Not want to talk about Mau Mau Where is the all encompassing term that refers to all of the programs
that are written with malicious intent.
So my work can include lots and lots of things we'll go through some of the main ones and then we'll
talk about the ones that need to be of particular concern with them.
So top of the list you have macro viruses.
This is a virus that has been written in a macro language such as the ABs that is usually platform independent.
Many applications allow macro programs to be embedded in the documents.
The programs may be run automatically when that document is open.
So that means for example Word documents and Excel documents will have embedded macros and VBA scripts
which can run these macro viruses.
You have stealth viruses or virus that hides the modifications is made virus tries to trick anti-virus
software by intercepting its request to the operating system and providing false some bogus information.
Polymorphic viruses produces very operational copies of itself a polymorphic virus may have no parts
that remain identical between infections making it very difficult to detect directly using signatures
in anti-virus software.
You have self gobbling viruses which attempt to hide from anti-virus software by modifying its code.
So it does not match predefined antivirus signatures.
You have bots or zombies.
And that's really a collection of hacked devices under a command and control of a hacker.
So if your machine does get compromised it could be part of a bot network or being a zombie.
You have worms.
These viruses simply spread from one machine to another to another to another.
You have root kits rootkit are the worst software based malware that you can get.
They are usually embedded into the kernel of the operating system so it can hide its existence completely
from the operating system and then you have firmware root kits.
These are the worst of all.
So for example within your hard drives firmware chip you could have some sort of malware even formatting
your drive and reinstall the operating system won't shift it.
This is NSA GHQ level malware saying that there has been some talk in some papers about how this is
done so it is likely that there are hacking groups actually doing this.
You have key loggers key loggers do as they sound.
They log your keystrokes.
And this Trojan horses Trojan horses or simply programs that appear to be one thing but are actually
malware So you download say for example a piece of software and it acts as that software.
But at the same time it is also malware in the back you have remote access tools all rats.
These are malicious programs that run on your system and allow intruders to access your system remotely.
So they like remote administration tool.
If you're familiar with things like Team view a team view for the hacker.
So remote access tool and popular ones at the moment are hey Vicks alien spy comrade.
These can be bought and these can also be downloaded.
Even though we've gone through all of those different times it's not really necessary for you to know
every type of malware.
You just need to know of them.
Those are outdraw specific attention to are particularly prevalent the moment and the first of those
is ransomware and this typically takes a form of malware taking control of your PC in some way.
Then behind the scenes covertly encrypt all your personal files with a decryption key.
Only the hacker knows then when it's done you will get a message.
Something like these
these are the most prevalent as of recording your options are to pay the ransom.
They tend to crack the encryption which has had much success so far.
Or lose the files.
Most people pay.
They tend to keep the amount relatively low so that people do tend to pay and you paying via a cryptocurrency
such as Bitcoin which is relatively untraceable ransomware because of its high margin profits and rather
simple chain of people need to be involved like likely surge in the near term for PC users.
Next Great concern is Malva Tyson mal the top is an online advertisement that is infected with a virus
malware online.
There are a number of major and minor advertisement networks exist.
Here is an example of what people pay to place ads.
These ads will appear on thousands of different Web sites.
The owners of the sites often don't even know what the specific ads will be.
Hackers are now placing their own ads that contain scripts to get around security checks these scripts
point to all the scripts which download all the scripts from another location and repeat this process
a few times until finally now is present to the user.
The Web site because of this chain of scripts from different changing locations is hard to know for
the advertising network that the ad is bad.
Many of these ads place through automated processes anyway sites themselves can have their own advertisement
network such as Forbes Which also host and malware recently.
So my retirement is a growing attack vector.
You need to be aware of and then we have drive by attacks which is really a bit of a strange name to
be given for simply visiting a Web site that contains code to exploit your machine.
So don't think they're going to only know Web sites will keep you safe.
The example of malwa Times is one reason why.
And also you need to consider if the Web site itself has been compromised.
So here's an example of the UK fat tongue chef Jamie Oliver's website being hacked.
For the third time infecting his surface for the benefit of the hacker that hacked him.
