The FBI offers advice and warnings to select partners based on the cyber activity they observer from malicious actors.
Usually, these notices (called "PINs", Private Industry Notifications) are restricted from public distribution; trusted individuals who recieve the PINs can act on the information but not share it. However, the FBI recently released one on Business Email Compromise (BEC) that is allowed to be published, so we are posting it below.
BEC costs businesses in the US over $400 million per year, and grows every year. Complicated phish kits are used to mimic common providers like Google and Microsoft. Remember to turn on two factor authentication on email accounts (official and personal) and verify any suspicious emails by calling the sender.
