Request for key-logger check -- followed instructions from old threads

Question

Hi everyone,
This is my first post on this site.  I've become worried about malware installed on my computer (credit card info was stolen last week).  After reading several related posts I am hopeful that I don't actually have a key-logger installed on my computer (since I don't think anyone around me installed malicious software, and it seems unlikely a website could install it without my consent), but I would like to be sure.
I have followed instructions posted by Linc, and generated this output in terminal:

I've found several other threads with different suggestions for rooting out and eliminating key-loggers. Is this step (above) sufficient, or is there more I should do?  I just read stuff on the flashback virus (on this forum) and followed some Terminal prompts.  I don't think I have it, but I do think I'm getting paranoid now.
Thanks

Answer 1

There are many, many possible ways for your credit card number to get stolen. Malware on your Mac, while possible, is the most unlikely. So unlikely that I would not consider it without a good reason.
As to the question of how to detect a keylogger... that's very difficult. You can detect known malware fairly easily, with a good anti-virus program. However, no current Mac malware incorporates a keylogger. Most includes a backdoor of some kind, which could be used by a hacker to install a keylogger remotely, if you were infected. Alternately, someone malicious with physical access to your computer could also install a keylogger.
Here's the issue... when you have someone consciously installing a keylogger on your machine, you can't really ever be sure you've detected it. It could be disguised as something legit. It could even replace a system component. Someone with a lot of experience might be able to locate the keylogger, using various methods. You could try to install something like Little Snitch, to intercept any transmissions that software might make... but if someone's already got a backdoor (or physical access) allowing them to install a keylogger, what's to stop them from disabling Little Snitch?
Bottom line, there's really no reason to believe you have a keylogger on your Mac. However, if you should, at some point in the future, become convinced that you have a keylogger, the only true solution will be to erase the hard drive and reinstall everything from scratch.
