A number of rogue Android apps that have been cumulatively installed from the official Google Play Store more than 50,000 times are being used to target banks and other financial entities. Like other Android banking trojans, the rogue apps are nothing more than droppers, whose primary function is to deploy the malicious payload embedded within them.
As many as seven malicious Android apps discovered on the Google Play Store masqueraded as antivirus solutions to deploy a banking trojan called SharkBot. "SharkBot steals credentials and banking information," Check Point researchers Alex Shamshur and Raman Ladutska said in a report shared with The Hacker News.
A malicious Android app that steals Facebook credentials has been installed over 100,000 times via the Google Play Store, with the app still available to download. The Android malware is disguised as a cartoonifier app called 'Craftsart Cartoon Photo Tools,' allowing users to upload an image and convert it into a cartoon rendering. Over the past week, security researchers and mobile security firm Pradeo discovered that the Android app includes a trojan called 'FaceStealer,' which displays a Facebook login screen that requires users to log in before using the app.
The trojanized Craftsart Cartoon Photo Tools app is available in the official Android app store, but it's actually spyware capable of stealing any and all information from victims' social-media accounts. A popular mobile app in the official Google Play store called "Craftsart Cartoon Photo Tools" has racked up more than 100,000 installs - but unfortunately for the app's enthusiasts, it contains a version of the Facestealer Android malware.
Security researchers tracking the mobile app ecosystem have noticed a recent spike in trojan infiltration on the Google Play Store, with one of the apps having over 500,000 installs and available to download. Most of these apps belong to a family of trojan malware used in various scams, resulting in financial losses and also loss of sensitive personal information. The threats discovered on the Play Store by Dr. Web's analysts include cryptocurrency management apps, social benefit aid tools, Gasprom investment clones, photo editors, and a launcher themed after iOS 15.
The threat actor behind a nascent Android banking trojan named SharkBot has managed to evade Google Play Store security barriers by masquerading as an antivirus app. Where SharkBot stands apart is in its ability to carry out the unauthorized transactions via Automatic Transfer Systems, which stands in contrast to TeaBot, which requires a live operator to interact with the infected devices to conduct the malicious activities.
An Android banking trojan designed to steal credentials and SMS messages has been observed sneaking past Google Play Store protections to target users of more than 400 banking and financial apps from Russia, China, and the U.S. "TeaBot RAT capabilities are achieved via the device screen's live streaming plus the abuse of Accessibility Services for remote interaction and key-logging," Cleafy researchers said in a report. Also known by the name Anatsa, TeaBot first emerged in May 2021, camouflaging its malicious functions by posing as seemingly innocuous PDF document and QR code scanner apps that are distributed via the official Google Play Store instead of third-party apps stores or via fraudulent websites.
SharkBot banking malware has infiltrated the Google Play Store, the official Android app repository, posing as an antivirus with system cleaning capabilities. SharkBot was discovered in Google Play by researchers at the NCC Group, who today published a detailed technical analysis of the malware.
The TeaBot banking trojan - also known as "Anatsa" - has been spotted on the Google Play store, researchers from Cleafy have discovered. Hank Schless, senior manager of security solutions at Lookout, explained via email that attackers "Usually stick to utility apps like QR code scanners, flashlights, photo filters, or PDF scanners because these are apps that people download out of necessity and likely won't put as much time into looking at reviews that might impact their decision to download.".
The TeaBot banking trojan was spotted once again in Google Play Store where it posed as a QR code app and spread to more than 10,000 devices. The trojanized apps include the promised functionality, so user reviews on the Play Store are positive.
