3355tt[.]com

This domain, 3355tt.com, is identified as a credential harvesting phishing site targeting users through deceptive login interfaces. Analysis indicates the domain is currently offline, displaying a 502 Bad Gateway error, which may suggest temporary takedown or infrastructure adjustments by the threat actor. No specific brand impersonation has been confirmed, but the domain exhibits characteristics consistent with generic phishing campaigns designed to capture sensitive user credentials, such as usernames, passwords, and potentially multi-factor authentication codes. Infrastructure analysis reveals the domain was registered through Metaregistrar BV on February 21, 2026, an unusually future-dated creation timestamp that may indicate domain spoofing or registry manipulation. It resolves to the IP address 45.138.71.205, hosted on AS35251 (NetLab Global), a network segment frequently associated with malicious activity. The domain is flagged by 17 of 95 security vendors on VirusTotal, and it appears on two security blocklists, including PhishDestroy and PhishingDB. The SSL certificate is issued by Let's Encrypt (serial number E7), a common tactic to lend superficial legitimacy to phishing sites while avoiding certificate costs. Current status indicates the domain is offline, but historical activity and infrastructure patterns suggest it may resurface under a different guise or subdomain. Organizations are advised to block the domain and its associated IP (45.138.71.205) at the network perimeter. Endpoint protection systems should be updated to include this domain in phishing detection rules, and users should be educated on recognizing generic credential harvesting attempts. Security teams should monitor for related domains registered through the same registrar or resolving to the same IP range, as threat actors often reuse infrastructure across campaigns.
