Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] Is algo-course.online a phishing site? Analysis of the domain algo-course.online indicates that it was registered through GoDaddy.com, LLC on July 15 2026 and is currently using the Cloudflare nameservers chan.ns.cloudflare.com and jason.ns.cloudflare.com. The domain resolves to the IPv4 address 188.137.244.143, which is the sole host observed for this infrastructure. The domain has been classified as a generic phishing threat and is listed as active. It is presently blocked by PhishDestroy and appears on one external security blocklist, confirming that at least one third‑party service has identified it as malicious. VirusTotal records show that the domain was scanned by 91 AV vendors, none of which reported a detection; the absence of a detection does not constitute evidence of benign behavior and should be interpreted conservatively. The limited public data does not include a page title, SSL certificate details, HTTP response codes, or any observed content, leaving the exact phishing lure or targeted brand undefined. Consequently, defenders must assume the domain is being used to harvest credentials or personal information until further analysis becomes available. Recommended mitigation steps include adding the domain and its resolved IP address to network deny lists, updating web‑proxy and DNS filtering rules, and monitoring outbound connections for traffic to 188.137.244.143. Because the domain is hosted on Cloudflare, any future changes to IP or nameserver configuration may occur without notice, so periodic re‑resolution is advisable. Security teams should also watch for any new detections on VirusTotal or other reputation services, and consider submitting the domain to additional analysis platforms to accelerate attribution. ## EVIDENCE HASHES ---------------------------------------------------------------- PhishDestroy Case ID: PD-20260724-5C4551 Favicon MD5: 0759a4206b9105a0debfb900706dfab1 TLS cert SHA-256: d1f48ff83addd9f6b3b8f87fa493cc9c0986bb645ca7435bf0175afbecf56848 ## 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/algo-course.online/ JSON API: https://api.destroy.tools/v1/check?domain=algo-course.online 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.
