Online scams are nothing new. But as email has evolved and improved, so have scammers and the messages they send. Nefarious emails, attachments and links now appear sophisticated and look legitimate, sometimes tricking even the most meticulous user.

Billions Lost to Business Email Compromise

Over the last three years, organizations all over the world have lost a collective $26B to a very specific type of email scam – Business Email Compromise, or BEC. Recently, a BEC scheme in Spain was brought down, but not before taking over €10M. A scammer in Canada impersonated a contractor and fooled city employees out of over $1M. And the FBI is investigating a network of over 80 people across multiple countries in an attempt to use a BEC plot to steal $46M.

BEC emails are advanced phishing scams, and they’re on the rise. But what makes a BEC attack so dangerous, and so effective?

BEC Scams are Highly Targeted

Scammers aren’t blasting thousands of the same email. They’ve done the research, monitoring the company’s website and social pages. They find the appropriate target, and groom them by sending multiple conversational emails, establishing trust.

They Contain No Malware

Unlike the old style of phishing, where users are told to click on a link, BEC emails have no spammy links. This means they can sometimes evade spam filters, and the end user doesn’t see any red flags.

They Exploit Human Nature

BEC emails imitate an actual person, complete with real-looking email addresses, formatting, company names, and titles. The victim has unknowingly been emailing back and forth with the scammer and trusts that they are who they claim to be. So when asked to send bank information, for example, the victim assumes the request is authentic and complies.

They are Often Under-reported

Victims often don’t realize they made a mistake until much later. And even upon realization, many companies don’t report the incident for fear of damaging their reputation with their customers. Not reporting such incidents allows perpetrators to simply move on to their next victim.
