Vim GTFOBin Abuse - Linux

Sigma Rules

View Source
Summary
This detection rule identifies the abuse of the Vim text editor on Linux systems as a means of privilege escalation or unauthorized command execution. The primary focus is on the execution of shell commands through Vim or its related commands like rvim and vimdiff. By monitoring the creation of processes that include specific command line arguments or images, the rule aims to highlight instances where an attacker may attempt to circumvent security controls by leveraging these tools. The behavior observed, including the use of ':!', ':lua', or shell executions within Vim, is typically indicative of attempts to escape from restricted environments or to execute commands in a manner that is not typically permitted. This proactive detection framework is essential for identifying potential abuse of commonly trusted tools that can be manipulated for malicious purposes.
