What’s up with cybercriminals’ obsession with signing customers up for subscriptions behind their backs? Final week, we dove into Microsoft 365 Protection Analysis Workforce’s report on toll fraud, which concerned malicious actors conspiring with telephone firms to maintain you at the hours of darkness about secret subscription signal ups.
Now, cybersecurity agency Evina found eight naughty apps that employed related ways. All contained a malware bug referred to as Autolycos, which enrolled customers for premium providers, and consequently, victims unwittingly misplaced cash regularly — and so they did not even notice it.
Autolycos is a vicious, stealthy Android bug
Maxime Ingrao, a safety researcher at Evina, found Autolycos in at the least eight Google Play Retailer apps in June 2021:
- Vlog Star Video Editor – 1 million downloads
- Coco Digicam v1.1 – 1,000 downloads
- Gif Emoji Keyboard – 100,000 downloads
- Wow Magnificence Digicam – 100,000 downloads
- Humorous Digicam – 500,000 downloads
- Razer Keyboard & Theme – 50,000
- Freeglow Digicam 1.0.0 – 5,000 downloads
- Artistic 3D Launcher – 1 million downloads
In whole, the eight apps have been downloaded three million instances. In line with Ingrao, malicious actors marketed their Autolycos-infested apps on social media. For instance, Fb featured 74 advert campaigns for the Razer Keyboard & Theme app.
So what’s Autolycos’ modus operandi? As talked about, it subscribes customers to premium providers — and victims are none the wiser. What’s worse is that Autolycos operates stealthily and sneakily, in accordance with Ingrao, so its malicious presence is not instantly obvious. To make its actions much less noticeable, it executes URL launches on a distant browser.
In some circumstances, the malware-infested apps requested permission to learn customers’ SMS content material, giving the malicious software program entry to victims’ textual content messages.
Google did not take away the apps till the report went public
Apparently, Ingrao informed BleepingComputer that he reported its discovery to Google in June 2021, however as a result of search-engine big’s delay in eradicating the eight malicious apps from the Play Retailer, Ingrao simply disclosed his findings to the general public on July 13.

Ingrao’s tweets should have lit a fireplace beneath Google’s butt. Six of the apps had been eliminated roughly six months after Ingrao first notified Google, however two remained when Ingrao tweeted about it this week. We tried to search out all eight apps on the Google Play Retailer, however happily, they’ve now all been eliminated.
If you happen to’re questioning how one can keep forward of those wallet-draining, malware-infested Android apps, preserve an eye fixed out for suspicious permission requests that do not make any sense. For instance, if a video modifying app asks for entry to your SMS messages, you ought to be cautious. Why the heck would an modifying app must see your texts?
