Phishing Scams, Corona Anti-Virus, Free Ransomware Decryption & More: Cybercrime in the Era of Covid19

These are undoubtedly strange times we are living in, with unprecedented changes taking place in our lives all over the globe in order to fight the pandemic that is Covid19. Suddenly, a sizeable chunk of the workforce is working from home, in many cases for the first time. Companies are scrambling to put in place plans to accommodate this, working out whether to allow users to use their own devices, or provide company laptops or desktops for any displaced staff. Moreover, many people are out of work altogether and confined to their homes, spending significantly more time than usual browsing the internet, looking for the next clue online that will bring some certainty to their lives around the crisis they are living through.

With such a shift in online activity comes great challenges for technology companies and IT teams in ensuring their users are safe and their precious company data is secure – meanwhile cyber criminals have seen crisis as opportunity; the misfortune of others is a chance for them to take advantage of the confusion and make some extra money.

Ransomware has crippled various hospitals in the past, including many NHS Trust hospitals which were caught out by the infamous 2017 WannaCry attack.
