Protect against ransomware with email security

28/06/2017 22:38

As the world is gets over one large-scale cyber-attack, it seems another is just around the corner. Over the past few months, millions around the globe have lost money and valuable data to these ransomware crimes.

Although ransomware can spread in many ways, one big culprit is through emails. It is estimated that 65% of all ransomware attacks happen through phishing emails. These kinds of messages don’t necessarily come lit up with banners to announce it’s going to harm your computer.

Email-bourne threats are usually hidden in un-suspecting links that, when clicked, install dangerous files onto your systems that can lock, and even destroy your data.

Ransomware and other malware isn’t the only threat that can harm your system. According to a survey by the SANS institute, spear-phishing attacks are increasing dramatically, this is when cyber-criminals get extremely cunning. Their tactic is to duplicate trusted email addresses and over the space of months, gradually coax out private information from an unsuspecting target.

Ransomware still holds the title as number one for most significant attack, but spear-fishing has become a close seccond.


This form of social engineering gathers enough information from the victim to eventually ask for money or have them transfer a large sum to a fake account that the attacker has access to.


Because of these emerging ways of social engineering and spear-phishing, it is becoming increasingly difficult to detect all bad emails. Some aren’t bad emails- just bad people sending the messages.


Email Security- are you doing it wrong? 

Email is the number one choice of criminals to start an attack, whether they are embedding a ransomware attack or using an imposter email address. Whilst more businesses do have some sort of email security solution, in many cases, it’s not effective enough.


Here are five points to consider when looking for an email security solution:

1.       Look for an email security programme that can integrate with your sandbox.

2.       You need to have granular administrative control over settings.

3.       Anti-spoofing is essential. These mechanisms use authentication methods such as DKIM, SPF and DMARC.

4.       It needs to have encryption capabilities for outbound protection.

5.       Most importantly, the solution needs to align and work with your network security for a seamless solution that works together as one big unit.
