How can I deal/inspect a suspicious file on my mac short of installing and creating a full blown virtual machine instance? On windows when I want to open a suspicious file I use the sandboxing app sandboxie Is there something comparable/safe on mac?
Open up the terminal and try:
If you really want some "verbose" information output, then enter:
zipinfo -v zipFileOfInterest.zip
The "-v" option will output a bit more information :)
man zipinfo to get the rundown of what options/etc is available.
You can also try:
unzip -l zipFileOfInterest.zip
These will allow you to peak inside the .zip without extracting what is inside.
