The Ransomware Social Contract

I had been anticipating this for a while: there has finally been a publicly known case where the social contact between ransomware extortionists and their victims had been broken. The contract? That after paying the ransom, the victims would be given access to their files.

What is ransomware? Extortionist criminals are now using this tactic to make money. They break into their victims computer systems and encrypt their data. The victims are then told to pay a ransom in order to get the key to decrypt the data. Imagine the situation where all your photos and work in your computer are inaccessible, despite still being in your computer. If you could pay a small amount to make this problem go away, odds are that you would.

Now multiply the volume of data a million-fold. A business is hit. Their daily operations requires this data to be accessible. Every second that they do not have it is money lost. If it is a hospital? Hospitals have been hit and left unable to provide effective care to their most vulnerable patients for short periods. Most would be willing to just pay the small amount in ransom than put their work in jeopardy.

Low ransoms and the fact that the extortionists have kept their promise of providing the decryption key have made ransomware a viable business model. This may be finally over. One hospital paid the ransom only to have the extortionists ask for more. The ‘social contact’ is broken. It was always a possibility that the attackers would go back on their word. It has happened.

Ransomware is not a new phenomenon. It has been around almost since three decades ago. For some reason, it just took off as something big in the last three years. Perhaps the existence of commercial software such as exploit kits that package various methods of attack without requiring much technical skill on the part of the attacker helped its rise.

What now? Ransomware is not about to go away. We should practise some IT security 101 to protect the data that is precious to us (yes, really). Backing up data is the old-fashioned and effective method that protects against the loss of data (ransomware or otherwise). Knowing not to click on unknown links or open dubious email attachments helps too. Keeping your operating system and software updated and having an anti-virus enabled is another. These things are all IT security 101 and knowing and practicing them will protect you against more than ransomware.

What if you have been hit and do not have a backup? You could pay, but be aware that you are depending upon the mercy of criminals.
