Fake WhatsApp Spyware App Targets Hundreds of Users

WhatsApp has warned around 200 users that they may have been targeted by a fake version of its app designed to secretly install spyware. The company says most of the affected users are based in Italy and were tricked into downloading an unofficial iOS client.

According to WhatsApp, the malicious app was allegedly created by Italian spyware firm SIO. Once installed, the fake app could compromise users’ privacy, potentially allowing surveillance through hidden software embedded inside it.

Users Alerted and Logged Out

WhatsApp says its security team identified the issue early and took action to protect affected accounts. Around 200 users were notified, logged out of the fake app, and advised to remove it immediately.

The company also urged users to only download apps from official sources, highlighting the risks of installing unofficial versions. “Our priority has been protecting the users who may have been tricked,” said WhatsApp spokesperson Margarita Franklin.

At this stage, WhatsApp has not disclosed who the targeted users were. It remains unclear whether journalists, activists, or other members of civil society were among those affected.

Legal Action on the Way

WhatsApp is now planning to take legal steps against SIO, stating it will issue a formal demand to stop what it describes as malicious activity. The company’s move signals growing tension between tech platforms and surveillance firms over the misuse of apps for spying.

Reports from La Repubblica and ANSA first brought the issue to light.

A Known Spyware Strategy

This isn’t the first time SIO has been linked to spyware campaigns. Previous investigations revealed the company developed malicious Android apps, including fake WhatsApp versions and bogus customer support tools.

The spyware used in those campaigns was identified as “Spyrtacus,” a name found in its code. These apps were often distributed through phishing links, sometimes sent with the help of telecom providers as part of surveillance operations.

SIO operates its spyware business through a subsidiary called ASIGINT, which focuses on government surveillance tools.

Part of a Bigger Pattern

Using fake apps to target individuals is a well-known tactic in surveillance efforts, particularly in Italy. Authorities have reportedly used such methods to monitor targets, often with assistance from mobile service providers.

This latest case follows a similar incident last year, when WhatsApp alerted about 90 users who were targeted with spyware from Paragon Solutions. Those attacks reportedly affected journalists and pro-immigration activists, sparking widespread controversy.

Following the backlash, Paragon cut ties with Italian intelligence agencies that had been using its technology.

Growing Concerns Over Spyware

The new warning highlights ongoing concerns about the spread of government-grade spyware and its potential misuse. As these tools become more sophisticated, tech companies like WhatsApp are stepping up efforts to detect threats and notify users.

For everyday users, the message is clear: stick to official app stores and be cautious of any app that doesn’t come from a trusted source.
