app31-facebook[.]blogspot[.]com

The domain app31-facebook.blogspot.com is currently active and flagged as a high-risk brand impersonation threat targeting Facebook. Analysis confirms the domain is designed to mimic Facebook login pages, likely for credential harvesting or account compromise. The infrastructure is hosted through a legitimate blogging platform, which may contribute to its persistence and evasion of initial detection mechanisms. Infrastructure analysis reveals the domain resolves to the IP address 142.250.154.132 and is registered through Google Blogger. The SSL certificate is issued by Google Trust Services, providing a false sense of legitimacy. VirusTotal detection metrics indicate that 10 of 95 security vendors have flagged this domain as malicious. No historical registration data is available due to the domain being part of a subdomain structure under a larger platform, which complicates traditional WHOIS-based attribution. The domain remains active as of this report, posing an ongoing risk to users who may mistake it for legitimate Facebook services. Organizations are advised to block this domain at the network perimeter and update endpoint protection rules to include this indicator. Security teams should monitor for related subdomains under the same parent domain (blogspot.com) and educate users on identifying brand impersonation tactics, particularly those leveraging trusted hosting providers. Additional scrutiny of SSL certificates issued to subdomains under blogging platforms may help identify similar threats.
