Volana - Shell Command Obfuscation To Avoid Detection Systems

Volana provides a means to obfuscate shell commands, evading detection by security monitoring systems. It operates by offering a self-contained shell runtime that executes commands without leaving traces during execution. To use Volana, an interactive shell is necessary and the tool can be downloaded and executed on the target machine. Commands entered into the Volana console are stealthily executed, with options to enable "ring mode" for further obfuscation and to exit from non-interactive shells. Volana also provides encryption functionality, allowing encrypted commands to be transferred and decrypted on the target machine, granting access to an interactive shell. Base64 encoding is avoided to prevent detection, and Volana primarily conceals its launching command while leaving the executed command exposed. Volana does not offer complete invisibility but aims to hinder intrusion detection and investigation. It evades detection by bypassing history command output, history files, bash debug traps, and sudo logging. Detection is possible through unknown command alerts, keyloggers, syslog files, and syscall analysis. Volana can be avoided by identifying its launching command or by monitoring unknown syscalls. No monetary reward is offered for contributions, but feedback on detection methods is encouraged.
