Malware Is software that is intentionally designed to cause damage to a computer, server, client, or network. Malware can take various forms, including viruses, worms, trojans, ransomware, spyware, adware, and more. Essentially, if it's software that seeks to harm or exploit any device or network, it's considered malware. Cybercriminals use malware to steal sensitive information, disrupt operations, or gain unauthorized access to systems.
Malware analysis is the process of examining and understanding malware in order to determine its functionality, purpose, and impact. This analysis helps cybersecurity professionals identify how the malware operates, what vulnerabilities it exploits, and how to defend against it.
There are two main types of malware analysis:
Static Analysis: This involves examining the malware without executing it. Analysts look at the code, file structure, and any embedded resources to understand its behavior. Tools like disassemblers and decompilers are often used in this phase.
Dynamic Analysis: In this approach, the malware is executed in a controlled environment (like a sandbox) to observe its behavior in real-time. Analysts monitor system changes, network traffic, and other activities to gather insights about how the malware operates.
