How Hackers Work and How to Protect Yourself?
Computer threats are generally created by computer predators (hackers) whose aim is to persecute others for their personal gain. Once a perpetrator gets access to victim’s PC, he or she installs a malicious code on the user’s system to collect personal information. Hence, stealing, altering, destroying personal information.
But who is that person and why he does that?
All this is done by hacker, usually a skilled computer programmer who finds computer system vulnerability and exploits them for personal gain.
The method he uses is known as hacking, an illegal way of accessing devices, websites to steal personal information that can be used to commit online crimes.
What is Hacking?
Hacking is like scavenger hunt, where hacker needs to collect clues and solve complex logical puzzle hidden in a maze of data and code to get personal and confidential information of the victim.
But why hackers do this?
There is a motive behind each hack performed by hackers, it can be for:
- Data Theft.
- Financial Gain or,
- To gain unfair advantage over competitors.
But what types of hackers do all this?
Hackers can be broadly categorized into three different classes, based on the method and activity they perform:
● White Hat
Hackers who follow set of rules, perform hack by the book, and have full, contractual permission to compromise a system are while hat hackers.
● Black Hat
Name is enough to explain what category of hackers fall under Black hat. Usually hackers involved in illegal activity who hack a system for personal gain fall under this category.
● Grey Hat
Hackers who lie between White Hat and Black hat are Grey Hat hackers. Generally, those who adopt unaccepted ways to access a system are Grey Hat hackers. They don’t have any malicious intent behind anything they do. It’s just that their methods are unacceptable.
Now, that we know who a hacker is, why he hacks into the system. The next step is to know how he finds his target.
How hackers find a target?
Everyone using a computer connected to the Internet is a target. As all connected devices are prone to be attacked by computer hackers and online predators.
Hackers send phishing, spam emails or instant messages to the users and even design bogus websites to deliver dangerous malware. Also, they always look for machines that are not protected by firewall, as they are the easiest target. This means, any machine without a firewall or anti-virus software is a target and anyone who opens a spam mail or downloads malicious attachment is at risk.
Once a target found what does a hacker do to the machine?
Things a hacker can do:
Besides, installing malware, spyware on the connected machine hacker can do following things too:
- Hijacks usernames and passwords, to access bank accounts and to steal money.
- Ruins credits score.
- Can request new account PINs using the details he has stolen.
- Make purchases.
- Add themselves as an authorized user to use your credit.
- Misuse and use your Social Security number.
- Sell stolen details to interested parties, who will then use them for illicit or illegal purposes
Indeed, online predators pose a serious threat and those who think they are safe they are wrong. A simple mistake like downloading attachment from unknown person, meeting a friend online without caution can make you a victim.
How these hacks are performed?
Usually two types of hacks take place around us, zero-day exploits and malicious scripts.
Exploits never seen before, are called zero-day hacks and are the worst and most damaging of all hacks. As no one has ever seen these hacks they cannot detect them and therefore are unable to defend an organization or individual. People behind these hacks are scary smart hackers.
Hacks performed by using a malicious code written by someone to steal data. These hacks are common these days and usually everyone use these scripts to earn money. Running the scripts is not difficult creating one is. The hackers simply need to find target and run the script. With the increasing number of connected devices finding a target has become really simple.
How these script work?
- Hacker sends phishing email to thousands of users with malicious code as an attachment.
- Once the attachment is opened, the malicious code gets installed and hacker can then access all personal information of the victim.
To avoid such hacks from happening one should always run an updated anti-virus on the machine.
