这个工具能够拦截web3上仿冒的诈骗网站，帮我避免了一次重大损失，真心非常感谢。优酷上有诈骗犯录制了声称质押代币获利的假冒的sushi网站，我不小心打开了。辛亏几分钟后，scam sniffer拦截页面出现，我被吓出了一身冷汗。这真是个好工具，人人都值得安装。工具的官方功德无量。非常感谢。

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Scam Sniffer requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.
