Twitter users have recently fallen victim to a significant loss of over $1 million due to the hijacking of browser cookies by the Aggr plugin installed on the Chrome browser. This incident highlights the importance of browser plugin security and the need for users to take proactive measures to protect themselves from these types of attacks.

Browser plugins, or extensions, are essentially tools that users delegate to handle a portion of web page information. However, they can also access and modify original web page information, obtain location, read/modify clipboard, read cookies/history, take screenshots, and record keystrokes. This means that these plugins can not only obtain information like cookies but also directly determine what web pages we see.

The GoPlus security team advises users to enhance their security awareness and use browser plugins safely by following these methods. First, users should avoid using plugins of unknown origin and only download plugins from the official market. Even official plugins may be tampered with by hackers, so users should control access permissions and not grant unnecessary permissions.

Second, users should isolate the plugin browser and the transaction fund browser to prevent unauthorized access. Third, users should avoid logging in to the exchange via the web page and use incognito browsing for sensitive operations. Finally, users should regularly clear browser cache and cookies to prevent malicious extensions from obtaining cookies.

In conclusion, the hijacking of browser cookies by the Aggr plugin highlights the importance of browser plugin security and the need for users to take proactive measures to protect themselves from these types of attacks. By following the advice of the GoPlus security team, users can effectively prevent malicious extensions from obtaining cookies and protect their online security.
