A hoxbomb was a weapon the Snarre't had developed thousands of years in the past. The bomb scrambled the sequence of hox genes and added genes in places where they didn't belong. They were actually quite easy to build and deploy. It wasn't long after contact between the Snarre't and humans that both species learned that hoxbombs could also impact humans.[1]

One Sean Cravath was exposed to a hoxbomb while still in the womb, and was born with substantial defects as a result.[2]
