170tyesy[.]vercel[.]app

This domain, 170tyesy.vercel.app, operates as a credential harvesting phishing site designed to mimic the legitimate WP Poczta email service. The page displays a fraudulent login interface with the title 'Poczta - Najlepsza Poczta, największe załączniki - WP,' tricking users into entering sensitive account details. Once submitted, credentials are transmitted to threat actors, enabling unauthorized access to email accounts, financial data, or other linked services. The impersonation of a trusted email provider increases the likelihood of successful compromise, particularly among users expecting legitimate communication from WP Poczta. Analysis indicates this domain is hosted on infrastructure managed by Vercel Inc., a platform commonly used for both legitimate and malicious purposes. The site resolves to the IP address 216.198.79.195 and employs an SSL certificate issued by Google Trust Services, which may lend a false sense of security to unsuspecting visitors. As of the latest assessment, 12 out of 95 security vendors on VirusTotal have flagged this domain as malicious, categorizing it under generic phishing. The combination of a recognizable brand impersonation, active SSL encryption, and low initial detection rates underscores the elevated risk posed by this campaign. Users who have visited 170tyesy.vercel.app or entered credentials on the site should immediately take corrective action. First, change passwords for the affected WP Poczta account and any other services where the same credentials may have been reused. Enable multi-factor authentication (MFA) on all critical accounts to mitigate further risk. Monitor the compromised account for signs of unauthorized activity, such as sent emails, password reset requests, or unfamiliar logins. If financial or sensitive personal information was accessed, consider reporting the incident to relevant authorities or identity protection services. Organizations should block the domain and associated IP (216.198.79.195) at the network level to prevent further exposure.
