Do you know how ransomware works?

If you’re not completely sure what ransomware is, you’re not alone. According to research by Trend Micro, 11% of UK organisations have never heard of ransomware and a further 20% don’t know how malware works.

matrix-434036_1920Ransomware is considered one of the most sophisticated malware programmes and in 2015, almost 40 per cent of organisations based in the UK, US, Canada and Germany were hit by it. Ransomware is a computer virus that threatens to delete your files unless you pay a ransom, which could be anything from £1000 to £150,000, or even more. Considered the fastest growing form of computer virus, it finds its way onto a device by exploiting a security flaw in software or by tricking someone into installing it i.e. email attachments.

If you’re hit by ransomware, there is only one way to ensure you’re not paying out thousands in ransom to get your data back, and that is by having an effective back up in place. Backing up your system is, without doubt, one of the best ways to protect yourself and your company from the harm caused by serious cyber-attacks, data loss and corruptions, however it is reported that 36% of companies are still not backing up their data. If you don’t have an effective back up plan in place, now is the time to talk to your IT provider.

As well as backing up your data, here are 3 things you need to do to minimise the risks of being hit by ransomware:

  • Secure your network – make sure you only allow staff access to what they need and use boundary firewalls to block unwanted traffic.
  • Don’t open unsolicited attachments – if you don’t know the sender or you’re not expecting a file from someone, don’t open it.
  • Educate staff – make sure they know what the threats are, how to minimise the risks, and that they know what to do if they think their computer is infected.
