Advisory: Ongoing threat to organisations from ransomware

Created:  20 Nov 2018
Updated:  20 Nov 2018
This advisory gives information on the recent change to more targeted forms of ransomware and suggests simple steps to help prevent a ransomware incident.

Ransomware has been a growing cyber security threat, and one which could affect any organisation that does not have appropriate defences. 

The NCSC has seen a trend to more targeted ransomware attacks where victim networks are analysed to understand their ‘value’ and ransom demands set based on that perceived value.  Criminal actors also seek to ensure that their malicious activity has the maximum impact on the victim organisation – potentially denying the victim access to business-critical files and systems and disrupting the operations of the victim organisation.
