boostzro[.]us

The domain boostzro.us was registered on May 19, 2026 and currently resolves to the Cloudflare‑owned address 104.21.95.158 located in Canada. The site presents an HTTP 200 response and serves a TLS certificate from Let’s Encrypt (E7). The only visible artifact is the page title “Confirm Your Action”; no further page content has been publicly disclosed. Infrastructure analysis shows a zero‑score trust rating from Gridinsoft (0/100) and that the domain is listed on three security blocklists. Seven of ninety‑two VirusTotal scanners have flagged the site, indicating a moderate detection rate among antivirus engines. The domain appears in one AlienVault OTX pulse and has been blocked by multiple security filtering solutions. Despite these indicators, the site remains active. Defenders should add boostzro.us to URL filtering and DNS sinkhole rules, enforce TLS inspection to capture any payload, and monitor outbound connections to the associated Cloudflare IP. Because the exact phishing payload and targeted brand are not yet disclosed, further investigation of the page content and any submitted credentials is recommended to determine the full scope of the threat.
