I used to work in security auditing, and it makes me feel pretty jaded to think of the gigabytes upon gigabytes of random stuff that just gets pulled in from everywhere in IDEs, package managers, build pipelines and container images.
At least back then there was still a chance to read a significant part of the code and find problems before they found you.
Almost no manager will sign-off spending time on building stuff in-house if its available "for free".
This is also in no way a new thing. How much code was written in notepad++ in the '00ies? Did anyone bother to check if the plugins did sth. malicious? We also used some weird closed-src "addon" for the Nullsoft installer to get a product out of the door, dont remember what the problem was exactly....
Like Wordpress plugins previously that'll work for now but we're now on the trajectory of relearning that same lesson, because people are automating discovery and exploitation of these extensions and plugins and whatnot around text editors and MCP and so on.
Though I suspect we'll first see a torrent of exploitation similar to what was done to Wordpress instances, and then a change of behaviour, because as you allude to, the people with influence didn't learn from previous experiences with similar technologies.
Turns out no amount of communication to the team matters when you set Copilot to autopilot and it’s not aware of the compromised packages.
I suspect that’s going to be a trend.
I am telling people to wear helmets when they drive a car, this would save hundreds of thousands of lives every year in the world, but somehow I cannot convince them.
