One of the other methods cyber criminals use to gain entry to networks is taking advantage of weak passwords, either buy buying them on dark web forums or simply guessing common or default passwords.

To prevent this, organisations should encourage employees to use more complex passwords and accounts should have the additional security of multi-factor authentication, so if an intruder does manage to crack login credentials to gain access to a network, it's harder for them to move around it.

Businesses should also make sure they're prepared for what could happen should they end up falling victim to a ransomware attack. Regularly creating backups of the network and storing them offline means that if the worst happens and ransomware encrypts the network, it's possible to restore it from a relatively recent point – and without giving into the demands of cyber criminals.
