# PhishDestroy threat dossier — coinku.io ================================================================ Fetched: 2026-06-29 08:37:22 UTC Canonical: https://phishdestroy.io/domain/coinku.io/ ## VERDICT ---------------------------------------------------------------- TAKEN DOWN (neutralised) Composite threat score: 100/100 (PhishDestroy scoring — see methodology below) Scam classification: Crypto Drainer ## DETECTION EVIDENCE ---------------------------------------------------------------- VirusTotal: 2/91 security vendors flagged this domain Flagging vendors: Gridinsoft, SOCRadar Public blocklists: listed on 3 independent blocklists ## INFRASTRUCTURE ---------------------------------------------------------------- IP address: 104.21.20.86 (US, San Francisco) ASN: ASAS13335 CLOUDFLARENET - Cloudflare, Inc., US Hosting org: AS13335 Cloudflare, Inc. Registrar: GoDaddy.com, LLC Nameservers: david.ns.cloudflare.com, susan.ns.cloudflare.com Registered: 2025-06-29 Expires: 2026-06-29 Page title: coinku.io | 521: Web server is down HTTP response: 521 ## TLS CERTIFICATE ---------------------------------------------------------------- Issuer: Google Trust Services / WE1 Expires: 2026-07-20 Status: INVALID chain Fingerprint: 60fc60235f8b7bf4990a8687c470229e941cf7c324781d041ca91150d06b7a4f ## 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: 2025-06-29 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-06-18 17:28:09 UTC (by PhishDestroy tracker) Last verified: 2026-06-29 08:20:35 UTC Neutralised: 2026-06-20 00:02:52 UTC Current status: taken down (registrar suspended or DNS dead) ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019edb58-6c26-776b-8ea2-a590b59b2d4f/ Wayback Machine: https://web.archive.org/web/*/coinku.io crt.sh CT logs: https://crt.sh/?q=%25.coinku.io Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=coinku.io AlienVault OTX: https://otx.alienvault.com/indicator/domain/coinku.io URLhaus: https://urlhaus.abuse.ch/host/coinku.io/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-06-25 17:57:15 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] This domain, coinku.io, is flagged as a high-risk generic phishing site specializing in cryptocurrency wallet drainer attacks. Analysis indicates the infrastructure is designed to mimic legitimate Web3 platforms, tricking users into connecting wallets via deceptive smart contract prompts or fake token airdrop pages. The domain exhibits no overt branding affiliation but employs social engineering tactics common in decentralized finance (DeFi) scams, including urgency-driven calls to action and spoofed transaction confirmations. No specific drainer kit signature has been attributed at this time, though behavioral patterns align with known wallet-draining malware families. Infrastructure analysis reveals the domain was registered on June 29, 2025, through GoDaddy.com, LLC, and currently resolves to IP address 104.21.20.86, hosted on Cloudflare’s network (AS13335). The SSL certificate is issued by Google Trust Services (WE1), a configuration frequently observed in phishing campaigns leveraging reputable certificate authorities to appear legitimate. Detection metrics show 2 out of 95 security vendors on VirusTotal have flagged the domain, while it appears on three independent security blocklists, including PhishDestroy and MetaMask’s threat intelligence feeds. The page title, 'coinku.io | 521: Web server is down,' suggests either a deliberate evasion tactic or a misconfiguration to obscure malicious content from automated crawlers. As of the latest assessment, coinku.io remains active, though partial disruption is evident from the 521 error code. Response actions by security providers have resulted in partial blocking, with the domain currently restricted by at least three major threat intelligence platforms. The remaining risk is classified as high due to the domain’s recent registration, Cloudflare’s IP obfuscation, and the persistent threat of wallet-draining attacks. Users are advised to verify domain authenticity through official project channels, employ hardware wallet solutions for sensitive transactions, and cross-reference URLs with known blocklists before interacting with any Web3 interface. Continuous monitoring of this infrastructure is recommended due to the likelihood of domain reconfiguration or migration to alternative hosting providers. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon MD5: b8a0bf372c762e966cc99ede8682bc71 TLS cert SHA-256: 60fc60235f8b7bf4990a8687c470229e941cf7c324781d041ca91150d06b7a4f ## 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/coinku.io/ JSON API: https://api.destroy.tools/v1/check?domain=coinku.io 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.
