Killsuit How The Equation Group Remained Out Of Sight

Lacie Fan

When the shadow brokers released a large number of Equation Group tools in 2017, many researchers jumped on the analysis of EternalBlue, FuzzBunch etc. The exploits of the leak have now been thoroughly analysed and mo...

Summary

### Dissecting the Equation Group's Killsuit Framework At 00:00, threat hunters Connor Morley and Lacie Fan present an in-depth reverse-engineering analysis of Killsuit, a highly sophisticated persistence and stealth framework attributed to the Equation Group, at the Blue Team Village.

### In-Memory Injection and Process Hijacking At 04:57, the speakers examine Killsuit's execution flow. Tracing memory allocations, they illustrate how the framework injects malicious payloads into legitimate system processes without dropping executable binaries onto physical storage, evading conventional antivirus file scanners.

### Anti-Analysis Techniques and Encrypted Registry Storage At 09:35, the presentation explores Killsuit's multi-layered defense mechanisms. The implant incorporates sophisticated anti-debugging checks and stores its modular component library encrypted directly within undocumented Windows registry keys, leaving static disk analysis ineffective.

### The pel_cheap Modular Loader Mechanism At 14:02, Morley and Fan detail the internal mechanics of the `pel_cheap` loader. When an operational action is triggered, `pel_cheap` retrieves encrypted payload blobs from registry containers, decrypts them in volatile memory, and executes modular functionality entirely in RAM.

### Silent Error Suppression and Memory Hunting Strategies Concluding between 19:58 and 25:58, the researchers reveal that Killsuit actively suppresses operating system error notifications to avoid alerting system administrators. They share actionable blue team hunting strategies, including YARA rules and memory scanning techniques to detect unbacked executable memory regions.
