Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] The domain perf-docs.ru is a confirmed brand impersonation site that specifically targets Microsoft. The page title 'Скачать программу Microsoft Word бесплатно. Безопасная загрузка' (Download Microsoft Word for free. Safe download) is designed to deceive users into believing they are accessing legitimate Microsoft content. This deceptive tactic is aimed at tricking users into downloading potentially harmful software or providing sensitive information, thereby posing a high risk to both individuals and organizations. Analysis indicates that 17 out of 95 security vendors on VirusTotal have flagged this domain as malicious. The domain is registered with Let's Encrypt and currently resolves to the IP address 93.77.165.37, which is located in Russia (RU) and is part of the AS200350 Yandex.Cloud LLC network. The domain appears on 1 security blocklist, further confirming its malicious nature. The SSL certificate, issued by Let's Encrypt, does not provide any assurance of the site's legitimacy, as it is a common practice among threat actors to use trusted certificate authorities to enhance the credibility of their phishing sites. If users have visited perf-docs.ru, they should immediately scan their systems for malware using a reputable antivirus solution. Additionally, users should change any Microsoft account passwords and monitor their accounts for any unauthorized activity. Organizations should update their security policies to block access to this domain and educate employees about the risks of brand impersonation attacks. It is crucial to verify the authenticity of download sources and avoid clicking on suspicious links or downloading software from untrusted websites. ## EVIDENCE HASHES ---------------------------------------------------------------- Favicon MD5: 12c153f9f22b543ffac64776c6d6bb30 TLS cert SHA-256: 4fc5a68c43eb117ab6f2c0853395880d64248f8c08d750a323f3f95d37b62a0c ## 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/perf-docs.ru/ JSON API: https://api.destroy.tools/v1/check?domain=perf-docs.ru 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.
