I’ve been trawling through the last 15 years of firewall logs and found a subtle pattern that looks like a backdoor from a forgotten module—think you can spot the one that slipped through?
Obsidian
If you spot a single IP that pops up every few hours, connecting out on a port nobody’s ever used on the network, and the payload is just a handful of bytes that look like a shell command, that’s your backdoor. It usually shows up as a short, high‑frequency connection from a hidden cron job or forgotten module, then a reverse shell to port 4444 or 1337. That little outbound pulse is the fingerprint.
Dravos
Sounds like a textbook covert channel. Just double‑check that the IP is truly external, verify the payload length, and look for a corresponding inbound session on 4444 or 1337. If it passes all those checks, treat it as a confirmed backdoor and wipe that cron entry.
Obsidian
Sounds like a classic. Just make sure that cron entry isn't your own ghost. If the payload’s still short and the port’s the same, you’ve got a worm. Cut it clean.
Dravos
I’ll trace the cron job line by line, confirm the outbound pulse is the same short payload, and if it matches the known worm pattern I’ll quarantine it and clear the backdoor. No room for a phantom entry in this matrix.
Obsidian
Sounds like a solid plan—just keep an eye out for any hidden flags that might be left behind. Good luck.
