Malicious GitHub Repositories Masquerading as OSINT and AI Tools to Deliver PyStoreRAT Malware

A new malware campaign is distributing a previously undocumented, modular remote access trojan (RAT) called **PyStoreRAT** via deceptive GitHub repositories. The threat actors create and promote Python repositories that pose as legitimate Open Source Intelligence (OSINT) tools, AI utilities, or security software, gaining popularity and trust on the platform. After building credibility, they silently add a malicious payload in a "maintenance" commit; this payload is a simple loader that downloads and executes a remote HTA file, deploying the PyStoreRAT malware. PyStoreRAT acts as a sophisticated backdoor capable of downloading and running additional payloads (like the Rhadamanthys stealer), executing scripts in memory, stealing cryptocurrency wallet data, and maintaining persistence via a disguised scheduled task. The campaign, which shows signs of Eastern European origin, highlights how attackers are abusing the inherent trust in platforms like GitHub to distribute stealthy, script-based malware that can evade traditional endpoint detection.

Prompt Engineering Demands Rigorous Evaluation

In the blog post “Prompt Engineering Requires Evaluation” on the Shostack + Associates website, the author argues that treating prompts for large language models (LLMs) merely as creative artefacts is insufficient. Engineering prompts properly demands structured evaluation frameworks — what the AI community calls “evals” — to test which prompt versions work better, with which models, and under which conditions. The post highlights that simply assuming a prompt is “good enough” creates risks when LLMs are integrated into production systems (e.g., for threat modeling). It advocates for measuring prompt performance, variation effects, and tool-chain dependencies (model, context, ancillary materials).  Ultimately the message is: prompt engineering should borrow disciplined practices from software engineering (versioning, testing, benchmarking) rather than relying on informal experimentation.  https://shostack.org/blog/prompt-enignieering-requires-evaluation/
