Ask Slashdot: Is GNU/Linux Malware a Real Threat?

New submitter m.alessandrini writes "I've been using Debian for a long time, and I'm not a novice at all; I install system updates almost daily, I avoid risky behaviors on Internet, and like all Linux users I always felt safe. Yesterday my webcam suddenly turned on, and turned off after several minutes. I'm pretty sure it was nothing serious, but I started thinking about malware. At work I use noscript and other tools, but at home I have a more relaxed browser to be used by other family members, too. Here I'm not talking about rootkits or privilege escalation (I trust Debian), I think more of normal user compromise. For example, these days much malware come from malicious scripts in sites, even in advertising banners inside trusted sites, and this is more 'cross-platform' than normal viruses. So, what about non-root user malware? How much could this be real? And how can you diagnose it?"

Do you deal with customers?

When I ran Linux on my laptop for work I always ran some form of AV. I really wasn't concerned about my own machine being compromised. The scenario that bothered me was the potential for a client to send me an infected file which could get forwarded to another customer. Do to the nature of our business, at the time, that would've been rather embarrassing.

Also, do not ever copy and paste commands directly in your terminal from an untrusted website, even if you do understand them:
