Linux ELF binary debugging and anti-debugging - Aczid

I sometimes partake in Wargame/CTF activities, and am professionally
involved in security drills employing a harmless malware which
makes use of anti-debugging techniques. In both these capacities I've
picked up the basics of debugging and anti-debugging techniques for
Linux ELF binaries. GDB, readelf, ptrace/strace, anti-ptrace,
anti-anti-ptrace. Actually, there's one useful (offensive) trick in
particular I've come across independently that appears to be widely
unknown. (Although I might prefer to keep it to myself! ;))
