Engineering feedback from the field is that the number of innocent businesses being affected by increasingly nasty malware attacks are on the upsurge.
While there are many malware programs to be concerned about one that has reached a new sophistication is the CryptoLocker virus. This virus encrypts the victims files, and then refuses to provide the unlock key unless a payment is made – ransomware is back in the spot light.
That’s right you are held to ransom within your own business.
Your Personal Files are Encrypted!
Many current up to date anti-virus programs from reputable companies are not detecting this attack automatically!
The CryptoLocker appears to be spreading through fake emails designed to mimic the look of legitimate businesses. When a staff member clicks on the fake file -boom the virus goes to work.
The virus has the ability to find and encrypt files located with shared network drives, USB drives, external hard drive, network file shares and even some cloud storage drives. If one computer on the network becomes infected, mapped drives could also be affected.
This could be your business files, photos, videos, spreadsheets etc.
Imagine going to work one day and you cannot use any (of your own) files on the system till you pay someone else a ransom. While victims are told they have 3 days to pay the attacker through a third party method there is a growing number of victims who claim they have paid however no decryption key has been provided.
Always keep speaking with your staff and training them on what files they should be clicking on. If in doubt quarantine the file and then have your IT people check it out before opening.
However what if your business does become effected?
From our prospective there are two possible options. Pay the ransom, cross your fingers and hope you get a decryption key that safely unlocks your files and does not perform any further damage. Or delete the encryption files and use a tool to clean the system of any remaining code from the attack and then restore the files from your latest back up.
So YES always have a backup system in place, its that important. The net impact could be a disruption to the business for a few hours including the loss of any file modifications since the backup last ran. This is still much better than the first option.
