The domain w-challenge.com was created on September 18, 2018 and is currently taken offline. It resolves to the IPv4 address 154.219.125.4, which is assigned to FASTNET DATA INC (AS8796) in the United States. The domain is registered through NameCheap, Inc. and uses the shared DNS pair a.share-dns.com, a1.share-dns.com, b.share-dns.net, and b1.share-dns.net. No SSL certificate is observed for the site, and the HTTP service is not responding, confirming the offline status.

VirusTotal analysis shows that ten of ninety‑five security vendors have flagged the domain, indicating a consensus of malicious intent. Independent scoring from Gridinsoft assigns a trust score of 0 out of 100, reinforcing the low reputation. The domain appears on a single security blocklist and is actively blocked by PhishDestroy. The only page metadata available is the title "w-challenge.com," which matches the domain name but provides no additional context.

No Safe Browsing, OTX, or additional vendor‑specific reports are present in the current intelligence set. From the evidence, the infrastructure appears to have been used for generic phishing campaigns, though the exact target or content has not been captured. Defenders should add w-challenge.com and its resolving IP 154.219.125.4 to network blocklists, monitor the associated name servers for potential re‑use, and maintain vigilance for any future reactivation of the domain. Updating intrusion detection signatures with the observed DNS pattern and host attribution will help mitigate re‑emergent threats from this infrastructure.
