What can you do to avoid being a ransomware victim?


As dangerous as ransomware is, simply being aware and staying updated with the latest ransomware trends can go a long way in securing your data and systems. Here are helpful tips on how you can defend yourself from a likely attack.


Scrutinize emails & its attachments before opening them


Be wary of emails from unverified sources. You can check by communicating directly with the purported sender to confirm if they sent the messages. To check its validity, you can use SecneurX Sandbox to verify the sanity of the email.


Avoid clicking embedded links found in unverified emails


Such social engineering tricks can lead to the download of ransomware. Additionally, be wary of sites that prompt you to enter a CAPTCHA code as this could be linked to a ransomware attack. To check its validity, you can use services like SecneurX Sandbox to verify the reputation of the site.


Back up your important files


While prevention is always better than the cure, having a backup of important files can at least lessen the potential damage done by a ransomware attack. While being locked out of your own system is always a bad thing, at least it's not a total disaster since you can always retrieve your important files. The 3-2-1 backup rule applies here—three backup copies of your data on two different media, and one of those copies in a separate location


Regularly update software, programs, applications


Updating them to the latest versions can provide an added layer of protection against online threats as some ransomware arrive via vulnerability exploits.


Use a layered protection suite


Doing so can detect threats before they enter your network. Security solutions like SecneurX ATP can block Infectious files (like executables (.exe, .run, etc.), archives (ZIP, RAR, etc.), Microsoft Office and PDF documents, JavaScript, and so on) by scanning them at the point of entry of the organisations (File uploads, USB file transfers etc)
