myfciusaumuvuwxteam[.]saystudio[.]net

This domain, myfciusaumuvuwxteam.saystudio.net, poses a direct threat to Facebook users by impersonating the platform's login interface to harvest credentials. Visitors to this site are presented with a fraudulent Facebook page designed to trick them into entering their usernames and passwords, which are then captured by threat actors. The site's infrastructure and content are engineered to mimic legitimate Facebook properties, increasing the likelihood of successful deception, particularly among users who may not scrutinize domain names or SSL certificate details closely. Analysis indicates this domain is a confirmed credential theft operation. It was flagged by 18 out of 95 security vendors on VirusTotal, a significant indicator of malicious intent. The domain was registered on March 07, 2026, through PDR Ltd. d/b/a PublicDomainRegistry.com, a registrar frequently associated with abusive domains. Infrastructure analysis reveals the site resolved to the IP address 94.199.205.30, hosted on AS42807 (CIZGI TELEKOMUNIKASYON ANONIM SIRKETI) in Turkey. The SSL certificate, issued by Let's Encrypt (R13), was likely used to lend an air of legitimacy to the fraudulent page. The domain's page title was explicitly set to 'Facebook,' further reinforcing its impersonation tactics. Users who visited this domain should take immediate action to mitigate potential risks. First, assume any credentials entered on this site have been compromised and change the affected Facebook password immediately. Enable multi-factor authentication (MFA) on the account to add an additional layer of security. Review the account for unauthorized activity, such as unrecognized logins, posts, or messages sent from the account. If financial or sensitive personal information was entered, monitor linked accounts (e.g., email, banking) for suspicious activity. Additionally, scan the device used to access the site for malware, as credential theft sites may deploy additional payloads. Finally, report the incident to Facebook's security team to assist in their efforts to protect other users from similar threats.
