* A program that automates the APT38 technique, which has been utilized to target cybersecurity researchers experts

* Lazarus is a state-sponsored group affiliated with North Korea, has a well-documented track record of targeting cybersecurity researchers. Among their notable techniques, one stands out for its effecti in tricking numerous cybersecurity experts.
* The attackers create multiple Twitter and other social media accounts to establish credibility. Through social engineering tactics, they manipulate security researchers into engaging in collaborati using a Microsoft Studio Project, the project contains a malicious code in the file. Consequently, when the researcher attempts to build the project, the malicious code embedded within it is executed.

Attack Scenario: De En Supply Chain Attack

An attacker sends a malicious Studio project to a de, the de opens the project, appearing to be a legitimate code sample, Upon first build, the program infects ALL Studio projects on the de's system

The infected de continues normal work, modifying and sharing projects with colleagues and each shared project carries the infection to new de machines and when colleagues open and build these projects, their en become infected the infection continues to spread across the de team

Impact

In a successful campaign, this will create a catastrophic compromise of the entire de ecosystem .

technical Details

This analysis is based on information shared by both Google Threat Analysis Group and a security researcher Joel Eriksson who documented their experience with this attack. Their tweet highlighted effecti measures:

Initial Approach

* Create believable security researcher personas on social platforms and Build trust through technical con

* Target actual security researchers through direct messages and Offer collaboration on "proof of concept" projects

Delivery Mechanism

* Send encrypted ZIP files containing Studio projects and claim the projects demonstrate interesting
Mention encryption to appear security-conscious

Use small file sizes (452.13KB) to seem like legitimate code projects

Execution Method

Hide malicious PowerShell commands within Studio project files the powerShell commands execute with bypassed execution policy and hidden windows
Include OS checks that :

* Windows 10 is running (os..major -eq 10)
* System is 64-bit (is64bitoperatingsystem)
* A specific path exists (Test-Path x64\Debug\Browse.VC.db)

Key technique: Use rundll32 to load malicious code from a file disguised as a Studio database file and call a specific exported function ENGINE_get_RAND with two parameters:
A 16-character string that appears to be a key/identifier: 6bt7cJNGEb3Bx9yK
A numeric value: 2907

APT38-0day-Stealer technical Details

* Upon execution within the Studio projects directory, the program infects all files by injecting custom code. This code is designed to execute when the indi attempts to build the project .
