In December 2024, Palo Alto Unit 42 researchers uncovered an attack chain that employs distinct, multi-layered stages to deliver malware like Agent Tesla variants, Remcos RAT or XLoader.
Attackers increasingly rely on such complex delivery mechanisms to evade detection, bypass traditional sandboxes, and ensure successful payload delivery and execution. The phishing campaign we analyzed used deceptive emails posing as an order release request to deliver a malicious attachment. This multi-layered attack chain leverages multiple execution paths to evade detection and complicate analysis.
