Common ransomware infection

RDP Servers: It is hard to imagine that in today’s IT world there are still many RDP servers that are directly connected on the internet . The reality is internet-connected RDP needs to stop. The fact that over half of ransomware comes in through RDP tells us that exposing RDP to the internet does not align with a forward-thinking ransomware resiliency strategy .


Phish Email: The other most frequent mode of entry is through phish email . We’ve all seen emails that just don’t make sense or look right . The right thing to do is delete that item, but not every user handles these situations the same way . There are popular tools that can assess the threat risk of phish success for an organisation . These tools can be effective in measuring an organisation’s competency in being able to self-assess the risk of phishing emails, attachments and more.

Visiting Infected website: A drive-by download is any download that occurs without your knowledge. Ransomware distributors make use of drive-by downloads by either hosting the malicious content on their own site or, more commonly, injecting it into legitimate websites by exploiting known vulnerabilities. When you visit the infected website, the malicious content analyses your device for specific vulnerabilities and automatically executes the ransomware in the background.  Unlike many other attack vectors, drive-by downloads don’t require any input from the user. You don’t have to click on anything, you don’t have to install anything and you don’t have to open a malicious attachment – visiting an infected website is all it takes to become infected.
