Coronavirus scam<br />

interfere with the functioning of a<br />

computer. There are also laws against fraud<br />

and the GDPR, which protects data, and this<br />

would come into play because of the data<br />

the hackers obtained illegally. The problem<br />

is that these hackers are difficult to locate,<br />

as they often use technological measures<br />

to ensure that they are not traceable.<br />

WHAT ELSE CAN WE DO ABOUT IT?<br />

This example was located and prevented<br />

through Libraesva's email security software<br />

and management. It was observed that<br />

the spoofed sender of the email was on<br />

a compromise protection list, known<br />

in the industry as 'BEC - Business Email<br />

Compromise', so additional checks were<br />

undertaken.<br />

The email was sent using an email address<br />

of another university, after that person<br />

was successfully hacked. Using Libraesva's<br />

Adaptive Trust Engine's relationship<br />

monitoring, we saw that the trust between<br />

these two universities was quite high. But<br />

the trust between the two individual users<br />

was low; we didn't let the organisational<br />

trust get in the way of understanding the<br />

true nature of the email.<br />

The third indicator was that the email<br />

came externally to the Milan University<br />

users, which doesn't make any sense, as all<br />

emails from the director will 99% of the<br />

time come via the internal route, meaning<br />

this is obviously fake.<br />

The coronavirus is an opportunity for<br />

hackers to take advantage of the fear to<br />

scam people, business and universities. It is<br />

important to be aware of these risks and<br />

take the necessary precautionary action.<br />

Using the above indicators, Libraesva has<br />

built a dedicated technology to halt these<br />

kinds of attacks and make sure your IT team<br />

employ some Email Security, as this is the<br />

main way that threats and malicious activity<br />

can get into your organisation.<br />

EMAIL LANDSCAPE AND THE CORONA VIRUS<br />

Since 17 February, Libraesva have been carefully monitoring the situation with the<br />

Coronavirus and the effect it is having on email, looking into the change of the<br />

email content, the behaviour of users and even the changing threat landscape.<br />

In the top graph, right, supplied by the World Health Organisation, can be seen<br />

the growth of the virus in China and other countries. By paying close attention to<br />

the ‘Other Countries’ graph, it is possible to compare the infection rate to the<br />

second graph, showing the amount of legitimate communication around the virus<br />

in a similar timeframe. When comparing the two data sets, it can be seen that the<br />

curve is almost identical, with the more legitimate communication growing at the<br />

same rate as the infections are. This clearly indicates that the concern and<br />

communication between organisations is effectively rising at the same rate as the<br />

infections are growing.<br />

After looking at the clean email, in comparison to the infections, it's possible to<br />

see how the malicious email and threat attempts are changing, too. The graphic,<br />

bottom right, demonstrates how the malicious attempts on Libraesva users have<br />

increased at the same rate, meaning not only are the threat actors using the<br />

virus to their advantage, but also that end users are discussing the issue more.<br />

One of the key aspects of a successful attack is the degree to which such incidents<br />

are talked about and the anxiety they generate amongst other users - and this is<br />

the perfect example of that happening.<br />

Shown here is the growing communication<br />

taking place, by email, about the Coronavirus.<br />

use the virus to their advantage.<br />
