Guidance on protecting your PC from a Ransomware Cyber Attack

We have all probably heard about this in the news over the past few days.

You might find the following guidance issued by the Action Fraud (National Fraud Intelligence Bureau) useful.

Key Protect advice for individuals:

  • Install system and application updates on all devices as soon as they become available.
  • Install anti-virus software on all devices and keep it updated.
  • Create regular backups of your important files to a device (such as an external hard drive or memory stick) that isn’t left connected to your computer as any malware infection could spread to that too.
  • Only install apps from official app stores, such as Google’s Play Store, or Apple’s App Store as they offer better levels of protection than some 3rd party  stores. Jailbreaking, rooting, or disabling any of the default security features of your device will make it more susceptible to malware infections.

Phishing/smishing

Fraudsters may exploit this high profile incident and use it as part of phishing/smishing campaigns. We urge people to be cautious if they receive any unsolicited communications from the NHS. The protect advice for that is the following:

  • An email address can be spoofed. Don’t open attachments or click on the links within any unsolicited emails you receive, and never respond to emails that ask for your personal or financial details.
  • The sender’s name and number in a text message can be spoofed, so even if the message appears to be from an organisation you know of, you should still exercise caution, particularly if the texts are asking you to click on a link or call a number.

Don’t disclose your personal or financial details during a cold call, and remember that the police and banks will never ring you and ask you to verify your PIN, withdraw your cash, or transfer your money to another “safe” account.
The following link will take you the National Cyber Security Centre which has links to where you can down load patches to protect legacy operating systems (Windows XP).  Please seek advice from someone you trust if you are not sure what to do.
