A team is examining a script that grants higher privileges on certain systems. The script includes a poorly documented library and obfuscated function calls. Which method helps confirm if it has concealed hostile components?
Send the script to a scanning service that depends on recognized signatures
Install the script on a shared system to see if it creates questionable processes
Rely on an automated output approach that spots final runtime anomalies
Conduct a thorough manual review, verifying references, library usage, and suspicious calls
Scrutinizing the script directly, including how each function behaves and how libraries are used, uncovers details automated tools might miss. Checking references line by line reveals questionable calls, errors, or obfuscated elements. Other solutions rely on outputs, environment behavior, or partial scanning, which might not reveal internal logic issues.
