Cyber criminals are targeting staff by hacking into senior employee's emails and requesting personal data from unassuming employees, according to a computer security company.
This practice, known as business email compromise (BEC) or "CEO fraud", allows cyber criminals to gain access to – or to convincingly replicate – the email address of a senior staff member and then send a mail to a relevant person within the organisation, instructing them to share information or help in making a payment.
In many cases, the instruction may appear to come from the victim’s boss, and may even be written in a similar style that is used by the boss.
Anna Collard, senior vice-president of content strategy for KnowBe4 Africa, a security awareness organisation, said as much as a third of all security incidents are BEC phishing attacks.
"Because they do not request the recipient to click on a link or open an attachment, they seem quite innocuous at first and do not trigger any security scanners or warning signs. However, they cause the largest monetary loss related to cyber crime," said Collard.
According to security vendor GreatHorn’s 2021 BEC Report, 71% of BEC attacks use a spoofed email account or website to establish credibility.
Sixty-nine percent of BEC attacks utilise spear phishing, increasing their chances of reaching the right people within an organisation who have influence over money.
The report cited finance as being the number one target (57% of the time), with CEOs next (22%) and IT third (20%).
Collard said people should reduce the risk of falling prey to cyber criminals by ensuring they have strong and unique passwords on all their email accounts.
"Add another layer such as two-step or multi-factor authentication to your password. Verify any payment requests or change of banking details with the recipient, for example via WhatsApp or a phone call."
