Virus Alert – CryptoWall

Urgent Virus Alert

Please take the time to read this entire post to protect your data and your business. Also pass on the information to your staff, so they are aware of the current events.

Some of you might remember seeing a similar warning about 1.5 years ago about a virus called “Crypto Locker”.

In the last couple of weeks a new wave of that virus has hit clients in the Coffs Harbour area.  This one is called “CryptoWall” and it has already impacted businesses in our area! This time the virus comes often in an email like this one:

Once you open the attachment to look at the resume the virus will be activated.

It is a another bad wave of this type of virus, and again virus protection companies are scrambling to catch up with this one, as it changes frequently to elude the virus scanners. In other words: it can affect you if you are not careful even though your virus protection is active and up-to-date.

About the virus:

Calling itself ‘CryptoWall ‘ it displays a warning to users on a bright red screen that their files have been encrypted, while presenting a countdown demanding money to “save” all of their files.

Yes, the virus has the ability to encrypt your files so that you cannot access them anymore.

It’s an especially dangerous situation in a business network, where the majority of the work is being completed and transferred on computers. What is even more treacherous about CryptoWall is its ability to hide itself on your computer, while encrypting your files and make them unusable.

How to protect your data:

  •  NEVER open an attachment from an unknown source, which is vague, or is delivered via an “outside” third party with no personal name attached to it.  If this occurs in your email, delete it immediately.
  • NEVER click on a link in an email from an unknown source, which is vague, or is delivered via an “outside” third party with no personal name attached to it.  If this occurs in your email, delete it immediately.

 

What if one of our computers gets infected?

  • Unplug your network connection immediately (your blue network cable if your computer is a part of a network).
  • Contact Advanced Technology or your computer department immediately.
  • No matter how intimidating the warnings – do not pay for the “key” as the criminals are already at large and will not decrypt your data anymore.
  • Get your IT help desk to clean out the virus and restore your data from the latest backup.

In closing: Don’t panic but you need to be vigilant with files sent to you by other people.
