euler[.]airdropsalert[.]icu

On July 23, 2026, euler.airdropsalert.icu was identified as a high‑risk brand‑impersonation site targeting Google users with a fake airdrop lure. The domain was registered on 17 October 2025 through Dynadot LLC and is delegated to Cloudflare name servers brenna.ns.cloudflare.com and hassan.ns.cloudflare.com. DNS resolution points to 192.178.155.99, an address announced by AS15169 (Google LLC) and geolocated in the United States. No TLS certificate was presented, and the HTTP service is currently offline after being taken down; the site was previously blocked by the PhishDestroy sinkhole.

The page title returned by the live host was “Google”, matching the declared brand target. Automated scanning on VirusTotal recorded 14 detections out of 95 scanners, and Google Safe Browsing flagged the domain for social‑engineering content. Gridinsoft assigned a trust score of 0 / 100, and the domain appears on a single external blocklist. The evidence points to a classic fake‑airdrop scheme that attempts to harvest credentials or crypto wallet information by exploiting the Google brand.

Open questions include the exact payload delivered to victims and whether the infrastructure leveraged additional compromised hosts beyond the single IP address. Defenders should add euler.airdropsalert.icu to blocklists, monitor DNS queries for the associated Cloudflare name servers, and enforce strict URL filtering for any request to the domain. Incident responders should also correlate logs for connections to 192.178.155.99 and consider threat‑intel sharing of the domain, registration details, and detection signatures with partners.
