The 5 most common hacker techniques you need to know

hacker techniques

Illegal activities to obtain unauthorized information are known as piracy or unethical hacking. This is done by modifying the system characteristics and exploiting its loopholes. In this world where most of the things happen on the net, piracy provides more and more opportunities for the hackers to obtain unauthorized access to unclassified information, such as credit card details, email details and other personal information.

For this reason, it is important to know some of the piracy techniques commonly used to obtain personal information.


A Keylogger is a simple software that registers key sequences and the keyboard’s activity in a register file in the computer. This files can even contain ID’s and the passwords of personal email accounts. While software-based tap registers focus on the programs installed in a computer, hardware devices focus on keyboards, electromagnetic emissions, smartphones sensors, etc.

The Keylogger is one of the main reasons why online banking sites give us the option to use their virtual keyboards. When carrying an operation in a public place, it is best to be extra cautious.

Denial of service (DDoS)

A denial of service attack is a piracy technique that attempts to make a website or server unavailable by overwhelming it with traffic. The server can not process all the requests in real time and finally fails. With this popular technique, the attacker overwhelms the target computer with a huge amount of requests in order to overflow the resources. At the same time, this interrupts responses to the real requests.

For the DDoS attacks, pirates usually use bots and zombie computers. Their only job is to overwhelm the system with requests packages. With every year that passes and the advance of malware and hackings, the size of the DDoS attacks keeps on growing.

Fake WAP

Hackers can use software to fake a wireless access point, even just for fun. This WAP connects to the official WAP of the public place. Once you connect to a fake WAP, a hacker can access your data.

This is one of the easiest attacks, it only needs simple software and a wireless connection. Anyone can name a WAP with a legitimate name such as “Airport of Barajas WiFi” or “Starbucks WiFi” and start spying on people. One of the best ways to protect against these attacks is to use a high quality VPN service.


Phishing is a piracy technique in which a hacker imitates a website and catches victims when they send the fake link. Combined with some social engineer, it’s one of the most used and most lethal attacks.

When the victim logs in or enters some data, the hackers obtain the victim’s private information using a Trojan that is executed on the fake website.

Viruses & Trojans

Viruses or Trojans are malicious software programs. They get installed in the victim’s system and send data to the hacker. They can also block files, show fake ads, redirect traffic or spy on a device’s data.
