E4del and PINHOLE RATs Exploit FTP Banners as Dead Drop Resolvers
A newly identified campaign leverages FTP banners as dead drop resolvers (DDRs) to deliver two previously undocumented remote access trojans, E4del and PINHOLE. Threat actors abuse legitimate FTP services to embed C2 commands within standard banner text, allowing malware to retrieve instructions while blending with normal network traffic. The campaign was reported by The Hacker News on August 25, 2026.
