Today we will tell you how a computer is infected with a Computer Malware and How can you take care of it.
First let’s talk about how Computer Malware gets on your computer. One way you can get a security risk is through a bundled free software program, free is never usually a 100% free when it comes to software and apps. There’s always some sort of trade off, a lot of the time free software companies will partner with other companies and bundle additional software’s within the download. Mostly these programs are bundled with toolbar add-ons, however hidden within the software packages can be Spyware add libraries and even Browser Hijackers. Well these are not Malware, but they can still pose security risks to your computer.
Another way to get Computer Malware is through file sharing sites, downloading content illegally is bad but it’s highly popular. Using a client like BitTorrent users can download media via peer-to-peer sharing. However, these files tend to travel across multiple computers which probably don’t have internet security software, so they are easily infected with Malware. Additionally, hackers can setup fake files on these networks that are based on popular downloads that are actually Malware in disguise. A newer form of Computer Malware was recently found concealed inside the firmware of a USB stick.
For more software embedded in the hardware device and used for the basic functioning of the device. Since the malware is hidden in the firmware and not the storage area of the USB stick, it’s very hard to detect. Attackers often have help getting on your machine in the form of exploit kits, these are malicious tool kits that attackers use to search for software vulnerabilities on their targets computer.
The kits come with pre-written code that will search for the vulnerabilities and once it’s found the kit can then load malware onto the computer through this security hole. These exploit kits allow attackers to infect us while we web browsing and it’s called a Drive-By Download. This is a download that occurs when a user visits a malicious website that’s hosting an Exploit Kit. There is no interaction needed on the user’s part other than visiting the infected web page, the Exploit Kit will look for the vulnerability in the software of the browser and inject Computer Malware via the security hole.
One of the newer ways to get Computer Malware is through Malvertising and it’s rising in popularity among cyber criminals. The hackers will purchase legitimate advertising space on legitimate websites and within the ad will be malicious code. Similar to a Drive-By Download there’s no interaction needed on the user’s part to download the Computer Malware. Often the attackers will fool you into infecting yourself, this is called Social Engineering. Think of a phishing attack you might get an email, instant message or other social media notice asking you to click on a link, sometimes these appears friendly notices from friends but they can also appear as scare tactics telling you have a problem and you have to respond immediately.
Clicking on that link can trigger a Drive-By Download the one we just talked about. You have to be very careful about what you click. Sadly, even in today’s digital age people still don’t understand the true need for an Internet Security Program. The cybercriminal industry cost the global economy approximately $300 billion a year. These numbers alone are prove how essential is it to have protection across all your devices as businesses certainly booming in the Malware world.
