Speaking at the 2020 Disclosure conference, Jones outlined how the trust many developers put in their software stacks and shared code, paired with a disturbing lack of online savvy, can make them easy pickings for hackers.

They keep credentials lying about, they're obviously going to have the source code and some production data sitting on their hardware as well."
