Windows Cryptomining Attacks Target Graphic Designers High-Powered GPUs

Table of Contents

In a digital age where creativity knows no bounds, graphic designers have unexpectedly become the primary targets of a new and stealthy threat – Windows cryptomining attacks. Cybercriminals have perfected their strategies by exploiting a seemingly legitimate Windows utility known as ‘Advanced Installer’ to infiltrate the computers of graphic designers with cryptocurrency mining malware. This in-depth analysis delves into the intricacies of these attacks, sheds light on their underlying motivations, and offers crucial insights into safeguarding against such threats.

The Deceptive Game: Exploiting ‘Advanced Installer’

At the core of the Windows Cryptomining Attacks lies the crafty utilization of ‘Advanced Installer,’ a genuinely legitimate Windows tool. Attackers skillfully harness this tool to distribute installers for highly coveted 3D modeling and graphic design software, including heavyweights like Adobe Illustrator, Autodesk 3ds Max, and SketchUp Pro. They employ unscrupulous search engine optimization techniques to boost the visibility of these installers, luring unsuspecting victims into their web of deceit.

However, beneath the veneer of these enticing software packages, malicious scripts lie dormant, awaiting their moment to strike. These scripts harbor a sinister payload, comprising remote access trojans (RATs) and cryptomining software.

Windows Cryptomining Attacks: Targeting the Creative Minds

Why do these cybercriminals single out graphic designers for their attacks? The answer lies in the hardware. Graphic designers, along with animators and video editors, frequently rely on computers equipped with powerful GPUs. These GPUs offer high mining hash rates, rendering them prime targets for cryptojacking endeavors. The promise of quick financial gains proves too enticing for these malicious actors to ignore.

Unearthing the Campaign: Cisco Talos’ Vigilance

This meticulously orchestrated campaign came to the fore thanks to the unwavering efforts of Cisco Talos, which has been tracking it since November 2021. The campaign’s impact stretches far and wide, with a significant number of victims hailing from France and Switzerland. However, the United States, Canada, Germany, Algeria, and Singapore have also fallen victim to this insidious plot.

Windows Cryptomining Attacks: Attack Method

Cisco’s analysts have discerned two distinct attack methods at play in this campaign, each with its own unique intricacies and objectives.

First Attack Method

Relies on a batch script named ‘core.bat’ to establish a recurring task.
Executes a PowerShell script tasked with decrypting the final payload, ominously known as ‘M3_Mini_Rat.’
This method is favored when attackers seek discreet and sustained access to victim systems.

Second Attack Method

Introduces two malicious scripts, ‘core.bat’ and ‘win.bat,’ designed to set up scheduled tasks.
The ‘win.bat’ PowerShell script decrypts a downloader script, retrieving a ZIP archive housing the payload (either ‘PhoenixMiner’ or ‘lolMiner’), a secondary PowerShell script, and another encrypted file.
This approach prioritizes swift financial gains but elevates the risk of detection.

Windows Cryptomining Attacks: The Tools of Intrusion: M3_Mini_Rat

The ‘M3_Mini_Rat’ payload equips attackers with remote access capabilities, enabling a range of malicious actions, including system reconnaissance and the installation of additional payloads. This insidious tool endows cybercriminals with potent capabilities, such as system reconnaissance, process management, file system exploration, command and control, file management, data transmission, special checks, and a secure exit.

Windows Cryptomining Attacks: The Cryptocurrency Connection

Two additional payloads, ‘PhoenixMiner’ and ‘lolMiner,’ serve an alternative purpose – cryptocurrency mining. These payloads leverage the computational might of GPUs, specifically those from AMD, Nvidia, and Intel (in the case of ‘lolMiner’). ‘PhoenixMiner’ specializes in mining Ethash-based cryptocurrencies, while ‘lolMiner’ supports multiple protocols, enabling the simultaneous mining of two different cryptocurrencies.

Notably, attackers have imposed constraints to evade detection. Both miners cap GPU power usage at 75% and employ temperature controls to avert overheating. If the GPU temperature exceeds 70 degrees Celsius, mining operations are paused, ensuring attackers maintain a low profile.

Conclusions for Windows Cryptomining Attacks

As this Cryptomining campaign continues to evolve, it serves as a stark reminder of the constantly shifting tactics employed by cybercriminals. Graphic designers and creative professionals, in particular, must remain vigilant to ensure their digital canvases remain untarnished by the hidden threats of Windows Cryptomining Attacks from the cyber world.
