Hirudo Android Trojan Uses Patched Banking Apps to Bypass Their Built-In Security Checks

ThreatFabric disclosed Hirudo, a new Android banking trojan that replaces legitimate banking apps with patched versions to bypass in-app security checks. The Dutch firm identified replacements for eight Indonesian banking apps, marking an escalation in financial fraud. The trojan operates from inside the app itself, evading the built-in protections of the original applications.
