, fraud, and targeted intrusions. Their rapid, covert operations involve phishing via fake CAPTCHAs, memory-based malware delivery, and encrypted data exfiltration, making detection difficult and enabling quick, untraceable theft. The stolen data, packaged into logs, is widely sold on underground markets, used for credential theft, lateral network movement, extortion, or access to cloud and enterprise assets. The increasing prevalence and efficiency of infostealers pose significant security risks, with incidents like the 2024 Snowflake breach highlighting their…
