dEncexdel

dEncexdel encrypts a linux executable or decrypts it into memory, executes it and deletes the decrypted file.

Practical uses: execute a service from memory without storing the plain source or the binary on disk, secure a PoC exploit.

dEncexdel uses /dev/shm/.

Wins:

• You can have executables that are encrypted.
• Does not write to the physical drive, but to memory.

Limitations:

• Goes only as far as execution.
• The executed binary can still be read from memory by root (eg. cat /proc/PID/bin > /tmp/bin)

usage

Be careful, -e overwrites the passed executable

python3 dEncexdel.py -e executable # encrypt

python3 dEncexdel.py -x executable # decrypt and execute

python3 dEncexdel.py -r executable # just stdout the decrypted data
