May 2017 Newsletter mid-month update: Ransomware

Ransomware – protecting your clients, your firm and yourself

The news last week showed how quickly a cyber-attack can spread. Coverage highlighted the impact on the NHS, but the ransomware spread far and wide across all kinds of organisations and across the globe.

Because of the nature of the attack, machines could already be infected but not yet showing any signs so please be cautions with emails:

  • Never open an attachment that you were not expecting or if you are uncertain of the contents.
  • Look closely at an emails header if you are uncertain about the contents. Although the name associated with the email may be familiar, an odd email address and domain name may a giveaway. It could look something like this:
    • Stephen Ward <gobbledeygook@evil.com>
  • If you see a document that has the format document.pdf.html  - DO NOT OPEN IT – it is a webpage masquerading as a pdf and will have malicious content.
