Although hacking began as simple entertainment for a group of enthusiastic young people, much has changed since then. Today, all countries have, to a greater or lesser extent, a response or attack group of this type.

It is extremely common for advanced malware not only to hide its code with different packers, but also to try to detect if it is being analyzed dynamically through a sandbox. If they realize that they are watching it, they will modify their behavior to hide their malicious functionality and show completely innocuous functions. In this way, the analysis system will classify the sample as benign and can infect the target system without any problems.
