How one weak password destroyed KNP

Businesses fail all the time, for all sorts of reasons. So, when a business like Knights of Old (trading as KNP Logistics Group) survives a century and a half, through enough recessions, wars, government changes, and technological advances to fill many history books, it would be fair to say it’s pretty resilient. Sadly, it would be something a lot more minor and simpler that would signal the end of KNP – a weak password.

In June 2025, the 158-year-old British transport firm, collapsed under the weight of a devastating ransomware attack that began with one guessed password. The breach not only encrypted every corner of the company’s digital estate but also obliterated its backups and disaster recovery systems, forcing KNP to enter administration and leaving some 700 employees without jobs.

In an analysis published this week, Specops Software experts dove into what exactly happened with the KNP attack, how the threat actor behind it, Akria, operates, how this all could have been avoided, and the wider ransomware landscape at hand.
