Jpg virus

A jpg virus isn't too common but they happen. Usually the message is some sort of social media email saying "hey check out my nekked bod" with an image attached. Even a savvy user may be roped in to running this virus. It's just a jpg right? What's the harm?

That's the harm. When you open this, bad stuff happens. In this particular case only 1 of 50 av companies are finding it as malicious (Qihoo-360 shows virus.exp.wrar.2014.0401). It looks to just be a dropper and downloads a zbot after it runs.

I always use examples like this when I hear people say careful browsing and common sense are all you need to stay safe. Image viruses are nasty things to catch if you aren't paranoid and investigate a file before opening.
