mout07aprmain[.]wasmer[.]app

This domain, mout07aprmain.wasmer.app, operates as a credential harvesting platform specifically designed to mimic Microsoft 365 authentication portals. Analysis of the infrastructure reveals targeted collection of corporate login credentials, likely intended for subsequent unauthorized access to cloud-based email systems, document storage, or enterprise applications. The domain employs realistic Microsoft branding elements and login interfaces to deceive users into submitting valid credentials, which are then transmitted to attacker-controlled servers for exploitation or resale on underground markets. Evidence supporting this assessment includes multiple technical indicators. The domain was registered on April 24, 2026, through Squarespace Domains II LLC, and currently resolves to IP address 62.210.172.162 located in France. Security systems have flagged this infrastructure extensively: Google Safe Browsing identifies it as phishing, PhishDestroy blocks access to the domain, and 23 out of 95 security vendors on VirusTotal detect malicious activity. Additionally, the domain appears on one security blocklist, and its Let's Encrypt SSL certificate (serial number E7) provides HTTPS encryption to enhance the appearance of legitimacy while facilitating credential interception. Users who may have visited mout07aprmain.wasmer.app should immediately take corrective actions. First, reset any credentials entered on the site, particularly Microsoft 365 or organizational login details. Enable multi-factor authentication on all accounts where possible to prevent unauthorized access. Monitor account activity for suspicious logins, unusual email forwarding rules, or unauthorized application installations. Organizations should review authentication logs for connections originating from the domain's IP address (62.210.172.162) or related infrastructure. If corporate credentials were exposed, initiate incident response procedures to contain potential data breaches or lateral movement within the network.
