Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] authentication-login-page.duckdns.org — Credential Phishing Authentication-login-page.duckdns.org is an active credential‑phishing domain observed on 26 July 2026. Technical inspection shows the hostname resolves to the public IPv4 address 13.50.248.23. The domain is hosted under the dynamic DNS service DuckDNS, as indicated by the registration record. Google Safe Browsing classifies the site as a social‑engineering threat, and the domain appears on two independent security blocklists. Both PhishDestroy and OpenPhish have listed the domain as malicious, confirming its use in phishing campaigns. VirusTotal analysis reports that 15 of 91 scanned security vendors flag the host as malicious, providing additional corroboration of its hostile nature. No authoritative nameserver information is available; the NS lookup returned NS_NOT_FOUND, which is consistent with the use of a dynamic DNS provider that often omits traditional NS records. The available intelligence does not include SSL/TLS details, HTTP response codes, or page‑title metadata, so the exact content served by the site remains undocumented. Given the combination of dynamic‑DNS registration, IP resolution, multiple blocklist listings, and the Safe Browsing social‑engineering label, the domain should be treated as high‑risk. Defensive actions include adding the domain and its resolving IP to network‑level deny lists, configuring web‑proxy filters to block HTTP(S) requests to the host, and ensuring endpoint protection solutions receive the latest indicator updates from the blocklist providers. Continuous monitoring of the IP address and any future DNS changes is advised, as dynamic DNS services can rapidly reassign hosts. Organizations should educate users about unsolicited login prompts and enforce multi‑factor authentication to mitigate credential compromise should a user encounter the site. ## EVIDENCE HASHES ---------------------------------------------------------------- TLS cert SHA-256: 7414a4fe7a0da4229077be434fbbee8e722bdedc2cd09c95931af6713e27fefb ## 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/authentication-login-page.duckdns.org/ JSON API: https://api.destroy.tools/v1/check?domain=authentication-login-page.duckdns.org 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.
