Cruciferra Crypter Uses BYOVD and Process Ghosting to Hide Windows Malware
Cruciferra, a sophisticated crypter service linked to a China-based cybercrime group, is being used to deliver remote access trojans (RATs) and information stealers via phishing campaigns. It leverages advanced evasion techniques such as BYOVD, Process Ghosting, and API unhooking to avoid detection and hinder analysis. The threat targets multiple sectors including finance, healthcare, and government, primarily through tax-themed and social engineering lures. The malware establishes persistence via registry modifications and executes payloads in memory to minimize forensic traces.
