# PhishDestroy threat dossier — isithin.com ================================================================ Fetched: 2026-07-23 01:59:49 UTC Canonical: https://phishdestroy.io/domain/isithin.com/ ## VERDICT ---------------------------------------------------------------- CRITICAL THREAT — DO NOT VISIT Composite threat score: 100/100 (PhishDestroy scoring — see methodology below) ## DETECTION EVIDENCE ---------------------------------------------------------------- VirusTotal: 6/91 security vendors flagged this domain Flagging vendors: alphaMountain.ai, CRDF, Forcepoint ThreatSeeker, Fortinet, Gridinsoft, SOCRadar AlienVault OTX: 4 pulses (threat-intel feed mentions) Public blocklists: listed on 1 independent blocklist ## INFRASTRUCTURE ---------------------------------------------------------------- IP address: 159.198.36.123 (US, Chicago) ASN: AS22612 Namecheap, Inc. Hosting org: Namecheap, Inc. Registrar: NameSilo, LLC !!! REGISTRAR INTEGRITY ALERT — NameSilo !!! NameSilo is a registrar documented by PhishDestroy as (1) publicly lying about received abuse reports, (2) shielding a $20M+ Monero-theft operation (xmrwallet.com) for 10 continuous years, and (3) retaliating against PhishDestroy by getting our X/Twitter account @Phish_Destroy banned after we published the evidence. Researchers/victims must ALWAYS CC compliance@icann.org on every abuse ticket — NameSilo has a track record of later claiming reports were never received. Primary sources: https://phishdestroy.io/namesilo-killed-our-twitter https://phishdestroy.io/xmrwallet-namesilo-exposed Nameservers: ["ns1.isithin.com", "ns2.isithin.com"] Page title: International Seafarers Institute HTTP response: 200 ## TLS CERTIFICATE ---------------------------------------------------------------- Issuer: Let's Encrypt / YR2 Expires: 2026-10-14 Status: INVALID chain Fingerprint: b0301c7b45b89d403be606fe4af4183887179b98b07d13248189757b9c673cc6 ## ABUSE-REPORT HISTORY (evidence of registrar non-response) ---------------------------------------------------------------- Status: pending notification queue. No abuse reports filed yet — this domain is waiting for the next cycle of our automated abuse-reporter. ## TIMELINE ---------------------------------------------------------------- First detected: 2026-07-19 12:38:02 UTC (by PhishDestroy tracker) Last verified: 2026-07-23 00:22:35 UTC Current status: ACTIVE / observable ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-07-20 01:56:27 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] isithin.com — Generic Phishing Investigation The domain isithin.com is currently active and hosts a site with the page title International Seafarers Institute. Infrastructure analysis shows the domain is registered through NameSilo, LLC and uses Namecheap, Inc. hosting in the United States, resolving to IP address 159.198.36.123. DNS configuration includes authoritative nameservers ns1.isithin.com and ns2.isithin.com, and the domain publishes an MX record pointing to itself (priority 0, host isithin.com). The site presents a valid TLS certificate from Let’s Encrypt (YR2) and returns HTTP 200 responses. Threat intelligence sources flag the domain: it appears on one security blocklist, is blocked by PhishDestroy, and has been referenced in four AlienVault OTX pulses. VirusTotal scans report six of ninety‑one security vendors flagging the domain as malicious. While the page title suggests a maritime education theme, no additional content analysis is available, leaving the exact phishing payload or credential‑harvesting mechanism unconfirmed. Defenders should block DNS resolution to 159.198.36.123, enforce URL filtering for isithin.com, monitor email traffic for MX usage, and consider adding the domain to internal blocklists pending further investigation. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon MD5: 87284778e99909c72bf57e4e22f45a93 TLS cert SHA-256: b0301c7b45b89d403be606fe4af4183887179b98b07d13248189757b9c673cc6 ## 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 (operator 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/isithin.com/ JSON API: https://api.destroy.tools/v1/check?domain=isithin.com 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: independent open-source threat-intelligence platform.
