Threats Tagged 'hook'

ERMAC and HookBot are two branches of one Android banking trojan sold as a service, forking from shared code originating with Cerberus. A copy of the builder, Laravel backend, and React panel leaked in August 2025, enabling unrelated operators to deploy panels with default credentials and keys still in place. The lineage runs Cerberus to ERMAC to Hook, confirmed through source code analysis showing identical database migrations and network protocol structures. HookBot added VNC remote control and 38 new commands while maintaining ERMAC's core. The leaked source includes a Docker stack, Obfuscapk builder, and IP-whitelist firewall that hides panels but leaves the builder port exposed. Operators target 484 apps across 40+ countries including Japanese banks, Brazilian financial institutions, Turkish banks, and cryptocurrency wallets. Detection artifacts survive in builder obfuscator flags and favicons, while panel titles remain easily changed.
