Thats a misleading over simplification. A collision being found implies
something different than "its cracked." A weakness that was theorized
sometime ago has been demonstrated in practice. Finding collisions and
altering files in a useful way to produce a duplicate hash are different
things. There are FAR bigger security concerns than this one right now IMHO.
I recall even seeing posts about people claiming this meant original data
being reconstructed from the checksum! That would be truly amazing since I
could reconstruct a 680MB ISO from just 61d38fad42b4037970338636b5e72e5a. Wow!
