My study notes---python grey hat The world makes me black and blue, but the wound is wings.--------------------------------------------ObjectiveThis book is written by Mr. Lead author, senior Black Hat Justinseitz, a well-known security Agency IMMUNITYINC, about how programming language Python is widely used in the field of hacking and reverse engineering.Fortunately, I will be interested in this area, junior high School has involved a drop point reverse engineering just to crack a softwar

Firewalls can be divided into several different levels of security. In Linux, because there are many different firewall software to choose from, security can be low and high, the most complex software can provide almost impermeable protection capabilities. However, the Linux core itself builds a simple mechanism called "camouflage", which can withstand most attacks except the most specialized hacker attacks. When we dial a connection to the Internet, our computer is assigned an IP address that

1. Recently, for home routers frequently hacked, China Telecom issued an early warning: some hackers use the home wireless Broadband router using Admin/admin as the default username/password weaknesses, in some Web pages maliciously embedded in the home wireless broadband router to modify the DNS configuration code. The DNS address of a home wireless broadband router can be tampered with without the user's knowledge, as long as the user browses to the

Create a hidden account on the broiler for use when needed. Account hiding technology is the most hidden back door, the general user is difficult to find hidden accounts in the system, so the harm is very large, this article on the hidden account of hackers commonly used techniques to uncover. Before we hide the system account, we need to know how to view the accounts that already exist in the system. In the system, you can go to the command prompt,

How do you know where the leak is? "Of course it's easy to answer, because the bugs are in the code, but millions of lines of code who know where there are vulnerabilities. Well, what about this?

1. OverviewThis article analyzes in detail several sniffing devices that hackers often use in Linux, which are often planted on victim servers after being infiltrated by intruders. These sniffing devices have different characteristics. Some are simple to capture user names and passwords, while others are very powerful to record all network data streams. This article will analyze the following sniffer types:LinsnifferLinuxsnifferHuntSniffit2. linsniffe

At present, more and more users are using ADSL. Because ADSL users have been online for a long time and are fast, they have become the targets of hackers. Now there are various more and more detailed "IP address libraries" on the Internet. It is very easy to know the IP addresses of some ADSL users. How can we protect our network security? Take a look at the following methods. 1. Cancel folder hiding and sharing If you use Windows 2000/XP, right-clic

When we hear the word "hacker", we often think of complicated and mysterious technologies that only a few people in the world can execute.

Hackers may show off their "crazy skills", but these people are not what we really need to worry about. On the contrary, people with poor te

Deploy data leakage protection to reduce hacker "step-by-step" approaches Footprinting. For example, when thieves decide to rob a bank, they will not go in and ask for money directly (at least wise thieves will not ). On the contrary, they will have a hard time collecting information about the bank, includes the route and shipping time of an armed escort vehicle, camera location and camera range, number of cashiers, escape exit, and any other information that helps with the operation. The same r

Today, we will mainly tell you about reverse observation of server security configurations by hackers. Since our defense is from the perspective of intruders, first, we need to know the actual intrusion method of intruders. The following describes the specific solution and hope it will help you in your future studies.
