There has been a significant increase in ransomware attacks globally in recent times. With the WannaCry attack in May the increase in attention paid to cyber crime has compelled many to upgrade their IT Security Solutions and now with the latest ransomware, Petya spreading across the world this urgency is further compounded.
So, What is Ransomware?
It is a malicious program similar to a virus which is designed to scan our hard drive and encrypt as many files as possible to disable our ability to access them. The encrypted files are then held and you have to pay – the ransom – in order to retrieve the files. Other types of ransomware can appear as an email attachment – often a password protected PDF or Word document. Typically these attachments can appear to be invoices or quotes from legitimate- appearing companies. Infection can also occur on an exploited or hacked websites.
In the meantime – here are our Ransomware Recommendations in helping you best protect your business :
- Check twice before you open any attachment, even if you know the sender.
- Do not open any attachment from an unknown sender.
- If the mail or its attachment looks slightly unusual – Do Not Open It.
- Do not store important files on your local PC – Important files should be saved on your server which should have a current backup plan.
Files stored locally are not backed up – if you have no backup we cannot restore your files. Your Anti-virus may not always protect you from ransomware – however please ensure it is updated and running.
If you have been infected
- Shut down the infected machine immediately.
- Disconnect all the shared network drives on your other machines.
- Run your anti-virus.

PLEASE do not pay the ransom, we are aware of instances where the ransom has been paid but the files haven’t been decrypted.
We would like to stress to you the importance of having a backup system in place for your critical files, as there is no way to recover the infected files without the decryption key.
