Android Banking Trojan Anatsa Expands Campaign to Slovakia, Slovenia, and Czechia
The notorious Android banking trojan, Anatsa, has recently expanded its operations to include Slovakia, Slovenia, and Czechia, according to cybersecurity experts. This move was observed as part of a new campaign that took place in November 2023.
Anatsa, also known as TeaBot and Toddler, is known for disguising itself as seemingly harmless apps on the Google Play Store. Despite enhanced detection and protection mechanisms implemented by Google Play, some of the droppers in this campaign were successful in exploiting the accessibility service, evading security measures imposed by Google.
In the most recent campaign observed in November 2023, one of the droppers masqueraded as a phone cleaner app named “Phone Cleaner – File Explorer.” This dropper utilized a technique called versioning to introduce its malicious behavior. Although the app is no longer available for download from the official Android storefront, it can still be obtained through unreliable third-party sources.
During its time on the Google Play Store between November 13 and November 27, the app was estimated to have been downloaded approximately 12,000 times according to app intelligence platform, AppBrain. The app appeared harmless upon release, but an update introduced malicious code a week later, allowing the trojan to execute malicious actions upon receiving a configuration from the server.
Cybersecurity experts highlight that these malicious actors prefer concentrated attacks on particular regions rather than a global spread. By periodically shifting their focus, they can target a limited number of financial organizations, resulting in a higher number of fraud cases within a shorter time frame.
Like many Android malware strains today, Anatsa abuses the accessibility API, emphasizing the need for enhanced security measures to protect users against these threats.
