sniffer-extension[.]info

The domain sniffer-extension.info was registered on February 21, 2026 through Unstoppable Domains Inc. and is currently offline. DNS resolution points to the IPv4 address 147.45.177.55, which is announced by AS215540 (GLOBAL CONNECTIVITY SOLUTIONS LLP) and geolocated to Canada. The domain uses Cloudflare authoritative nameservers harlee.ns.cloudflare.com and sonny.ns.cloudflare.com, but no TLS certificate is presented, indicating an unencrypted HTTP service. The only visible page title retrieved from the site is “Web3 Anti-Scam | Download”, which aligns with the reported scam type of a crypto‑related scheme targeting the brand Celer. The site has been classified as a brand‑impersonation crypto scam, and the Gridinsoft trust score of 0/100 reflects a highly malicious rating.

Four of ninety‑three security vendors on VirusTotal flagged the domain as malicious, and the domain appears on three external blocklists. It is actively blocked by PhishDestroy, MetaMask, and SEAL, demonstrating that multiple anti‑phishing and wallet protection services have identified it as hazardous. AlienVault OTX lists the domain in one threat‑intel pulse, providing additional corroboration of its malicious use. No SSL, no further page content, and the offline status limit real‑time observation; the exact phishing kit or page layout cannot be confirmed.

Defenders should add the domain and its IP address to deny‑list rules in firewalls, DNS filtering, and endpoint security solutions. Monitoring of the associated IP range (AS215540) for new domains that resolve to the same host is advised. Because the domain leverages the Unstoppable Domains registrar, organizations may consider tightening controls on .crypto and related naming services. Users of Celer‑related applications should be warned that any request to download a “Web3 Anti‑Scam” tool from this domain is fraudulent.
