What you will learn

  • Reading an `auth.log` to tell a brute-force failure wall from the one successful login.
  • Reconstructing an initial web foothold (LFI + webshell) from an nginx access log.
  • Following an attacker's shell history into the persistence they installed.
  • Reading a systemd unit + its script to understand how loot was staged for pickup.
  • Reversing a real-world obfuscation chain: base64 over an XOR with a recovered key.
