UNC2465 used phishing emails and legitimate services to deliver the SMOKEDHAM backdoor. SMOKEDHAM is a .NET backdoor that supports keylogging, taking screenshots, and executing arbitrary .NET commands. During one incident, the threat actor appeared to establish a line of communication with the victim before sending a malicious Google Drive link delivering an archive containing an LNK downloader. More recent UNC2465 emails have used Dropbox links with a ZIP archive containing malicious LNK files that, when executed, would ultimately lead to SMOKEDHAM being downloaded onto the system. UNC2465 has used Advanced IP Scanner, BLOODHOUND, and RDP for internal reconnaissance and lateral movement activities within victim environments. The threat actor has used Mimikatz for credential harvesting to escalate privileges in the victim network. Mandiant has observed the threat actor using PsExec and cron jobs to deploy the DARKSIDE ransomware. UNC2465 has called the customer support lines of victims and told them that data was stolen and instructed them to follow the link in the ransom note
