New Ransomware attack hits European Banks and Governments and is on its way to the US

 

A new artifact Ransomware dubbed ‘Petya’ or ‘NotPetya’ or ‘GoldenEye’ has started wreaking havoc on bank and government systems in Ukraine, Russia, France and Spain affecting Public and Private institutions around the globe. Companies affected are reported to be high-profile victims like Danish shipping giant Maersk, US pharmaceutical company Merck and more. 

And it is heading to our shores in the US. 

It is vital that you protect your systems from these sorts of targeted attacks. 

Here are 5 ways you can protect you and your company:

  • Anti-Virus Software

    Install a quality Anti-Virus/Anti-Malware solution on all your systems and keep it updated!

     – This involves installing up-to-date Anti-Virus definitions on all critical systems

     – If you have a corporate network, ensure that you have a centrally managed virus 

  • Perform regular backups of critical systems storing the data in a secure offsite location

     – Having backups to your data means not having to pay the ransom to get your data back

     – Verify that your backup can be restored successfully on a regular basis

  • Use due diligence when clicking on e-mails or attachments as well as links

     – One of the bigger attack vectors for receiving a ransomware infection is by clicking on a link in an e-mail or an attachment

      If you suspect something as not being legit do not open it, and contact your support team

  • Patch all your affected systems with regularity, including Third-Party apps like Java and Flash

     – Patching systems on a regular interval is vital to ensuring you are not susceptible to attack

     – Patch your systems as often as production allows to ensure that you have the best defensive posture

  •  To prevent the spread of Malware, if a system is suspected as infected, isolate it immediately

 – If a computer system reports the presence of malware, disconnect the system from the network as quickly as possible to prevent the spread of the infection. 

 – Wipe the system’s hard drive completely and restore the Operating System before returning it the network
