@arstechnica Reminder of Ken Thompson’s 1984 Turing lecture, Reflections in Trusting Trust, about a1975 hack: https://www.cs.cmu.edu/~rdriley/487/papers/Thompson_1984_ReflectionsonTrustingTrust.pdf It’s even more relevant now given the greatly-increased layers of software used by programmers. Tidbit: AFAIK, out group was the only one to notice this hack, which occurred a few weeks after I’d read John Brunner’s The Shockwave Rider & laughed prematurely at idea of worms with infinitely-replicating tails.
