CEO Fraud is a scam in which cybercriminals spoof company email accounts and impersonate executives to try and fool an employee in accounting or HR into executing unauthorized wire transfers, or sending out confidential tax information.
The FBI calls this type of scam "Business Email Compromise" and defines BEC as "a sophisticated scam targeting businesses working with foreign suppliers and/or businesses that regularly perform wire transfer payments. The scam is carried out by compromising legitimate business e-mail accounts through social engineering or computer intrusion techniques to conduct unauthorized transfers of funds."
In the time period from January 2015 to June 2016, the FBI reported a 1300% rise in losses from this type of fraud. Most victims are in the US (all 50 states), but companies in 100 other countries have also reported incidents. While the fraudulent transfers have been sent to 79 countries, most end up in China and Hong Kong. Unless the fraud is spotted within 24 hours, the chances of recovery are small.
Four Attack Methods
Understanding the different attack vectors for this type of crime is key when it comes to prevention. This is how the bad guys do it:
Phishing emails are sent to large numbers of users simultaneously in an attempt to "fish" sensitive information by posing as reputable sources-often with legitimate-looking logos attached. Banks, credit card providers, delivery firms, law enforcement, and the IRS are a few of the common ones. A phishing campaign typically shoots out emails to huge numbers of users. Most of them are to people who don't use that bank, for example, but by sheer weight of numbers, these emails arrive at a certain percentage of likely candidates.
2. Spear Phishing
This is a much more focused form of phishing. The cybercriminal has either studied up on the group or has gleaned data from social media sites to con users. The email generally goes to one person or a small group of people who use that bank or service. Some form of personalization is included - perhaps the person's name, or the name of a client.
3. Executive Whaling
Here, the bad guys target top executives and administrators, typically to siphon off money from accounts or steal confidential data. Personalization and detailed knowledge of the executive and the business are the hallmarks of this type of fraud.
4. Social Engineering
Within a security context, social engineering means the use of psychological manipulation to trick people into divulging confidential information or providing access to funds. The art of social engineering might include mining information from social media sites. LinkedIn, Facebook and other venues provide a wealth of information about organizational personnel. This can include their contact information, connections, friends, ongoing business deals and more.
