Malvertising Campaign Targets Tech Firms with Sophisticated Malware

A newly uncovered cybersecurity threat is impacting details Technology and software development organizations across Western Europe. This campaign utilizes deceptive advertising on search engines, specifically Google, to distribute malware masked as legitimate software, like GitHub Desktop.

Deceptive Tactics: GitHub Links and Altered URLs

Security researchers have identified a particularly cunning tactic employed by the attackers. The campaign embeds malicious code within github commit links, manipulating the underlying URL to redirect users to attacker-controlled websites. Even seemingly legitimate links pointing to GitHub can be altered to lead to counterfeit sites,investigators found. This sophisticated method bypasses initial user scrutiny and endpoint defenses.

GPUGate: A Novel Decryption Technique

The initial stage of the attack delivers a large, 128 MB Microsoft Software Installer (MSI) file. Its considerable size is intended to evade common online security sandbox detections. A unique element, dubbed “GPUGate,” employs a Graphics Processing Unit (GPU)-gated decryption routine. This means the malware payload remains encrypted on systems lacking a dedicated GPU, effectively hindering analysis by security researchers who often use virtual machines-which frequently lack GPUs-for malware examination.

“Systems without appropriate GPU drivers are often virtual machines utilized by cybersecurity professionals,” explained one analyst. “The executable actively verifies the presence and specifications of a GPU before decrypting its payload.”

Attack Chain and Persistence Mechanisms

Upon execution, the malware initiates a Visual Basic Script that then launches a PowerShell script. This script operates with elevated administrator privileges, add Microsoft Defender exclusions, establishes scheduled tasks for persistent access, and finally executes files extracted from a downloaded ZIP archive. The ultimate goals of this complex process are data theft and the deployment of additional malicious payloads, all while actively evading detection.

Cross-Platform Capabilities and Russian Language Links

Analysis of the attacker’s infrastructure revealed connections to Atomic macOS Stealer (AMOS), indicating a cross-platform attack strategy. Investigators also discovered Russian language comments within the PowerShell script, suggesting the involvement of threat actors with native Russian language skills. Recent reports from Akamai show a 60% increase in malvertising campaigns targeting software downloads in the last quarter.

How does Google Ads contribute to the GPUGate malware campaign’s success?

Understanding the GPUGate Malware Campaign

The cybersecurity landscape is constantly evolving, and a recent campaign dubbed “GPUGate” highlights a sophisticated attack vector targeting IT firms. This campaign leverages a combination of malicious code hidden within legitimate-looking GitHub commits and deceptive Google Ads to distribute malware. The primary goal? To compromise systems and steal sensitive data, particularly related to GPU mining and cryptocurrency.This article dives deep into the mechanics of GPUGate, its impact, and how organizations can protect themselves.

The Role of Fake GitHub Commits in Malware Distribution

Traditionally, malware distribution relied heavily on phishing emails or compromised websites. GPUGate demonstrates a shift towards exploiting the trust associated with code repositories like GitHub. Attackers are creating seemingly harmless projects, then injecting malicious code into legitimate commits.

Here’s how it works:

Project Creation: Attackers establish GitHub repositories, often mimicking popular open-source projects or tools used by IT professionals.

Malicious Commit insertion: They subtly insert malicious code into commits, frequently enough obfuscated to avoid immediate detection. This code typically includes a malware downloader or a backdoor.

Social Engineering via Google Ads: This is where Google Ads come into play. Attackers create ads that closely resemble legitimate software download pages or documentation for the compromised projects.

Targeted Advertising: These ads are specifically targeted at IT professionals and developers searching for solutions related to GPU computing, machine learning, or specific software packages.

Download & Execution: Users clicking on these ads are directed to the malicious GitHub repository,unknowingly downloading and executing the compromised code.

This tactic is particularly effective as GitHub is a trusted source for developers,and the malicious commits are frequently enough buried within a history of legitimate changes,making detection difficult. Supply chain attacks are becoming increasingly common, and GPUGate is a prime example.

How Google Ads Facilitate the Attack

The use of Google Ads is a crucial component of the GPUGate campaign. It allows attackers to bypass traditional security measures and directly reach their target audience.

Key aspects of the Google Ads strategy include:

Keyword Targeting: Attackers meticulously select keywords related to GPU drivers, CUDA, OpenCL, TensorFlow, PyTorch, and other technologies commonly used in GPU-intensive applications.

Ad Copy Mimicry: Ad copy is crafted to closely resemble official documentation or download links for the targeted software. This creates a sense of legitimacy and encourages clicks.

Landing Page Deception: The ads lead to the malicious GitHub repository, disguised as a legitimate source.

Bypassing Security Filters: Attackers constantly refine their ad copy and landing pages to evade Google Ads‘ security filters.

The Malware Payload: What does gpugate Do?

The malware deployed through GPUGate varies, but common functionalities include:

Credential Theft: Stealing usernames, passwords, and API keys.

Remote Access: Establishing a backdoor for remote control of the compromised system.

Data Exfiltration: Stealing sensitive data, including source code, customer data, and financial records.

Cryptomining: Utilizing the compromised system’s GPU resources for cryptocurrency mining, often without the user’s knowledge. This is where the “GPUGate” name originates.

Lateral Movement: Spreading the infection to other systems within the network.

The malware often employs techniques like process hollowing and DLL side-loading to evade detection by traditional antivirus software. Rootkit functionality is also frequently observed, allowing the malware to hide its presence on the system.

Impact on IT Firms: Real-World Consequences

The GPUGate campaign has disproportionately impacted IT firms due to their reliance on open-source tools and their frequent use of GPU resources for tasks like AI growth, data science, and rendering.

Potential consequences include:

Financial Losses: Due to data breaches, system downtime, and remediation costs.

Reputational Damage: Loss of customer trust and brand value.

Intellectual Property Theft: Compromise of valuable source code and trade secrets.

Cybersecurity researchers have detailed the inner workings of an Android banking trojan called ERMAC 3.0, uncovering serious shortcomings in the operators’ infrastructure.

“The newly uncovered version 3.0 reveals a significant evolution of the malware, expanding its form injection and data theft capabilities to target more than 700 banking, shopping, and cryptocurrency applications,” Hunt.io said in a report.

Ermac what first documented by ThreatFabric in September 2021, detailing its ability to conduct overlay attacks against hundreds of banking and cryptocurrency apps across the world. Attributed to a threat actor named DukeEugene, it’s assessed to be an evolution of Cerberus and BlackRock.

Other commonly observed malware families – including Hook (ERMAC 2.0), Pegasus, and Loot – possess a shared lineage: An ancestor in the form of ERMAC from which source code components have been passed down and modified through generations.

Hunt.io said it managed to obtain the complete source code associated with the malware-as-a-service (MaaS) offering from an open directory on 141.164.62[.]236:443, right down to its PHP and Laravel backend, React-based frontend, Golang exfiltration server, and Android builder panel.

Cybersecurity

The functions of each of the components are listed below –

  • Backend C2 server – Provides operators the ability to manage victim devices and access compromised data, such as SMS logs, stolen accounts, and device data
  • Frontend panel – Allows operators to interact with connected devices by issuing commands, managing overlays, and accessing stolen data
  • Exfiltration server – A Golang server used for exfiltrating stolen data and managing information related to compromised devices
  • ERMAC backdoor – An Android implant written in Kotlin that offers the ability to control the compromised device and collect sensitive data based on incoming commands from the C2 server, while ensuring that the infections don’t touch devices located in the Commonwealth of Independent States (CIS) nations
  • ERMAC builder – A tool to help customers configure and create builds for their malware campaigns by providing the application name, server URL, and other settings for the Android backdoor

Besides an expanded set of app targets, ERMAC 3.0 adds new form injection methods, an overhauled command-and-control (C2) panel, a new Android backdoor, and AES-CBC encrypted communications.

“The leak revealed critical weaknesses, such as a hardcoded JWT secret and a static admin bearer token, default root credentials, and open account registration on the admin panel,” the company said. “By correlating these flaws with live ERMAC infrastructure, we provide defenders with concrete ways to track, detect, and disrupt active operations.”
