 'description': 'Adversaries may abuse Unix shell commands and scripts for '
                'execution. Unix shells are the primary command prompt on '
                'Linux, macOS, and ESXi systems, though many variations of the '
                'Unix shell exist (e.g. sh, ash, bash, zsh, etc.) depending on '
                'the specific OS or distribution.(Citation: DieNet '
                'Bash)(Citation: Apple ZShell) Unix shells can control every '
                'aspect of a system, with certain commands requiring elevated '
                'privileges.\n'
                '\n'
                'Unix shells also support scripts that enable sequential '
                'execution of commands as well as other typical programming '
                'operations such as conditionals and loops. Common uses of '
                'shell scripts include long or repetitive tasks, or the need '
                'to run the same set of commands on multiple systems.\n'
                '\n'
                'Adversaries may abuse Unix shells to execute various commands '
                'or payloads. Interactive shells may be accessed through '
                'command and control channels or during lateral movement such '
                'as with [SSH](https://attack.mitre.org/techniques/T1021/004). '
                'Adversaries may also leverage shell scripts to deliver and '
