FTC Blocks US Company From Selling 'Stalkerware' Apps

The three apps—MobileSpy, PhoneSheriff and TeenShield—were marketed as products to monitor the smartphone activities of children or employees. But the FTC claims the same apps can be used to spy on unsuspecting users, including people's spouses.

For the first time, the Federal Trade Commission is set to block a US company from selling apps people used to spy on their significant others.

Under a proposed settlement, Florida-based Retina-X Studios will be barred selling three "stalkerware" apps that secretly collected personal details from people's phones, the FTC announced on Tuesday.

The three apps—MobileSpy, PhoneSheriff and TeenShield—were marketed as products to monitor the smartphone activities of children or employees. However, the FTC claims Retina-X made no attempts to ensure the apps were only being used for legitimate purposes.

The subscription-based apps were also quite powerful; once installed, they could collect all the information processed on the smartphone, including chat messages, GPS locations, email and photos—all of which was then sent to Retina-X cloud servers.

In 2017, it was revealed that many Retina-X customers were actually using the apps to spy on their romantic partners after a hacker breached the company's online database and leaked the information stored inside to journalists.

Retina-X

Retina-X previously defended its products as a security solution. But the FTC isn't convinced. Part of the reason is because Retina-X provided instructions to buyers on how to hide the app's icon from a smartphone's home screen, effectively allowing it to run without the smartphone owner knowing about it.

"Although there may be legitimate reasons to track a phone, these apps were designed to run surreptitiously in the background and are uniquely suited to illegal and dangerous uses," FTC Director Andrew Smith said in today's announcement.

"Under these circumstances, we will seek to hold app developers accountable for designing and marketing a dangerous product," he added, hinting at further crackdowns.

The commission is also faulting Retina-X for failing to protect customers' data from the vigilante hackers, who struck in 2017 and 2018 by breaching the company's databases, and eventually wiping the stored information.

According to the FTC, Retina-X sold more than 15,000 subscriptions to all three apps. However, the products also allegedly violated US regulations against unfair and deceptive practices, in addition to the Children's Online Privacy Protection Act, for dropping the ball on protecting customer accounts.

Under the proposed settlement, Retina-X can only continue selling its apps if changes are made to ensure they're used only for legitimate purposes. This includes making the app icons visible on smartphones and displaying a clear notice upon opening that the phone is being monitored. In addition, Retina-X must also undergo third-party audits every two years to assess the company's IT security.

However, the company stopped selling its products in 2018 following the hacks. In a statement, Retina-X thanked the FTC "for its professionalism during the course of the investigation."

Stalkerware Installs Continue

The settlement arrives as antivirus companies have been noticing a rise in stalkerware apps from other providers. Earlier this month, Kaspersky Lab reported an annual 35 percent increase in stalkerware installation attempts on Android devices for a total of 37,000 this year.

Symantec, on the other hand, said its Norton Mobile Security app has seen seeing about 2,000 devices infected with stalkerware each month. Whether the apps were there for legitimate purposes like monitoring a child is unknown. But Symantec told PCMag about 32 percent of consumers who have had a stalkerware app flagged to them have chosen to remove it.

If you suspect your phone has a stalkerware app, you can use antivirus apps from Kaspersky Lab, Symantec, and Malwarebytes to help you detect and remove them. The FTC says clues of a stalkerware infection include a phone battery that drains faster than usual, unexpected charges on your phone bill, o trouble turning off your phone.

"Our stance is that stalkerware is a huge problem," Malwarebytes told PCMag earlier this month. "This is because unlike other malware that just steal data/personal information, stalkerware is directly linked to domestic abuse, and physical harm."

The FTC will decide whether to finalize the Retina-X settlement after a 30-day public comment period.

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.
