What do you know about Java? If the answer is not much, then you are not alone. In this article I am going to explore exactly what Java is, and why it is so important that you keep it up to date.

Java or JavaScript?

Java and JavaScript are completely different things, however many people confuse them as one and the same.

JavaScript
JavaScript is a scripting language (like PHP and HTML) that is used in browsers to help render websites, and is also now used to create [relatively simple] desktop games.

We use JavaScript on our blog. One example can be found in our comment form; if you don’t tick the box to confirm you have read the comment policy and click Post Comment, a box comes up reminding you that you have to tick it to proceed – that works via JavaScript.

You can disable JavaScript, but so many websites use it nowadays, your browsing experience would be significantly affected.

Java
Java is a programming language, which is capable of doing far more than JavaScript. Java can be used to create new programs and applications that run virtually on their own, or via a browser.

Most computers come pre-loaded with Java, as do many other devices, including some cars, printers, parking machines, ATMs and more. A printer doesn’t use JavaScript, as it is a browser based language.

Malicious Java

It is possible for someone to gain access to your computer via Java. All you would need to do is visit a website with malicious Java code on it, and unknowingly to you, you could be being hacked. Some websites allow you to add your own code to their site, (like forum’s for example) so it might not even be a malicious website you are visiting, just one page which contains malicious code.

On face value, a page with malicious Java could look completely normal and trustworthy, as you wouldn’t be able to see the code – your browser would render it for you.

Malicious code can give a hacker almost complete access to your machine, via the internet. They could potentially browse through your files and open applications, and even receive feedback from input devices like a webcam and microphone.

Java Update

When Sun Microsystems (who are now owned by Oracle) developed Java, they didn’t plan for it to be used maliciously, and still don’t. Like with most code, hackers exploit loopholes and flaws in the language, to enable them to perform malicious activity.

Many of the know ways Java can be used to gain access to your computer are preventable, if you have the latest version installed.

It is important that you not only keep your computers version of Java up to date, but also your browser’s version. Many browsers come with a Java plugin, and this can become outdated, even if your system version of Java is up to date.

You should check to see if your browser’s extensions and plugins are up to date ideally once every week. If you have Premier IT Support, or your computer is updated by an external provider, you shouldn’t need to update Java, as that should be taken of care for you.

What are the risks of getting infected by malicious software?

Have you ever thought of what is going to happen when you are infected by a computer malware? About a decade ago, computer virus aims were to replicate themselves and destroying key operating system functions. If you got a computer malware infection at that time, most probably your operating system will be corrupted by the malware and you will need to format your hard disk to solve your problem.

Today, malicious software behaves a little different. We have more than 10 types of computer security threats such as virus, trojan, worms, spyware and many more. Each type of malware has their own speciality and here are top 3 risks of getting infected by a computer malware.

1. Having your login credentials stolen

It is very popular today that a keylogger/keystroke logging is used to log a victim’s login credentials. Once the keylogger has a set of your username and password, they can login into the account and do almost everything unless your account is protected by a two factor authentication.

2. Losing hard disk space

Hard disk space today can be very cheap but we should not waste it on storing malicious software. Malware such as worms will replicate in your operating system and take up your hard disk space. You will not feel the burden at the beginning but as the process gets longer, you will start to feel the pain of having insufficient disk space.

3. Spending money on unnecessary stuff

There is also a type of malware where they scare you off by telling you that your computer has hundreds of infections which you actually don’t have. Upon scaring you, they urge you to purchase a bogus antivirus which claims that can clean all the mentioned infections. All in all, you end up actually paying for nothing.

4. Being part of a minion for DDoS attack

Have you ever thought of how DDoS can bring thousands to millions of traffic to a server? It is actually all the computers which are infected with some sort of trojan that explains how the attacker can have such massive amount of traffic. By getting a malware infection, you are at risk of becoming part of this big project which you do not want to be.

5. Losing your privacy

Another form of malware which is known as spyware is built to spy your daily activities. By knowing your daily activities, the attacker will be able to understand you better before attacking you. For instance, if you regularly surf to adult sites, the attacker will probably start off with some fake adult material to lure you into their trap.

Looking at someones internet usageBack to you now, are you able to take all the risks mentioned? If you are not, be sure you have a good habit when it comes to internet and computer security and always remember that having an antivirus and firewall is not sufficient for a good security.
