All language subtitles for 7. Spyware, Adware, Scareware, PUPs & Browser hijacking

Continued with types of malware you also have spyware as the name suggests its main purpose is to gather

information and send it back to the attacker.

Well to spy the attackers don't generally want to cause damage directly but want to compromise your

privacy and anonymity based on some agenda that they've got spyware is intelligence gathering malware

corporations and hacker groups create these as well as governments.

You can see the article here of alleged U.S. government spyware from the Telegraph worth mentioning

actually.

Don't get too hung upon the names and classifications of the malware.

By the way that we've gone through these are not strict taxonomies for example a rootkit can also be

a Trojan Horse someone could call spyware virus.

The point is just to understand the variants that exist and the possible purpose of the malware and

other one is and where which some people consider to be a form of spyware is undesirable software.

The forces advertise on you.

There are millions of different variants of this.

One of the most annoying and destructive form of adware is called Kou web search.

You may even encounter it yourself but there's nothing cool about it at all it hijacks your default

search engine it displays ads in the browser.

When you click on links it sometimes takes you to places that it want you to go to instead of where

you want to actually go to and it actively defends itself from being removed and getting rid of it.

So it's particularly hard to shift.

And there are many many variants of it that were affected millions of people when an ad where all malware

takes over your browser in this way is known as browser hijacking.

And you might hear that term more throughout the course you should always pay particular attention when

installing software because often a software install includes optional installs such as this browser

highjacker that we've just mentioned.

So you can see here.

Optional installs and what you've got here is installs that are going to be potential Ad-Aware.

So be very careful what you agree to install.

Always opt for the custom installation and de-select.

Anything that is not familiar especially optional software that you never wanted to download and install

in the first place.

It goes without saying that you should not install software that you don't trust.

Sometimes your device might come with and where pre-installed.

If you're particularly on Lucky One of the worst cases was Lenovo pre-install ING's superficies adware

that only served you add that based on what it knew about you from spying on you.

It also included a self-signed certificate allowing your browser TLR and SSL encryption to be bypassed.

So not very good over and over by our Never bile and over laptop again after that and all the rest of

the things that were never done scare away.

Skyway is a type of social engineering attack to trick a person into believing in a threat that isn't

really real.

So a common example is fake security software claiming that you have malware infections or something

like that.

Often they want you to pay something in order to fix the fake problem.

These scams have been extremely successful.

You can see here personal anti-virus software identifying all these fake their abilities and then is

going to keep popping up.

It's going to keep causing problems on the machine and then people are fooled into paying for something

to remove the fake viruses.

And finally we have this catch all term.

If it's something that you might not have wanted.

These are called potentially wanted programs or pull ups that could potentially be monitored because

the antivirus companies and people the attempt to remove these things aren't quite sure whether you

want them or not.

Most often you don't want them and they're annoying the things bundled them with software.

So again they are often bundling with the software when you install.

So you must make sure when you install software you go to the custom install and make sure you remove

any of these pops.
