## 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: 2026-05-12 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration)

First reported:    2026-05-29 21:02:25 UTC (abuse notice filed)
Last verified:     2026-06-27 20:20:35 UTC
Neutralised:       2026-06-06 17:29:31 UTC
Current status:    taken down (registrar suspended or DNS dead)

## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-06-26 04:10:34 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.]

This domain, d-feiishu.com.cn, poses as an official Feishu web login portal to deceive users into entering corporate credentials. The site mimics the legitimate Feishu open platform, displaying the page title '飞书开放平台官方下载｜飞书网页端登录入口·智能办公解决方案' to appear authentic. Users tricked into submitting login details risk unauthorized access to sensitive work accounts, internal communications, and proprietary data stored within Feishu or integrated enterprise systems.  Analysis indicates this is a calculated phishing operation. The domain was registered on May 12, 2026, through 万商云集（成都）科技股份有限公司, a registrar frequently associated with suspicious registrations. It resolves to the IP address 38.76.168.119 and is flagged by 15 out of 95 security vendors on VirusTotal, including entries on two major blocklists. Technical indicators reveal the use of Nginx for hosting, HTTP/3 protocol support, and HSTS headers, suggesting an attempt to appear legitimate while maintaining operational security.  If you or someone in your organization visited d-feiishu.com.cn and entered login credentials, immediate action is required. First, reset the compromised Feishu password and any reused credentials across other platforms. Enable multi-factor authentication on all accounts if not already active. Notify your IT or security team to monitor for unauthorized access or anomalous activity. If corporate devices were used, scan them for malware using updated security tools. Finally, report the incident to internal security teams and consider submitting the domain to additional threat intelligence platforms to aid in broader detection efforts.

## EVIDENCE HASHES
----------------------------------------------------------------
PhishDestroy Case ID:  PD-20260529-D01B5C
Favicon MD5:       dc43371d05f5910a5b3b6bebb1288033
TLS cert SHA-256:      15a20a6a969d7bb76c55fff4e54716b1c288639dca811b2864558635029f056f

## 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 (volunteer 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.
