Score
68/100

tzr-4fgge.iris42.workers.dev is a tenant hostname on Cloudflare, not a separately registered domain. PhishDestroy first observed the hostname on Aug 21, 2026. Stored content metadata identifies Trezor as the apparent target. The captured page title is “Trezor Suite”. Stored page analysis classifies the content as impersonation. Current evidence score: 68/100 (high).

Positive findings are stored from 2 sources: SEAL and URLScan. SEAL listed the hostname in the separate external-blocklist snapshot on Aug 21, 2026 at 10:20 UTC. URLScan returned a malicious verdict with score 100; scan metadata linked the capture to Trezor and assigned phishing as its category on Aug 21, 2026 at 11:08 UTC. Non-positive and contextual checks: VirusTotal recorded 0 detections among 91 engines on Aug 21, 2026 at 09:20 UTC. Google Safe Browsing returned no flag on Aug 21, 2026 at 09:56 UTC. The 0/91 VirusTotal snapshot and the positive findings above are conflicting observations from different sources or collection times.

The collector marked the hostname reachable on Aug 21, 2026 at 09:18 UTC, but did not retain the HTTP response code. Cloudflare is the hosting platform for this tenant, not its registrar. At collection time, the hostname resolved to 188.114.97.3 on AS13335 (Cloudflare, Inc.). The IP and ASN identify shared Cloudflare infrastructure, not the tenant operator. The evidence archive retains 2 visual captures from PhishDestroy and URLScan. The platform TLS certificate was issued by Google Trust Services with validity through Sep 28, 2026; checked Aug 21, 2026 at 10:02 UTC.

The content indicators and 2 positive source findings support the current Trezor-themed impersonation classification.
