Well holy smokes. I don't know which repository you contribute to, but if you're getting undermined by such James Bond-esque deception by super villains, in addition to someone spending 6 figures into breaking your stuff, I'd hope you'd at least review the commits you sign with your key after glancing at it.

In addition, you'd have to have everyone else not notice it, all the insanely cheaper exploits not been tried on your current setup, and all the other stars aligning...
