Start with the language to write a program that does not exist in the market.0x01 why NodeJs?
I personally love the JavaScript language, and what we are talking about today is NodeJS, a branch of the JavaScript language. NodeJS itself is a Web server and also a back-end language. This is especially important because we only need to download a NodeJs to complete a series of operations, which saves a lot of trouble.
I believe many of my friends have deleted the backdoor that has been infiltrated. Today I am writing this article to teach you how to create your own hidden backdoor and fight the Administrator ''''

Since I last found a WebShell management website from the Internet, I found a backdoor, infected with a Trojan, and the database was damaged. So far, it has not been repaired ...... So be especially careful with others' webshells.
I found a 13th WEBSHELL final generator on the Internet,

TIPS: in Windows xp, the "tasklist/svc" command will receive the same effect.
Due to the length of the article, all functions of Svchost cannot be described in detail. This is a special process in Windows. If you are interested, refer to the relevant technical materials to learn more about it.Next, we have used svchost.exe to launch the trojan program. Here, I chose PortLess

Cisco announced it would check whether the software contains backdoor code
After Juniper's firewall product NetScreen finds two backdoors, Cisco announced that it would re-examine its software in case it contains backdoor code. The backdoors of Juniper are considered to be hidden in the elliptic curve encryption algorithm, and the backdoors of Juniper are a secret password for managing access permissions.
