Now we are going to look at another way to discover malicious files, by using a sandbox. A sandbox is basically a place where our file will be executed and analyzed. It will check whether any ports will be opened, if it's going to modify registry entries—basically, if it's going to do any suspicious stuff. It's not an antivirus program. Our Trojan might pass antivirus programs, our Trojan passed all antivirus programs, but the sandbox applications, or the sandbox environments, will run it in a controlled environment, see whether it does anything suspicious, and give us a report. We can Google sandbox online, and an example of it is a website called Hybrid Analysis (https://www.hybrid-analysis.com/).
Using the website is very simple: just go to the URL, select a file, and upload it. We can see the report in the following screenshot...
