In October, Certo Software announced that it has joined forces with the Coalition Against Stalkerware to combat non-consensual tracking via digital devices, and to work towards providing support to the survivors of the domestic violence.

Today, the UN’s International Day for the Elimination of Violence Against Women also coincides closely with the Coalition Against Stalkerware’s one year anniversary. In its first year, the Coalition has more than doubled its membership, expanding both in geography and expertise in its partners including domestic violence advocacy and direct service organizations, IT security vendors, mobile security companies, privacy solutions providers, an association of technology journalists, and organizations focused on cyber safety.

For some years, the problem of stalkerware has been on the rise. Non-profit organizations are experiencing a growing number of survivors seeking help with the problem, and cybersecurity companies are detecting a consistent increase in these harmful applications. Launched in November 2019, the Coalition Against Stalkerware became an important organization dedicated to protecting consumers from abuse, stalking and harassment via commercially-available surveillance software.

What is Stalkerware?

Stalkerware programs enable an abuser to intrude into a person’s private life and can be used as a tool for abuse in cases of domestic violence and stalking. By installing these applications on a person’s device, abusers can get access to their victim’s messages, photos, social media, geolocation, audio or camera recordings (in some cases, this can be done in real-time). Such programs run hidden in the background, without a victim’s knowledge or consent.

Data from member organizations has shown a sharp rise in stalkerware apps in recent years.

  • In 2019, Kaspersky detected a 67% year-on-year increase of stalkerware usage on its users’ mobile devices at a global level. The number of stalkerware installations worldwide during the first 10 months of 2020 (from January to October) totaled more than 48,500, which is close to the total (almost 52,000 installations) observed over the same period in 2019.
  • According to Malwarebytes, while these apps have always presented a significant threat to users, the shelter-in-place orders that began taking effect in March 2020 resulted in a dramatic uptick in usage. Malwarebytes recorded a peak increase from January 1 to June 30, finding a 780 percent increase in monitor apps detections, and a 1,677 percent increase in spyware detections. Though detections waned starting in July, the numbers never dropped to their January levels. From January 1 to October 31, Malwarebytes recorded a 584 percent increase in monitor app detections, and a 1,044 percent increase in spyware detections. Overall, this represents more than 43,000 monitor app detections in the first 10 months of 2020.
  • With Covid-19 spreading early 2020 and more and more countries going into lock-down to combat the pandemic F-Secure saw a significant increase in Stalkerware detections starting in March. While detections declined during early summer they shot up again towards the end of the holiday period and we noticed almost four times as many Stalkerware detections during August and September compared to the previous months. Cerberus is the most detected Stalkerware with 52 percent of the detections across unique mobile devices. Advertised as an anti-theft app it allows a stalker to hide on an Android device, prevent its deletion and also tracks the location of the device, takes pictures and screenshots as well as records audio.
  • Additionally, a recent UK survey run by us at Certo Software shows that only 31% of people surveyed thought that spying on someone else’s phone was illegal.

With lockdowns which may be globally repeated due to the second wave of the COVID-19 pandemic, domestic violence incidents may be increasing again. Coalition partners from different territories reported increases in Spring 2020.

  • In France, the Centre Hubertine Auclert explains there was a 50 % increase of calls to the main helpline for domestic violence victims (helpline 3919 of the Fédération Nationale Solidarité Femmes).
  • For India, the Cyber Peace Foundation refers to the National Commission for Women (NCW) reporting 587 complaints on their helpline number and online portal since the lockdown kicked into effect in March. Also, Cyber Peace Foundation states that 89% of the total number of cases registered to legal services authorities across the country were of domestic violence.
  • Findings of the Second National Survey on technology abuse and domestic violence in Australia launched by WESNET with the assistance of Dr Delanie Woodlock and researchers from Curtin University, are that 99.3% of DV practitioners have clients experiencing technology-facilitated abuse and that the use of video cameras increased by 183.2% between 2015 and 2000.

About the Coalition

The Coalition seeks to combine its partners’ expertise in domestic violence survivor support, digital rights advocacy, and cybersecurity to address the criminal behavior perpetrated by stalkerware and to raise general awareness about this important issue. European Institute for Gender Equality research shows that seven in ten women (70%) who have experienced cyber stalking, have also experienced at least one form of physical or/and sexual violence from an intimate partner.

Echoing words of the UN Secretary-General António Guterres who called gender violence ‘Shadow Pandemic’, members of the Coalition believe that we all have a role to play in recognizing the stealthy nature of stalkerware, the harmful impact that it has, and the need for collective action to support and assist individuals targeted by stalkerware.

During 2020, the Coalition partners have focused on raising greater awareness of stalkerware advocacy organizations, journalists, and regulators through public speeches, events, publications, research, and collecting the cybersecurity vendors’ data on stalkerware. The Coalition have also created a standard definition and detection criteria for stalkerware, which did not previously exist.

The Coalition’s plans for its second year include: outreach to individuals and organizations that can contribute to the stalkerware sample/metadata information sharing mechanism; additional data collection to inform evidence-based policymaking to respond to threats posed by stalkerware; series of assistance seminars to assist support organizations working with survivors of domestic violence and other individuals targeted by stalkerware; and further expansion of the Coalition to include additional organizations globally to assist in the mission of combating stalkerware and protecting individuals.

To find more about the organization’s activity, please visit the Coalition’s online resource. Users can find information about what stalkerware is, what it can do, how to detect it, and how to protect themselves in English, German, French, Italian, Spanish and Portuguese. For potentially affected users, the Coalition members recommend contacting local victim service organizations immediately.

Coalition member quotes

“The National Network to End Domestic Violence (NNEDV) is thrilled to partner with the Coalition Against Stalkerware. Through the work of our Safety Net Project, we know that many victims of domestic violence experience harassment, monitoring, stalking, and fraud from partners who use stalkerware as a tool of abuse, which can have lasting impacts on survivors’ safety and security. As a founding member of the Coalition, we reaffirm our commitment to understanding and addressing this tactic of abuse and ensuring that everyone, including survivors, can use technology without fear of violence.” – Deborah J. Vagins, NNEDV President and CEO

“We are extremely proud to be part of the Coalition Against Stalkerware, and to see the results after one year of existence. The topic of stalkerware is now emerging, and fruitful discussions among private and public partners in the Coalition are allowing to better protect victims of domestic violence. We invite you to join our online event around the topic in French on December 10.” – Iman Karzabi, Project Manager for the Regional Observatory of Violence Against Women at Centre Hubertine Auclert

“The effects of cyber violence on women and girls are devastating, all-consuming and never ending, because they are part of a continuum of violence (offline and online) that deprives them of their freedom.” – Alessandra Pauncz, WWP EN Executive Director

“Over the last year, we have made significant strides in educating the public about the growing dangers of stalkerware thanks to the incredible efforts of our partners,” said David Ruiz, Online Privacy Advocate at Malwarebytes. “Sharing information and working together is critical to ensuring that we help reduce the dangers of apps that can be used to track people without their knowledge or consent. We hope more organizations join us as we continue to fight to ensure users can choose how and when to share their data with others.”

“This is the first anniversary of the Coalition Against Stalkerware, and it has been quite a year in which we have learnt a lot. We now understand that stalkerware is not purely a technical problem. It’s not the IT part of the issue that is challenging, but the fact that we need to deal with the commercial availability of stalkerware, the lack of regulation around how it is being used and, perhaps the most difficult problem, the fact that violence against women and different forms of online abuse have been normalized. We can provide technical training on different forms of tech-enabled abuse for the NPOs, but it’s not enough – it should be complemented with a chapter focusing on and reflecting survivors’ psychological experiences,” comments Kristina Shingareva, Head of External Relations at Kaspersky.

“As a security vendor we’re acting on problems that severely affect people’s lives. Being able to support the Coalition we really feel like we’re able to make a difference.” – Matt Body, CTO of Traced

“The increasing prevalence of stalkerware in the environment should be a concern to everyone. These technologies can have frightening power over our lives that no person should ever wield.” – James Donaldson, CEO of Copperhead

“The member organizations in the Coalition Against Stalkerware have made tremendous strides in the last year, including awareness-raising, detection of stalkerware, and research into the daily lives of survivors of domestic abuse. The coalition has enabled us to take a holistic approach to a complex problem. There is no simple solution and we must keep pushing forward on many fronts.” – Eva Galperin, Director of Cybersecurity, Electronic Frontier Foundation
