Registrar: Dynadot LLC Nameservers: ns1.dyna-ns.net, ns2.dyna-ns.net Registered: 2025-12-14 Page title: mailservers31-coinbase.online HTTP response: 200 ## TLS CERTIFICATE ---------------------------------------------------------------- Issuer: none Status: INVALID chain ## ABUSE-REPORT HISTORY (evidence of registrar non-response) ---------------------------------------------------------------- Status: CLOSED — no report required. This domain was neutralised before the abuse-report cycle could be dispatched — either the hosting provider / registrar suspended it on their own, the DNS went dead, or the operator abandoned the infrastructure. PhishDestroy keeps the evidence bundle on file for audit but no formal notice was sent. ## TIMELINE ---------------------------------------------------------------- Domain registered: 2025-12-14 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-02-25 02:39:27 UTC (by PhishDestroy tracker) First reported: 2025-12-16 07:31:16 UTC (abuse notice filed) Last verified: 2026-05-31 09:20:38 UTC Neutralised: 2026-03-01 04:28:35 UTC Current status: taken down (registrar suspended or DNS dead) ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019b2611-96fc-7696-9f09-c231e1bd4d83/ Wayback Machine: https://web.archive.org/web/*/mailservers31-coinbase.online crt.sh CT logs: https://crt.sh/?q=%25.mailservers31-coinbase.online Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=mailservers31-coinbase.online AlienVault OTX: https://otx.alienvault.com/indicator/domain/mailservers31-coinbase.online URLhaus: https://urlhaus.abuse.ch/host/mailservers31-coinbase.online/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-03-19 00:03:28 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] PhishDestroy identifies mailservers31-coinbase.online as a high-risk phishing domain designed to impersonate the well-known cryptocurrency platform Coinbase. This domain leverages brand impersonation tactics to deceive users into believing they are interacting with a legitimate Coinbase service, potentially exposing sensitive information such as login credentials and financial data. The fraudulent nature of this domain poses a significant threat to users seeking to access Coinbase-related services. The domain mailservers31-coinbase.online was registered through Dynadot LLC on December 14, 2025. It resolves to the IP address 199.59.243.228 and has been flagged by 18 out of 95 antivirus engines on VirusTotal, indicating considerable suspicion across multiple security platforms. Additionally, the domain appears on two known security blocklists, underscoring its malicious reputation. Its page title, simply the domain name itself, lacks any reassurance of legitimacy, aligning with standard phishing tactics that rely on brand mimicry rather than authentic user experience. Currently, mailservers31-coinbase.online is offline, which reduces immediate risk but does not eliminate the threat from potential future iterations or related domains. PhishDestroy advises users to remain vigilant when accessing Coinbase platforms, always verify URLs carefully, and avoid entering personal credentials on suspicious sites. Security teams should continue to monitor for similar domains leveraging the Coinbase brand to prevent credential theft and financial fraud. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon SHA-256: 5a0687ea8c9aa404a7724490f046e30023ec6b5aa81d01ae4f225889a64174f6 ## SCORING METHODOLOGY ---------------------------------------------------------------- Composite score is NOT derived from VirusTotal alone. PhishDestroy aggregates: - VirusTotal positive ratio - Public blocklist consensus (MetaMask, ScamSniffer, OpenPhish, PhishTank, URLhaus, CryptoFirewall, SEAL, Polkadot, Enkrypt, Phishunt, DiscordPhishing, PhishingDB) - Cloaking detection (HTTP 666 or rendering delta between bot and real visitor) - DNS-filter consensus (Quad9, CleanBrowsing, NextDNS, AdGuard, Cloudflare, etc.) - AlienVault OTX pulses + Cloudflare Radar + Google Safe Browsing - URLScan / URLQuery verdicts - Brand-impersonation heuristics (DOM analysis of forms, logos, wording) - Known phishing-kit fingerprinting (favicon hash, JS obfuscation signatures) - Wallet-drainer family classification (Angel, MS, Rainbow, Pink, Inferno, ...) - Free-TLS vs paid-cert ratio (throwaway infrastructure signal) - Registrar/hosting abuse history (this registrar's track record) - Human researcher sign-off (volunteer takedown team) A domain present in our database is ALREADY flagged. A low VT count by itself does NOT mean the domain is safe — new scam domains routinely show 0/95 VT for their first 7–30 days while actively draining wallets. Always cross-reference the composite score and the individual indicators above, not just VT. ## CORRECTIONS / APPEALS ---------------------------------------------------------------- Full HTML report: https://phishdestroy.io/domain/mailservers31-coinbase.online/ JSON API: https://api.destroy.tools/v1/check?domain=mailservers31-coinbase.online Appeal a flag: https://phishdestroy.io/appeals/ (responded to within 48 hours, FP rate <0.01%) Submit a report: https://t.me/PhishDestroy_bot About PhishDestroy: volunteer-driven open-source threat-intelligence platform.
