Government healthcare agencies, COVID-19 response organizations, and medical research facilities from across the globe were the targets of Business Email Compromise (BEC) phishing campaigns coordinated by multiple Nigerian BEC actors during the last three months.

BEC aka EAC (short for Email Account Compromise) scammers are known for using social engineering via phishing attacks or hacking to switch the bank accounts used by an organization's financial department to wire out funds.
