The authors slipped malicious exploit code into otherwise-innocent websites, and this code utilized a vulnerability within Java in order to silently install itself.

A vulnerability is a weakness in innocent software that a something (like malware or a hacker) can go through.įlashback is an example of malware that exploited a vulnerability to take over people’s machines. You can see it, interact with it, and analyze it. The difference between malware and vulnerabilities is like the difference between something and the absence of something. But not vulnerabilities or buggy code, or products whose business practices you don’t necessarily agree with. Malware is the big umbrella term. It covers viruses, worms and Trojans, and even exploit code. So, how do these definitions play out in real life? To be usable by malware (or on a larger scale by hackers), it needs to be put into code form, which is also called exploit code. The strange behavior that can be used to create a hole for hackers or malware to get through generally requires someone to use a particular sequence of actions or text to cause the right (or is that wrong?) conditions. That hole is otherwise known as a vulnerability.
And sometimes that strange behavior can be used to create a hole that malware or hackers could use to get into your machine more easily. Sometimes those mistakes create strange behavior in programs.
Humans are fallible and sometimes forget to cross t’s and dot i’s. You run a file that is supposed to be something fun or important, but it turns out that it’s neither fun nor important, and it’s now doing nasty things to your machine.įunny thing about software: it’s written by humans.

In the malware sense, they’re viruses that are self-contained (they don’t attach themselves like a parasite) and go around searching out other machines to infect.ĭo you remember that story you had to read in high school about the big wooden horse that turned out to be full of guys with spears? This is the computer equivalent. These are not parasitic worms, but the kind that move around on their own. Think of inchworms rather than tapeworms. It’s different from other types of malware because it can either be like a parasite that attaches to good files on your machine, or it can be self-contained and search out other machines to infect. This is a specific type of malware that spreads itself once it’s initially run. Not buggy software, not programs you don’t like, but software which is specifically written with the intent to harm. This is a big catchall phrase that covers all sorts of software with nasty intent. Here’s the basic definition for all the terms we’ll discuss here: Don’t forget to protect your Mac from viruses, malware and everything in between: Download Mac Internet Security X8 and get protected today. I thought I’d clear up the confusion by explaining what malware, trojans, viruses, and worms are and how they’re different from one another. One of the most frequently (and painfully) misused groups is the terms that differentiate malware from other types of vulnerabilities and threats. Many of them can be a bit hard to explain in a simple manner, so they often get used incorrectly. There are a lot of heavily technical terms that get used around computer security.
