WannaCry Ransomware Attack – What can you do?

As you probably have heard by now, the world is under attack from malicious ransomware, software that enters a computer and encrypts your data demanding a ransom for the unlock key.

What can you do to protect yourself?

Keep your machine updated with the latest Microsoft security patches. 

The Griffin Networks multi-pronged maintenance program is designed to identify issues threatening your network and prevent costly disasters and downtime. You can rest assured that your business systems are being closely monitored with technology that provides maximum security from hackers, software corruption and hardware failure.

One of the reasons that this latest variant has not hit the US as hard as other countries is related to Federal legislation, such as the HIPPA compliance and financial regulatory laws requiring removal of unsupported computer systems, such as Windows XP and Server 2003, from production.  Since these systems are no longer supported by Microsoft, security flaws do not get patched and hence these systems are most exposed to malware and viruses.

Be a savvy email user. 

When you look at an email, check the sender section.  Most of the time, the senders email address is exposed.  On phishing emails, you will see two addresses, one looks familiar and the next is totally unknown.  This simple test is your first line of defense.  Do not open attachments from emails with suspicious addresses!  Delete them and if you think you were wrong to delete that message, ask the sender to send the information to you again.

Be a savvy website user. 

We all mistype a website.  Once you realize your mistake, leave that site immediately.  Malicious websites often don’t let you break that connection.  So, the quickest solution is to right click in an open spot in the toolbar at the bottom and select the choice task manager.  Locate the browser you are using left click on it to select and then select End Task in the bottom right corner.  If you are still in doubt as to the security of your system, restart your computer and download Malwarebytes from https://www.malwarebytes.com/ and select the free download button.

There are other ways for this malware to infiltrate your network using open ports on your firewall/router.  Griffin Networks is strongly urging all of its clients to stop using Remote Desktop Connections unless they first establish a VPN (Virtual Private Network) connection between their machine and their work network.  Please ask us how to secure your network.

These steps may not entirely protect your network from ransomware, however it will reduce your exposure.
