sf[.]tumee[.]com

The domain sf.tumee.com is currently flagged as an active high-risk phishing site specializing in credential theft through brand impersonation. Analysis indicates the domain mimics the login interface of Salesforce, a widely used customer relationship management platform, as evidenced by the page title 'Login | Salesforce.' This tactic is designed to deceive users into entering sensitive authentication details, which are then harvested by threat actors. Infrastructure analysis reveals the domain was registered through NAMECHEAP INC on September 09, 2007, though recent malicious activity suggests potential compromise or repurposing. The domain resolves to the IP address 104.18.8.67, a Cloudflare-associated endpoint that may obscure the true origin of the phishing infrastructure. Detection metrics show that 4 of 95 security vendors on VirusTotal have flagged sf.tumee.com as malicious, a relatively low but notable detection rate that may indicate evasion techniques or recent deployment. The SSL certificate is issued by Google Trust Services, providing a superficial layer of legitimacy to unsuspecting users. As of the latest assessment, sf.tumee.com remains active and poses a significant risk to individuals and organizations utilizing Salesforce services. Immediate action is recommended: users should avoid interacting with the domain and report it to their security teams for inclusion in blocklists. Organizations are advised to implement network-level filtering to prevent access to this IP and domain, while end-users should verify the authenticity of login portals through official channels. Security teams should monitor for credential exposure and consider forced password resets for accounts that may have been compromised through this phishing campaign.
