CryptoWall has returned on steroids.
Apple Users are no longer immune from this Ransomware.
The new version runs on AMD and Intel 32 and 64 Bit platforms including MAC OS X.
There is no fix other than a secure and verified backup.
The ramp up of Ransomware has been reports on CBS This Morning News recently.
Computrs Inc has found limited success with enabling “Shadow Copy” and total success when offsite backups and other types of computer backups have been done. Shadow Copy has to be enabled prior to the infection to allow the data to be recovered if a backup is not available.
Antivirus programs and various Malware or Spyware utilities have not been found to be useful in eradicating this type of infection.
System restore to a prior date does not remove the infection.
CryptoWall encrypts the data making all of the files on the computer unusable.
If a computer becomes infected the recommendation is to immediately turn it off and have the hard drive pulled out of the computer. This will hopefully prevent the infection from completing the process of encrypting the files. We recommend pulling the power cord on the computer and not allowing the computer to do a normal shut down.
