And I did come up with a method of how it could be done. Originally I was defaulting to biochemistry/genetic type approaches (which is my personal bias and also seems to be the bias of the conspiracy theorists who claim we invented it) and I still doubt we have the knowledge to do it that way now.
But there is a pharmacology method, serial passage, that has been around since the 1800s and while unlikely, it is at least theoretically possible. Pharmacologists (not my area of expertise) routinely use this method to artificially change target species of viruses for research purposes and both these viruses arose from mutated animal viruses. So in theory it is possible that some secret Psychopaths R Us Inc group used this method.

Combining responses to both cthia and biochem.
The freezers at the CDC and somewhere in Russia contain a lot of odd viruses, bacteria, fungi and other icks -worms, assorted parasites-, many of them highly lethal. One of the scary mysteries of the world is how many of these nightmares are out there in the wild but mostly do not run amok infecting large numbers of people. One of them could do so at any time. No conspiracy by governments, or just idiots, is necessary. Mama Nature can zap us whenever She pleases. There are dozens and dozens of these potential slatewipers toodling around all over the world... but mainly in tropical regions. The wonder is how seldom they strike.
And what, pray tell, may be lurking in the freezers at USAMIID? which is the former home of our bioweaponeers? God only knows. And the freezers of Bioaparat? In the hands of Putin? There's a jolly thought.
And how many other countries or corporations have little germ collections? Or big germ collections? I bet... A lot. And every one of them is an opportunity for stupid and/or sloppy to happen.
Frankly, it is even scarier how many researchers there are fooling around with this and that just to see what they can do. My faith in their competence and safety protocols is not high, due to the lousy track record on the subject. It will only take once. But... this has to be in the same mental file with comet strikes and supervolcanos erupting in cataclysms; stuff I cannot do a darn thing about so -besides giving my self a good scare now and then with a plague that eats the world novel- I may as well ignore it until such time as it actually happens.
There are different strains of HIV which have different affinities that seem to affect who gets them most easily. This could be a basis for the conspiracies... not that paranoid conspiracy theories need any sort of basis.
