Normally #crashing is not a good thing, but in this case we see #nasa purposefully #crashing into an #asteroid to test their ability to change it's #trajectory https://hackaday.com/2022/09/26/watch-na.. This will provide #valuable #data in figuring out how to prevent #collisions with the #earth in the #future . Quite a cool moment!
Yeah you probably shouldn't be using MD5 #hashes anymore: https://github.com/corkami/collisions It seems now #trivial to #generate #collisions - very cool for #cracking old #technology . We can now make *some* SHA1 #collisions happen, I imagine in the #future we can make #hash #collisions happen trivially for something like #git or for #password checking.
#apple 's #csam is even worse than previous thought, people are finding #hash #collisions in the wild: https://blog.roboflow.com/nerualhash-col..

They should at the very least put #csam on ice until #researchers have been given more time to figure this out. Also, claims that it's "not the final #version " is not good enough, especially when you invited people to #attack it!#apple are claiming there is no issue with their #csam #detection #algorithm because #researchers are not using the "final version", despite being invited to #test it: https://www.vice.com/en/article/wx5yzq/a.. The lack of awareness on this is actually shocking... Even if researchers can't produce #hash #collisions on the #private version, #independent #nations can!
