Behind C and C—even malware has its own backend

Many malware families use some sort of C&C server to receive updates or custom commands from the malicious actor, or to exfiltrate stolen data. Getting access to these backend files can give researchers and law enforcement agencies a lot of information about how malware works and who the victims are. Sometimes, it can even lead to the actual people behind the attack! Therefore, properly and promptly analyzing the code obtained from the C&C is an important task that researchers will face from time to time, so it's better to be ready!
