Their modus operandi involves a combination of social engineering tactics and a diversified malware arsenal, including ransomware variants like Black Basta and credential stealers like Cobalt Strike. This multifaceted approach enables them to gain unauthorized access to victim systems, steal sensitive data, and ultimately extort victims through ransomware demands. It has been actively using Pikabot, a loader malware with similarities to Qakbot, in spam campaigns throughout 2023.",

Once UTA0178 had access into the network via the ICS VPN appliance, their general approach was to pivot from system to system using compromised credentials. They would then further compromise credentials of users on any new system that was breached, and use these credentials to log into additional systems via RDP. Volexity observed the attacker obtaining credentials in a variety of ways.",
