A shocking new investigation has revealed that millions of stalkerware users—and their victims—have been exposed due to a gaping security flaw in three popular spyware apps: Spyzie, Cocospy, and Spyic.
Reported just yesterday by TechCrunch and cybersecurity experts at Malwarebytes, this massive data breach underscores the inherent risks of stalkerware, a type of mobile app marketed as a monitoring tool but often exploited for secretive spying. With over 3 million email addresses compromised and sensitive data like messages, photos, and locations laid bare, this incident is a wake-up call for anyone tempted to use these shady tech tools.
Stalkerware has long been a controversial corner of the tech world, blurring the lines between legitimate parental control and outright invasion of privacy. This latest breach not only jeopardizes the victims being spied on but also turns the tables on the users themselves, exposing their identities and actions. As the fallout unfolds, let’s dive into what happened, why it matters, and what it means for the future of mobile security.
What Is Stalkerware and Why Is It a Problem?
For the uninitiated, stalkerware refers to software or mobile apps designed to secretly monitor someone’s device—think text messages, call logs, photos, and even real-time location tracking. Often disguised as parental monitoring tools, these apps are easily misused, with domestic abusers frequently installing them on a partner’s phone without consent. The result? A chilling breach of privacy that can fuel harassment or worse.

The problem isn’t just ethical—it’s technical. Stalkerware apps like Spyzie, Cocospy, and Spyic are notoriously poorly coded, leaving gaping vulnerabilities that hackers can exploit. This latest breach is a prime example: a simple bug allowed researchers to access back-end databases, exposing not just victim data but also the personal details of the apps’ customers. It’s a double-edged sword—those who spy risk getting caught in their own web.
The Spyzie, Cocospy, and Spyic Breach: What Happened?
On February 28, 2025, TechCrunch broke the story of a vulnerability affecting three stalkerware giants: Spyzie, Cocospy, and Spyic. These apps, which share similar codebases, were found to have a security flaw so straightforward that experts withheld specifics to prevent widespread exploitation. The bug granted access to a staggering amount of data:
- Spyzie: 518,643 unique customer email addresses, plus victim data from over 500,000 Android devices and thousands of iPhones.
- Cocospy: 1.81 million customer email addresses leaked.
- Spyic: 880,167 customer email addresses exposed.
Beyond email addresses, the breach spilled sensitive info harvested from victims’ devices—messages, photos, call logs, and location data. This isn’t the first time stalkerware has sprung a leak; apps like mSpy, pcTattleTale, and TheTruthSpy have faced similar scandals, exposing millions to privacy nightmares. But the scale of this incident—over 3 million users affected across these three apps—sets a grim new benchmark.
How Did This Vulnerability Slip Through?
The short answer: sloppy coding. Stalkerware developers often prioritize stealth and functionality over security, leaving their systems wide open to attack. In this case, the shared codebase between Spyzie, Cocospy, and Spyic meant that a single flaw could compromise all three. Researchers found the bug “easy to exploit,” a damning indictment of the apps’ security practices.
Malwarebytes, a key player in the Coalition Against Stalkerware, has long warned about these risks. Their experts point out that stalkerware’s underground nature—often operating in legal gray zones—means developers cut corners, neglecting the robust safeguards you’d expect from legitimate tech companies. The result? A goldmine for anyone with basic hacking skills, putting both victims and perpetrators at risk.
The Impact on Victims and Users
For victims, the implications are chilling. Imagine your private messages, photos, or daily movements exposed not just to the person spying on you but to anyone who stumbles across this leaked data. In domestic abuse scenarios, where stalkerware is a known tool, this breach could escalate already dangerous situations.
But here’s the twist: the users—the ones installing these apps—aren’t safe either. With millions of email addresses now in the wild, they face potential blackmail, legal repercussions, or public shaming. In most countries, using stalkerware without consent is illegal, except in narrow cases like monitoring minors with parental oversight. This exposure flips the script, turning the hunters into the hunted.
Why You Should Steer Clear of Stalkerware
If you’re tempted to dabble in stalkerware—whether out of curiosity, jealousy, or mistrust—consider this a cautionary tale. Beyond the ethical rot, the practical risks are glaring:
- Legal Trouble: Installing stalkerware without consent is a crime in many places. Courts don’t look kindly on digital stalking.
- Backfire Potential: As this breach shows, your own data could end up in the wrong hands.
- No Real Solutions: Malwarebytes notes that stalkerware rarely resolves issues—it often makes them worse, escalating conflicts when discovered.
Pieter Arntz, in his Malwarebytes post, puts it bluntly: “We have never heard of anyone who was able to solve a problem by using stalkerware.” Instead, the fallout—emotional, legal, or technical—tends to pile on the misery.
How to Protect Yourself From Stalkerware
Worried your device might be compromised? Stalkerware is sneaky, often hiding as a legit app like “System Service” or disappearing from your home screen entirely. Here’s how to fight back:
Scan Your Device
Use a trusted anti-malware tool like Malwarebytes, which specializes in detecting stalkerware. Regular scans can uncover hidden threats that standard antivirus might miss.
Check for Red Flags
Unusual battery drain, sluggish performance, or unfamiliar apps in your settings could signal spyware. On Android, dial 001 and call to reveal hidden apps like Spyzie—then uninstall them.
Secure Your Phone
Lock your device with a strong passcode, enable two-factor authentication, and never leave it unattended where someone could install something shady.
Seek Help Safely
If you suspect abuse-related stalking, don’t remove the app right away—it could alert the spy. Instead, craft a safety plan with groups like the National Network to End Domestic Violence before acting.
The Bigger Picture: Stalkerware and the Tech Industry
This breach isn’t just a one-off—it’s part of a pattern. Since 2017, at least 24 stalkerware operations have been hacked or leaked data, according to TechCrunch. The industry’s lax standards are a ticking time bomb, and companies like Spyzie, Cocospy, and Spyic aren’t rushing to fix the mess. Why? Their quasi-legal status and profit-driven focus leave little room for accountability.
The Coalition Against Stalkerware, backed by firms like Malwarebytes, is pushing back, urging better detection and public awareness. But as mobile tech evolves, so does the spyware arms race. This incident raises tough questions: Should app stores tighten restrictions on monitoring tools? Can regulators crack down harder on these shadowy developers? The stakes—for privacy and safety—are higher than ever.
What’s Next for Stalkerware Victims and Users?
For now, the exposed data is out there, shared with breach notification site Have I Been Pwned to alert affected users. If you’ve used Spyzie, Cocospy, or Spyic—or fear you’ve been a victim—check your email against these leaks. Malwarebytes also offers a free Digital Footprint scan to gauge your online exposure.
Looking ahead, expect more fallout. Hackers could exploit this data for phishing or extortion, while victims may turn to legal action. The stalkerware industry, meanwhile, faces growing scrutiny—but don’t hold your breath for reform from within. These apps thrive on secrecy, and that’s unlikely to change without external pressure.
