Linux, politics, and other interesting things
I was doing some routine sysadmin work for a client when I had to read mail in the system administration mailbox. This mailbox is used for cron job email, communication with ISPs that run servers for the company, and other important things. I noticed that the account was subscribed to some mailing lists related to system administration, the following is from one of the monthly messages from a list server:
Passwords for email@example.com:
List Password // URL
That doesn’t seem terribly exciting, unless you know that the password used for the list server happens to be the same as the one used for POP and IMAP access to the account in question, and that it is available as webmail… Of course I didn’t put the real password in my blog post, I replaced it with something conceptually similar and equally difficult to guess (naturally I’ve changed the password). The fact that the password wasn’t a string of 8 semi-random letters and digits is not a good thing, but not really bad on it’s own. It’s only when the password gets used for 3rd party servers that you have a real problem.
I wonder how many list servers are run by unethical people who use the passwords to gain access to email accounts, and how many hostile parties use such lists of email addresses and passwords when they compromise servers that run mailing lists.
Now there would be an obvious security benefit to not having the list server store the password in clear-text or at least not send it out every month. Of course the down-side to doing that is that it doesn’t give someone like me the opportunity to discover the problem and change the password.
