1. Logger class
Use the static logger method logger. getrootlogger of the logger class to obtain the rootlogger. All other loggers are instantiated and obtained through the static method logger. getlogger. In this method, logger. getlogger takes the name of the logger as the parameter. Some other basic methods of the logger class are listed below:

For example, we just inject code similar to the following:When the victim's browser executes t

4. Amazon Vulnerabilities
This is a security vulnerability that allows company servers to receive almost but not completely correct passwords. Fortunately, this vulnerability only affects old passwords.
This vulnerability allows Amazon servers to accept invalid passwords. For example, adding a password with other characters after the 8-bit password makes the password case insensitive. This vulnerability disappears the advantage of a lon

In the last few days because of the Philippine shooting of Taiwanese fishermen in the "Taiwan-Philippine Hacker War", Taiwan hackers once captured the Philippine government's DNS server, forcing the Philippine hackers openly "begging for mercy." DNS security problem has become the focus of research at home and abroad again. And recently, the online has also burst out "54DNS" hijacking incident.

The Driver method connect uses this URL to establish the actual connection.You can bypass the JDBC management layer to directly call the Driver method. This can be useful in the following special circumstances: when two drives can be connected to the database at the same time, the user needs to explicitly select the specific drive. But in general, it is easier to let the DriverManager class handle the process of opening a connection.The fol

Because slf4j is not bound to any log framework, if you add the slf4j-simple.jar to the class path:
Slf4j-api-1.7.12.jar
Slf4j-simple-1.7.12.jar
After compilation, the following output is displayed on the console:

Typical use Mode
The following simple code demonstrates the typical use mode of slf4j.
Import org. slf4j. Logger; Import org. slf4j

In this way, the attacker gets the user's cookie information.Once the victim's cookie information is obtained, the attacker can easily impersonate the victim and thus have all the permissions on the target server, which is tantamount to stealing the identity of the victim. This allows an attacker to arbitrarily exploit the victim's identity to access resources and services on the server, and even destroy the d
