# PhishDestroy threat dossier — kast-io.firebaseapp.com ================================================================ Fetched: 2026-07-27 04:03:03 UTC Canonical: https://phishdestroy.io/domain/kast-io.firebaseapp.com/ ## VERDICT ---------------------------------------------------------------- TAKEN DOWN (neutralised) Composite threat score: 83/100 (PhishDestroy scoring — see methodology below) Scam classification: Brand Impersonation ## DETECTION EVIDENCE ---------------------------------------------------------------- VirusTotal: 12/94 security vendors flagged this domain Flagging vendors: ADMINUSLabs, ChainPatrol, alphaMountain.ai, BitDefender, CyRadar, Emsisoft, G-Data, Kaspersky, Lionic, Netcraft, Sophos, Webroot Public blocklists: listed on 4 independent blocklists ## INFRASTRUCTURE ---------------------------------------------------------------- IP address: 199.36.158.100 (US, Mountain View) ASN: AS54113 Fastly, Inc. Hosting org: Google LLC Registrar: Google LLC Nameservers: NS_NOT_FOUND Registered: 2026-04-04 Page title: Site Not Found HTTP response: 404 ## TLS CERTIFICATE ---------------------------------------------------------------- Issuer: Google Trust Services / WR4 Expires: 2026-06-18 Status: INVALID chain Fingerprint: fc055da89cfe63a5e2d9e5ad8d257bd0e3314925f5f811a5e21652132ed62610 Subject Alternative Names (related infrastructure — often same operator): - firebaseapp.com ## 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: 2026-04-04 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-04-04 15:30:12 UTC (by PhishDestroy tracker) First reported: 2026-04-04 15:26:33 UTC (abuse notice filed) Last verified: 2026-07-27 04:21:38 UTC Neutralised: 2026-07-21 03:25:21 UTC Current status: taken down (registrar suspended or DNS dead) ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019d5875-423d-72d5-971f-247620251af0/ Wayback Machine: https://web.archive.org/web/*/kast-io.firebaseapp.com crt.sh CT logs: https://crt.sh/?q=%25.kast-io.firebaseapp.com Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=kast-io.firebaseapp.com AlienVault OTX: https://otx.alienvault.com/indicator/domain/kast-io.firebaseapp.com URLhaus: https://urlhaus.abuse.ch/host/kast-io.firebaseapp.com/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-04-04 15:38:45 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] kast-io.firebaseapp.com Crypto Drainer Alert — Impersonates Kast PhishDestroy analysts identified kast-io.firebaseapp.com as a live crypto-draining site under active investigation. The domain masquerades as the official Kast IO platform to trick users into connecting wallets and approving malicious token approvals that silently drain funds. Despite resolving to 199.36.158.100 via Google’s Firebase infrastructure, current threat intelligence shows zero detections out of 95 VirusTotal engines, underscoring the need for community vigilance. This domain was flagged through PhishDestroy’s seed-based monitoring on 2024-06-04. It is registered through Google LLC and leverages a Google Trust Services SSL certificate to appear legitimate. The Firebase hosting further complicates detection, blending in with benign Google infrastructure. Given the absence of antivirus coverage, Kast IO users should treat any Firebase subdomain claiming to offer wallet integrations as suspicious unless explicitly verified through Kast IO’s official channels. If you visited kast-io.firebaseapp.com, immediately revoke any token approvals via your wallet’s settings and disconnect the site. Check recent transactions for unauthorized transfers and consider transferring remaining assets to a new wallet. Report the domain to PhishDestroy’s database and to Kast IO’s security team so they can coordinate takedown efforts with Google Firebase. ## EVIDENCE HASHES ---------------------------------------------------------------- TLS cert SHA-256: fc055da89cfe63a5e2d9e5ad8d257bd0e3314925f5f811a5e21652132ed62610 ## 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/kast-io.firebaseapp.com/ JSON API: https://api.destroy.tools/v1/check?domain=kast-io.firebaseapp.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.
