# PhishDestroy threat dossier — zhishiku88.com ================================================================ Fetched: 2026-07-17 11:17:06 UTC Canonical: https://phishdestroy.io/domain/zhishiku88.com/ ## VERDICT ---------------------------------------------------------------- TAKEN DOWN (neutralised) Composite threat score: 100/100 (PhishDestroy scoring — see methodology below) Scam classification: Generic Phishing ## DETECTION EVIDENCE ---------------------------------------------------------------- VirusTotal: 12/91 security vendors flagged this domain Flagging vendors: ADMINUSLabs, alphaMountain.ai, BitDefender, Chong Lua Dao, CyRadar, ESET, Forcepoint ThreatSeeker, Fortinet, G-Data, Gridinsoft, SOCRadar, Sophos Public blocklists: listed on 1 independent blocklist ## INFRASTRUCTURE ---------------------------------------------------------------- IP address: 172.67.180.134 (US, San Francisco) ASN: ASAS13335 CLOUDFLARENET - Cloudflare, Inc., US Hosting org: AS13335 Cloudflare, Inc. Registrar: Name SRS AB Nameservers: magali.ns.cloudflare.com, randall.ns.cloudflare.com Registered: 2026-04-02 Expires: 2027-04-02 Page title: 区块链知识库 | 区块链知识库 HTTP response: 502 ## TLS CERTIFICATE ---------------------------------------------------------------- Issuer: Let's Encrypt / YE1 Expires: 2026-08-29 Status: INVALID chain Fingerprint: cbfe4b58c51128ac2a52d879f832bf3ee1f13b585495a2f6e3a7bd356ad8910e ## 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: 2026-04-02 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-06-22 23:46:06 UTC (by PhishDestroy tracker) First reported: 2026-06-22 23:00:10 UTC (abuse notice filed) Last verified: 2026-07-17 12:20:41 UTC Neutralised: 2026-06-23 00:01:45 UTC Current status: taken down (registrar suspended or DNS dead) ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019ef14a-e678-7319-b44f-bc80cf833291/ URLQuery: https://urlquery.net/report/15da430c-90be-4e9d-9abd-99c7695ea17f Wayback Machine: https://web.archive.org/web/*/zhishiku88.com crt.sh CT logs: https://crt.sh/?q=%25.zhishiku88.com Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=zhishiku88.com AlienVault OTX: https://otx.alienvault.com/indicator/domain/zhishiku88.com URLhaus: https://urlhaus.abuse.ch/host/zhishiku88.com/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-06-25 19:28:55 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] This domain is classified under an elevated risk level due to its association with generic_phishing activity. Analysis indicates the site mimics a blockchain knowledge repository, likely designed to harvest credentials or distribute malicious payloads under the guise of educational content. The page title, "区块链知识库 | 区块链知识库," reinforces the deceptive theme, targeting users seeking blockchain-related information. Infrastructure analysis reveals the following technical indicators: the domain is registered through Name SRS AB and resolves to IP address 172.67.180.134. It was created on April 02, 2026, an anomalous future date suggesting potential registration irregularities or data manipulation. VirusTotal reports 12 out of 95 security vendors flagging the domain as malicious. Additionally, the domain appears on one security blocklist, and its current status is offline, though this does not preclude future reactivation. No legitimate trust scores or reputable associations were identified. Mitigation steps specific to this threat type include blocking the domain and its resolving IP (172.67.180.134) at the network perimeter. Organizations should deploy email and web filtering rules to prevent user access to the domain and monitor for phishing attempts leveraging similar blockchain-themed lures. Endpoint detection systems should be configured to alert on connections to the IP or domain. Users who may have interacted with the site should be instructed to reset credentials, particularly if blockchain wallets or financial services were involved. Security teams should review logs for prior connections to 172.67.180.134 or related domains registered through Name SRS AB, as these may indicate broader compromise attempts. ## EVIDENCE HASHES ---------------------------------------------------------------- PhishDestroy Case ID: PD-20260622-5BC0FC TLS cert SHA-256: cbfe4b58c51128ac2a52d879f832bf3ee1f13b585495a2f6e3a7bd356ad8910e ## 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/zhishiku88.com/ JSON API: https://api.destroy.tools/v1/check?domain=zhishiku88.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.
