Are Random Shell Scripts A Threat?

(Column) - After reading this post from the Ubuntu forums, I have to admit that running random code can be dangerous, even on a secure OS like your favorite Linux distribution. But does this mean that using shell scripts should totally be forgotten about? I tend to think not.I Use And Create Simple Shell Scripts. Frankly, I use shell scripts as they save me time and keystrokes. Yet at the same time, I do realize that if misused, it could become a very rough form of malware in the hands of those who wish to cause harm to others. This should prove to be a reminder that not all scripts are safe. But at the same time, let's not become totally paranoid either.Trusting Trusted Sources. What if we take this argument even further? Using this same logic of not trusting most shell scripts, the same could be said for many of the crazy Python scripts that we see posted on a variety of Linux forums. And let me tell you, some of the best scripts I've ever used have come from a random forum posting. So surely there must be a better means of differentiating between the safe and dangerous scrips?Using Ubuntu to Bust Movie Pirates: Fair Or Not?Not having a solid handle on this can make a strong computing solution like Linux just as vulnerable as Windows.Getting a Handle On the Basics. At this point, I don't see anyone having enough incentive to try and take the good natured beliefs of open source and creating something malicious on a grand scale, but at the same time, it could easily be done. And no one wants that, believe me. Imagine the time where malware gets a new birth from the Linux world. It may sound wild, but if properly thought out, it could happen.Today's Scripts, Tomorrow's Malware? Define malware at its simplest - execution of some sort of vulnerability. And with slick applications out there, using source code and floating from site-to-site, there could easily be a malware explosion in the beginner's community.Bundle is a great new, mysterious application, that posts the yet to come source code and allows the package to be installed on various PCs. Never say never, I believe that it just hasn't happened yet. The best hope to contain a potential problem like this is to question why the source code for some application has not been posted.Click here to get the latest prices on Linux distributions!More Articles: - How Linux Users Should React in a Windows World- OS X: Intel Market Share Keeps Rising- Porting OS X to Cheaper PCs: Possible?- Why OS Pricing Matters- Using Ubuntu to Bust Movie Pirates: Fair Or Not?- Subscribe to OSWeekly.com's RSS Feed
