CoffeeLoader Detection: A New Sophisticated Malware Family Spread via SmokeLoader
- CoffeeLoader is a new sophisticated malware that evades security protection by using advanced evasion techniques and Red Team methods spread via SmokeLoader.
- With over 1 billion malware strains circulating and 300 new malware pieces daily, early detection of emerging threats is crucial.
- SOC Prime Platform offers detection algorithms against CoffeeLoader attacks, compatible with various security solutions and mapped to the MITRE ATT&CK framework.
- Security professionals can hunt for IOCs using Zscaler research and Uncoder AI to transform IOCs into custom queries for SIEM or EDR platforms.
- CoffeeLoader, discovered in September 2024, is designed to download and execute secondary payloads stealthily using unique GPU-based packing techniques.
- The malware samples are packed, with CoffeeLoader mimicking ASUS's legitimate Armoury Crate utility using a packer called Armoury.
- CoffeeLoader establishes persistence via Windows Task Scheduler and uses varied evasion tactics like call stack spoofing, sleep obfuscation, and Windows fibers.
- It employs HTTPS for C2 communication, domain generation algorithms, and certificate pinning if primary C2 channels fail.
- CoffeeLoader, spread through SmokeLoader, shares similarities with it in behaviors like scheduled tasks for persistence and utilizing low-level Windows APIs.
- While a new SmokeLoader version shares some evasion features with CoffeeLoader, the relation between the two remains unclear.
