Wikileaks reveals a bunch of emoticons used by the CIA to hack
It's called "Faces of the Internet".
More than 8,700 documents were revealed last Thursday by Wikileaks including those "Faces of the Internet": a guide for emoticons.
It's a set of special emoticons probably used in secret communications either by the Agency or by other agencies. The list has been compiled by a certain user #71475. Everything seems to be always coded over there.
Here is an example of what it looks like:
̿ ̿̿'̿'\̵͇̿̿\=(•̪●)=/̵͇̿̿/'̿̿ ̿ ̿ ̿
щ（ﾟДﾟщ） < "Dear god why‽ )
y=ｰ( ﾟдﾟ)･∵. shot my head
You can see it's a well-defined language wich can pass by anyone and you won't even notice something serious could be going on.
On a serious note, this can be a coded language too (you can try cracking it). Though this seems to have a clear meaning, no one can actually tell how it's used or when. ¯＼(º_o)/¯
But according to Jordan Pearson, this could be a complete waste of time by CIA spies.
This list is full of many emotional emoticons, and lovely animals face what gives the impression of a fan and casual tools used by CIA employees. But the comment another user gave under it let's understand that it was a huge pain to get it done: "Oh thank you, you amazing human being". That's the CIA, the mystery continues...
（・∀・） "well" or "good"
（・Ａ・） "bad" or "not good"
