      Don't worry about it. I know that's not really helpful advice, but I've had experiences like this too. I think of it as "the wheels falling off". I suspect everyone has these times, but most people won't admit it. An uplifting aphorism I heard in a movie: "It will all be alright in the end. […]

      RT @nev i'm well aware canada's healthcare system is vastly inadequate, but just imagine if the housing system were anywhere near what the healthcare system was like. for-profit housing should be as obscene as for-profit healthcare. flipping houses should be seen as as unethical as hiking up insulin prices.

What to do about compromised Hotmail passwords

Posted by Bob Jonkman on 18th November 2010

I administer a number of e-mail systems, and I’ve been seeing a lot of spam coming from Hotmail accounts recently. And both friends and clients have been telling me that it’s not them who are sending spam from Hotmail (and ending up in my e-mail systems), their accounts have been hacked. One person asked me:

Is it just Hotmail? What else could I use? Can’t I just change my password?

Changing passwords is only an effective solution if the account was compromised by social engineering, eg. the legitimate user giving out the password in a phishing attempt or other direct means, or if a simple password was guessed or cracked.

There is evidence that Hotmail and Yahoo’s password recovery mechanism is flawed (eg. the Sarah Palin breach), so that malusers can acquire a new password for an account. I don’t think this is happening, because victims are not reporting being locked out of their accounts. Of course, if the service merely sends out the current password then this may be what is happening, and no amount of password complexity will protect the account.

If the passwords were compromised by an automated password cracker then I would expect only simple passwords to be breached, and accounts with strong passwords would be safe. I do not know what kind of passwords were in use by the people who have compromised accounts, but it is likely they were simple passwords.

While I have no evidence, I think the current rash of breaches is due to a more systematic attack by URL munging, or fuzzing the inputs on a POST request, or some other attack vector. These attacks do not require an authenticated login, and in that case no amount of password complexity will provide security either.

I haven’t heard of similar compromised accounts in Gmail, so that may be a suitable alternative for now. I’ve been recommending that people use the mail accounts provided by their ISPs, largely so that they can make use of the ISP’s technical support if their accounts do get compromised. And, of course, if they’re paying their ISP for a mail account then there may be immunity from liability (“My mail account was compromised and I was paying my ISP for security, so all this spam is their fault”).

–Bob.

Update 5 Feb 2012: I retract the first sentence in the last paragraph. E-mail Administrator friends have been telling me that Google Mail is just as vulnerable as Hotmail and Yahoo. Having just read “Hacked!” in The Atlantic I’m convinced the problem of compromised mail accounts is worse than I thought, and that no online providers (especially the “free” ones) adequately protect the e-mail of their users.
