In a significant cybersecurity incident, the Android spyware application known as Catwatchful has suffered a major data breach, exposing sensitive information of over 62,000 users and approximately 26,000 victims. This breach has unveiled the extensive reach and invasive capabilities of the spyware, raising serious concerns about privacy and security in the digital age.
Discovery of the Breach
The breach was uncovered by Canadian cybersecurity researcher Eric Daigle in June 2025. Daigle identified a critical vulnerability within Catwatchful’s infrastructure, specifically an unauthenticated PHP API endpoint susceptible to SQL injection attacks. This flaw allowed unauthorized access to the application’s entire user database, compromising email addresses, plaintext passwords, and other personal data. The exposed database revealed that Catwatchful had been operational since at least 2018, with victims primarily located in countries such as Mexico, Colombia, India, Peru, Argentina, Ecuador, and Bolivia.

Functionality and Reach of Catwatchful
Marketed as an undetectable surveillance tool, Catwatchful was designed to monitor Android devices covertly. Once installed, it could access a wide array of personal data, including photos, text messages, call logs, and location information. The spyware also had the capability to remotely activate device cameras and microphones, effectively turning the infected devices into real-time surveillance tools. The spyware’s operation involved a dual-server system: user registration triggered account creation in both Google’s Firebase platform and a custom database hosted on catwatchful.pink. While Firebase provided robust security for storing victim data, the custom server handling user authentication was completely vulnerable.

Exposure of the Operator
The breach not only compromised user and victim data but also exposed the identity of Catwatchful’s operator. The developer behind the spyware was identified as Omar Soca Charcov, a software engineer residing in Uruguay. Charcov’s details, including his personal email, phone number, and even the Firebase web address used to store stolen data, were found in the database. Charcov’s LinkedIn profile used the same email address found in the spyware data. He reportedly also linked his personal email account to the administrator account for Catwatchful, making it easy to trace him as the operator.

Industry-Wide Implications
This incident is part of a troubling trend within the stalkerware industry. In recent years, at least 26 stalkerware companies have been hacked or have leaked customer and victim data online. These breaches highlight systemic security failures across the surveillance software industry, where services collect highly sensitive personal data but consistently fail to implement basic cybersecurity measures to protect either their customers or victims.

Response and Mitigation
Following the discovery, Daigle informed the hosting provider for Catwatchful’s API, which briefly suspended the spyware’s services. However, the API later returned via HostGator. Google added Catwatchful to its Play Protect detection system, but has not yet disabled the Firebase instance storing victim data. Security experts note that Android users can detect Catwatchful by dialing “543210” on their device, which triggers a built-in backdoor revealing the hidden application. The exposed credentials have been added to the Have I Been Pwned breach notification service, allowing affected users to check if their accounts were compromised.

Broader Security Concerns
The Catwatchful breach underscores the inherent risks associated with stalkerware operations. These illicit surveillance tools not only violate personal privacy but also pose significant security threats due to their often lax security measures. The exposure of such a vast amount of sensitive data serves as a stark reminder of the potential dangers posed by these applications.
Recommendations for Users
In light of this breach, users are advised to take proactive steps to protect their devices and personal information:
1. Regularly Review Installed Applications: Periodically check your device for unfamiliar or suspicious applications.
2. Enable Two-Factor Authentication (2FA): Adding an extra layer of security can help protect your accounts even if your credentials are compromised.
3. Use Strong, Unique Passwords: Avoid reusing passwords across different accounts to minimize the risk of multiple accounts being compromised.
4. Keep Software Updated: Regularly update your device’s operating system and applications to ensure you have the latest security patches.
5. Be Cautious with Downloads and Links: Only download applications from trusted sources and be wary of clicking on unknown links, especially from unsolicited messages.
By implementing these practices, users can enhance their security posture and reduce the risk of falling victim to similar spyware applications.
