Web Scanning: A Backdoor Troubleshooter - WebShellkiller
As a blogger, I have experienced a variety of harassment and abuse, including being implanted with a black chain, search engine keyword hijacking, and stolen administrator account passwords. Fortunately, in recent years, backdoors and Trojans have been more timely to discover (usually within one to two weeks), and they have not caused much damage or injury. However, what appalls me is that they are “very hard to detect.”
The special nature of Web backdoor Trojans is that they are generally in the form of “source” code, which makes our PC security software basically ineffective against them. As a result, I have to emphasize the importance of being cautious with tainted, unknown plugins, and themes. It is also essential to avoid uploading files to the web root directory, as this can prevent the death of the site.
Unfortunately, even with the best precautions, it is impossible to be 100% guaranteed against a backdoor Trojan invasion. This is because a hacker can hide a “Trojan horse” statement in the source code file, which can be “activated” and quickly spread after execution. Therefore, the most effective way to kill them is to remove the malicious code from the “source” file.
Introducing WebShellkiller
After using WebShellkiller for a few days, I have found it to be an excellent tool for detecting and killing Web backdoor Trojans. Its accuracy and speed are still very good, and it has identified several hidden backdoor Trojan classes in “Source File” on my blog.
What is WebShellkiller?
WebShellkiller is a web backdoor killing tool that not only supports scanning webshell but also supports scanning dark chain. It is a combination of multiple detection engines, using traditional regular match, analog performed, parameters of the dynamic analysis and monitoring techniques, webshell semantic analysis, feature analysis techniques to hide the dark strand, and intelligent detection model constructed based on machine learning based on the behavior pattern of webshell.
How Does WebShellkiller Work?
WebShellkiller uses a combination of conventional techniques and artificial intelligence technology, static and dynamic scanning analysis, to detect and identify known and unknown backdoor files on a website. Its detection rules have been optimized in version 3.3, greatly improving the webshell detection rate. It also supports keyword-sensitive detection of dark chain, allowing users to define their own sensitive words.
Using WebShellkiller
WebShellkiller is very simple to use, even for white owners. To use it, you need to download the software to your local computer and then scan the local computer site directory. After discovering a suspicious file, you can then perform the corresponding server-side file operations (such as deleting the file).
Safety First
It is essential to remember to backup your site regularly and ensure that the server is “pure” before trying any new plugins or themes. I strongly recommend that blog owners use WebShellkiller regularly to scan for backdoor Trojans and prevent disastrous consequences.
Conclusion
In conclusion, WebShellkiller is an excellent tool for detecting and killing Web backdoor Trojans. Its accuracy and speed are still very good, and it has identified several hidden backdoor Trojan classes in “Source File” on my blog. I strongly recommend that blog owners use WebShellkiller regularly to scan for backdoor Trojans and prevent disastrous consequences.
