The number of hacker attacks has gradually increased, and the sense of crisis has also risen sharply. If not being careful, you may become the next target of hackers. As the saying goes, "To know how to defend, you must know how to attack." Therefore, if you want to know the most effective way to defend against hackers, you must think in their place. 

Eager to Make Money

In the past, computer viruses attacked key parts of the system components and the computer malfunctioning. For example, change or destroy the basic input and output system (BIOS) of the computer can lead to failure to boot, file damage, and even hardware damage. In fact, for hackers, the destruction of computer data does not have any value in itself. But if the attack is to encrypt the victim's computer data and threaten to pay to unlock it, this becomes a "business", so more ransomware has appeared in recent years (such as WannaCry Ransomware in 2017). 

The Fun of Stealing Private Information

As the number of times we store private information on our computers has increased, the number of spyware and Trojan horses hidden in the system has also increased rapidly. The current malware secretly monitors the victim's computer usage or keystroke logging (Keystroke Logging), such as visited websites, executed programs, and so on. There is no significant impact, but because the user did not actively agree, privacy concerns arise. In other words, the personal data of each user is becoming more and more "valuable" in the current society. 

Misappropriating Computer Performance Benefits

In contemporary computer technology, the malicious software that secretly executes programs behind the scenes is not just spies or Trojan horses. With the trend of cryptocurrency, new types of "mining software" have also become popular. In theory, most mining software itself does not have a security risk. The calculation process will consume computer performance, reduce the running speed of the host, and generate unnecessary burdens. In principle, it will not harm the computer data. But this causes the user's electricity bills to rise, and reduce the service life of the hardware. 

Say “no” to Hackers

If you do not want to be the next victim, you must cultivate a good sense of safety. Such as, we can open a firewall to filter some network traffic from unknown sources, use some secure Internet protocols to encrypt data transmission channels or install anti-virus software to prevent malicious programs and software. This can protect the data on the computer, and also reduce the chance of encounter hacker attacks.
