An official configuration tool for a gaming mouse was tampered with to deliver malware to users. On Wednesday, Endgame Gear alerted customers about the threat after a user discovered the tool appeared to be loaded with the Windows-based Xred malware. 

According to Endgame Gear, the product page for the OP1w 4k v2 gaming mouse distributed the malware between June 26 and July 9. “We have since removed the infected file,” the vendor said. “Please note: This issue was isolated to the OP1w 4k v2 product page download only.”

The big question is how the malware was loaded on the site and if Endgame Gear suffered a larger breach. The vendor is still investigating, but says, “access to our file servers was not compromised, and no customer data was accessible or affected on our servers at any time.”

It's unclear how many customers were affected. But the Xred malware operates as a backdoor that can steal data from a PC, secretly hijack the computer, and download other malicious payloads, making it a serious infection. As a result, Endgame Gear is urging impacted customers to remove the identified infected files. The company's security alert has more details.

A Reddit user initially brought up the malware threat last week, warning other Endgame Gear customers “this did not come from a sketchy site or a third-party mirror. It came from the official vendor page.” The user installed the configuration tool and noticed unusual behavior on their PCs, including “Windows error popups,” which prompted them to investigate. 

“This situation is more than just a technical hiccup. It's a serious legal issue, because essentially malware was distributed from their infrastructure," the user added. “Endgame Gear should not be allowed to brush this under the rug.”

Wednesday’s statement finally brings some clarity and accountability after PC review site Igor'sLAB also flagged the threat of malware affecting Endgame Gear’s mouse. The vendor is now apologizing to affected customers and is pledging to bolster its security. "A clean version of the affected file was immediately published as soon as we identified the situation," it said.

Endgame Gear also notes: “All other official sources for our software and firmware, including our main Downloads page (www.endgamegear.com/downloads), our GitHub repository (github.com/EndgameGear), and our Discord channel, were not affected and contained clean files. No other v2 products or their configuration tools were impacted.”

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
