CikaBika Bot RAT Uses Discord for C&C

SecurityWeek reports Darktrace's findings on CikaBika Bot, a Rust-based RAT delivered via a PDF containing a disk image with an LNK disguised as a Word document. A hidden PowerShell step drops a Nim loader and a Rust DLL that is moved into the protected Edge directory to bypass UAC and sideloaded via DLL search-order hijacking of debugging-library exports. The RAT uses per-victim Discord channels for C&C (recon, command execution, file transfer, screenshots/camera) and exfiltrates ZIPped data via Ngrok.

TL;DR Darktrace: Rust RAT CikaBika Bot arrives via PDF/LNK lure, sideloads a DLL, and uses Discord for C2 and Ngrok for exfiltration.
