Four different Android banking trojans were spread via the official Google Play Store between August and November 2021, resulting in more than 300,000 infections through various dropper apps that posed as seemingly harmless utility apps to take full control of the infected devices.
Designed to deliver Anatsa (aka TeaBot), Alien, ERMAC, and Hydra, cybersecurity firm ThreatFabric said the malware campaigns are not only more refined, but also engineered to have a small malicious footprint, effectively ensuring that the payloads are installed only on smartphones devices from specific regions and preventing the malware from being downloaded during the publishing process.
