Android users are facing a serious cybersecurity risk as the infamous HOOK banking trojan has transformed into a more advanced and dangerous strain. Dubbed HOOK Version 3, the malware now merges capabilities of banking fraud, ransomware, and spyware—making it one of the most sophisticated mobile threats uncovered to date.

A New Breed of Hybrid Malware

Researchers at Zimperium’s zLabs have revealed that HOOK Version 3 introduces a massive expansion in functionality, supporting 107 remote commands—38 of which are newly added.

These enhancements give attackers unprecedented control over infected devices, enabling them to:

Launch full-screen ransomware overlays that demand cryptocurrency payments.
Execute fake NFC scans designed to trick victims into disclosing sensitive data.
Display deceptive unlock screens to capture PINs or pattern lock codes.
Record user gestures through transparent overlays, hijack sessions, and even stream the device’s screen in real time.

Ransomware, Phishing, and Surveillance Combined

With these capabilities, HOOK Version 3 is no longer limited to financial theft. It now operates as a multi-pronged threat that can:

Encrypt and ransom user data.
Trick victims into revealing personal details via phishing-style tactics.
Monitor, manipulate, and remotely control infected devices.

This evolution cements its role as one of the most dangerous mobile trojans currently in circulation.

From Phishing Sites to GitHub

Unlike earlier versions, the new HOOK variant is spreading through malicious APKs hosted on GitHub—a shift that undermines the platform’s legitimacy while making it easier to deceive unsuspecting users.

Security analysts have also noted its association with other trojans such as Ermac and Brokewell, pointing to a growing malware-as-a-service ecosystem.

While HOOK is circulating outside official app stores, Google confirmed that no infected apps have been detected on Google Play.

“Android users are automatically protected against known versions of this malware by Google Play Protect, which is on by default on Android devices with Google Play Services,” a Google spokesperson said. “Google Play Protect can warn users or block apps known to exhibit malicious behavior, even when those apps come from sources outside of Play.”

How to Protect Against HOOK Version 3

Cybersecurity experts recommend the following precautions to defend against HOOK Version 3 and similar mobile threats:

Download apps only from trusted sources like the Google Play Store.
Enable Google Play Protect to automatically scan for harmful apps.
Scrutinize app permissions, especially requests for accessibility service access.
Keep devices and apps updated to patch known security vulnerabilities.
Use reputable mobile security solutions capable of detecting and blocking advanced malware.

By maintaining strong security practices and exercising caution, Android users can lower their risk of falling victim to HOOK Version 3 and the growing wave of hybrid mobile malware.
