165tyesy[.]vercel[.]app

This domain, 165tyesy.vercel.app, is flagged as an active credential harvesting phishing site designed to impersonate the WP Poczta email service. Analysis indicates the site presents a fraudulent login interface mimicking the legitimate WP Poczta platform, a tactic commonly employed to harvest user credentials. The risk level is classified as elevated due to the targeted nature of the campaign and the potential for significant data compromise among Polish-speaking users. Infrastructure analysis reveals the domain resolves to the IP address 216.198.79.3 and is registered through Vercel Inc., a platform frequently exploited for rapid deployment of phishing pages. Detection metrics from VirusTotal indicate that 13 out of 95 security vendors have flagged this domain as malicious, suggesting moderate consensus on its fraudulent nature. The page title, Poczta - Najlepsza Poczta, największe załączniki - WP, directly mirrors the branding of the legitimate WP Poczta service, further corroborating the impersonation attempt. The SSL certificate is issued by Google Trust Services, which, while providing encryption, does not validate the legitimacy of the site’s content or intent. Mitigation steps for this specific threat type include immediate blacklisting of the domain and associated IP address within organizational security policies. Network administrators should implement DNS filtering to block access to 165tyesy.vercel.app and monitor for any attempts to resolve this domain or its IP. End-users should be educated on recognizing phishing indicators, such as discrepancies in domain names (e.g., vercel.app vs. wp.pl) and the absence of multi-factor authentication prompts on login pages. Additionally, security teams are advised to conduct retrospective analysis of network logs to identify any prior interactions with this domain and reset credentials for potentially compromised accounts.
