Coronavirus COVID-19 makes the world fall into a hard time, everyone are trying their best to stay up-to-date in their businesses due to most of the organisations are implementing Work from home scheme. However, hackers have created new attacks based on the intense public interest in this pandemic.
One of the most common of these attacks is an email impersonation attack. In this attack, the criminal impersonates organisations like the UN World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC) to trick users into opening a malicious email. Multiple government organisations have issued warnings against these attacks.
Email scams always follow the headlines
Most of these scams are designed to do some variation of the following:
- Infect the user device and spread malware
- Steal login credentials by way of a phishing site or other phishing mechanism
- Collect donations for fake charities through malicious websites
The current pandemic has given scammers all those opportunities and more:
- Selling counterfeit versions of medical supplies that are in short supply
- Tricking users into buying fake cures
- Offering investment opportunities in companies claiming to have the cure
Spreading the infection
There has been a real surge in the registration of new domains that use the word ‘coronavirus.’ Some of these will be put to a good use, but many will be used by hackers for malicious purposes. These malicious websites might appear to offer news or advice on coronavirus outbreak but are being used for phishing or to spread malware. Email impersonation scams often include links to this type of site.
Email impersonation attacks
Over the past few weeks, a number of attacks impersonating the World Health Organisation. These phishing emails appear to come from WHO with information on Coronavirus COVID-19. They often use domain spoofing tactics to trick users into thinking these messages are legitimate.
These email impersonation attacks will include a link in the body of the email. Users who click on that link are taken to a newly registered phishing website.
Remote work and increased risk
As a preventative measure against the spread of Coronavirus COVID-19, many organisations are asking employees to work remotely from home until further notice. These remote workers may rely on email for communication with other employees as well as updates on workplace location and other issues related to the outbreak. This puts users in a state of expectation for email messages from HR or upper management on the subject of the virus. This expectation creates an increased risk for the company because the user is more likely to accidentally open a malicious email if they are expecting a similar legitimate message.
These factors, combined with the diminished ability to confirm the legitimacy of an email due to remote working is a perfect environment for email scams.
Protecting your organisation and employees
There are several ways to protect your company and employees from email scams, and they are based on employee education and security technology:
- Don’t click on links in email from sources you do not know; they may lead to malicious websites
- Beware of emails claiming to be from the CDC or WHO. Go directly to their websites for the latest information.
- Pay special attention to email messages from internal departments or executives who sent regular updates on the outbreak. Domain and display name spoofing are some of the most common techniques used.
- Never give personal information or login details in response to an email request. This is how a phishing attack leads to business email compromise.
- All malicious emails and attacks should be immediately reported to IT departments for investigation and remediation.
- Ensure that your organisation has reliable virus, malware, and anti-phishing protection.
- Make sure employees receive up-to-date training on the latest phishing and social-engineering attacks.
