Why is it the most plausible assumption?  Isn't it far easier to
replace the cryptographic libraries on PCs with one that has a
"wrapper" that copies all payloads before encryption and after
decryption, and transmits the payload to the snooper?  Why go
through the hassle of breaking a cipher when all you have to do
is replace a few files on the target's PC to get what you want?
