Reduce Instances of Covid-19 Phishing Email Attacks
The Covid-19 pandemic has created an unlimited supply of news and topics for cybercriminals to utilise in their attacks, as well as major organisations to spoof. Learn what your organisation can do to combat these timely threats.
In my previous post, I focused on how the report we commissioned Ostermann Research to conduct showed the challenges with ransomware and phishing. For this article I would like to focus on a different area of the report which covered the affects of the Covid-19 pandemic on phishing.
Phishing has been a regularly used threat by malicious actors for many years. Prior to the global Covid-19 pandemic, actors used the latest news topics and events in their attacks. We saw phishing emails based on the Olympics, election cycles, disasters, and other news. However, these were transitory and only allowed the cybercriminals to utilise the information for a short period of time. The pandemic has created them an unlimited supply of news and topics to utilise in their attacks. Examples are:
- ⁃Infection numbers
- ⁃Death tolls
- ⁃Work from home information
- ⁃Vaccination information
Since all of these were constantly changing with new information coming out on a daily basis, the malicious actors had the ability to use this information to better target their victims. The other aspect was their ability to spoof many of the major organisations dealing with the pandemic, like the WHO, UNESCO, the USA CDC, and many of the pharmaceutical manufacturers which violated the trust factor many people had with these organisations. We saw spam, phishing emails, business email compromise (BEC), drive-by downloads, and other threats all utilising Covid related themes in their attacks. Many of these attacks target employees in attempts to gain access to the corporate network. When the pandemic hit, many employees shifted to working from home, yet the attacks didn’t diminish. Many organisations struggled (and still do) to secure their employee’s home environment.
As the Osterman research shows:
“72% of organisations believed they lack effectiveness at securing employees’ home infrastructure and preventing it from being a conduit for cyberattacks into the corporate network.” This shows that after over 1 year of dispersed workforce, organisations still don’t feel confident in remote work security. This makes me wonder if we were to experience another pandemic situation, would we be better prepared?
The report also mentions the Threat Forecast, which predicts the following:
- ⁃Phishing Continues
- ⁃Ransomware Intensifies
- ⁃Targeted & timed for maximum (devastating) effect
We’ve also released an article that discusses the post pandemic security landscape that can help you understand what may come next. Suffice to say, organisations will continue to be targeted with phishing and other related threats that use the latest news, events, disasters, etc. To combat these threats, organisations can do the following:
- Implement an organisation-wide security awareness program that regularly trains and educates all employees of phishing and other threats.
- Revisit their email and web security solutions to ensure they are using the latest iterations and have enabled many of the advanced detection technologies that can detect phishing threats
- Implement strong account credential protection including multi-factor authentication to protect stolen account credentials via phishing
