Digital forensics practitioners, incident responders and *nix system administrators should be aware of programming tools that can aid attackers. It is simple for an attacker to load code when compilers or other tools are installed on a system. In this event, the attacker can simply add any tools that are desired by compiling them on the host. Source code can be uploaded over ASCII connections such as telnet, so even a console can be used to load one’s favorite tools when compilers are installed.
