Sandboxing and virus scan websites:
https://www.hybrid-analysis.com/ - this is a personal favorite, shows a lot of information
https://malwr.com/ - has been “coming back soon” for a while. I’m just waiting
https://www.virustotal.com - another personal favorite. Once you scan something, go to the “community” tab and you will find links to other sandbox websites like hybrid-analysis and VMRAY.com (can’t search directly into vmray but here’s and example of the analysis they do https://www.vmray.com/analyses/a2cdac363d64/report/overview.html)
https://virusscan.jotti.org/en
https://www.joesandbox.com/
http://cloud.iobit.com/
https://valkyrie.comodo.com/
https://any.run/ - another favorite, here you can directly use the virtual machine just like a regular windows computer. the free version is enough, but premium service has more options.
