Email Security in the Age of COVID
September 8, 2020
The COVID-19 crisis, besides being an immense health crisis, has also introduced a troublesome issue into the technology environment: increased cybercrime.
Since January, sophisticated cybercriminals have leveraged the COVID-19 pandemic to stage an array of cyberattacks, from ransomware takeovers of hospital and healthcare systems to impersonating video conferencing platforms which have soared in usage by remote work-from-home employees (in one 3-week period during April-May alone, 2,449 Zoom-related domains were registered, according to Check Point.)
Malicious Emails Soar
Among the biggest rises in cybercrime related to the pandemic is an attack on emails. Correlating in numbers with a UN report of a 600% increase in malicious emails during the current crisis, our partner Barracuda Networks estimates as well that the increase in the number of coronavirus or COVID-19-related spear-phishing attacks has soared by 667% since the end of February 2020. Google’s Threat Analysis Group also reported in mid-April that they blocked 18 million COVID-19 themed malware and phishing emails per day.
Spear-phishing is the fraudulent practice of sending emails ostensibly from a known or trusted sender for the purpose of inducing targeted recipients to unwittingly reveal confidential information.
The majority of the COVID related phishing emails involved hackers impersonating health organizations such as the World Health Organization to get personal information and/or delivering fake coronavirus-related news. Hackers are also creating fake COVID-19 themed email alerts. Recipients who respond to these phony alerts usually end up downloading malware or otherwise compromising their data security.
Phishing is a serious threat that can cost companies and individuals serious money and peace of mind. What can organizations do to protect themselves and their employees from the increased threat of malicious emails during this time?
No Such Thing as “Too Careful”
Fraudulent emails that seem very authentic on the surface can invariably even catch the most conscientious of us off guard. As a matter of practical and best practice advice, recipients should always be extremely cautious before opening emails or alerts that appear to come from health experts, government agencies or businesses, as well as not downloading or installing programs from sources seemingly familiar sources unless the communications is confirmed as being from the real source, etc.
