Hosting org: GitHub, Inc Registrar: GitHub, Inc. Nameservers: NS_NOT_FOUND ## 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: pending notification queue. No abuse reports filed yet — this domain is waiting for the next cycle of our automated abuse-reporter. ## TIMELINE ---------------------------------------------------------------- First detected: 2026-07-12 14:29:19 UTC (by PhishDestroy tracker) Last verified: 2026-07-12 18:00:34 UTC Current status: ACTIVE / observable ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019f564d-4739-7089-b4d0-8df822ed3c59/ Wayback Machine: https://web.archive.org/web/*/tech-master-star.github.io crt.sh CT logs: https://crt.sh/?q=%25.tech-master-star.github.io Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=tech-master-star.github.io AlienVault OTX: https://otx.alienvault.com/indicator/domain/tech-master-star.github.io URLhaus: https://urlhaus.abuse.ch/host/tech-master-star.github.io/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-07-12 17:18:02 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] The domain tech-master-star.github.io is currently listed as a high‑risk generic phishing site. Analysis shows it is hosted on GitHub Pages and resolves to the IPv4 address 185.199.108.153, which belongs to GitHub, Inc. The site presents a Let's Encrypt‑issued certificate (YR2) and is fronted by Varnish and Fastly caching layers. Technical inspection reveals that the infrastructure relies on standard GitHub static‑site hosting. The presence of Varnish and Fastly indicates the use of a CDN cache, which can obscure direct requests to the origin server. No authoritative name servers were identified in the DNS data, and the domain is registered through GitHub, Inc., further confirming the use of the platform’s built‑in registration service. Threat intelligence feeds have flagged the domain on at least two public blocklists, including PhishDestroy and OpenPhish, and VirusTotal reports that 10 of 95 scanned security vendors label the site as malicious. The limited visibility into underlying services and the absence of additional IP addresses or subdomains leaves open the possibility of ancillary infrastructure that has not yet been observed. Defenders should treat traffic to tech-master-star.github.io as hostile. Immediate actions include adding the domain to web‑proxy deny lists, configuring email gateways to quarantine messages that reference the domain, and ensuring that authentication mechanisms such as MFA are enforced to mitigate credential harvesting attempts. Continuous monitoring of the domain’s DNS resolution and any new associated URLs is recommended. Given the active status, high risk rating, and confirmed phishing classification, the threat remains operational. Ongoing collection of samples and regular review of security‑vendor detections will be necessary to track potential evolution of the campaign. [Updates since narrative was generated:] - VirusTotal detections: now 10/95 (narrative was written when count was lower) ## 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. ## CORRECTIONS / APPEALS ---------------------------------------------------------------- Full HTML report: https://phishdestroy.io/domain/tech-master-star.github.io/ JSON API: https://api.destroy.tools/v1/check?domain=tech-master-star.github.io 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: independent open-source threat-intelligence platform.
