Google Removes 77 Android Apps With 19 Million Installs After Zscaler Malware Report

Researchers say the Anatsa trojan now targets 831 financial apps, highlighting how malicious code can pass Play Store review in disguised downloads.

Overview

  • Zscaler documented 77 malicious or adware-laden apps and reported them to Google, which pulled the listings and, according to reports, began removing them from enrolled devices via Play Protect.
  • Anatsa’s latest campaign expands targeting to 831 financial institutions, including new banks in Germany and South Korea as well as crypto platforms, and steals credentials via tailored fake login pages.
  • To evade detection, operators used droppers, runtime-loaded DEX payloads and malformed archives that conceal code until activation from command-and-control servers.
  • Other families surfaced in the takedown, with Joker present in at least a quarter of the apps, Harly posing as simple utilities, and adware components found in about two thirds of the identified titles.
  • Users who installed affected apps should uninstall them, run antivirus scans and review permissions such as Accessibility, and Computer Bild reports Google plans a developer identity requirement in 2026 to curb abuse.
