mast103.com has been identified as a phishing domain designed to mimic Microsoft Account login pages to steal user credentials. PhishDestroy identifies this domain as a Microsoft Account phishing scam based on its active status and zero detections across 95 VirusTotal scanning engines as of the latest analysis. Technical indicators reveal the domain was registered through NameSilo, LLC on October 07, 2013, and currently resolves to IP address 188.114.96.3. The presence of a Google Trust Services SSL certificate adds superficial legitimacy, which threat actors commonly exploit to deceive visitors. Given the domain's age contradicts its recent malicious activity, users should exercise heightened caution when encountering similar login prompts. The combination of an aged domain, low detection rate, and hosting infrastructure linked to known malicious activity raises significant concerns about its use in credential harvesting campaigns. PhishDestroy's investigation highlights how threat actors leverage legitimate domain registration services and trusted SSL providers to obfuscate phishing operations. While the immediate risk remains unquantified, the lack of antivirus coverage suggests this campaign remains in early stages of deployment. If you visited mast103.com or entered any credentials, immediately change passwords for all Microsoft accounts and enable multi-factor authentication. Scan your device with updated antivirus software and monitor accounts for unauthorized access. Report the domain to your organization's security team or through PhishDestroy's portal to contribute to collective threat intelligence. Exercise extreme caution with unsolicited login prompts and verify sender addresses before interacting with any emails claiming to be from Microsoft.
