A technical walkthrough of the PHP2Shell and Linux kernel exploit chain that rooted 25 servers, covering the telemetry sources and choke points defenders can use to detect web-shell deployment and privilege escalation before attackers reach root.
systemd's official acceptance of Rust for new components marks a real shift in core Linux infrastructure, but C remains the glue for its D-Bus APIs, varlink interfaces, and legacy subsystems that packagers and systems developers still have to navigate.
systemd 262's static PID 1 approach reworks early boot, recovery paths, and immutable-host deployments by stripping runtime dependencies from the init process itself.
An analysis of the RefluXFS Linux kernel vulnerability, explaining how the XFS flaw could lead to root access and what developers can do to harden kernel code against similar bugs.
A developer-focused analysis of the DirtyClone Linux vulnerability, how cloned packets can lead to root access, and the packet-handling hardening steps teams should prioritize.
A deep technical walkthrough of CISA’s warning on an actively exploited Linux kernel improper authentication flaw, covering how to identify affected systems, verify exposure, and apply practical mitigations.
Dirty Frag is a newly disclosed Linux local privilege escalation chain that shows why web teams should treat local-only bugs as high risk when untrusted code, containers, CI runners, and low-privilege access are part of the attack path.
Dirty Frag is a newly disclosed Linux kernel local privilege escalation chain that shows page-cache write bugs in networking and crypto paths can still lead to root on many systems.
Copy Fail is a high-severity Linux kernel privilege escalation flaw that can turn a low-privilege foothold in cloud, CI/CD, or container environments into root access on affected systems.
