TeamPCP Backdoors Telnyx PyPI Package Days After LiteLLM Breach

A threat actor known as TeamPCP compromised the Python Package Index (PyPI) “telnyx” SDK less than three days after a previous compromised package incident, publishing versions 4.87.1 and 4.87.2 with malicious backdoors that weren’t in the official repository. The first attempt failed due to a typo, but the fixed release executed payloads that drop persistent malware on Windows or a credential stealer on Linux/macOS. The malware harvests SSH keys, cloud tokens, config files, Kubernetes tokens, and more, exfiltrating it to a command‑and‑control server. Analysis shows reuse of the same cryptographic key and techniques from the earlier LiteLLM compromise, suggesting a linked campaign that targets software supply chain trust in widely used open source packages and can lead to full environment compromise unless credentials are rotated and systems checked.

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/

KEVIntel: Real-Time Intelligence on Exploited Vulnerabilities

KEVIntel is a dynamic platform providing up-to-date information on known exploited vulnerabilities (KEVs). It aggregates data from over 50 public sources, including CISA, and enriches each entry with metadata such as EPSS scores, online mentions, scanner inclusion, and exploitation status. The platform aims to serve as an early warning system, offering insights even before official publications. KEVIntel supports various formats like JSON, CSV, and RSS, facilitating integration into security operations. These entries include CVSS scores, exploit status, and links to proof-of-concept code, aiding organizations in prioritizing remediation efforts.   https://kevintel.com/
