💥 Introducing "Dirty Frag" A universal Linux LPE chaining two vulns in xfrm-ESP and RxRPC. A successor class to Dirty Pipe & Copy Fail. No race, no panic on failure, fully deterministic. ~9 years latent. Ubuntu / RHEL / Fedora / openSUSE / CentOS / AlmaLinux, and more. Even if you've applied the "Copy Fail" mitigation, your Linux is still vulnerable to "Dirty Frag". Apply the Dirty Frag mitigation. Details: dirtyfrag.io
@readwithai Correct. Blocked when kernel.yama.ptrace_scope >= 1
New tool: envex — extract and analyze environment variables from running Linux processes. Flags secrets and credentials across all processes using name heuristics, value pattern matching, and entropy analysis. No ptrace or special capabilities required. github.com/bcoles/envex
KASLD v0.1.0 released. New orchestrator runs and cross-correlates leak components to map kernel memory layout. Computes #KASLR slide, entropy bits, and renders virtual/physical memory maps. Now includes prefetch side-channel. github.com/bcoles/kasld
New tool: auth-log-scraper — search Linux auth logs for usernames that look like accidentally typed passwords. 100+ service-specific parsers (SSH, databases, web servers, monitoring, etc.), JSON/CSV output. Vibe coded, so YMMV. github.com/bcoles/auth-lo…
Qualys Threat Research Unit (TRU) discovered CrackArmor: 9 AppArmor flaws impacting 12M+ Linux systems since 2017. These enable root access & container breakouts. Patch your kernels now! Details: bit.ly/4s2c3O4 #Linux #Cybersecurity #CrackArmor"
A Race Within A Race: Exploiting CVE-2025-38617 in Linux Packet Sockets. A step-by-step guide to exploiting a 20-year-old bug in the Linux kernel to achieve full privilege escalation and container escape, plus a cool bug-hunting heuristic. open.substack.com/pub/calif/p/a-…
🎅mongobleed - poc for CVE-2025-14847. Leaks data from mongodb instances due to flaw in zlib message decompression. Reminiscent of heartbleed ❤️
If you're using #Hexstrike Server, be aware that it binds to all interfaces by default (which allows unauth remote command execution). github.com/0x4m4/hexstrik…
Local Privilege Escalation in Fedora Linux (CVE-2025-12744). Red Hat has made this public, but patches aren't out yet. Reliable root for any local user. Mitigation: sudo systemctl disable --now abrtd Writeup + PoC: initblog.com/2025/abrt-root/
Easily detects public rootkits like Singularity and Diamorphine. Not a novel approach. lsrootkit performs similar checks, but is abandoned (since 2018), doesn't compile, and requires root privileges.
I've released Rootkit Signal Hunter - a simple tool which detect rootkits which use signals to elevate process privileges. github.com/bcoles/rootkit…

Big new feature in kernel-hardening-checker: now it supports checking the Linux kernel security parameters for RISC-V ⚡️ (in addition to X86_64, ARM64, X86_32, and ARM). I've spent many weekends on this. Thanks to @_bcoles for the contribution ⭐️ github.com/a13xp0p0v/kern…

@nyxgeek On related note, did you know, that 7z (running as admin), can browse to "PhysicalDrive0" (so \\.\PhysicalDrive0\3.Basic data partition.ntfs\Windows\System32\config\) and copy file from there? SAM is not locked, AV/EDR don't seem to give a damn :)
