What is YARA?
YARA is a tool used in cybersecurity for detecting and identifying malware by applying customizable rules based on patterns or characteristics found in files or processes. Often called the “Swiss Army knife” of malware analysis, Yara allows security professionals to create rules that describe specific attributes of malicious files, such as strings, behavior, or file structure. These rules can then be used to scan systems or files for matches, helping to identify known or suspicious threats. Yara is widely used in malware research, incident response, and threat hunting.
