Penetration testing is a security assessment method. It is also known as moral hacking. This process is carried out by professional security personnel. They simulate cyber attacks with the aim of finding security vulnerabilities in computer systems. These experts use the same tools and techniques as real attackers. Their job is to identify the weak links in the system's defense. This is like asking someone to pretend to steal from a bank to see if the security system is really effective. The objective of the test is to identify potential vulnerabilities that could be exploited and assess whether security measures are working as expected. This kind of test is officially authorized. It is fundamentally different from illegal hacking.The key lies in whether permission is obtained.
Any unauthorized penetration testing is illegal
In China, any security testing of computer systems must comply with relevant laws. The Cybersecurity Law of the People's Republic of China provides a legal basis for ensuring cybersecurity and safeguarding national security and public interests. The Criminal Law also has clear penalty provisions for the act of illegally intruding into computer information systems. This means that no matter how well-intentioned the tester's intentions are, as long as they have not obtained explicit written authorization from the system owner, their actions may constitute illegal activities.
The Yuan Wei IncidentIt is a profound lesson. This security researcher submitted the vulnerability of Jiayuan.com's website through the "Vulnerability Box" platform. He had thought this was to help fix security issues. But later, he was approved for arrest by the procuratorate on suspicion of illegally obtaining data from computer information systems for obtaining over 500 sets of user identity authentication information. This case has made the entire security industry realize that even well-intentioned, unauthorized testing activities carry significant legal risks.
The Wu Yongfeng incidentThen it reveals more serious consequences. It is reported that the former head of a technology company was sentenced to twelve years in prison and fined 300,000 yuan by the court for related actions. These real cases all illustrate an unbreakable rule: in the field of cyber security, technical capabilities cannot override the law. Any probing or testing of another person's system must be based on legal authorization. Otherwise, what awaits the test subjects might not be honor but legal sanctions.

The Importance of a Penetration Testing Authorization letter
Before starting any security test, it is crucial to obtain a formal "Penetration Testing Authorization Letter" with the customer's seal. This document serves as the core proof for testing the legality. It is a contract with legal effect. The authorization letter clearly defines the scope of the test, such as the specific IP address, domain name or system to be tested. It also stipulates the time, methods and objectives of the test. More importantly, it enables customers to clearly understand the risks that testing may bring, such as increased system load or even temporary outages. The customer will sign for authorization only after fully understanding these risks.
A valid power of attorney must be signed by the legal representative of the client or their officially authorized representative and stamped with the official seal. Third-party authorization conducted through an agent must ensure that the middleman has clear authority to sublicense; otherwise, such authorization will not have legal effect. This document protects the testing party, enabling it to carry out its work within the legal framework and avoiding legal risks similar to those in the Yuan Wei incident. It also protects customers, clarifies the responsibilities and obligations of both parties, and ensures that the testing process is controllable and the results are traceable.
