9642156265?profile=RESIZE_400xAn Android Trojan has now achieved a victim count of over 10 million in at least 70 countries.  Researchers say the infections are generating millions of dollars a month in recurring revenue.  According to Zimperium zLabs, the new malware has been embedded in at least 200 malicious applications, many of which have managed to circumvent the protections offered by the Google Play Store, the official repository for Android apps.

The researchers say that the operators behind the Trojan have managed to infect so many devices that a stable cash flow of illicit funds, "generating millions in recurring revenue each month," has been established.  Believed to have been in operation since November 2020, the "GriftHorse" campaign relies on victims being duped into handing over their phone number, which is then used to subscribe them to premium SMS messaging services.

Victims first download Android apps that appear innocent and legitimate.  These apps vary from puzzle games and utilities to dating software, food, and drink, with the most popular malicious app a translator accounting for at least 500,000 downloads.

Upon installation, however, the GriftHorse Trojan, written in Apache Cordova, constantly bombards the user with messages, alerting them to a fake prize they have won and then redirecting them to a website page based on their geolocation, and, therefore, their language.  This scam is being used by threat actors pretending to be from the AT&T wireless billing department. The text offers you a “Free gift” for paying your monthly bill.  Since the app is driven by country, the message refers to you as Robert, Charles, James, etc., common North American names.

Mobile users are then asked to submit their phone numbers for verification purposes. If they submit this information, they are then subscribed to premium services "without their knowledge and consent," zLabs noted.

Some of the charges are upward of €30 ($35) per month, and if a victim does not notice this suspicious transaction, then they could, theoretically, be charged for months on end with little hope of ever clawing back their cash.

To avoid discovery, the malware's operators use changeable URLs rather than hardcoded addresses.  "This method allowed the attackers to target different countries in different ways," the team says. "This check on the server-side evades dynamic analysis checking for network communication and behaviors."

zLabs reported its findings to Google who promptly removed the Android apps marked as malicious from Google Play. However, these apps are still available on third-party platforms.
