Hackers Phish Finance Organizations Using Trojanized Minesweeper Clone

Introduction

In a concerning development, hackers are leveraging a Python clone of Microsoft’s iconic Minesweeper game to target financial organizations across Europe and the United States. This novel approach involves concealing malicious scripts within the game code, posing a significant challenge to enterprise risk management and endpoint security. As organizations grapple with these evolving threats, Foresiet remains steadfast in its commitment to providing cutting-edge cybersecurity solutions. By integrating robust vulnerability management and online reputation management strategies, companies can enhance their defenses and safeguard their sensitive data and systems.

Attack Overview

According to reports from Ukraine's CSIRT-NBU and CERT-UA, a threat actor identified as 'UAC-0188' is behind these attacks. The hackers are leveraging legitimate code from a Python clone of Minesweeper to disguise Python scripts that download and install the SuperOps RMM, a legitimate remote management software that grants attackers direct access to compromised systems.

Details of the Attack

The attack sequence begins with an email from "support@patient-docs-mail.com," posing as a medical center and featuring the subject "Personal Web Archive of Medical Documents." Recipients are encouraged to download a 33MB .SCR file from a Dropbox link. This file includes harmless code from the Minesweeper clone, but it also contains a malicious Python script that downloads additional malware from a remote source ("anotepad.com").

The inclusion of Minesweeper code within the executable serves as a cover, attempting to make the 28MB base64-encoded string of malicious code appear benign to security software. A function within the Minesweeper code, "create_license_ver," is repurposed to decode and execute the hidden malicious code. This clever use of legitimate software components helps mask and facilitate the cyberattack.

Once decoded, the base64 string assembles a ZIP file containing an MSI installer for SuperOps RMM. This installer is extracted and executed using a static password, granting the attackers unauthorized access to the victim’s computer.

Indicators of Compromise

CERT-UA has identified several indicators of compromise (IoCs) associated with this attack, noting that any organization not using SuperOps RMM should consider its presence or related network activity—such as calls to "superops.com" or "superops.ai"—as indicative of a hacker compromise.
