Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] This domain, khoahoctiengtrung.com, is currently under investigation for generic phishing threats. Analysis indicates that it may be leveraged for phishing activities, such as collecting sensitive information from users under false pretenses. The domain presents itself as a Vietnamese language learning center, which could be used to establish legitimacy and target users seeking educational resources. Infrastructure analysis reveals khoahoctiengtrung.com was registered on August 26, 2019, through P.A. Viet Nam Company Limited. The domain resolves to IP address 103.221.220.79. As of this assessment, there are zero detections out of 95 checked on major blocklists, indicating it is not yet widely recognized as malicious. However, the current status remains active and the domain is being monitored for further threat indicators. Users who have interacted with this site should remain vigilant. It is recommended to avoid entering any personal or financial information and monitor for any signs of phishing attempts. If information was submitted, consider updating credentials and monitor associated accounts for suspicious activity. ## EVIDENCE HASHES ---------------------------------------------------------------- TLS cert SHA-256: 3d506fda73a3ae21ff1395bec22616f42742e73a88afd22ac50cb837cb299d41 ## 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/khoahoctiengtrung.com/ JSON API: https://api.destroy.tools/v1/check?domain=khoahoctiengtrung.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.
