People think it’s hard to stay without a phone, but I don’t! My computer has everything a smartphone has like browsers, notes, calendars, and a lot more.

Challenge solution

So the first question that comes to mind is how did I find out that it was a MAC image?
Simple. the imageinfo plugin did not work.

Now let us get the profile of the memory dump.

$ python vol.py -f ../contact_me mac_get_profile

profile

Okay, so the profile is MacSierra_10_12_6_16G23ax64.

The reason I call this challenge very easy since the name of the challenge hints out the plugin that I must be using to probably get the flag & one such relevant plugin that I found was the mac_contacts plugin.

Let us use that plugin.

$ python vol.py --profile=MacSierra_10_12_6_16G23ax64 -f ../contact_me mac_contacts

mac_contacts

If you are able to see, I have highlighted a certain text which looks like a base64 string.

flag

Voila! We got the flag.

FLAG: securinets{31012e16c3e5dfa7e673612d7d075715}
