ThreatSlayer (HiveFury)

HiveFury, formerly known as ThreatSlayer, is a browser security extension built to catch the threats that ordinary users run into most: scam sites, phishing pages and crypto wallet drainers. It checks each page you open against a threat list, and if the site is listed, replaces the tab with a clear warning that explains why. You can always go back or continue anyway, and your choice for that site is remembered locally.

Beyond site blocking, the extension adds a layer aimed at AI-era risks. An optional, off-by-default check runs on your device and stops API keys, private key files, card numbers and Social Security numbers from being pasted into AI chat assistants. There is also a dedicated wallet check that warns when a page asking to connect your crypto wallet is listed as a drainer.

The privacy stance is deliberately minimal: no account, no sign-in, only the site address is sent for a check, pasted text is never uploaded, and usage statistics are optional. The free extension is the core product, with an optional paid HiveFury Advanced tier sold separately. HiveFury is meant to complement Chrome's built-in Safe Browsing, not replace it, and it does not scan images, PDFs, Office files, email addresses or phone numbers.
