Ransomware

Cyber criminals are cashing in and it’s big business.

We all know that Ransomware is a hot topic following the recent attack which caused a massive upset to the NHS. Ransomware and Malware, similar to the common cold comes in many strains or as it’s known families, since the first outbreak in 2012 there have been 249 families discovered.

Cyber criminals which released and caused the spread of the WannaCry ransomware variant across 150 countries have been reported to have been requiring £230 per computer to unlock and decrypt files so data could be used again. They don’t just ask for this ransom to be sent to their bank account, they ask for this fee in digital currency or crypto currency such as BitCoin or Etherium which are legitimate currencies. BitCoin has a hidden talent and can be used anonymously meaning money can be transferred all over the world without the usual banking paper trail.

Since the WannaCry outbreak there has been a new more competent strain released but this time it came from the Petya family, which should have you worried. The Petya crypto-ransomware has extra built-in capabilities that allow it not only infect a machine but then it will look on your computer network to find other computers that it can infect before rebooting your system. When it restarts the computer it will not only encrypt your data files but encrypt part of your Windows system meaning it’s unusable, then it will display a message asking for a ransom.

These devastating pieces of software are usually spread via email containing a link which the user will need to click thus infecting the computer.

There is good news –

These ransomware families can be protected against by using by using reputable security software, you should keep your systems and software patched with the latest security updates, and depending on system type make this automatic. Educate your staff on the dangers of clicking on links in emails and have a good firewall in place that can filter traffic passing through it to detect threats. Maintain a backup of your data, this should be automatic and not need any human interaction, you should also periodically test that backups work.
