In fact, Great Canon (GC) [55] is such an in-path system. But it 
is known for intercepting a subset of traffic (based on protocol 
type) only. What’s more, GC has been activated only twice in 
history (the last one in 2015 [55]).

AT&T security says otherwise:

The Great Cannon is a distributed denial of service tool (“DDoS”) 
that operates by injecting malicious Javascript into pages served 
from behind the Great Firewall."

"The Great Cannon was the subject of intense research after it was 
used to disrupt access to the website Github.com in 2015. Little 
has been seen of the Great Cannon since 2015. However, we’ve 
recently observed new attacks..."

"On August 31, 2019, the Great Cannon initiated an attack 
against a website (lihkg.com) used by members of the Hong 
Kong democracy movement to plan protests."
