How safe is Ubuntu?

post #1 of 97
Thread Starter 
Newb Ubuntu user here.

I've been running Ubuntu 10.04 for a few months now and am very happy with it, but my hotmail account recently got hacked (sent out a lot of spam to my contacts and deleted all of my emails ). Now I'm concerned. Is it possible that I have some kind of trojan or malware on here or is it an external hack? The only other time I check email is at school but I figure my school's network should be safe....

Is there anything I can do to check if my machine has been compromised?

Thanks!

Good question. Just started using Ubuntu myself. Eager to see what answers you get.

Ubuntu has a very small percent of the market share. Technically speaking it isn't really much safer than windows, but its so obscure that no smart hacker is going to try to exploit it. Ask yourself, 'if you were a hacker, would you make a trojan for 10,000 PCs, or 30 million? I would guess that somebody just blindly guessed your password or your recovery questions.

It's very unlikely that it had anything to do at all with the Operating System at all; the same thing would have happened if you were using Mac OS or Windows.

The problem is a lot of sites look like they are legitimate or not. I see this a LOT on facebook, click on a link on a wall post and it asks for your facebook username and password. Pay close attention, and you'll notice that it isn't legit.

I have a very hard time believing that Ubuntu is the source of your problem. I am suspecting your school's computer.

First, nothing autoinstalls like it does in windows.
Second, you would have had to give root permissions to install a trojan or something packed with one.

If you are worried, just get Clam, Avast, or AVG and do a scan. I've been running linux 8+ years and never run into any sort of virus or malware, and have never run an antivirus.

OS hacks like that aren't likely, chances are you used a poor password, or gave up your password some how.

Could be someone in your schools network. One of the guys at my school has been playing with our network and showed me that he can get a password from the network with me just logging into an email service.

Speaking off of what i have heard, its actually more likely that it got hacked via an infected pc at your school (or a classmate hacked into it) than getting anything on ubuntu... Especially seeing as most school pc's still run XP.

i've been using linux for about 5 years now, and i've been all over the net with, lots of dodgy sites to boot, never even seen so much as a hint of any sort of malware or virus that runs on linux...

you honestly don't know what you are talking about do you? just thought you come in here and throw some propaganda around? actually since you didn't bother to actually do the research why linux is much more secure than windows and mac osx, i'm not gonna waste my time trying to explain it to you.

Its more likely an exploit in more common software like Flash / Java / etc then an intrinsic Linux specific exploit. Most common are poor password strength and/or adware via browser.
