 The state of stalkerware in 2022 (PDF)

Main findings of 2022

The State of Stalkerware is an annual report by Kaspersky which contributes to a better understanding of how many people in the world are affected by digital stalking. Stalkerware is a commercially available software that can be discretely installed on smartphone devices, enabling perpetrators to monitor an individual’s private life without their knowledge.

Stalkerware can be downloaded and easily installed by anyone with an Internet connection and physical access to a smartphone. A perpetrator violates the victim’s privacy as they can then use the software to monitor huge volumes of personal data. Depending on the type of software, it is usually possible to check device location, text messages, social media chats, photos, browser history and more. Stalkerware works in the background, meaning that most victims will unaware that their every step and action is being monitored.

In most countries around the world, the use of stalkerware software is currently not prohibited but installing such an application on another individual’s smartphone without their consent is illegal and punishable. However, it is the perpetrator who will be held responsible, not the developer of the application.

Along with other related technologies, stalkerware is part of tech-enabled abuse and often used in abusive relationships. As this is part of a wider problem, Kaspersky is working with relevant experts and organizations in the field of domestic violence, ranging from victim support services and perpetrator programs through to research and government agencies, to share knowledge and support professionals and victims alike.

2022 data highlights

  • In 2022, Kaspersky data shows that 29,312 unique individuals around the world were affected by stalkerware. Compared to the downwards trend that has been recorded in previous years, this is similar to the total number of affected users in 2021. Taking into account the developments in digital stalking software over the past few years, the data suggests there is a trend towards stabilization. More broadly, it is important to note that the data covers the affected number of Kaspersky users, with the global number of affected individuals likely to be much higher. Some affected users may use another cybersecurity solution on their devices, while some do not use any solution at all.
  • In addition, the data reveals a stable proliferation of stalkerware over the 12 months of 2022. On average, 3333 users each month were newly affected by stalkerware. The stable detection rate indicates that digital stalking has become a persistent problem that warrants wider societal attention. Members from the Coalition Against Stalkerware estimate that there could be close to one million victims globally affected by stalkerware every year.
  • According to the Kaspersky Security Network, stalkerware is most commonly used in Russia, Brazil, and India, but continues to be a global phenomenon affecting all countries. Regionally, the data reveals that the largest number of affected users can be found in the following countries:
    • Germany, Italy, and France (Europe);
    • Iran, Turkey, and Saudi Arabia (Middle East and Africa);
    • India, Indonesia, and Australia (Asia-Pacific);
    • Brazil, Mexico, and Ecuador (Latin America);
    • United States (North America);
    • Russian Federation, Kazakhstan and Belarus (Eastern Europe (except European Union countries), Russia and Central Asia).
  • Globally, the most commonly used stalkerware app is Reptilicus with 4,065 affected users.


The data in this report has been taken from aggregated threat statistics obtained from the Kaspersky Security Network. The Kaspersky Security Network is dedicated to processing cybersecurity-related data streams from millions of volunteer participants around the world. All received data is anonymized. To calculate the statistics, the consumer line of Kaspersky’s mobile security solutions has been reviewed according to the Coalition Against Stalkerware’s detection criteria on stalkerware. This means that the affected number of users have been targeted by stalkerware only. Other types of monitoring or spyware apps that fall outside of the Coalition’s definition are not included in the report statistics.

The statistics reflect unique mobile users affected by stalkerware, which is different from the total number of detections. The number of detections can be higher as stalkerware may have been detected several times on the same device of the same unique user if they decided not to remove the app upon receiving a notification.

Finally, the statistics reflect only mobile users using Kaspersky’s IT security solutions. Some users may use another cybersecurity solution on their devices, while some do not use any solution at all.

Table 8 – Top 10 list of stalkerware applications in 2022

Stalkerware provides a means to gain control over a victim’s life. Their capabilities vary depending on the type of application and whether it has been paid for or obtained freely. Typically, stalkerware masquerades as legitimate anti-theft or parental control apps, when in reality they are very different – most notably due to their installation without consent and notification of the person being tracked, and their operation in stealth mode on smartphone devices,

Below are some of the most common functions that may be present in stalkerware applications:

  • Hiding app icon
  • Reading SMS, MMS and call logs
  • Getting lists of contacts
  • Tracking GPS location
  • Tracking calendar events
  • Reading messages from popular messenger services and social networks, such as Facebook, WhatsApp, Signal, Telegram, Viber, Instagram, Skype, Hangouts, Line, Kik, WeChat, Tinder, IMO, Gmail, Tango, SnapChat, Hike, TikTok, Kwai, Badoo, BBM, TextMe, Tumblr, Weico, Reddit etc.
  • Viewing photos and pictures from phones’ image galleries
  • Taking screenshots
  • Taking front (selfie-mode) camera photos

Are Android OS and iOS devices equally affected by stalkerware?

Stalkerware tools are less frequent on iPhones than on Android devices because iOS is traditionally a closed system. However, perpetrators can work around this limitation on ‘jailbroken’ iPhones, but they still require direct physical access to the phone to jailbreak it. iPhone users fearing surveillance should always keep an eye on their device.

Alternatively, an abuser can offer their victim an iPhone – or any other device – with pre-installed stalkerware. There are many companies that make these services available online, allowing abusers to have these tools installed on new phones, which can then be delivered in factory packaging under the guise of a gift to the intended victim.

Together keeping up the fight against stalkerware

Stalkerware is foremost not a technical problem, but an expression of a problem within society which therefore requires action from all areas of society. Kaspersky is not only actively committed to protecting users from this threat but also maintaining a multilevel dialogue with non-profit organizations, and industry, research and public agencies around the world to work together on solutions that tackle the issue.

In 2019, Kaspersky was the first cybersecurity company in the industry to develop a new attention-grabbing alert that clearly notifies users if stalkerware is found on their device. While Kaspersky’s solutions have been flagging potentially harmful apps that are not malware – including stalkerware – for many years, the new notification alerts the user to the fact that an app has been found on their device that may be able to spy on them.

In 2022, as part of Kaspersky’s launch of a new consumer product portfolio, the Privacy Alert was expanded and now not only informs the user about the presence of stalkerware on the device, but also warns the user that if stalkerware is removed the person who installed the app will be alerted. This may lead to an escalation of the situation. Moreover, the user risks erasing important data or evidence that could be used in a prosecution. Figure 2, below, shows the new warning in the blue box. Kaspersky’s Privacy Alert is included in all of the company’s consumer security solutions to protect against stalkerware.

In 2019, Kaspersky also co-founded the Coalition Against Stalkerware, an international working group against stalkerware and domestic violence that brings together private IT companies, NGOs, research institutions, and law enforcement agencies working to combat cyberstalking and help victims of online abuse. Through a consortium of more than 40 organizations, stakeholders can share expertise and work together to solve the problem of online violence. In addition, the Coalition’s website, which is available in 7 different languages, provides victims with help and guidance in case they may suspect stalkerware is present on their devices.

From 2021-2023, Kaspersky was a consortium partner of the EU project DeStalk, co-funded by the Rights, Equality, and Citizenship Program of the European Union. The five project partners that formed the consortium combined the expertise of the IT Security Community, Research, and Civil Society Organizations, and Public Authorities. As a result, the DeStalk project trained a total of 375 professionals directly working in women’s support services and perpetrator programs, and officials from public authorities on how to effectively tackle stalkerware and other digital forms of gender-based violence, as well as raising public awareness on digital violence and stalkerware.

As part of the project, Kaspersky developed an e-learning course on cyberviolence and stalkerware within its Kaspersky Automated Security Awareness Platform, a freely available online micro learning training platform which can be accessed in five different languages. To date, more than 130 professionals have completed the e-learning course with a further 80 currently participating. Although the DeStalk project has ended, the e-learning course is still available on the DeStalk project website.

In June 2022, Kaspersky launched a website dedicated to TinyCheck to disseminate further information about the tool. TinyCheck is a free, safe and open-source tool that can be used by non-profit organizations and police units to help support victims of digital stalking. In 2020, the tool was created to check devices for stalkerware and monitoring apps without making the perpetrator aware of the check. It does not require installation on a user’s device because it works independently to avoid detection by a stalker. TinyCheck scans a device’s outgoing traffic using a regular Wi-Fi connection and identifies interactions with known sources such as stalkerware-related servers. TinyCheck can also be used to check any device on any platform, including iOS, Android, or any other OS’.

Think you are a victim of stalkerware? Here are a few tips…

Whether or not you are a victim of stalkerware, here are a few tips to better protect yourself:

  • Protect your phone with a strong password that you never share with your partner, friends, or colleagues.
  • Change passwords for all of your accounts periodically and don’t share them with anyone.
  • Only download apps from official sources, such as Google Play or the Apple App Store.
  • Install a reliable IT security solution like Kaspersky for Android on devices and scan them regularly. However, in the case of potentially already installed stalkerware, this should only be done after the risk to the victim has been assessed, as the abuser may notice the use of a cybersecurity solution.

Victims of stalkerware may be victims of a larger cycle of abuse, including physical.

In some cases, the perpetrator is notified if their victim performs a device scan or removes a stalkerware app. If this happens, it can lead to an escalation of the situation and further aggression. This is why it is important to proceed with caution if you think you are being targeted by stalkerware.

  • Reach out to a local support organization: to find one close to you, check the Coalition Against Stalkerware website.
  • Keep an eye out for the following warning signs: these can include a fast-draining battery due to unknown or suspicious apps using up its charge, and newly installed applications with suspicious access to use and track your location, send or receive text messages and other personal activities. Also check if your “unknown sources” setting is enabled, it may be a sign that unwanted software has been installed from a third-party source. However, the above indicators are circumstantial and do not indicate the unequivocal presence of stalkerware on the device.
  • Do not try to erase the stalkerware, change any settings or tamper with your phone: this may alert your potential perpetrator and lead to an escalation of the situation. You also risk erasing important data or evidence that could be used in a prosecution.
