Threat actors employ various methods to deliver ransomware, such as malicious attachments or links in emails; pirated software websites, Peer-to-Peer (P2P) networks, free file hosting sites, and third-party downloaders. They also use fake software updates and Trojans to infect computers with malware.

Ransomware is increasingly being deployed by attackers who have gained access remotely via exposed services such as Remote Desktop Protocol (RDP), or unpatched remote access devices.

To prevent the risks of attack, organisations should:

• disable RDP (if it’s not needed)
• enable multi-factor authentication (MFA)
• use a VPN that meets NCSC recommendations
• use least privilege model for providing remote access
• patch all known vulnerabilities.

The NCSC has an in-depth guide on their website entitled ‘Mitigating malware and ransomware attacks‘, and the EMCRC have numerous blogson the topic of ransomware, including a basic guide to ransomware: Ransomware: What you NEED to know.
