ww25[.]backupcoinbase[.]com

Analysis of ww25.backupcoinbase.com indicates a crypto-focused phishing domain impersonating Coinbase, active since November 13, 2024. The domain was registered through OwnRegistrar, Inc., and currently resolves to 199.59.243.228, an IP address hosted on Amazon.com, Inc. infrastructure (AS16509) in the United States. No SSL certificate was detected, increasing the risk of unencrypted credential interception. The page title, 'backupcoinbase.com,' directly references the targeted brand, and the domain is classified as an airdrop scam, a common tactic for cryptocurrency fraud.

Infrastructure analysis reveals the domain uses Cloudflare nameservers (michael.ns.cloudflare.com, nia.ns.cloudflare.com) alongside managedns1.com nameservers, a configuration that may obscure hosting details. The domain appears on one security blocklist (PhishDestroy) and is flagged by 3 of 95 security vendors on VirusTotal, though the specific detection logic is not publicly detailed. Gridinsoft assigns a trust score of 0/100, reinforcing its malicious classification. As of the report date, the domain is offline, though its prior activity and infrastructure remain a potential threat.

Defenders should treat this domain as high-risk for Coinbase users. Blocklist the domain and IP address, monitor for related subdomains or lookalike domains, and alert users to airdrop scam tactics. The absence of SSL and the use of Cloudflare nameservers are notable indicators for automated detection systems. Further investigation into the phishing kit's distribution methods and associated wallets is recommended to disrupt the broader campaign.
