Preventing Common Mistakes in Computer Crime Investigations

Navigating Pitfalls: A Guide to Preventing Common Mistakes in Computer Crime Investigations

Introduction:

In the realm of computer crime investigations, avoiding common mistakes is crucial to ensuring the integrity and success of the process. This guide explores prevalent errors made by investigating officers (IOs) and provides essential insights to sidestep these pitfalls.

1. Operating the Computer System in Question:

IOs often make the mistake of attempting to operate the computer system under investigation. However, this can backfire as criminals may manipulate their systems to destroy evidence or files. For instance, a seemingly harmless command like DIR can be tampered with to erase the hard drive. Operating the questioned system using its native OS should be strictly avoided. Seeking help from non-experts or local operators unaware of forensic procedures can worsen the situation.

Example Illustrating the Mistake:

An IO, eager to gather evidence, operates the suspect's computer to understand its contents. Unbeknownst to them, the criminal had implanted a destructive program that triggers specific commands. The IO inadvertently activates the program, erasing crucial evidence.

2. Getting Help from the Computer Owner:

Allowing the computer owner to operate the machine is another serious blunder. This risks contaminating evidence or even unintentionally triggering malicious actions embedded in the system.

Example Illustrating the Mistake:

During an investigation, an IO asks the computer's owner to demonstrate certain activities. Unbeknownst to the IO, the owner executes a series of actions that erase files related to the crime, impairing the investigation.

3. Improper Transportation of Computer Evidence:

Failing to take adequate precautions while transporting electronic evidence is a common mistake. Computers are susceptible to physical shocks and electrostatic interference, which can compromise the integrity of the evidence.

Example Illustrating the Mistake:

IOs hastily gather computer equipment without proper cushioning or grounding during transportation. The sensitive components suffer damage due to shocks, rendering potential evidence useless.

Conclusion:

In the intricate realm of computer crime investigations, avoiding these common mistakes is paramount. By refraining from operating the suspect's system, limiting owner involvement, and ensuring proper transportation protocols, IOs can preserve evidence integrity and enhance the chances of a successful investigation. Learning from these mistakes is a significant step toward fortifying the quality and credibility of digital crime investigations.
