ClickFix Deno Abuse to CastleRAT

Description

Activity began with a ClickFix-style social engineering chain that led to MSI execution, PowerShell staging, and installation/use of Deno to run attacker-controlled JavaScript. Follow-on activity downloaded a portable Python runtime, `install.pyc`, and an encrypted `.MOa` container, which was later decrypted to recover a 64-bit Windows PE payload. Analysis of the recovered payload showed Steam Community being used as a dead-drop resolver for C2, with the profile title resolving to `smokeenew[.]com`, while `ip-api.com` was used for victim network/geolocation profiling. The payload also contained logic for browser/wallet data collection, clipboard/keylogging-related capabilities, Defender exclusions, UAC bypass/relaunch behavior through `ComputerDefaults.exe`, and a C2-tasked mechanism to receive and install an additional `Krutyak.zip` / `usbmmidd_v2` component. Recommendations: Block artifacts where applicable.
