amz36rd[.]s3[.]us-east-1[.]amazonaws[.]com

This domain is flagged as a high-risk credential theft operation impersonating Amazon infrastructure to harvest user login credentials. Analysis indicates the threat actor leverages legitimate cloud hosting services to bypass initial scrutiny while executing targeted phishing campaigns. The domain exhibits characteristics consistent with large-scale credential harvesting, including the use of a trusted SSL certificate and a hosting provider commonly abused for phishing. Infrastructure analysis reveals the following technical indicators: the domain amz36rd.s3.us-east-1.amazonaws.com is registered through Amazon AWS and resolves to the IP address 52.217.142.138. The SSL certificate is issued by Amazon RSA 2048 M04, a legitimate provider, which may aid in evading detection by less sophisticated security controls. The domain was created on May 28, 2026, an anomalous future date suggesting potential manipulation of registration metadata or a placeholder entry. It is currently active and appears on two security blocklists, while VirusTotal reports 5 out of 95 security vendors flagging the domain as malicious. Organizations and users are advised to implement the following mitigation measures to counter this credential theft threat. First, block the domain and its resolving IP address (52.217.142.138) at the network perimeter, including firewalls, proxies, and DNS filters. Second, deploy email filtering rules to quarantine messages containing links to the domain or its subdirectories, as these are likely delivery vectors for phishing attempts. Third, enable multi-factor authentication (MFA) for all accounts associated with the impersonated brand to mitigate the impact of stolen credentials. Finally, conduct user awareness training focusing on identifying cloud-hosted phishing domains, particularly those mimicking legitimate storage or hosting URLs, and report any suspicious activity to internal security teams for further investigation.
