Linux system backdoor technology (hiding accounts)Every time we get a Linux Server bot, our biggest wish is to keep it forever. Of course, it is impossible to keep it forever, but we should try our best not to let it fly away. This requires the use of the Linux backdoor technology. This is a complex technology, and my skills are limited and cannot be comprehensive. I only hope this series of articles can provide you with some ideas, open the door to y

At the same time, we know that in the object-oriented advanced language, creating an object containing private members is one of the most basic features. It provides attributes and methods to access private members to hide internal details. Although JS is also object-oriented, there is no internal mechanism to directly indicate whether a member is public or private. In other words, relying on the language flexibility of JS, we can create public, private, and privileged members. Information

About process hiding: Remote thread injection: Delphi/Windows SDK/API Http://www.delphi2007.net/DelphiAPI/html/delphi_20061205213557120.html I searched a lot of questions about process hiding on the internet, almost all of which were implemented through remote thread injection. I made one based on Huludao, but it always fails to request memory space in the target process. I don't know why. Please kindly adv

http://renyanwei.iteye.com/blog/258304First look at the rules for overriding and hiding methods and variables in Java when they inherit1. Instance and static variables of the parent class can be hidden by a variable of the same name in the quilt class2. Static method of the parent class the quilt class with the same name static method hidden3. Instance methods of the parent class overridden by an instance variable of the same name in the quilt classTh

There are n methods for controlling the display and hiding of HTML elements:HTML hidden, display of CSS, hide of jquery () and show (), Bootstrap. Hide. Today's focus is not to show and hide, but to listen to a Boolean variable value that automatically changes the display and hiding state of the element. Listening functions, if judgments, choosing the DOM, setting up the DOM,5 lines of code are not possible

This digest is from Dr. Lin Rui's "High quality C++/C Programming Guide".The overloading, overwriting (override) and hiding of member functions are easily confused, and C + + programmers must make sense of the concept, or the error will be hard to find.1. Overloading and overwritingFeatures that are overloaded by member functions:(1) The same range (in the same class);(2) The function has the same name;(3) different parameters;(4) The virtual keyword

1, integrated into the program In fact Trojan is also a server-client program, in order not to allow users to easily delete it, it is often integrated into the program, once the user activates the Trojan, then the Trojan file and an application bundled together, and then uploaded to the server to cover the original file, so even if the trojan was deleted, As long as the application bundled with the Trojan, the Trojan will be installed up. Bound to an application, such as binding to a system fil

subclass is to be derived. Dynamic Member, which is associated with the object. This approach is called portal wide-opening. There is a copy of attributes and methods in the memory of each class object. That is to say, how many objects are instantiated and how many memory copies are there. This is not a good thing in terms of efficiency, but it is highly feasible to use it. Although the memory usage is high, some tips can be used to minimize the memory overhead. For the time being, there may

Function Overloading ConceptsOnly C + + has an overloaded concept, and C does not.Different overloaded functions are distinguished by the difference in the row parameter list.If the global function and the member function have the same name, they are not overloaded because they have different scopes, so the member function will hide (mask) the global function.Overloading of member functions, overriding and hidingOverloads occur in the same scope, and overrides occur in different scopesOverload:T
