This domain, 5064334288.dojiner.at, poses a high-risk credential harvesting threat by impersonating the Steam gaming platform. The site displays a fraudulent 'Sign In' page designed to deceive users into entering their account credentials, which are then captured by threat actors. Analysis indicates the domain specifically targets Steam users, leveraging brand familiarity to increase the likelihood of successful compromise. The page title 'Sign In' and the visual design closely mimic legitimate Steam login portals, making it difficult for users to distinguish between the authentic and malicious sites. Infrastructure analysis reveals multiple technical indicators confirming the domain's malicious nature. The domain was registered on February 21, 2026, through the registrar AS214351, and resolves to the IP address 62.60.226.105, located in Germany under the autonomous system AS214351 (FEMO IT SOLUTIONS LIMITED). Security vendor detections on VirusTotal report 23 out of 95 engines flagging the domain as malicious, with Google Safe Browsing explicitly classifying it as phishing. Additionally, the domain appears on one security blocklist, and its SSL certificate, issued by Let's Encrypt (R12), is commonly exploited in phishing campaigns to create a false sense of security. Users who may have visited 5064334288.dojiner.at should take immediate action to mitigate potential compromise. First, reset the password for the Steam account and any other accounts where the same credentials may have been reused. Enable multi-factor authentication (MFA) on all critical accounts to add an additional layer of security. Monitor the Steam account for unauthorized transactions, game purchases, or changes to account settings. If financial information was entered, contact the relevant financial institution to report potential fraud and request a review of recent transactions. Finally, scan the device used to access the site with updated security software to detect and remove any malware that may have been installed.
