Unauthorised access continues to be the leading cause of breaches in 2021

Unauthorised access, including sharing or reusing passwords, is still the leading cause of breaches, according to a recent National Management Centre report.

Indeed, this vulnerability is what cyber criminals exploited in the recent ransomware strike on the Colonial Pipeline Company in the US. Attackers were able to use an old, unchanged password in order to remotely access their network.

And the recent RockYou2021 data breach highlights that compromised passwords are becoming increasingly available across the web.

Poor security practice makes it an ideal playground for cyber criminals.

So, what can you do?

One of the simplest things a company can do is to create strong, unique, and regularly updated passwords. See our previous blog entitled World Password Day - Top tips on how to protect your password from cyber criminals. This NMC report outlines how important even simple cyber security can be as a pre-emptive measure.
