185tyesy[.]vercel[.]app

This domain, 185tyesy.vercel.app, is flagged as an active credential harvesting phishing site designed to impersonate the WP Mail webmail service. Analysis indicates a targeted campaign aimed at Polish-speaking users, as evidenced by the page title 'Poczta - Najlepsza Poczta, największe załączniki - WP,' which directly mimics the legitimate WP Poczta interface. The threat type is classified as credential theft through phishing, with an elevated risk level due to its active status and specific targeting of email account credentials. Infrastructure analysis reveals the following technical indicators: the domain is hosted on Vercel Inc. infrastructure and resolves to the IP address 216.198.79.67. Security vendor detections on VirusTotal report 11 out of 95 engines flagging the domain as malicious, indicating moderate but concerning consensus among detection systems. The SSL certificate is issued by Google Trust Services, which, while not inherently malicious, provides a false sense of security to potential victims. No specific creation date is provided, but the active status and detection counts suggest recent deployment. The domain is not yet widely listed on major blocklists, which may contribute to its current effectiveness in evading automated defenses. Mitigation steps for this specific threat type include immediate blocking of the domain and its resolving IP address (216.198.79.67) at the network perimeter. Organizations should deploy email filtering rules to quarantine messages containing links to 185tyesy.vercel.app or its associated infrastructure. End-user education should emphasize the risks of credential harvesting through phishing, particularly for webmail services, and encourage verification of domain authenticity before entering login credentials. Security teams are advised to monitor for indicators of compromise, such as unusual login attempts or access from the resolving IP, and to implement multi-factor authentication to mitigate the impact of credential theft.
