web[.]api-listing-opensea[.]com

Analysis of web.api-listing-opensea.com confirms its classification as a crypto scam domain impersonating OpenSea, a known non-fungible token (NFT) marketplace. The domain was registered on September 10, 2024, through Hosting Concepts B.V. d/b/a Registrar.eu, with nameservers distributed across ina1.registrar.eu, ina2.registrar.eu, ina3.registrar.eu, and ns1.openprovider.nl. Infrastructure analysis reveals the domain resolved to 15.197.130.221, an IP address hosted on Amazon.com, Inc.'s AS16509 network in the United States. No SSL certificate was detected, increasing the likelihood of interception or manipulation of user data. The page title, 'api-listing-opensea.com,' directly references OpenSea, aligning with the scam type labeled as a crypto scam.

At the time of assessment, the domain was flagged by 14 of 95 security vendors on VirusTotal, indicating moderate detection coverage. It appears on one security blocklist and is blocked by PhishDestroy. The Gridinsoft trust score of 0/100 further corroborates its malicious classification. The domain is currently offline, though defenders should note its prior resolution and registration details for retrospective hunting.

Uncertainties remain regarding the exact mechanics of the scam, such as whether it involved fake NFT listings, wallet drainers, or credential harvesting, as the page content was not analyzed. Defenders are advised to treat this domain as confirmed malicious infrastructure and incorporate its indicators—including the IP address, registrar details, and nameservers—into detection rules and blocklists. Historical DNS logs should be reviewed for connections to 15.197.130.221 or the listed nameservers to identify potential compromised endpoints. Given the domain's association with a high-profile brand, monitoring for similar naming conventions (e.g., 'api-listing-[brand]') may help preemptively identify related threats.
