Following my last blog we are still seeing a large amount of Malware on old & new customer’s computers. Malware gets its name from the term malicious software, this gets installed onto your computers with single click of your mouse. You’ve all heard of Trojans, Spyware, Adware and Randsomware. We would like to help you understand and give and show some examples.
Typically these customers’ computers do have some free security software which gives some protection, the issue is its only a taster of the software. They don’t cover anywhere near enough of what you really need to stay safe while your surfing or even receiving e-mails.
Malware gets onto your computer/mobile device in many ways, however most of the time you agree to install it or action it to start with.
How many of you read the terms and condition on a program you install? How many of you install Apps onto you mobiles device just accepting all the requested App permission it says it needs.
F-Secure has an App to find out what permission you have given on all you apps, if you are Android go to Google play and search for F-Secure app permission, or just click here.
Getting back to Malware, I like to show you some examples of how and what Malware is, and more to the point what can it do.
Adware: advertising-supported software is the full name. These are advertising pop ups, through these they get you to click which then will give you more adware on your computer and will get you to install other fake software.
Trojans: Trojans horse is its full name, these install by posing themselves as something else. These hide themselves and steal data without the user knowing. Trojans do not spread themselves to other computers, they are injected into your computer from another program. One way you can get a Trojans onto your computer is when you use pirated software, or use key generators to made product codes. You think you’re getting something for nothing when in fact you are just getting yourself a stir of trouble. An example of a Trojan is a Keylogger, this logs the keys you press on your keyboard and sends them to criminals that then have passwords you typed in, credit cards and so much more.
Spyware: This will collect data from your computer much like the keyloggers, they take information of where you surf and send this without the owners consent to serve the information for your next popup, these are again 4 classed such as system monitors, trojans, adware, and tracking cookies
Ransomware: This has evolved and from all the virus and Malware. I have seen them become very destructive, and can be very costly even if you have backup of your data in some cases.
The basic Randsomeware infects your computer stopping you from using / accessing your computer and demanding you pay before you can sign on again. Some start-up as you try log onto you profiles saying you had illegal content on you PC or you been surfing child porn and even in some case adding these photos on your front page. There were easy removed and nondestructive to your system, unfortunately these have again become destructive, they start by stopping programs running even after the virus was removed, having to run software to correct the windows installations. (See example Fig 1,)
We are now seeing randsomware like cryptolocker. This infects your computer without you knowing from you clicking an email link or attachment, once on your computer is starts to encrypted all your personal files approximately 2 days before is shows itself. It then asks you to make a payment in bit coins or you will lose all your files. In some cases you can remove the crypto locker and restore your files from backup. Problem is most of your backup files are now also encrypted too, most people sync in the cloud and do no more, there now also encrypted. To top that you are given a time limited to pay before your files will be unreliable. This then try to also find other computers on the network and tries to inject itself to other computers, Below shows images of what randsomware looks like. (Fig 2.)
Now you know more about what you are trying to protect against, our best advice to anyone is, use an award winning security software to give you the best chance of protecting against these threats.
