trzr3545refdfgfdg[.]df87[.]workers[.]dev

Analysis of trzr3545refdfgfdg.df87.workers.dev shows a newly registered domain created on February 21, 2026 that is currently taken offline but was observed serving a page titled “Welcome to Suite”. The site resolves to the Cloudflare‑owned address 172.67.180.148, which is part of AS13335 in the United States. DNS delegation lists clyde.ns.cloudflare.com and sofia.ns.cloudflare.com, confirming the use of Cloudflare’s infrastructure. The TLS certificate is issued by Google Trust Services under the WE1 intermediate, indicating a valid HTTPS endpoint despite the malicious intent. HTTP response code 403 was returned at the time of observation, suggesting that the content may have been restricted or that the site is no longer serving the phishing payload.

Technical fingerprints show HTTP/3 support, enforced HSTS, and the presence of Cloudflare as a reverse proxy. Reputation scoring is extremely low, with Gridinsoft assigning a trust score of 0 out of 100. VirusTotal scans returned detections from 14 of 93 vendors, indicating that multiple antivirus engines flag the domain as malicious. The domain appears on a single public blocklist and is actively blocked by PhishDestroy. The site is classified as a wallet or seed phishing campaign and explicitly impersonates the brand “argent”.

Registration was performed through Cloudflare, Inc., which is consistent with the observed nameservers and IP hosting. While the site is presently offline, the infrastructure components—Cloudflare edge nodes, a valid Google‑issued certificate, and a low trust score—suggest that the operators can rapidly reactivate the domain or clone the setup elsewhere. Defenders should block the IP address 172.67.180.148 and any future resolutions of the domain, monitor for DNS changes to the same Cloudflare nameservers, and add the domain to internal blocklists.
