login-pro-com[.]wstd[.]io

This domain, login-pro-com.wstd.io, is identified as a credential theft operation designed to harvest user login credentials through deceptive login portals. Analysis indicates the site mimics legitimate authentication pages to trick users into entering usernames, passwords, and other sensitive information, which is then exfiltrated to attacker-controlled infrastructure. The threat is classified as high-risk due to its direct targeting of user credentials, which can lead to account takeovers, unauthorized access to corporate or personal systems, and subsequent data breaches or financial fraud. Infrastructure analysis reveals multiple indicators of malicious activity. The domain resolves to the IP address 104.19.163.34, hosted on Cloudflare infrastructure (AS13335), a common obfuscation tactic used by threat actors to conceal their true origin. It is flagged by 12 out of 95 security vendors on VirusTotal, including detections for credential phishing. The domain was registered on February 21, 2026, and is already listed on one security blocklist. The SSL certificate, issued by Let's Encrypt (serial number E8), is valid but does not mitigate the underlying malicious intent. Google Safe Browsing has also flagged this domain as phishing, further corroborating its fraudulent nature. Users who have visited login-pro-com.wstd.io or entered credentials on this site should take immediate action to mitigate risk. First, reset passwords for any accounts that may have been exposed, prioritizing email, financial, and work-related credentials. Enable multi-factor authentication (MFA) on all critical accounts to prevent unauthorized access. Monitor accounts for suspicious activity, such as unrecognized logins or transactions, and report any anomalies to the respective service providers. If corporate credentials were entered, notify the organization’s security team to assess potential lateral movement or data exposure risks. Finally, scan the device used to access the site for malware, as credential theft domains may deploy additional payloads to maintain persistence or exfiltrate further data.
