A brief history of the development of gray Pigeon virus and its past life

Since 2001, grey pigeons have been judged by anti-virus professionals as the most dangerous backdoor procedures, and have caused a high degree of concern in the security field. 2004, 2005, 2006, Gray Pigeon Trojan for three consecutive years by the domestic major antivirus manufacturers selected as the year's top ten viruses, gray pigeons so famous, and gradually become the media and netizens focus. People in shock at the gray pigeon to the vast number of computer users of the harm, but can not help but ask, how the gray pigeon from a copy of other viruses began to develop into a very influential domestic ten viruses, and even the king of poison it?

Since 2001, the Gray Pigeon has experienced three stages, such as imitation period, rapid development period and national hacker era.

Imitation period (2001-2003)

2001, the domestic Internet gradually become popular, network virus is also accompanied by the development of the Internet is increasingly replacing the traditional sense of the virus, and to 2002 years, "E-mail", "Network download and browse" and other ways to spread the virus began to emerge in large numbers, Internet security becomes the focus of public attention

At the same time, with the popularization of the network, people have been able to work and study at home, Soho more and more people's favor. With the network we can use the computer on the other side of the city to control the computer, so that we do not have to spend a lot of energy in person to the computer room operation server, remote control management software is also born.

2002, remote control software has entered a mature stage, is a necessary tool for network management personnel. But at the same time, some malicious behavior of the remote control software (backdoor) also circulated in the Internet, which is the most famous in China is "glacier" Trojan Horse back door. "Glacier" was flooded at that time to control a variety of Web servers, after the hacker successfully captured a server, will be installed on the "Glacier" service, the 2002 China's 10 major viruses, ranked third.

The first time the Gray pigeon appeared is to imitate the "glacier." "Gray Pigeon" is the 2001, the use of Delphi writing, the earliest did not release the product, more is the attitude of technology research, the use of the source of the sharing of the Internet, still can be found in the "Gray Pigeon" earlier version of the source code. "Gray pigeon" in the presence of the use of the most discussed "bounce port" connection, to avoid most personal network firewall interception. "Gray pigeon" at that time was not known as the "Glacier", so only a small number of infections, but its open source of the way so that "gray pigeon" gradually increased the amount of transmission.

Gray pigeons appear after the source code open, so there are many different versions, as the service end of the hidden way to start, it has laid the status of its malicious backdoor Trojan, at that time, to Jinshan poison PA led most of the security manufacturers will be reported to the user and monitor the "Gray pigeon" service end are identified as "hacker program", and resolutely kill, To a certain extent, to curb the growth rate of gray pigeons.
