rastreiopac[.]com

Analysis of rastreiopac.com shows a freshly registered domain (created 28 April 2026) that hosts a page titled “Correios - Atualizar Cadastro”. The title mirrors the Brazilian postal service’s account‑update portal, indicating an attempt to lure users into submitting personal data. The site serves over HTTPS with a Let’s Encrypt R13 certificate, and the initial request returns an HTTP 307 redirect, a technique often used to hide the final malicious landing page.

Infrastructure inspection reveals the domain resolves to 179.0.178.168, an address located in Brazil and owned by Master DA Web Datacenter Ltda. Nameserver records point to atrustname.com infrastructure (ares.trustname.com, zeus.trustname.com), which is also listed as the registrar (Fewmoretaps OU d/b/a Trustname.com). The host carries a Gridinsoft trust score of 0 / 100 and has been flagged by VirusTotal, with 1 of 95 scanners marking the domain as malicious. AlienVault OTX includes the domain in a single threat pulse, and it appears on one external blocklist. PhishDestroy has already blocked the site, but the current status remains active, suggesting the operator may be rotating hosting or employing evasion tactics.

Defenders should treat any communication referencing Correios account updates from this domain as malicious. Email gateways and web proxies ought to block traffic to rastreiopac.com and its associated IP address. Incident responders should monitor for credential‑theft attempts, especially submissions of personal identification numbers or payment details. Continuous monitoring of the atrustname.com name‑server range is advised, as the same infrastructure may be reused for additional campaigns. Updating threat intelligence feeds with the listed indicators will help downstream security tools to enforce preventative controls.
