Pikabot

VTCollection    

Introducing Pikabot, an emerging malware family that comprises a downloader/installer, a loader, and a core backdoor component. Despite being in the early stages of development, it already demonstrates advanced techniques in evasion, injection, and anti-analysis. Notably, the loader component incorporates an array of sophisticated anti-debugging and anti-VM measures inspired by the open-source Al-Khaser project, while leveraging steganography to conceal its payload. Additionally, Pikabot utilizes a proprietary C2 framework and supports a diverse range of commands, encompassing host enumeration and advanced secondary payload injection options.
