BEC Attacks on the C-Suite Dropped 37% in Q1

New research shows attackers are targeting and establishing relationships with accounts payable departments.

Business email compromise (BEC) attacks increasingly are targeting accounts payable departments and attempting to establish trust via email exchanges before launching an attack.

Ken Liao, vice president of marketing at Abnormal Security, says people who work in finance or accounts payable often don't know every vendor – many companies have hundreds, even thousands of vendors and suppliers.

"The AP people are lower in the organization, but they still have the ability to make large payments," Liao says. "The criminals impersonate the vendor by folding into the natural workflow."

The numbers don't lie: In a report released today, Abnormal Security saw a 28% increase in the size and frequency of BEC attacks over the fourth quarter of 2019 and a 17% increase in large campaigns aimed at 10 or more recipients. Individual BEC attacks targeting the C-suite dropped by 37%.

According to the report, BEC attackers maintain a targeted approach, but strategically group victims to gain social validity and increase the chances of engagement. When cybercriminals "engage" a victim, they typically don't go for the money in the first email. They slowly create trust by simply asking for a form, or a small piece of information that appears like a legitimate request.

"If an attacker goes after an AP person in a way that fits the role of their job, the victim has no reason to doubt," says Chris Hadnagy, CEO of Social-Engineer LLC. "The BEC attackers have stopped going for the large C-suite players because the media covers it so much and people are aware of those attacks. Plus, people are working from home and they are under a lot of stress from all the news of riots, protest, and the pandemic. Their kids are home and they aren't exercising as much, all of this is just creates an environment for hackers to prey on."

Any way it's sliced, BEC attacks remain a profitable avenue for cybercriminals. The FBI reported in February that BECs accounted for roughly 50% of the $3.5 billion in cybercrime losses in 2019. Some of the more prolific BEC cases include that of Toyota, which lost $37 million, and Nikkei, which lost $29 million.

Hadnagy says along with education and awareness campaigns, companies should consider two approaches to help stem the tide of BECs. First, accounts payable people should slow things down: double-check invoices and whether they are legitimate. Second, C-suite people must empower these employees so they feel comfortable asking about a vendor.

"A lot of times companies will go after the person who made the mistake and fire them, but what I tell them is the problem wasn't the AP person, it was the C-suite," Hadnagy says. "Many companies don't have a way for people to verify if an invoice is legitimate."

It would have been much more useful to describe what BEC is and how the compromise happens.
Wow. BEC sounds bad. Too bad the article never defines it or explains how the email compromise happens.
