## 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: 2014-08-11 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration)

Last verified:     2026-07-14 12:20:41 UTC
Neutralised:       2026-07-09 12:41:30 UTC
Current status:    taken down (registrar suspended or DNS dead)

## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-07-07 14:36:03 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.]

Analysis indicates that estudiocils.com.ar is a generic phishing domain. The page title claims to represent a legitimate accounting service, Estudio CILS, based in Bariloche, Argentina, with over ten years of experience. However, the domain is not associated with any known drainer kit or specific brand impersonation beyond the generic service label. The threat is classified as high risk due to its active status and widespread blocklisting.

Technical indicators confirm the domain's malicious nature. VirusTotal reports a detection ratio of 17/95 security vendors flagging the domain. The domain was created on August 11, 2014, and is registered through the Argentine registrar nicar. It resolves to IP address 200.58.110.185. The domain appears on three security blocklists, including PhishingArmy, OISD, and BLP-Malware. Google Safe Browsing status is not specified in the intelligence, but the domain is included in one AlienVault OTX threat intelligence pulse. The SSL certificate is issued by Sectigo Limited.

Current status indicates the domain remains active and accessible. No takedown actions have been reported. The primary risk to users is credential theft through a fake login page or data harvesting under the guise of a legitimate accounting firm. Recommended actions include blocking the domain at the network level, adding it to blocklists, and advising users to avoid interacting with the site. Continuous monitoring is advised given the domain's historical registration and persistent hosting.

## EVIDENCE HASHES
----------------------------------------------------------------
Favicon MD5:       e2f16791acd1d1e30b37701c0ba8c996
TLS cert SHA-256:      05ea722b38705d9c21e998810f74adf37fa8aaa65accafe90727ac9267cfdf06

## 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.
