Malware Analysis
Definition
Malware analysis is the process of examining malicious software to understand what it does, how it works, how it spreads, and how to detect or stop it.
Examples
- A security analyst investigates a suspicious file from a phishing email to determine whether it installs ransomware or steals passwords.
- An incident response team studies malware found on an employee laptop to see what systems it contacted and what damage it may have caused.

Malware is one of the most common tools used in cyberattacks, but simply knowing that a file is malicious is often not enough. Security teams need to understand what the malware is designed to do, how it behaves on a system, what signs it leaves behind, and how far an infection may have spread. Malware analysis helps answer those questions.
This matters because malware can do many different things. One sample may quietly steal credentials. Another may encrypt files, disable security tools, or create a hidden backdoor for later access. If defenders do not understand the malware, they may remove one file while missing the larger threat. Malware analysis turns a suspicious file or process into useful knowledge for detection, response, and recovery.
