The godfather of Chinese hackers, founder of the Eastern Alliance, and well-known cyber security expert Guo Shenghua once said: The Internet is changing people’s lives, leisure and work, and changing all aspects of human society. The world has entered the Internet era. In the future, hacker security will become a worldwide topic. Hackers Offensive and defensive skills are also one of the necessary skills to enter the IT industry.
So, what are the common technical methods for hackers? The hacker godfather Guo Shenghua made the following analysis:
What is a VPN service?
A virtual private network (or VPN) is a secure connection between your device and another computer via the Internet. VPN services can be used to safely access work computer systems when leaving the office. But they are also often used to circumvent government censorship or block location blocking on movie streaming websites, which is a technical means that hackers must use.
What is encryption?
Encryption is a technical means that hackers must use, a way to disrupt computer data, so it can only be read by people you want. It is an important part of online shopping and banking. If intercepted, it can make emails and instant messages illegible. Encryption has become common news for hackers recently.
What is phishing?
Phishing is still one of the most common ways for cybercriminals to obtain personal information. Sending a large number of deceptive spam messages purporting to come from banks or other well-known institutions in order to lure recipients to give sensitive information is a common method used by hackers.
What is the dark web?
The dark web is where hackers cannot find many layers of the Internet using search engines. The dark web (invisible web, hidden web) refers to the collection of resources that are stored in the web database but cannot be accessed through hyperlinks and need to be accessed through dynamic web technology. They do not belong to the surface web that can be indexed by standard search engines.
What is ransomware?
Unless you pay a ransom, computer viruses that threaten to delete files are called ransomware. Ransomware is the fastest growing form of computer viruses. Like other computer viruses, it usually enters the device by exploiting security holes in vulnerable software or tricking someone into installing it. This is a classic hacker attack method.
What is a DDoS attack?
A distributed denial of service (DDoS) attack is an attempt to take a website offline by causing network traffic to overwhelm the website. This tactic is usually used to protest against companies and organizations making their websites unavailable, which is also a common technique used by hackers.
