At my last job the traffic was filtered through a proxy due to FINRA regulations. I’d see Portuguese ads for diabetes medication and there were 2 Brazilian guys in the office.
HIPAA only keeps healthcare providers from sharing your information. It's not an omnibus shield for your health information. If Alice tells her coworker Bob that she had diabetes, it's not a HIPAA violation for Bob to tell Charlie.
Are Bob and/or Charlie the name of a person or of a company?
How you're using it, it sounds like Bob or Charlie in your mind is a person. I might be wrong in interpreting it that way. If so could you give another example where Bob and Charlie are companies and the information of Alice is part of a transaction.
Seemed like a major HIPAA violation to me.
