If you’re a fan of Netflix’s Squid Game, be careful around products claiming to be a tie-in with the hit TV show. You may actually be exposing your computer to malware

According to antivirus provider Kaspersky Lab, hackers have been exploiting the Squid Game fandom by seeding the internet with malicious files and phishing scams that pretend to be part of the Korean TV series.

“From September to October 2021, the researchers found several dozen different malicious files on the web with names mentioning Squid Game,” Kaspersky Lab says. “The uncovered threats posing as Squid Game-related content include Trojans, adware, fake streams, and even phishy offers of Halloween costumes.”

The tactic is no surprise; hackers routinely take advantage of the latest fad—whether it be a Hollywood blockbuster, music album, or a PC game—all to trick unsuspecting victims into downloading malware.  

In this case, Kaspersky Lab has been mostly finding Trojan programs that once installed can download additional malware onto the victim’s computer. 

“One of the cybercriminals' schemes worked as follows: the victim was allegedly shown an animated version of the first game from the series, while simultaneously, a Trojan was invisibly launched that could steal data from users’ various browsers and send it back to the attackers' server,” Kaspersky Lab says. “A shortcut was also created in one of the folders, which could be used to launch the Trojan every time the system was started.”

The antivirus provider also noticed one Trojan targeting smartphones by masquerading as an app to watch a Squid Game episode. “This Trojan is distributed in unofficial app stores and various portals under the guise of other popular applications, games, and books,” it says.

The other ruse involves Halloween. The hackers have been setting up fake Squid Game Halloween merchandise stores on the web capable of stealing your money and leaving you with nothing if a purchase is made. “Moreover, targets end up sharing with cybercriminals their banking and personal identity information since they are asked to provide card details and personal data, including an email address, residence address, and full name,” Kaspersky says.

To protect yourself, it’s best to avoid downloading suspicious files to your devices; if you do, use an antivirus product to scan the file before installing. “Check the authenticity of websites before entering personal data and only use official web pages to watch or download movies,” Kaspersky Lab adds. “Pay attention to the extensions of files you are downloading —a video file will never have an .exe or .msi extension."

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.
