Intelligence Profile

According to its author, NimBlackout is an adaptation of the @Blackout project originally developed in C++ by @ZeroMemoryEx, which consists of removing AV/EDRs using the gmer (BYOVD) driver. The main reason for this project was to understand how BYOVD attacks work, and then to provide a valid PoC developed in Nim.

Threat Analysis

NimBlackout is a advanced-sophistication threat actor of undetermined national origin, engaged in cyber operations with a primary motivation of espionage.

The group's espionage-oriented operations suggest a state-sponsored or state-aligned mandate, typically focused on stealing intellectual property, government secrets, or military intelligence. Targets are usually selected for strategic value rather than financial gain.

Classified as an advanced threat actor, NimBlackout likely develops or acquires zero-day exploits, employs custom malware toolchains, and demonstrates long-term persistence capabilities — hallmarks of a well-resourced operation consistent with nation-state backing.
