The Anatsa banking trojan has intensified its assault on Android users across Europe, leveraging malware droppers strategically hosted on Google Play.

Security experts at ThreatFabric have observed a surge in Anatsa-related incidents over the past four months, with a staggering 150,000 infections detected.

Sophisticated Attack Strategies

Anatsa orchestrates its attacks through meticulously crafted dropper apps, meticulously designed to infiltrate the "Top New Free" categories on Google Play, thus bolstering their credibility and efficacy. These dropper apps employ a multi-staged infection process, leveraging Android's Accessibility Service to circumvent security barriers.

Evolution of Dropper Apps

Google's Response

While Google has swiftly removed most Anatsa dropper apps from its platform, the threat persists, with some apps still accessible to users. ThreatFabric estimates the actual number of downloads to be closer to 200,000, emphasizing the scale of the threat.

Continued Threat and Expansion

Despite efforts to mitigate the Anatsa menace, the trojan persists in launching fresh attack waves, constantly introducing new dropper apps to ensnare more victims. The total number of downloads is projected to surge further, surpassing previous milestones, Bleeping Computer reports.
