In the last few years, it is hard to talk about computer security without the word “Cryptowall” being brought up. In February, Hollywood Presbyterian Medical Center was hit by this strain of infection and forced to pay the ransom to get critical client data back from the attackers.
Many do not understand the nature of the infection, looking only to the result, which is heavily encrypted files. When you trace back the infection, the details you learn are almost as important as knowing that you have been hit by the infection. It reminds me of the saying “An ounce of prevention is worth a pound of cure.” For IT managers, learning how
to prevent these infractions will save you much time and provide a huge reduction in stress levels.
