Analysis indicates the site impersonates Outlook Web Access login pages to harvest corporate email credentials, enabling subsequent business email compromise or lateral movement within victim networks. The threat type aligns with known phishing campaigns exploiting cloud service trust to bypass security awareness controls. Infrastructure analysis reveals multiple high-confidence indicators: the domain verificacionhtmloutlk365.zya.me was registered through Porkbun LLC on September 1, 2021, and currently resolves to IP 185.27.134.128 (GB, AS34119 Wildcard UK Limited). VirusTotal detection shows 3/95 security vendors flagging the domain, while it appears on two security blocklists including PhishDestroy and OpenPhish. The SSL certificate is issued by ZeroSSL GmbH (ZeroSSL ECC DV SSL CA 2), a common provider for short-lived phishing domains. Despite its 2021 creation date, the domain maintains active status with persistent malicious infrastructure. Mitigation requires immediate action from enterprise security teams. Network-level blocking should be implemented for the domain and its resolving IP 185.27.134.128 at firewall and proxy layers. Security awareness training should emphasize verification of URL structures in email links, particularly for cloud service logins. Organizations using Microsoft 365 should enforce conditional access policies requiring multi-factor authentication for all external access attempts. Email security gateways should be configured to quarantine messages containing this domain or similar patterns (verificacion*outlk365). Endpoint protection should monitor for credential harvesting attempts from this infrastructure, with particular attention to browser-based credential managers.
