I would like to have your opinion on the following.
I would like to know how I can open a suspicious file attached to an email without taking (too much) risks. I’ve heard about a few possibilities:
open the file in a Virtual Machine (with internet access disabled?);
open the file from an OS in live mode. Would Qubes OS be much more recommendable than EndOS for this, or could EndOS be considered as ‘relatively’ safe?
Do you know other ways to do that? I’ve heard about containers too, but I’m not sure if they would be useful here (I don’t really understand the way a container works).
Are the above possibilities relatively safe? I think that by relatively safe I mean that there would not be any consequence if the file is a kind of generic malware.
