Cyber-attacks increased during lockdown – How to safeguard business email

Unfortunately, this has also become a time for online scammers to target businesses and individuals.

Business Email Compromise (BEC) – What you need to know


Business Email Compromise (BEC) attacks are the most costly form of cybercrime, costing US companies considerably more than crimes like ransomware attacks and data breaches.


In fact, BEC attacks cost companies $1.7 billion accounting for half of all the cybercrime losses during 2019 according to insurance firm AIG.


BEC attacks have been around for years but continue to grow in sophistication from the early days that involved hacking and spoofing accounts of CEOs and CFOs.


Most attacks now rely on social engineering aimed at customers, HR departments, suppliers, related accountants, and law firms, and even tax authorities.

Lockdown and BEC attacks


BEC attacks have also evolved from simply trying to transfer funds to fraudulently gift cards, divert tax returns, and even transfer millions of dollars' worth of hardware and equipment into the control of criminals.


Unfortunately, criminals love to make use of major current events to launch their attacks. COVID-19 is just the latest example of a significant event that has been weaponised by cybercriminals to try and profit.


Check Point Research reported that the first two weeks of May saw a 30% increase in COVID-19 related cyber-attacks. About 192 000 coronavirus related attacks were seen per week on average.
