The attack cannot be mitigated by simply patching the browser, as it exploits legitimate Chrome functionalities. The risk primarily lies in the initial installation of the malicious extension and a single deceptive click by the user. This vulnerability underscores the danger of relying on visual cues for security confirmation and highlights the need for a significant overhaul to prevent such attacks. SquareX has disclosed the issue to Google, emphasizing the widespread reliance on browser-based password managers and crypto wallets, which could be compromised by this method.
Key takeaways:
- A new vulnerability in Google Chrome and other Chromium browsers allows malicious extensions to impersonate legitimate ones, risking sensitive data like passwords and crypto wallets.
- The attack involves tricking users into installing a benign-looking extension that later mimics sensitive apps to steal credentials.
- The attack exploits legitimate Chrome functionality, making it difficult to patch, and relies on users' visual cues for deception.
- This vulnerability is not limited to Chrome and can also affect other Chromium-based browsers, posing a widespread risk.
