Spyzie, a mobile stalkerware application sharing source code with sibling applications Cocospy and Spyic, suffered a data breach disclosed publicly on February 27, 2025 by TechCrunch following the previous week's disclosure of the underlying shared vulnerability across the three-platform sibling chain. The breach was enabled by a security vulnerability that allowed any party to access the email addresses of customers and the surveillance data captured on monitored devices, with the underlying flaw reported as so trivial to exploit that TechCrunch and the involved security researcher declined to publish the specific details. The researcher exploited the vulnerability to scrape Spyzie customer email addresses and provided the dataset to Have I Been Pwned, which indexed it on February 27, 2025.

The breach affected approximately 518,643 unique Spyzie customer email addresses based on records indexed by Have I Been Pwned. Compromised customer fields were limited to email addresses for purposes of HIBP indexing, but the underlying vulnerability also enabled unauthorized access to captured surveillance data including messages, photos, call logs, and real-time location data from monitored devices. The earliest Spyzie iPhone surveillance records dated back to early 2020. Combined with the sibling Cocospy and Spyic disclosures, the trio breach exposed approximately 3.2 million customer email addresses across all three platforms.

For surveillance targets and customers alike, the practical risk profile is exceptionally severe and varies between the two populations. For surveillance targets (the people whose devices were being monitored), the breach exposed live and historical device data captured by the spyware, with the U.S. National Domestic Violence Hotline (1-800-799-7233) and the Coalition Against Stalkerware providing resources for individuals who suspect they may have been monitored. Android users can detect Spyzie installations by entering ✱✱001✱✱ on the Android phone dialer and pressing call, which exploits a built-in backdoor feature to reveal the otherwise-hidden application; victims should establish a safety plan before removal because disabling the application may alert the person who installed it. For iPhone and iPad users, Spyzie worked by exploiting the victim's Apple Account credentials to access iCloud-stored device backups, and victims should ensure two-factor authentication on their Apple Account and review and remove unrecognized devices from their account. For customers, inclusion in the dataset confirms participation in a stalkerware operation that has now ceased operation, with potential employment, relationship, and legal consequences depending on the jurisdiction and the consent status of the surveillance target.

Spyware platforms collect customer records, target-device identifiers, monitoring settings, and exfiltrated activity data tied to covert mobile surveillance.

Spyzie was taken offline in approximately May 2025 along with sibling stalkerware applications Cocospy and Spyic following the February 2025 breach disclosure. The Spyzie website disappeared, the application stopped functioning, and the FamiSoft Limited operator group's other stalkerware brands (Teensafe, Spyier, Neatspy, Fonemonitor, Spyine, Minspy) were also taken down concurrently. The case was reported by TechCrunch in late February 2025 after the original Cocospy and Spyic disclosure had already been published the previous week, with the security researcher subsequently confirming that Spyzie shared the same easily-exploitable vulnerability. The breach was indexed by Have I Been Pwned on February 27, 2025. Spyzie operators did not respond to TechCrunch requests for comment and have not publicly acknowledged the breach or shutdown.
