It hosts a page titled “S4W – Short Link Generator – S4W” and returns HTTP 200 over TLS with a Let’s Encrypt certificate. The site runs on a Plesk‑managed PHP stack, uses Bootstrap for the front‑end, and incorporates Cloudflare services including Browser Insights and HTTP/3.

The authoritative nameservers are chip.ns.cloudflare.com and deb.ns.cloudflare.com, confirming full Cloudflare proxying. The site embeds Google Analytics and Clipboard.js, indicating typical link‑shortening functionality that can be abused to relay malicious URLs.

Threat intelligence records note that s4w.in has been blocked by PhishDestroy and appears on one public blocklist. VirusTotal scans have flagged the domain by eight of ninety‑five antivirus engines, and the Gridinsoft trust score is 0 / 100, reinforcing the high confidence of malicious intent. The domain was registered on 15 Nov 2007 via GoDaddy, suggesting a long‑standing infrastructure that may have been repurposed.

Defenders should treat any traffic to s4w.in as hostile. Immediate actions include adding the domain and its resolving IP to outbound filtering rules, updating DNS blocklists, and monitoring for short‑link usage that redirects to credential‑harvesting pages. Continuous observation of Cloudflare edge logs for anomalous request patterns is advised, and any detected redirects should be investigated for credential theft or malware distribution.
