Emerging Threats: Malicious Chrome Extensions Mimic Trusted Password Managers

Chrome extensions play a vital role in enhancing online functionality, whether for blocking ads or optimizing browsing experiences. While they can be downloaded from the Chrome Web Store, these tools are more vulnerable to imitation and conversion into harmful software compared to traditional applications.

Recently, a significant security incident affected more than 3.2 million users linked to mutinous browser extensions. This attack underscores how cybercriminals exploit seemingly legitimate tools to distribute malware or harvest sensitive information.

Security experts have identified a new polymorphic attack method that allows harmful Chrome extensions to disguise themselves as trusted services, including password managers and banking applications. This sophisticated approach facilitates the theft of sensitive user information.

The Nature of Polymorphic Attacks

Researchers from SquareX Labs have unveiled a dangerous capability of malicious Chrome extensions, allowing them to impersonate legitimate software to deceive users. Through this polymorphic technique, attackers exploit Chrome’s extension architecture, enabling them to conduct their activities discreetly.

The initial phase of the attack involves hackers submitting what appears to be a benign extension to the Chrome Web Store. This fake product may even possess legitimate features, such as an AI-powered marketing tool, to attract unsuspecting users into downloading and installing it.

How the Attack Progresses

Following installation, the malicious extension conducts a scan of the victim’s browser to identify other extensions. It employs one of two techniques: if granted access to the
