Inherited a system at current (for a few more weeks) employer (recently written so no excuse) that had used a weak hash for the password, I pointed out to my boss how bad it was and that it shouldn't have happened, he didn't pay a great deal of attention.

So I threw the OpenMP variant of John the Ripper at it (I'd just built a 8C/16T Ryzen machine and was curious) it broke ~80% of the passwords in under an hour and all of them over an afternoon of not been in use.

Went to see the boss and gave him the list of passwords including his (which was one of the weaker ones) - he gave me the time to fix it and some other glaring security issues.

The more things change the more they stay the same.

I know enough about security to know that I really don't know about security.






Reminds me of a security issue we had on our linux servers at a former employer. Short of it is, one could run any command as another non-root user without having sudo access or knowing the user's password. rsh access was inadvertently left wide open on thousands of servers.

A coworker and I stumbled into this one morning when I was helping him figure out how to remotely invoke a linux command from a windows gui. I don't recall why we were using rsh as we'd normally ssh into our servers. As we sat there trying to figure out how to enter the password, we decided to just try and run the command w/o a password. We were shocked when it just worked - we were never prompted for a password. When I reported this to my director, he asked me how bad it was. I was like, watch this: I sent an email as the CEO to him saying "you're fired.". He immediately went to our infrastructure team to get it fixed. Fun times...

I'm not sure anyone ever gets past this point. There's way too much for any person to know and not enough hours in a day or days in a year or years in a lifetime to master everything. Even when it comes to computers in general at some level it just becomes magic to me. I might be able to point to a chip and say "that's the sound chip" or "that's a math co-processor", and even write software for it, but I have no idea what goes on inside and I wouldn't know where to even start trying to build one from scratch.


That’s my feeling as well, I try to follow best practices at the level I work at and hope everyone on the levels below me did the same.

Had I done this to any of my bosses I'd have been fired
