Cybercriminals operating ransomware as a service from overseas continue to be responsible for most high-profile cybercrime attacks against the UK
The deployment of ransomware remains the greatest serious and organised cybercrime threat, the largest cybersecurity threat, and also poses a risk to the UK’s national security. Ransomware attacks can have a significant impact on victims due to financial, data, and service losses, which can lead to business closure, inaccessible public services, and compromised customer data. Threat actors are typically based in overseas jurisdictions where limited cooperation makes it challenging for UK law enforcement to disrupt their activities.
BlackSuit Ransomware
- In December 2023, we observed an intrusion that started with the execution of a Cobalt Strike beacon and ended in the deployment of BlackSuit ransomware. The threat actor leveraged various tools, including Sharphound, Rubeus, SystemBC, Get-DataInfo.ps1, Cobalt Strike, and ADFind, along with built-in system tools. Command and control traffic was proxied through CloudFlare to conceal their Cobalt Strike server. Fifteen days after initial access, BlackSuit ransomware was deployed by copying files over SMB to admin shares and executing them through RDP sessions. Three rules were added to our private ruleset related to this case.

Ransomware operators exploit ESXi hypervisor vulnerability for mass encryption | Microsoft Security Blog
Microsoft researchers have uncovered a vulnerability in ESXi hypervisors being exploited by several ransomware operators to obtain full administrative permissions on domain-joined ESXi hypervisors. ESXi is a bare-metal hypervisor that is installed directly onto a physical server and provides direct access and control of underlying resources. ESXi hypervisors host virtual machines that may include critical servers in a network. In a ransomware attack, having full administrative permission on an ESXi hypervisor can mean that the threat actor can encrypt the file system, which may affect the ability of the hosted servers to run and function. It also allows the threat actor to access hosted VMs and possibly to exfiltrate data or move laterally within the network.
