update-concrete[.]com

The domain update-concrete.com was registered on February 21, 2026 through Global Domain Group LLC and is currently offline. Infrastructure analysis shows the domain resolved to IP address 198.251.84.200, hosted by FranTech Solutions (ASN 53667) in the United States. Authoritative name servers are ns5.asurahosting.com and ns6.asurahosting.com, both consistent with the hosting provider. The site employed a Let's Encrypt certificate (R13) and leveraged LiteSpeed web server, Cloudflare CDN, HTTP/3, and third‑party libraries such as jsDelivr, crypto‑js, and cdnjs, indicating a modern web stack.

The page title returned by the server was “Resolve Panel,” which aligns with the credential‑phishing classification noted in the intelligence. VirusTotal scans recorded 2 detections out of 95 security vendors, and Gridinsoft assigned a trust score of 0 / 100, reflecting high malicious confidence. The domain appears on two public blocklists, specifically PhishDestroy and ScamSniffer, and has been flagged by those services as a credential‑phishing site. No additional threat‑intel sources (OTX, Safe Browsing) were cited in the available data.

The evidence points to a short‑lived phishing operation that likely harvested login credentials before being taken down. Uncertainty remains regarding the exact target brand or the phishing kit used, as the page content has not been publicly disclosed. Defenders should continue to block the domain at perimeter and DNS filters, monitor the associated IP range for any resurgence, and consider sharing the indicator set with threat‑sharing communities to improve early detection of similar infrastructure.
