🚨SlowMist @SlowMist_Team: Crypto users need to be wary of browser extensions being sold to malicious actors and redirected to phishing sites, with no alerts and no warnings!

This means that as long as re-authorization is not required, the entire process of being redirected to a scam site may go unnoticed.

Some extensions can also be replaced by hackers via API to change the deposit and withdrawal addresses of CEX users;

Therefore, it is recommended to periodically inspect these extensions and adopt a layered defense strategy—

1⃣ Proactive defense before installation

  1. Only download extensions from official stores, and pay special attention to Google's official risk labeling and authorization.

  2. Only keep a few essential extensions; some extensions may have been installed as part of a bundle, so clean them up in a timely manner.

  3. Conduct a thorough review of extension qualifications, prioritizing developers from companies rather than anonymous accounts.

  4. Be cautious of extensions that suddenly start updating frequently after a long period of inactivity.

2⃣ Permission control during installation

  1. Follow the principle of least privilege, refusing excessive permissions, such as a notepad-type extension requesting "read all website data," and use Chrome's "Site Access" feature to limit the scope of the extension.

  2. It is best to sandbox the operating environment. For example, you can isolate high-risk extensions using Firefox Multi-Account Containers or create dedicated browser profiles using Chrome Profiles.

3⃣ Dynamic monitoring during use

  1. If possible, combine third-party tools for network traffic monitoring, such as Wireshark for packet analysis/GlassWire for traffic visualization.

  2. Enable extension security monitoring tools: CrxMouse Monitor/Extension Defender.

  3. Regularly run browser security checks: chrome://extensions/?id=cfhdojbkjhnklbpkdaibdccddilifddb.

On-chain security is no small matter; safety is always the top priority!
