Control Message Protocol

A mysterious .zip file has been found, buried inside the chaotic noise of network traffic. Can you find what’s hidden beneath the layers of audio whispers and distracting noise? You are given a .pcap file that contains several kinds of traffic: ICMP, DNS, HTTP... maybe even something more. Will you be able to uncover the whispers and reveal the secret?

In the quiet logs of an internal security tool, something peculiar surfaced — a short capture of routine network traffic. Nothing obviously malicious: just pings, some HTTP chatter, and a handful of anomalies. The analyst reviewing it noted one odd thing: a pattern… too regular to be random, too quiet to be noticed at first glance. Some say the ChronoAnt — a mythical agent of the underground — leaves trails in patterns not seen, but felt. Perhaps you’ll see what others missed. The flag is there. Somewhere between the noise and the silence.

The Rockstar has left traces of his legacy scattered across formats and fragments — a story told in silence, glitches, lyrics, and lost memories.

of a custom cipher. The flag is not printed, not stored in plaintext, and cannot be extracted through direct execution. Your objective is to reverse-engineer the .b source file, understand the internal logic, and recover the hidden flag. The challenge requires a deep understanding of the language semantics, control flow analysis, and cipher reconstruction. Execution of the program will not assist in flag recovery — successful solving will depend entirely on code analysis and manual or scripted deobfuscation.
