  1. Securinets Quals 2026Oct 2026 Silent Tone Three radio transmitters talk over each other on one 433 MHz channel. Read the protocol out of a USB log, repair a logic-analyser recording that silently dropped samples, decode the loud decoy, subtract it, and peel the two quiet transmitters apart to rebuild an encrypted flag. Hard 35 min
  2. Securinets Quals 2026Oct 2026 dumppwn A Windows 11 memory dump caught one second after a kernel exploit ran. Convert the unusual RDMP dump format, spot a fake system process, read its XOR key out of the binary, and decrypt a secret straight out of physical memory, while ten AI-bait decoy flags try to pull you off course. Medium 16 min
  3. Securinets Quals 2026Oct 2026 Gelatino A layered disk-forensics challenge: identify a replaced UEFI loader, reverse its custom byte decoder, turn the recovered shop records into a LUKS passphrase, and decrypt the final OpenSSL recipe. Hard 18 min
  4. Friendly Securinets CTF 2026Sep 2026 Forensics Wave 1 Seven easy-to-medium forensics challenges: header repair, layered encodings, nested archives, a disguised shell archive, low-contrast stego, Morse audio, and a PNG/PDF polyglot. Easy 13 min
  5. Friendly Securinets CTF 2026Sep 2026 Forensics Wave 2 Eighteen intermediate forensics tasks covering Git history, browser artifacts, DNS, maldocs, packet analysis, steganography, and reverse engineering. Medium 34 min

  1. WalkthroughSep 2026 Memory Forensics with Volatility 2 & 3 A complete memory forensics guide: Volatility 2 vs Volatility 3 and when to use each, installation, acquisition, and a full Windows investigation workflow with side-by-side commands for processes, network, injection, files, registry, credentials, timelines, and Linux memory. 37 min
  2. WalkthroughSep 2026 Steganography for CTFs & Forensics A practical steganography guide: a repeatable methodology, then images (PNG/JPEG/GIF/BMP), audio (spectrograms, LSB, DTMF, SSTV), text and whitespace, documents, and password attacks, with the real commands and small Python scripts for each technique. 27 min
