Analysis indicates that uj9mc8hbb.cc.rs6.net represents a targeted brand impersonation campaign against Constant Contact. The page title matches the legitimate service exactly, suggesting an attempt to harvest login credentials from users expecting to access email marketing or contact management tools. Infrastructure analysis reveals deployment on rs6.net infrastructure with HSTS enabled, which may lend a false sense of security to visitors. The domain status is currently offline following detection, yet the underlying threat model involves social engineering to capture authentication data.

Technical indicators include a VirusTotal score of 1/95 security vendors flagging the domain, registration through MarkMonitor Inc. with a creation date of February 21, 2026, and presence on 2 blocklists such as PhishDestroy and OISD. Additional metrics show a Gridinsoft trust score of 0/100, SSL certificate issuance by GlobalSign nv-sa, and resolution to the IP address 208.75.122.11 utilizing Apache HTTP Server technology. These elements collectively demonstrate coordinated malicious registration and hosting patterns.

If users have visited this domain, immediate actions include resetting passwords for any Constant Contact or associated accounts, enabling multi-factor authentication where possible, reviewing account activity logs for anomalies, and conducting a full antivirus scan on affected devices. Ongoing vigilance against similar domains registered through the same channels is advised to mitigate future exposure risks. Risk assessment classifies this as elevated due to the impersonation focus and multiple detection signals.
