A recent #Amiga demo "Backslide to Arcanum" by Cosmic Orbs included a mind-blowing fullscreen 50Hz rotozoom effect on Amiga 500. Having created a rotozoomer on A500 back in the day I knew exactly how incredibly hard it is to make such routine run fast. The effect has now been dissected and there's also author's writeup.

The backdoor author was working with #xz project for 2 years, and actively fixed "valgrind problems" caused by his backdoor. He also tried to push the backdoor to Fedora 40 and 41.

To quote the post at https://news.ycombinator.com/item?id=39866275 :
"He has been part of the xz project for 2 years, adding all sorts of binary test files, and to be honest with this level of sophistication I would be suspicious of even older versions of xz until proven otherwise."
