Lu0bot Malware: Technical Details
The malware has been circling the web for past four months, since February. Its installation is aided by the shady GCleaner program, which security researchers say has been associated with various malware groups. According to an analysis published on Medium by Benoit Ancel, GCleaner is a well-known “load reseller,” or someone malware authors pay to distribute their malware. “Spammers, exploit kit distributors, Pay-Per-Install (PPI) vendors — all of them are just load resellers,” Ancel noted.
In terms of its technical profile, the malware appears to be a lightweight C/C++ program.
Another notable feature is the deployment of various encryption algorithms in its codebase, including XOR, AES-128-CBC, Blowfish, and Diffie-Hellman.
What is lu0bot’s main purpose?
Its primary capability is to harvest data from the infected system, which is a capability most malware nowadays has. However, its dynamic internal structure shows that it can be deployed for various purposes, including backdoor, remote access trojan, infostealer, or a simple malware loader. Due to this complexity, researchers are still uncertain of its original purpose.
