Stalkerware is commercially available software used to spy remotely on another person via their device, without the victim giving their consent or being notified. In its Stalkerware Test 20201, AV-Comparatives, an independent Austrian-based industry testing organization, teamed up with Electronic Frontier Foundation (EFF), the leading US-based nonprofit organization defending digital rights, to review the most used antivirus programs - including Kaspersky’s Internet Security solution for Android and Windows. 10 security solutions were tested using 20 stalkerware apps for Android and 10 stalkerware programs for Windows, first in November 2019 and then again in May 2020.

Looking at the Stalkerware Test 2020 results, Kaspersky’s Internet Security solution for Android devices performed best-in-class, with a 95% detection rate both in November 2019 and May 2020. The solution also achieved strong results for protecting Windows’ devices, reaching a 100% detection rate in the second round of testing. Tests were conducted to see if the product showed either a warning or detection message to the user’s device or blocked the stalkerware. If the antivirus product performed either of these functions, then it was considered to have successfully detected the stalkerware.

“We are working hard to achieve the best results possible in detecting stalkerware and are determined to continue doing so, as this type of software has an immense and harmful impact on people’s lives. It is also due to the remarkable work by the Coalition Against Stalkerware that stalkerware detection rates have improved for the whole industry within just six months. As part of this global alliance, which coordinates the work of cybersecurity vendors to exchange stalkerware information and improve detection rates, we also work with members from support organizations to tackle the societal dimension of the problem,” comments Vladimir Kuskov,Head of Advanced Threat Research and Software Classification, Kaspersky.

For users who suspect they may be affected or who are being impacted by stalkerware, Kaspersky has the following recommendations:

  • Contact local support organizations or the police, to receive professional assistance if you are concerned about or have found stalkerware on your device. The Coalition Against Stalkerware website provides a list of support organizations2
  • Visit and watch an explanatory video by the Coalition Against Stalkerware - both of which are available in six languages (English, French, German, Italian, Portuguese and Spanish) - to find helpful information for victims and survivors to better understand and detect the warning signs of stalkerware. The video lists common indicators to check if a user thinks they may have become a victim of stalkerware, and what steps they should and should not take
  • Use proven cybersecurity protection, such as Kaspersky Internet Security, to run a check on your device and discover if stalkerware has been installed on it
