What action should be taken if a computer is destroying evidence?

The appropriate action to take if a computer is destroying evidence is to shut down the computer by removing the power cord. This method is critical to preserving the data that may be lost if the computer continues to operate or if automated processes are modifying files. Leaving the computer on in hopes of documenting activities could lead to further data alteration or loss, which undermines the integrity of the evidence.

Starting a forensic imaging process immediately without first preserving the current state of the computer could also risk losing volatile data, which may be crucial for the investigation. Contacting IT support before taking any action might introduce delays that could result in the loss of evidence. Therefore, the immediate and decisive action of shutting down the computer is essential to protect any potential evidence contained within it. This approach is widely accepted in forensic investigations to ensure that the original state of the data is maintained for examination.
