Stalkerware: A Persistent Privacy Threat
Recently, the Electronic Frontier Foundation (EFF) collaborated with AV Comparatives to examine how well major antivirus apps detect stalkerware on Android devices. This partnership highlights the ongoing risk posed by stalkerware, which comprises applications designed to monitor users without their consent. According to EFF, stalkerware can capture sensitive information like calls, texts, and locations, making it a tool often used in cases of abuse.
Mixed Performance in Detection
The results of their tests in 2025 continued to show varied performance among the leading antivirus apps. Surprisingly, Malwarebytes achieved a perfect detection rate of 100%, while companies like ESET, Bitdefender, McAfee, and Kaspersky managed to detect 94% of stalkerware samples tested. However, both Google Play Protect and Trend Micro lagged with detection rates of merely 53% and 59% respectively. Given that Google Play Protect is the default antivirus for many Android devices, its underwhelming performance raises serious concerns about user safety.
The Decline in Stalkerware Variety
An optimistic development from the tests suggests a decrease in the variety of stalkerware products, with the number tested dropping from 20 in previous years to just 17 in 2025. This reduction may be partly due to growing regulatory scrutiny, which appears to diminish the often hidden nature of such applications.
The Implications for Privacy and Safety
For individuals, especially survivors of abuse, the findings underline the importance of selecting reliable antivirus software. Knowledge of which tools effectively combat stalkerware aids these individuals in safeguarding their privacy and ensuring their safety against surveillance. The EFF hopes that these results will prompt significant improvements from antivirus companies in fighting stalkerware and ultimately protecting users.
1. **Choose Wisely**: Based on detection rates, consider using apps like Malwarebytes that have proven effective against stalkerware.
2. **Stay Informed**: Regularly check for updates on stalkerware and antivirus app performance through EFF and AV Comparatives.
3. **Secure Your Device**: Protect your mobile device with strong passwords and consider using additional security features such as two-factor authentication.
How Government Regulations Shape the Future
The decrease in stalkerware products raises questions about the role of government intervention in tech. Increased regulation may incentivize anti-abuse measures and contribute to safety improvements in apps. It is crucial for users to understand how these measures are enacted and how they can protect rights in an increasingly digital world
Conclusion and Call to Action
As digital privacy concerns continue to evolve, staying vigilant and informed is essential. Your involvement can lead to meaningful change in how we combat stalkerware and enhance our digital security measures. Join organizations like EFF to be part of the movement advocating for better protections against digital abuse.
