No abuse reports filed yet — this domain is waiting for the next cycle of our automated abuse-reporter. ## TIMELINE ---------------------------------------------------------------- Domain registered: 2018-12-11 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-04-10 16:27:11 UTC (by PhishDestroy tracker) First reported: 2026-04-10 16:27:01 UTC (abuse notice filed) Last verified: 2026-07-04 16:20:36 UTC Neutralised: 2026-04-29 09:28:09 UTC Current status: ACTIVE — cloaked behind HTTP 666 to evade scanners ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019d7791-9c22-7559-b2b0-09a422400be2/ Wayback Machine: https://web.archive.org/web/*/c3.ahra.org.ar crt.sh CT logs: https://crt.sh/?q=%25.c3.ahra.org.ar Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=c3.ahra.org.ar AlienVault OTX: https://otx.alienvault.com/indicator/domain/c3.ahra.org.ar URLhaus: https://urlhaus.abuse.ch/host/c3.ahra.org.ar/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-04-10 16:29:10 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] PhishDestroy identifies c3.ahra.org.ar as an active credential theft portal posing as a legitimate login interface. This domain employs deceptive tactics to harvest user credentials, placing visitors at immediate risk of account compromise. The site masquerades under a legitimate-looking subdomain (c3.ahra.org.ar) to bypass initial suspicion while facilitating unauthorized access to sensitive login information. This domain was flagged by security researchers due to its malicious intent and aligns with known tactics used by credential theft campaigns. Threat intelligence confirms 5 out of 95 VirusTotal security vendors have detected malicious activity, while the domain resolves to IP 74.50.97.108 and holds a valid Let's Encrypt SSL certificate. Registered through NICAR on December 11, 2018, this domain has been active for over five years, providing ample time to establish trustworthiness while remaining unchecked by traditional blocklists. The combination of an aged domain, valid SSL certificate, and partial detection rate highlights the sophistication of this credential theft campaign. To mitigate risk, users must avoid entering any credentials or sensitive information on this domain. Organizations should block c3.ahra.org.ar at the network level and educate users about recognizing impersonation attempts. If credentials were mistakenly entered, immediately reset passwords and enable multi-factor authentication across affected accounts. Report the domain to relevant authorities (e.g., CERT, browser vendors) to expedite takedown efforts and prevent further exploitation. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon MD5: 626d5d281caf516265a47cda971c21ab TLS cert SHA-256: c0476173add7d0e63cd11eb420cb3a49d47752fb6921f605f83a9def9f73ad31 ## 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/c3.ahra.org.ar/ JSON API: https://api.destroy.tools/v1/check?domain=c3.ahra.org.ar 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.
