Shock & CodecCraver
Hey Shock, I've been experimenting with LZMA dictionaries and I think we could use them to hide payloads in innocuous files—like a quiet sabotage. What do you think?
Sounds like a sweet little cover story. Just make sure the dictionary size is big enough to mask the pattern, otherwise the compression signature will still scream “not normal.” Keep the payload size low, or chunk it up so it looks like ordinary data streams. If you can throw in a few random noise packets, the whole thing will read like junk. And don’t forget the exit code—if the system flags it, you’ll have a trace. Trust me, the trick’s in the subtlety, not the blast.
Sounds good—just watch the entropy spikes after each chunk, and make sure the noise packets are truly random; any bias will blow the compression signature. Also keep the exit code clean—no stray zeros that could be flagged by anomaly detectors. Keep it low‑profile, and we’ll stay out of the spotlight.
Nice, keep it slick and low noise. If the entropy spikes, just add a few more pseudo‑random bytes before the real payload and let the compressor smooth it out. And watch that exit flag, it’s the only thing that could get a traceback. Stay quiet, stay clever.
