up-v4-verification[.]app

The domain up-v4-verification.app was registered on February 24, 2026 through PDR Ltd. d/b/a PublicDomainRegistry.com and resolves to the Cloudflare address 172.67.192.40, which is associated with ASN 13335 in the United States. The TLS certificate associated with the site carries an E8 rating, indicating a low security posture. Gridinsoft assigns the domain a trust score of 0 out of 100, and the page title returned by the HTTP endpoint is "Access Denied", suggesting that the site is no longer serving the malicious payload and has been taken offline.

VirusTotal reports that one of ninety‑three scanning engines flagged the domain, and three independent blocklists—PhishDestroy, MetaMask, and SEAL—have listed it as malicious. The domain appears on three additional security blocklists, reinforcing the consensus that it is being used for malicious purposes. The limited detection signal, combined with the low trust score and the presence on multiple blocklists, points to a phishing‑related campaign, although the exact target or payload has not been publicly disclosed.

Defenders should continue to block resolution of 172.67.192.40 at the network perimeter, ensure that any endpoints that previously accessed the domain are scanned for residual artifacts, and monitor for future registrations that reuse the same registrar or hosting provider. Because the site is currently offline, real‑time observation is not possible, and further intelligence should be gathered from any endpoint telemetry that captured the domain while it was active.
