What Is lu0bot Malware?

lu0bot-malware-trojan-removal-sensorstechforumLu0bot is a new malware recently discovered by security researchers.

First spotted in the wild about 4 months ago, lu0bot has been described as “curious lightweight payload”.

Evidently, the malware emerged in February 2021, while it was being installed as a second-stage payload via GCleaner, a dubious software. “Currently, it seems that lu0bot is pushed by the well-known load seller Garbage Cleaner on EU/US Zones irregularly with an average of possible 600-1000 new bots (each wave), depending on the operator(s) and days,” said Fumik0_, the cybersecurity researcher who analyzed the malware in depth.

Currently, 43 out 70 security engines on VirusTotal detect lu0bot. Some of its detections include Win32:Malware-gen (AVG), Generic.mg.0fd2355a4674cd4a (FireEye), W32/Runner.IXI!tr (Fortinet), Win32:Malware-gen (Avast).

Lu0bot Malware: Technical Details

Distribution
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.

Technical overview
In terms of its technical profile, the malware appears to be a lightweight C/C++ program.

However, it is designed to download and install the Node.js server on infected machines. At a next stage, lu0bot will use a complicated set of multi-layered JavaScript code to conceal its true purpose and functionality. This is also done to baffle security researchers and reverse engineers… Something the malware has certainly succeeded to achieve.

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.
