简介
The Netcraft Extension is a tool allowing easy lookup of information relating to the sites you visit and providing protection from phishing and malicious JavaScript.
Key Features:
• Protection against phishing sites — The Netcraft anti-phishing community is effectively a giant neighbourhood watch scheme, empowering the most alert and most expert members to defend everyone within the community. As soon as the first recipients of a phishing mail report it, we can block it for all users of the extension providing an additional level of protection from Phishing. Netcraft processes reports of fraudulent URLs from a diverse variety of sources and proactively searches for new fraudulent sites.
• Protection against malicious JavaScript — Prevent your credit card details from being stolen by shopping site skimmers or your computer's processing power being harvested by web miners. Netcraft has been detecting shopping site skimmers, web miners, and other malicious JavaScript since 2017. The extension blocks sites that we have found to be compromised with malicious JavaScript. Additionally, it detects JavaScript that we have identified as being malicious, blocks pages that use it from loading, and automatically reports them to Netcraft to protect the rest of the community.
• Credential leak detection – Even if you come across a shopping site skimmer that Netcraft has not yet detected, the extension can still work to protect your card details. Credential leak detection inspects outgoing requests on the fly, blocking them if they carry your sensitive data to potentially malicious external domains. The compromised site is then blocked and reported to Netcraft.
• Detailed site reports – simply click the Netcraft logo to access a wealth of information about the sites you visit, helping you to make informed choices about their safety.
• Conveniently report suspected phishing & fraudulent sites – At the click of the button you can report suspected web forgeries to Netcraft, helping to protect the community. Netcraft operates an incentive scheme for Phishing site submissions, including iPads, backpacks, mugs, and more… https://report.netcraft.com/pages/report-incentives
