HookBot originated as a fork of the Ermac malware family, a well-known Android Trojan. The threat actor "DukeEugene" is credited with developing both Ermac and HookBot, leveraging their codebases to add advanced functionalities. HookBot Fork further builds on these foundations, introducing features that enable more comprehensive remote access and sophisticated data theft techniques, posing a heightened risk to users.

Distribution and Builder Tools

The widespread use of HookBot Fork has been facilitated by builder tools, allowing attackers to easily customize malware variants for specific campaigns. These tools are often sold on underground forums or shared through platforms like Telegram, enabling even less experienced attackers to deploy malicious applications. The malware is typically distributed via phishing campaigns or bundled within apps masquerading as legitimate tools from trusted brands.

Capabilities and Impact

HookBot Fork employs overlay attacks to deceive users, presenting fake login screens that mimic popular banking and cryptocurrency apps. It captures user credentials, intercepts SMS-based two-factor authentication codes, and can even automate malicious actions using Android accessibility permissions. Additionally, the malware's worm-like behavior enables it to propagate via messaging apps such as WhatsApp, further expanding its reach.
