In November 2023, we identified a BlackCat ransomware intrusion started by Nitrogen malware hosted on a website impersonating Advanced IP Scanner.
Nitrogen was leveraged to deploy Sliver and Cobalt Strike beacons on the beachhead host and perform further malicious actions. The two post-exploitation frameworks were loaded in memory through Python scripts.
After obtaining initial access and establishing further command and control connections, the threat actor enumerated the compromised network with the use of PowerSploit, SharpHound, and native Windows utilities. Impacket was employed to move laterally, after harvesting domain credentials.
The threat actor deployed an opensource backup tool call Restic on a file server to exfiltrate share data to a remote server.
Eight days after initial access the threat actor modified a privileged user password and deployed BlackCat ransomware across the domain using PsExec to execute a batch script.
Six rules were added to our Private Ruleset related to this intrusion.

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.
