estsensors[.]com

The domain estsensors.com was registered on 22 June 2025 through Key-Systems GmbH. It resolves to the IPv4 address 118.107.33.226, which is announced by AS152194 (CTG Server Limited) and geolocated to Hong Kong. No SSL certificate is present on the host, and the site is currently taken offline. PhishDestroy has listed the domain as blocked, and it appears on a single public security blocklist.

VirusTotal reports that 16 of 95 scanning engines flagged the domain as malicious. AlienVault OTX includes the domain in 16 distinct threat‑intel pulses. Independent reputation services assign extremely low scores: Gridinsoft rates it 0/100 and Scamadviser 1/100. The registrar information, IP attribution, and the multiple vendor detections collectively indicate that the domain was used for a generic phishing campaign targeting credential collection.

The exact phishing page content, page title, and targeted brand have not been released publicly, so the specific lure remains uncertain. Defenders should continue to block the domain and its associated IP address at perimeter and DNS layers, add it to internal blacklists, and monitor for any re‑use of the same registrar or hosting provider. Ongoing observation of the AS152194 network for similar activity is recommended, as well as periodic re‑scanning of the domain should it become active again.
