Trojan Virus and Latest threats

In computer sciences, Trojan refers to the virus or malware that injects the computer from behind and hides itself by attaching to a file. The sole purpose of inducing Trojan into a system is to leak private information of the user to a third party through a backdoor. Trojan is used to refer to an enemy that attacks from behind the curtain and inflicts possible damage. Unlike any other computer virus, Trojans do not necessarily attach itself to the file to harm it, it does not even replicate itself. The job of Trojan is simply different from others of its kind.

What are the major purposes of wreaking a Trojan virus?

Once inflicted upon a computer, Trojan virus can have the following intentions:

  • Trojans can be used to delete data in the victim’s computer. Mostly a Trojan is designed to interfere with the privacy but some of them are used to get rid of information that might be of huge value to the user. Once the operation is performed, the user won’t ever get to know about the activity.
  • It is oft times used to block the access of some information. The users can try to get back to their data but they won’t be able to as long as they don’t get rid of the virus from the root.
  • Copying data is not exactly seen as a danger but with Trojan inflicted, data keeps replicating itself to the point that it eats up the entire disk space.

Malicious Uses of a Trojan Virus:

  • Leaking information to the third party: Trojans are attached to different emails that a person receives. The attacker then aims to target a computer system and receives information through networking. The virus keeps running in the background while the computer user is unaware of it. Security loopholes or merely bugs created in the programs make it easy for the attacker to induce Trojan inside the system.
  • For anonymizer proxy: some Trojans take advantage of the security flaw in the browser and use the host computer as a Trojan to sweep into the browser and effectively hide the internet usage. The internet service provider or even the government would not be able to spy on your internet activity. This can be used for ethical purposes as well but most of the time, the technology is being used to promote illegal activities without the government supervision.
  • Covering the Tracks: as the name of the virus itself suggests, the malware can be used to carry out a certain activity then cover the tracks later on. The host computer would not be able to figure out the activities that have been done through the computer. The user of the computer would have no record of the preceding actions.
  • Advertising services: while most of the cyber marketing company think of the software as an ethical one. It is still consider one of the biggest violation to user’s privacy. The Trojan starts keeping tracks of the user’s navigation on the internet and produces advertisement on the website that will surely grab the user’s attention. Trojans have a relationship with the worms as they spread through the internet.

This is why Trojans account for 83 percent of malwares in the world.

So, you have your Windows Desktop installing and running, the wind is blowing nicely in your face, and all is going well, until…

What is this? You have been under attack! Any of your actions lead to appearing dozen of pop-ups and warnings! Each site, previously safe, contains unpleasure advertisment and you even don’t know Who and How did it…

BESIDES, it is easy to choose a good antimalware solution according your needs using our mini-guide.

How to keep your computer protected from the Computerized Trojans?

Malware is a wide range of computer viruses that harm the computer in one way or the other, this is why it is imperative to safeguard your computer from all the possible malware threats. These viruses are made for different malicious intents. Unlike legitimate software, Trojans are inflicted into your computer without your consent.

A Trojan horse hides its identity by masking itself as an important utility to the computer. It pretends to be something useful. A number of software applications are made that report of a possible backdoor Trojan that is put into the computer. These software also let you know of any suspicious unreported activity taking place inside the system of which you are unaware of. This technology is able to detect any security bugs inside the code.

When a worm is introduced inside the computer it attaches itself to the auto run file which enable the system and its specific programs to run without the consent of the user. After which the worm starts to sweep throughout the network. It is necessary to eliminate the Trojan in the initial stages before it spreads infinitely.

  1. The first thing that you need to do is disable the auto run in your computer so that the virus does not get executed on its own.
  2. Then search through all the roots of devices and drives attached including the internal and external ones. You will even need to look through all the flash drives.
  3. Once you know what auto run files are there in the computer copy them in the notepad. You will have to go through the entire programming to see if there are any lines starting from “label” or “shell execute”.
  4. Select that specific auto run file and delete it from the drive.
  5. Repeat the same steps for all the drives and get rid of any viruses that execute on auto run basis.

If you are sure that there is no virus left, then you can take a second check from the antivirus software. It is easy for antiviruses to run the check and go through the drives within a few seconds. Worm usually spreads through internet when you click on an unsafe link. So how do you make sure that the link you are about to view is safe enough?

  • Link shortening is one way to fool the users into following the trail. Link shortening is a market used by malware makers to hide the true destiny of the link so if you are extremely anxious about what website you are going to end up on then it is safe to not click on the shortened links.
  • If you receive an email that asks you confirm your identity and approve of the information provided then it is most likely to be a spam. These emails come in solstice forms making it look like they have been received from the emails. So if you receive an email from a bank or some other reliable source asking for some private information then it is only safe to get it rechecked from the bank itself.
  • Hackers are smart enough to change the URL coding. They change the URL to tiny bits making it look like they are destined to some place safe. Hackers can mask any link through this strategy.

Now that you know how to determine a suspicious link, what can make you sure that the link is safe?

There are a number of tools available to check security of the link before actually clicking on it. For example Norton Safeweb, URLvoid and Scan URL. Always take advantage of the real time scanning options provided by the antimalware software systems. If you have installed an antimalware software, then you need to keep it updated as well. if antivirus software is not up to the mark then it won’t be able to provide defense against the newly made viruses including the new threats that keep on coming with them. Install a strong antimalware but do look for a second opinion by installing another one.

Your computer is always vulnerable to attacks. Install a network firewall system that makes your computer practically invisible to the hackers. Hackers use internet and port scanning tools to make their way into the computer. Even if you have masked your computer from the online threats, hackers might still find a way through any ports that you have left unattended and open.

Different types of computer security threats

There are many types of computer threat software that are harmful and harmless yet annoying. Some viruses are so designed that they can force you to buy a huge amount of money and empty your bank account.

  • Scareware: scareware is a kind of Trojan that does not necessarily harm the computer but disguise themselves in such a way that it looks like a threat to the computer and forces the user to buy expensive malwares for absolutely nothing. These malwares that are purchased might be harmful themselves.
  • Rootkits

  • Keylogger: Keylogger is basically a powerful sub-function of the Trojan. It detents all your keystrokes and deliver the information to the third party. It can even lead people to lose their important credentials and passwords to the third party they are not even aware of. This virus can be inflicted independently or might be mixed with a powerful Trojan.
  • Ransom ware

  • Mouse trapping: mouse trapping is a lot like keylogging. The software monitors the navigational movements you make with the mouse.
  • Backdoor: backdoor is not really a malware but is a form of method where once the backdoor is installed it will start leaking your information without your knowledge. This is basically created in a code wherever a bug is detected.
  • Spyware

  • Exploit: exploit is the kind of malware that is specifically designed to attach only the vulnerable parts of the system. So if your internet security is weak, exploit is most likely to target that part. The way to avoid an exploit is to always patch your software. The Exploit provide an open welcome to the Trojans.
  • Botnet: botnet is something which is installed by a bot master to take control of all the computer bots. It mostly infects the viruses already upon the disks or accelerate an already there Trojan infection.
  • Trojan horse

  • Phishing: phishing is the kind of software that is made to look like it works for the antimalware but in reality harms the computer in ways you would not expect. Phishing tricks you into buying the AV software that you don’t really need. This kind of service make tremendous amount of money from the users afraid of getting their computer infected.
  • Cookies: while cookies mostly has ethical uses, it can still be used by the websites to infect viruses into the computer that harms your computer in different ways. Websites use cookies to save specific information into the systems. What most of the users fail to realize is that these cookies can have hidden Trojans in them. It is recommended to only save cookies from the websites that are reliable.
  • Browser Hijacker: a browser hijacker uses the support of Trojan software to take control of the victim’s web browsing sessions. It can be extremely dangerous especially when someone is trying to make transactions through the internet. Accessing social media sites can lead to a waste range of hackers.

Cyber Threats Expected in 2018

  • Real time management challenges:
  • With increasing management demands and customers increasing at a rapid speed, it is expected to see a rise in computer employment rate. AI is being used by the business at an extensive rate. The more you employ robots the higher risks of cyber security increase. The big risk here is that the demand for rapid transactions and payment systems is being made. Computers are mostly hired for fraud detection so that no fake transaction passes by.

  • Social engineering Attacks:
  • Social engineering and phishing continue to be the most profitable kind of attacks and a rising sophisticated threat is expected to take place because of the profitable individuals working behind the gates. These attacks are engineered prior to sending out a Trojan.

  • Mobile Threats:
  • Ever more online activity now takes place via a cell phone. Cell phone has more private data then a desktop computer. Using internet from cell phones make it a welcome threat for cyber criminals to make their way into your private life. They can monitor each and every activity of yours. From keystrokes to online activity, even the transactions you make via a cell phone. The most successfully made malwares are first tested on cell phones. It is so much easier to spread a worm through networking cell phones.

  • Data Breaches:
  • The common concept of data breaching is hacking into a computer system and viewing information that you were not supposed to. The information get stolen such as credit card numbers, PIN or bank account numbers. For hackers it is a bonus when a Trojan is able to view that information in a single attack. A powerful Trojan that directly affects the vulnerable security of the computer is when data breaching can start.

  • Crypto Currency Targets:
  • With more and more financial industries depending upon virtual currency, these businesses are on a threat of getting hit by serious financial crisis. We already see hackers making headlines by targeting these currencies. There are some solutions capable of detecting a fraud coming near these currency. The companies can get back to the traditional methods of physical payments but even the transactions made are not safe from Trojans.

  • Fraud-as-a-service:
  • There is a network of cyber criminals working underground to provide services to different renowned organizations to achieve unethical means. These underground criminals attack from behind the curtains and get paid for it. The clients specify the kind of threat they want to inflict upon the victim and the cyber criminals start working to create the Trojan.
