How to Prevent Business Email Compromise or Imposter Email Threats

Business email compromise

Business email compromise (BEC), also known as imposter email, is an emerging global threat. The FBI estimates that this growing problem has already hit more than 22,000 victims and caused more than $3 billion in losses around the world. (See Public Service Announcement, alert #I-061416-PSA.)

As described in "How to Protect Against Phishing Attacks," one way thieves hack into accounts or get personal information is through social engineering or phishing methods where the thief pretends to be someone or something that they are not. By gaining the confidence of the victim, they simply ask for information which the victim provides.

Imposter emails trick people into sending money or sensitive corporate data. In the typical scenario, the request appears to come from a high ranking executive in the company. The email will include some plausible reason as to why it is not going through the normal channels, and there may be a sense of urgency in the request. Eager to please the boss, the victim complies with the request, and realizes later that it was a scam.

 

The Issue is Similar Domain Names

You may be wondering, how could someone get fooled by an imposter email? After all, didn't they look at the email address from which the request came?

The problem is that attackers may use a domain name that is very similar to a legitimate domain with which the victim typically does business. At a quick glance, it can be very easy to miss an extra letter or number in the domain of an email address.

 

5 Ways to Protect Your Business from Hackers

 

Detecting Phishing Attacks

There are ways to detect probable phishing attacks. Corserva's email security solutions include filtering algorithms that accurately identify and prevent imposter email threats before they reach end users. By creating dynamic policies, you are always protected from attack as policies are updated as quickly as threat tactics. Best of all, there are no static lists to maintain, such as lists of users or domains.

What can make imposter email so difficult to detect is the absence of common signs of a potential threat. Unlike other forms of malicious activity, imposter email usually arrives in low volumes and contains no malware.

To thwart imposter email, Corserva's cybersecurity solutions use a combination of dynamic and algorithmic approaches that include:

  • sender/recipient reputation
  • domain reputation
  • algorithmic analysis
