eBPF rootkits 与 Linux 内存取证中的 Volatility 盲点
eBPF(扩展伯克利数据包过滤器)技术虽为 Linux 内核提供了强大的可观测性与安全能力,但也催生了新一代难以检测的 rootkit。由于 eBPF 程序直接运行在内核空间且不修改传统内核数据结构,主流内存取证工具 Volatility 无法有效识别这些恶意负载。本文深入分析了 eBPF rootkits 的工作原理、攻击向量,并探讨了如何改进内存取证技术以应对这一新兴威胁。

A state-designed worm from 2005 called Fast16 sat undetected on VirusTotal for nearly a decade. It intercepted executable files at the kernel level and silently altered floating-point calculations in high-precision engineering software like LS-DYNA, which was used in Iran's nuclear weapons research. Unlike Stuxnet, Fast16 received little public attention for over twenty years.
Paul Graham reports that Y Combinator startups now have over 75% of their code written by AI, a threshold crossed at least one to two years ago. This parallels a similar transformation at Google, where AI-written code went from 0% to 75% in about two years.
Scientists are increasingly concerned about the potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system. Such a collapse could have severe consequences for North America and Europe.
A compromised version of the LiteLLM Python package (version 1.82.8) was briefly available on PyPI, capable of exfiltrating sensitive credentials like SSH keys and cloud secrets. The malicious package affected any project that depended on LiteLLM, though it was only available for about an hour before discovery.
A supply chain attack has compromised the popular npm axios HTTP client library with 300 million weekly downloads. Malicious versions install a remote access trojan, though some users may have avoided infection through version pinning or older installations. Security experts warn this is a live compromise affecting one of npm's most depended-on packages.
