Common attack techniques plus three practical steps to help minimize risk.
Hackers are busy exploiting coronavirus in their attacks. In recent weeks SophosLabs has seen a surge of COVID- and Corona-related domains registered – while some will be legitimate, it’s a fair bet that the majority are destined for criminal purposes.
Common attack techniques
Phishing attacks using COVID-19 as a lure are the most visible and immediate cybersecurity risk right now. Common tactics include:
Coronavirus news
Beware of emails, SMS, and WhatsApp messages from unknown sources with information on coronavirus. Often hackers impersonate legitimate organizations and people to make their messages more believable.
Home delivery scams
With many people waiting on home delivery of essential items, hackers are impersonating delivery services. Their goal: to trick you into clicking malicious links or con you into paying extra ‘delivery’ fees.
We’re also seeing coronavirus used in other ways, including:
Extortion attempts
Criminals threaten to infect people with coronavirus unless you pay them. Often these threats include a small piece of personal information to make it more believable.
Malicious apps
Purporting to give you useful information on coronavirus, these apps enable the crooks to access all the information on the device – and even hold you to ransom.
Malicious documents
These documents claim to contain coronavirus-related information. Upon opening them you’re asked to ‘enable editing’ and ‘enable content.’ Doing so installs malicious software onto your computer.
Practical steps to minimize risk
In the current situation, many people are lowering their guard to phishing attacks and scams. We’re more anxious, more eager for information, and therefore less likely to question something that could be suspect.
With that in mind, here are three practical steps you can take to minimize the risk from coronavirus-related attacks.
Enable Multi-Factor Authentication (MFA)
MFA is a great form of defense against attacks that use a fake login page to trick people into entering their credentials.
Raise awareness of these scams amongst your employees
A simple, but effective, step is to always looks at the actual email address used to send the email, not just the display name. (If you’re on a mobile device click on the display name to reveal the real email address.)
