FBI Warns Businesses of BEC Scams

FBI Warns Business of BEC Scams - Dynamic Quest

The FBI has issued alerts to all businesses about the spread of BEC scams.

Business Email Compromise schemes, or BEC scams, have grown by more than 270{61194e7afa0946242429d3457858805d5d8e9f1e3c2fa6ff4cb841084e122ca3} since the beginning of last year according to the FBI. At their last reporting, more than 7,000 businesses have lost more than $1.2 billion in just two years.

Luckily, this sort of an indiscriminate and devastating fraud can be combated with IT risk management. Such services monitor, assess, and evaluate threats to your network no matter where they come from, giving you the peace of mind to concentrate on your business itself.

On the facade, BEC scams seem less impressive than thefts perpetrated by sophisticated malware that target banks and other large institutions. However, BEC attacks can avoid the basic security steps taken by both businesses and individuals, making them more versatile, and more vicious.

A BEC scam targets people instead of machines, using more conventional methods of deception. In short, criminals convince their victims to hand company money over to them directly, and so far, they’ve been very successful. The FBI warms that “[t]he scam has been reported in all 50 states and in 79 countries. Fraudulent transfers have been reported going to 72 countries; however, the majority of the transfers are going to Asian banks located within China and Hong Kong.”

Criminals perpetrate BEC scams in two stages. The first phase, reconnaissance, involves a traditional email phishing scam. Once the criminals have access to an employee’s email account, they monitor the account for an extended period of time, sometimes up to several months. During this time, they familiarize themselves with the financial processes of the target business. They learn if wire transfers are used, who initiates them, and who typically requests them. They search emails for key terms like invoice, deposit, president, and transfer.  The fraudsters study the target business’ activities, organizational relationships, interests, travel, and purchasing plans—anything that might give them an inside advantage.

The second phase of the fraud comes in two versions. The first is known as a CEO Phishing Scam. Crooks create a domain name that is nearly identical to the company’s, and send a spoof email that appears to be from the CEO or other high-ranking executive. This email will appear completely legitimate, and only a careful reading will give the targeted employee a chance of detecting something “phishy.” The impersonator requests a monetary transfer, and if the employee remains oblivious to the scam, she carries out the instructions. The time and effort spent on the reconnaissance phase often allows the criminals to create an utterly convincing fund request. Before anyone realizes what has happened, the company money is out the door.

In the other iteration of phase two, criminals take over the email of someone within the targeted company who is responsible for billing and invoicing. They use that account to send out seemingly legitimate invoices, instructing wire payments to a newly designated bank account. Again, it would take intense scrutiny to notice anything wrong with the phony invoice.

Spam traps are very unlikely to catch BEC scams as the latter are targeted attacks and not mass emails. These nefarious scams continue to evolve as time goes by, so it is important to be vigilant.  The FBI has urged businesses to adopt the following processes to protect themselves:

  • Create intrusion detection system rules that flag e-mails with extensions similar to company e-mail. For example, legitimate e-mail of .com would flag a fraudulent e-mail of abc-company.com.
  • Register all company domains that are slightly different than the actual company domain.
  • Verify changes in vendor payment location by adding additional two-factor authentication, such as a secondary sign-off by company personnel.
  • Confirm requests for transfers of funds. When using phone verification as part of the two-factor authentication, use previously known numbers, not the numbers provided in the e-mail request.
  • Know the detailed habits of your customers, such as the reasons behind them and amount of said payments.
  • Carefully scrutinize all e-mail requests for transfer of funds to determine if the requests are out of the ordinary.
