: Examining the file’s structure, metadata, and strings without actually running it. This is often the "first line of defense" to identify known signatures. : Running the file in a controlled "sandbox"
The file is frequently associated with malicious activity, often serving as a carrier for Trojans or other forms of malware. These types of files are typically distributed via phishing or untrusted downloads to gain unauthorized access to computer systems. Key Concepts for Analyzing Such Files : Examining
