Threat actors are exploiting vulnerabilities in SimpleHelp RMM software to gain initial access, establish persistent remote access, and potentially deploy ransomware. The vulnerabilities allow attackers to create administrator accounts, drop backdoors, and execute various discovery commands. Field Effect has observed the attack TTPs that are similar to Akira Ransomware group, but does not assess with high confidence because they could be adopted by other threat actors
