You might receive an innocuous looking email – it might even look like it’s from your boss – asking you to click on a link. Watch out! It could be the start of a ransomware attack. Over the last year cybersecurity experts say that the number of ransomware attacks has grown exponentially. During the pandemic lockdowns criminal hackers have been able to exploit the vulnerabilities inherent in the increase in homeworking to infiltrate computer systems, shut them down and then demand a ransom to restore services, or even to stop publishing data they’ve stolen. Along with the increased volume of attacks, the level of ransom demands has grown.
Using new technology and techniques, this has become a lucrative business for international criminal gangs, with individuals, businesses, schools, hospitals and charities all targeted.
