What TinyLoad is

TinyLoad v7.4 is an open-source packer and crypter for Windows x64 PE executables. It adds protection layers intended to make executables harder to reverse engineer. A packed file appends the payload to a copy of itself, then extracts, decrypts and runs that payload in memory without writing the original payload to disk. Optional LZ77 compression uses hash-chain matching and a 64 KB sliding window. The custom virtual machine has 28 opcodes in four subtables, and the payload is encrypted with XXTEA. With VEH enabled, pages decrypt when accessed and a watchdog re-encrypts pages untouched for 200 ms. TinyLoad redirects four APIs through wrapper functions and zeroes the payload's import directory after loading. It accepts x64 PE files and requires at least one of VM encryption, compression or VEH. The project is MIT-licensed; source builds use MinGW g++ or build.bat, and precompiled binaries are linked from GitHub Releases. The maker reports nine VirusTotal detections for TinyLoad and files packed with it.
