sifilis[.]today

The domain sifilis.today was registered on February 23, 2026 through NiceNIC International Group Co., Limited and is currently hosted behind Cloudflare (AS13335) with the IP address 188.114.97.3 located in the United States. The site serves over HTTP/3 and reports Cloudflare Browser Insights as a detected technology. TLS termination is provided by a Let's Encrypt certificate (E8). An HTTP 307 redirect is observed, and the page title returned is "SteamGuard Panel — Login," indicating a direct attempt to impersonate the Steam brand. The domain appears on three public security blocklists and is actively blocked by PhishDestroy, MetaMask, and SEAL.

VirusTotal scans show three of ninety‑three security vendors flagging the domain, reinforcing the suspicion of malicious activity. The Gridinsoft trust score is 0 out of 100, and the overall risk rating is high. Nameservers are melnicoff.ns.cloudflare.com and liberty.ns.cloudflare.com. The intelligence categorises the operation as a gaming‑scam, specifically brand impersonation targeting Steam users.

While the exact payload or credential‑harvesting mechanism has not been publicly disclosed, the combination of brand‑specific page title, low trust score, blocklist presence, and vendor detections strongly suggests a phishing infrastructure. Defenders should block the domain at perimeter firewalls, update URL filtering lists, and monitor for any outbound connections to the associated IP. Incident response teams should also examine logs for attempts to access sifilis.today and consider user‑education campaigns focused on SteamGuard authentication flows. Continued observation is required as the site remains active.
