# PhishDestroy threat dossier — t-mobile.siydbc.top ================================================================ Fetched: 2026-06-21 15:41:07 UTC Canonical: https://phishdestroy.io/domain/t-mobile.siydbc.top/ ## VERDICT ---------------------------------------------------------------- TAKEN DOWN (neutralised) Composite threat score: 100/100 (PhishDestroy scoring — see methodology below) ## DETECTION EVIDENCE ---------------------------------------------------------------- VirusTotal: 19/91 security vendors flagged this domain Flagging vendors: ADMINUSLabs, BitDefender, Chong Lua Dao, Cluster25, CRDF, CyRadar, ESET, Emsisoft, Fortinet, G-Data, Google Safebrowsing, Gridinsoft, LevelBlue, Lionic, Netcraft, SOCRadar, Sophos, VIPRE, Webroot Public blocklists: listed on 1 independent blocklist ## INFRASTRUCTURE ---------------------------------------------------------------- IP address: 104.21.39.17 (US, San Francisco) Hosting org: AS13335 Cloudflare, Inc. Registrar: NameSilo, LLC !!! REGISTRAR INTEGRITY ALERT — NameSilo !!! NameSilo is a registrar documented by PhishDestroy as (1) publicly lying about received abuse reports, (2) shielding a $20M+ Monero-theft operation (xmrwallet.com) for 10 continuous years, and (3) retaliating against PhishDestroy by getting our X/Twitter account @Phish_Destroy banned after we published the evidence. Researchers/victims must ALWAYS CC compliance@icann.org on every abuse ticket — NameSilo has a track record of later claiming reports were never received.

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: 2026-05-06 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-06-15 14:20:41 UTC (by PhishDestroy tracker) First reported: 2026-06-17 21:01:40 UTC (abuse notice filed) Last verified: 2026-06-21 16:20:35 UTC Neutralised: 2026-06-16 00:40:13 UTC Current status: taken down (registrar suspended or DNS dead) ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019ecb39-2b62-744f-9bf3-0dec0c4f1f83/ Wayback Machine: https://web.archive.org/web/*/t-mobile.siydbc.top crt.sh CT logs: https://crt.sh/?q=%25.t-mobile.siydbc.top Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=t-mobile.siydbc.top AlienVault OTX: https://otx.alienvault.com/indicator/domain/t-mobile.siydbc.top URLhaus: https://urlhaus.abuse.ch/host/t-mobile.siydbc.top/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-06-18 16:36:58 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] This domain poses a threat as it impersonates T-Mobile, attempting to deceive users into revealing sensitive information. PhishDestroy identifies that t-mobile.siydbc.top was created on May 06, 2026, and registered through NameSilo, LLC, with 19 out of 95 security vendors on VirusTotal flagging it as malicious. The site's SSL certificate was issued by Let's Encrypt, which may give a false sense of security. The indicators of this threat include its appearance on at least one security blocklist and its resolution to the IP address 104.21.39.17. Given these red flags, users who visited this site should be cautious and monitor their accounts for any suspicious activity. If a user has already visited t-mobile.siydbc.top, they should immediately change their passwords and verify the authenticity of any communications claiming to be from T-Mobile, ensuring they are not disclosed to this potential scam site. ## EVIDENCE HASHES ---------------------------------------------------------------- PhishDestroy Case ID: PD-20260617-88C497 TLS cert SHA-256: 6a36661fd82e59d7bd951552fbcc2c3c77e382ba57ccdd8c366446f9f2301ee1 ## 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. ## CORRECTIONS / APPEALS ---------------------------------------------------------------- Full HTML report: https://phishdestroy.io/domain/t-mobile.siydbc.top/ JSON API: https://api.destroy.tools/v1/check?domain=t-mobile.siydbc.top 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: volunteer-driven open-source threat-intelligence platform.
