Security Firms Clash Over CVE Credit and Disclosure

🔍 A public dispute erupted when FuzzingLabs accused Y Combinator-backed Gecko Security of copying proof-of-concepts (PoCs), resubmitting them for CVEs, and backdating blog posts to claim credit. FuzzingLabs cites two specific flaws — an Ollama token-stealing bug and a Gradio arbitrary file-copy/DoS issue — and says unique markers in its PoCs prove plagiarism. Gecko denies wrongdoing, saying its process involves direct coordination with maintainers and that overlaps were accidental; it has since updated posts to credit FuzzingLabs.

AI in Today's Cybersecurity: Detection, Hunting, Response

🤖 Artificial intelligence is reshaping how organizations detect, investigate, and respond to cyber threats. The article explains how AI reduces alert noise, prioritizes vulnerabilities, and supports behavioral analysis, UEBA, and NLP-driven phishing detection. It highlights Wazuh's integrations with models such as Claude 3.5, Llama 3, and ChatGPT to provide conversational insights, automated hunting, and contextual remediation guidance.

AI-Generated Ransomware 'PromptLock' Uses OpenAI Model

🔒 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.

ESET Finds PromptLock: First AI-Powered Ransomware

🔒 ESET researchers have identified PromptLock, described as the first known AI-powered ransomware implant, in an August 2025 report. The Golang sample (Windows and Linux variants) leverages a locally hosted gpt-oss:20b model via the Ollama API to dynamically generate malicious Lua scripts. Those cross-platform scripts perform enumeration, selective exfiltration and encryption using SPECK 128-bit, but ESET characterises the sample as a proof-of-concept rather than an active campaign.
