173tyesy[.]vercel[.]app

This domain, 173tyesy.vercel.app, is flagged as a generic phishing site targeting users of a major email service provider. Analysis of the page title, "Poczta - Najlepsza Poczta, największe załączniki - WP," indicates an attempt to impersonate the legitimate webmail portal of a well-known Polish provider, likely aiming to harvest credentials or distribute malicious payloads. No specific drainer kit signatures have been identified, but the domain exhibits characteristics consistent with credential theft campaigns. Infrastructure analysis reveals the following technical indicators: the domain is detected by 14 out of 95 security vendors on VirusTotal, suggesting moderate confidence in its malicious nature. It resolves to the IP address 64.29.17.3 and is registered through Vercel Inc., a platform commonly abused for hosting phishing pages due to its free and ephemeral deployment capabilities. The SSL certificate is issued by Google Trust Services, which, while legitimate, does not mitigate the domain's malicious intent. No creation date is available, but the domain remains active and unlisted on Google Safe Browsing (GSB) at the time of this report. Blocklist monitoring indicates limited propagation, with no additional entries beyond the VirusTotal detections. Current status of 173tyesy.vercel.app is active, with no takedown actions observed. The risk level is classified as elevated due to the domain's operational state and its targeting of a widely used email service. Response actions should include immediate blacklisting at the network perimeter, particularly for endpoints accessing Polish-language services. Organizations are advised to monitor for authentication attempts originating from this domain and to conduct retrospective analysis of logs for prior interactions. Users should be alerted to verify the authenticity of any email portal before entering credentials, especially if redirected from unexpected sources. Despite the moderate detection rate, the domain's persistence and brand impersonation warrant continued vigilance.
