: Files are often named to mimic routine software updates (e.g., update_v2.0.rar ) or high-value documents to trick users into manual extraction. Technical Analysis of Delivery Mechanisms M0rbius.rar
: Vulnerabilities such as CVE-2025-8088 allow attackers to hide malicious files within an archive that are silently deployed to sensitive system areas (like startup folders) upon extraction. Malicious RAR archives typically use one of three
: Modern Linux-targeted campaigns use filenames containing Bash code .
