Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] This domain, uc-quark.com.cn, is identified as an active credential harvesting phishing infrastructure designed to deceive users into submitting sensitive authentication details through fraudulent login interfaces. Analysis indicates the domain mimics legitimate service portals, likely targeting corporate or financial sector credentials, with the intent to facilitate unauthorized account access or identity theft. The use of Let's Encrypt SSL certificates further enhances the illusion of legitimacy, increasing the likelihood of successful deception. Infrastructure analysis reveals the domain was registered on June 13, 2026, through 浙江贰贰网络有限公司, a registrar frequently associated with high-risk domains. The domain resolves to the IP address 23.145.136.95, which has been flagged in multiple threat intelligence feeds. As of the latest assessment, 9 out of 95 security vendors on VirusTotal have detected this domain as malicious, with additional blocklist entries confirming its classification as a phishing threat. The domain remains active, indicating ongoing operational status. Users who have interacted with uc-quark.com.cn should immediately terminate any active sessions and revoke any credentials entered on the site. It is recommended to conduct a full system scan using updated security tools to detect potential malware or unauthorized access. Affected individuals should monitor accounts for suspicious activity and enable multi-factor authentication where available. Organizations should update internal blocklists to include this domain and its associated IP address, 23.145.136.95, to prevent further exposure. If financial or sensitive data was submitted, affected parties are advised to report the incident to relevant authorities for further investigation. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon MD5: 34d71031511dab829311aa628d52f7d1 TLS cert SHA-256: d783f8e1d459d23f57d0b5c25415426a9c55a9323db3de34cf0c44c61fe0b1b9 ## 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/uc-quark.com.cn/ JSON API: https://api.destroy.tools/v1/check?domain=uc-quark.com.cn 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.
