Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] PhishDestroy identifies btctumblers.net as a malicious domain engineered to deploy a crypto drainer under the guise of a Bitcoin tumbler service. This site tricks users into connecting cryptocurrency wallets with the false promise of anonymizing transactions, only to silently drain funds via unauthorized smart contract interactions. The threat is elevated due to the irreversible nature of cryptocurrency theft and the use of social engineering targeting privacy-conscious users of tumblers and mixers. This domain was flagged by PhishDestroy with cross-validation from security vendors: VirusTotal reports 1 out of 95 engines detecting the threat, indicating low initial detection but high potential for harm. The domain is registered through NICENIC INTERNATIONAL GROUP CO., LIMITED, which has been associated with anonymity-friendly registrations. It resolves to IP 104.21.58.202 and was created unusually far in the future—December 28, 2025—suggesting possible domain pre-registration for future phishing campaigns or testing. Despite having a valid SSL certificate issued by Google Trust Services, this is not indicative of legitimacy, as phishing sites commonly use trusted issuers to appear credible. If you have visited btctumblers.net or connected a wallet to the site, immediately revoke any unauthorized smart contract permissions using tools like revoke.cash or your wallet’s built-in dApp connection manager. Disconnect the wallet from the site, transfer remaining assets to a fresh wallet with a new seed phrase, and scan your device for malware. Avoid interacting with any future links from this domain. Report the site to your antivirus provider and to PhishDestroy using the unique seed ca13f2 for further analysis and community protection. ## EVIDENCE HASHES ---------------------------------------------------------------- PhishDestroy Case ID: PD-20260331-BED8EB Favicon MD5: c2e216553b31cba44908fa84d1b04571 TLS cert SHA-256: 23d3597c9fbe8cebc6a94e45c12365a9f45b5b66791374cd74ae1a505c27793d ## 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/btctumblers.net/ JSON API: https://api.destroy.tools/v1/check?domain=btctumblers.net 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.
