## TLS CERTIFICATE
----------------------------------------------------------------
Issuer:     Google Trust Services / WE1
Expires:    2026-08-25
Status:     INVALID chain
Fingerprint: 0dc0be3d837e60b4433d84c67385bdc354bb83307d80c71fb67d87f1beec53c6
Subject Alternative Names (related infrastructure — often same operator):
  - webflow.io

## 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: 2013-05-08 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration)
First detected:    2026-06-27 14:15:43 UTC (by PhishDestroy tracker)
Last verified:     2026-06-29 00:20:41 UTC
Neutralised:       2026-06-27 18:17:01 UTC
Current status:    taken down (registrar suspended or DNS dead)

## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-06-27 14:25:49 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.]

This domain is flagged as a high-risk credential theft infrastructure impersonating KuCoin, a major cryptocurrency exchange. The site presents a fraudulent login interface designed to harvest user credentials, enabling unauthorized access to crypto portfolios and subsequent financial theft. Analysis indicates this is not a generic phishing attempt but a targeted attack against KuCoin users, leveraging brand familiarity to deceive victims.  Infrastructure analysis reveals the following technical indicators: the domain auth--apps-kucooin-sso---cdnn.webflow.io was registered through MarkMonitor, Inc. on May 8, 2013, though the malicious subdomain appears to be a recent addition. It currently resolves to IP address 172.64.151.8 and remains active. The page title, 'KuCoin: Sign-in | Access Your Crypto Portfolio,' directly mimics the legitimate KuCoin login portal. VirusTotal detection shows 11 out of 95 security vendors have flagged this domain as malicious. The SSL certificate is issued by Google Trust Services, which, while legitimate, is frequently abused in phishing campaigns to lend a false sense of security. No reputable blocklists or trust scores currently reflect this domain as benign, reinforcing its malicious classification.  Mitigation against this credential theft threat requires immediate action from both users and security teams. Users who may have interacted with this domain should assume their credentials are compromised and initiate password resets on the legitimate KuCoin platform, enabling multi-factor authentication if not already active. Security teams should block the domain and its resolving IP (172.64.151.8) at the network perimeter, including firewalls and email gateways, to prevent further access. Monitoring for similar subdomain patterns (e.g., 'auth--apps-*') on webflow.io or other content delivery networks can help identify related threats. Organizations should also educate users on recognizing impersonation tactics, such as verifying domain names for subtle misspellings or unusual subdomains, and reporting suspicious login pages immediately. Given the high-risk nature of this infrastructure, proactive hunting for related indicators of compromise is recommended.

## EVIDENCE HASHES
----------------------------------------------------------------
Favicon MD5:       1f894f487d068a2ced95d5cd4f88598c
TLS cert SHA-256:      0dc0be3d837e60b4433d84c67385bdc354bb83307d80c71fb67d87f1beec53c6

## 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.
