This allows attackers to target only incriminating evidence without erasing the entire log file. The process preserves the structure and authenticity of the log while removing key evidence of exploitation or system errors.

Using sed -i, attackers delete specific entries from these logs that could reveal the commands they executed. This manipulation ensures that traces of their activity, such as disabling security policies or deleting evidence, are erased from …
