In 2020, the source code of Cobalt Strike version 4.0 was leaked to the public. This tool was recently acquired by HelpSystems. This commercial pentesting tool was developed by researcher Raphael Mudge in 2012.

This tool has been used by attackers to download or upload a file over a network share. PsExec is a free Microsoft tool that is used by IT administrators to execute a program on another computer. Mimikatz is capable of obtaining plaintext Windows account logins and passwords. The malicious software called “Emotet” has used PowerShell to retrieve the malicious payload and download additional resources like Mimikatz – ranked fourth in the tools used by cyberattackers in 2020 and early 2021 in the Sophos report. Attackers use PowerShell to conduct a number of malicious activities, including executing malicious code, creating new tasks on remote machines, identifying configuration settings, pulling Active Directory information from the target environment, evading defenses, exfiltrating data, and executing other commands. PowerShell is a task-based command-line shell and scripting language designed for system administration in the Windows operating system. The report added that when PowerShell is used in an attack, Cobalt Strike was seen in 58% of cases, and PsExec in 49% of cases Cobalt Strike and PsExec were used together in 27% of attacks and the combination of Cobalt Strike, PowerShell, and PsExec occurs in 12% of all attacks. Threat actors, however, have been using these same pentesting tools to break into victims’ networks.Īccording to Sophos report, correlations emerge among the top 3 tools found in victims’ networks.

PowerShell, Cobalt Strike, and PsExec are legitimate tools used by IT administrators and security professionals for penetration testing, also known as pentesting – an authorized simulated cyberattack against an organization’s computer system to examine exploitable vulnerabilities. In the report “ The Active Adversary Playbook 2021,” Sophos found that PowerShell, followed by Cobalt Strike, and PsExec are the top 3 tools used by cyberattackers in 2020 and early 2021. Three legitimate pentesting tools – PowerShell, Cobalt Strike, and PsExec – topped the list of tools used by cyberattackers in breaking into victims’ networks in 2020 and early 2021, according to Sophos’ report based from frontline threat hunters and incident responders.
