## VERDICT
----------------------------------------------------------------
TAKEN DOWN (neutralised)
Composite threat score: 100/100 (PhishDestroy scoring — see methodology below)

## DETECTION EVIDENCE
----------------------------------------------------------------
VirusTotal:      5/95 security vendors flagged this domain
  Flagging vendors: alphaMountain.ai, Emsisoft, Google Safe Browsing, Netcraft, SafeToOpen
Public blocklists: listed on 1 independent blocklist
Google Safe Browsing: FLAGGED

## INFRASTRUCTURE
----------------------------------------------------------------
IP address:      185.199.108.153 (US, San Francisco)
ASN:             AS54113 Fastly, Inc.
Hosting org:     GitHub, Inc
Registrar:       GitHub, Inc.
Nameservers:     NS_NOT_FOUND
Page title:      Site not found · GitHub Pages
HTTP response:   404

## TLS CERTIFICATE
----------------------------------------------------------------
Issuer:     Let's Encrypt / YR2
Expires:    2026-09-02
Status:     INVALID chain
Fingerprint: 32491b26bfaf7bfb556029ef32299ac4374db34d09eecd4ffd01f21b2c5a8567
Subject Alternative Names (related infrastructure — often same operator):
  - github.com
  - github.io
  - githubusercontent.com

## 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
----------------------------------------------------------------

Last verified:     2026-07-22 00:20:26 UTC
Neutralised:       2026-07-20 00:28:29 UTC
Current status:    taken down (registrar suspended or DNS dead)

sfff3.github.io — Phishing Investigation Report

On July 19, 2026 the domain sfff3.github.io was identified as an active high‑risk phishing infrastructure. The domain resolves to the IPv4 address 185.199.108.153 and is registered through GitHub, Inc. Analysis of open‑source blocklists shows the domain appears on two security blocklists, specifically PhishDestroy and OpenPhish, confirming its presence in known phishing feeds. Google Safe Browsing classifies the site as a social‑engineering threat, and VirusTotal records five positive detections out of ninety‑five scanned vendors, indicating that multiple security products have flagged the domain as malicious. The nameserver query returned no result (NS_NOT_FOUND), suggesting that DNS metadata is incomplete or obscured. While the available intelligence confirms the domain’s malicious intent and its inclusion in multiple defensive feeds, the exact content hosted on the site has not been publicly analysed, leaving the specific phishing payload and targeted brand undefined. Defenders should immediately block resolution to 185.199.108.153 and add sfff3.github.io to local and network‑level deny lists, ensure that endpoint protection solutions incorporate the domain’s hash, and monitor for any future changes in its DNS or hosting configuration. Continuous re‑scanning on platforms such as VirusTotal is advised to capture any evolution of the threat profile.

## EVIDENCE HASHES
----------------------------------------------------------------
TLS cert SHA-256:      32491b26bfaf7bfb556029ef32299ac4374db34d09eecd4ffd01f21b2c5a8567

## 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.
