At present, the virus under the Linux platform is divided into the following 4 major categories:
(1) executable file virus, which can be parasitic in the file as the main object of infection of the virus.
(2) worm (worm) virus, Linux platform worm virus is rampant, such as the use of system vulnerabilities spread ramen, lion, slapper, and so on, these viruses are infected with a large number of Linux systems, causing huge losses.

Introduction
All security guides recommend you shoshould have a security audit toolkit (or forensic toolkit or recovery toolkit ). this toolkit is constituted by a set of static-linked binaries (grep, w, netstat, ls, nc, strace, ps... Etc). The problem it that these security guides tell you to build this toolkit but never show you how to do it (they just tell it can be really difficult ...). In this article I will explain why we need this toolkit then I will show how to build it.

In addition, in the protection project list, select the file association protection option to enable the TXT and EXE files and extended menus to prevent trojans from being started by modifying file associations.
There are several kernel-type Trojan rules in the protection project list. These rules are the basis for the trojan defense master to determine whether a proces
mean that free anti-virus software cannot work normally, but the operation of any form of anti-virus software may provide a false sense of security. Most paid packages are attached with additional security controls, such as software firewalls, anti-spyware, security password management, and rootkit protection. In modern malicious network environments, the threats to data and digital information have risen to an unprecedented level, and security contr
help remove Backdoor programs. In addition, according to Microsoft, Windows 8 will include enhanced security features.In addition to the Sysinternals and F-Secure security products mentioned above, there are also third-party suites that can remove Backdoor programs in Windows.For example, Sophos Anti-Rootkit has an installer that must be run manually. This program can interact more with users, but it scans the system more slowly. Another backdoor sca

the main purpose of intrusion:1. system intrusion for the purpose of show off technology.2. system intrusion for the purpose of obtaining or damaging confidential data in the system.3. system intrusion aimed at undermining the normal operation of the system or business.
What will be discussed later in this article is to discuss how to quickly restore systems that have been intruded by these three types of systems, and how to reduce the impact scope and severity of system intrusion. Of course, b

Some time ago, there were hackers' hands and feet in the "Photo exposure" Incident and the "relief video" during the earthquake relief period. They often used interesting things to attract victims, the so-called bait. I don't know, these superficial things often contain malware or even r

Avoiding new methods of Process Detection
By: fuzen_opA lot of effort has been made recently to detect hidden processes, even thoseHidden using dkom tricks. Some rootkit authors have fired back by unhidingOr unhooking when the detection software runs. This is valid, but IWant to concentrate on the algorithm used by the detection software. Let'S defeat them in the kernel, brains to brains, man to man. Let the Cold WarContinue.
