Following the ransomware cyber attack on Friday 12 May which affected the NHS and is believed to have affected other organisations globally, the City of London Police’s National Fraud Intelligence Bureau has issued an alert urging both individuals and businesses to follow protection advice immediately and in the coming days.
Ransomware is a form of malicious software (Malware) that enables cyber criminals to remotely lock down files on your computer or mobile device. Criminals will use ransomware to extort money from you (a ransom), before they restore access to your files. There are many ways that ransomware can infect your device, whether it be a link to a malicious website in an unsolicited email, or through a security vulnerability in a piece of software you use.
Key Protect messages for businesses and individuals to protect themselves from ransomware:
- 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 that isn’t left connected to your network as any malware infection could spread to that too.
