Percino

Evasive Golang Loader

Percino is a Golang loader that execute shellcode utilizing the process hollowing technique with anti-sandbox and anti-analysis measures. The shellcode is encrypted with the Triple DES (3DES) encryption algorithm.

Full EDR bypass with any C2 Framework. Tested with Cobalt Strike against MDE EDR.

Key Features: - 3DES Encryption - Sandbox Evasion - Analysis Evasion - Execution delay - Process Hollowing

TIP: I recommended to sign the binary with CS
