Is the Affordable Health Care Website Secure? Probably not.

This report passively reviews the healthcare.gov site and identifies security weaknesses: username enumeration through differentiated login responses, lack of CAPTCHA or automation mitigations, exposed developer comments revealing internal variables, and potential use of a CKEditor instance with known issues. The author did not perform intrusive testing or exploitation but warns these findings could enable brute-force, account enumeration, or further targeted attacks against a large user base.
