How to Identify the Precise Vulnerability of Any Linux System
How do Hackers Actually Find Exploits for Linux
In this video we go through every command you need to pull full system and kernel information from a Linux target. uname -a gives you everything in one line — OS type, hostname, kernel version, architecture. cat /etc/issue shows the human-readable OS description that was originally designed to display on login. cat /etc/os-release gives you the distro, version ID, and codename — exactly what you need to search for exploits. And cat /proc/version goes even deeper, showing how the kernel was compiled and which GCC version was used.
We also cover how to actually USE this information — how to search exploitdb, searchsploit, CVE databases and GitHub for kernel exploits specific to the exact version and distro you're on. And we get into why every single number in that kernel version string matters. Major version, minor version, patch number, distro-specific patch count — a vulnerability patched at 4.19.1 is still wide open on 4.19.0.
Dirty Cow gets a first mention here too — a legendary kernel exploit that only works on specific versions. This is exactly how hackers find it.
