Freegate traffic encryption is hard to break and analyze.
And it has many distracting cover traffic.
Therefore, gfw team reverse engineered freegate code years ago,
There are even Chinese papers on freegate reversing.
Freegate is facing extreme hostile environment.
So, the latter version checks user pc for debugging environment
which causes strange behavior than normal proxy software
But this didnt stop the gfw team from further reversing
They cracked f2 f3, which's why they're currently abandoned here
Now freegate adopt polymorphic packer and f4 as latest defense
Most polymorphic packer are well-known false alarm generators.
