HEALTHCARE SECTOR ALERTED TO IMPERSONATION TACTIC
Shared from Health-ISAC to HHS-OIG to the Healthcare Sector
In a matter of only two days, tactical information shared by a member
within the Health-ISAC community became a nationwide alert to the entire
healthcare sector. Public / private partnerships enable Information Sharing
and Analysis Centers (ISACs) like Health-ISAC to move actionable
information quickly.
A Health-ISAC member recently noticed a postcard impersonating HSS with scare tactics claiming to be notices of a mandatory HIPAA compliance risk assessment. The member shared the postcard as well as a list of other network domains used by the scammers. The postcards are laced with scare tactics about HIPAA fines and even state a fabricated deadline and direct the recipient to a website purporting to be the OCR (Office for Civil Rights.)

When this information was shared to the H-ISAC community, the team at the H-ISAC Threat Operations Center notified HC3 (Health Sector Cybersecurity Coordination) who in turn worked with their OIG (Office of Inspector General) within HHS. OCR then issued a nationwide alert to the healthcare sector for awareness and protection from falling for scare tactics of an entity impersonating HHS.
