Summary
A sophisticated threat actor targeted more than a dozen sectors around the world with spear-phishing campaigns throughout December 2020. The Doubledrag downloader and Doubledrop dropper were used to infect users with the Doubleback backdoor. The infection process used JavaScript, PowerShell, and Visual Basic for execution and process injection and obfuscation for defense evasion. The malware gathered and exfiltrated a range of data including system, process, software, and account information.
The McAfee Enterprise ATR Team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports.
This campaign was researched by FireEye and shared publicly.
