HookWorm Stealth is an old PHP Backdoor just like c99Shell created by Justin Klein Keane as Proof of concept.

HookWorm Stealth provides less features than c99Shell but it’s activity can’t be track easily like c99Shell. it uses Cookies to leave no TRACE in Web server access log.

HookWorm Stealth PHP Backdoor Features :

  • Find .htaccess
  • Find open ports on remote system
  • Search for writable files or directories
  • and many more.

Download HookWorm Stealth from  http://www.madirish.net/sites/default/files/hookworm.php.tar.gz

When you get access of remote web server SHELL, the access log of web server will throw /index.php 200 OK status code that’s a normal good HTTP request.

Netsparker – False Positive Free Web Application Security Scanner

Netsparker- False Positive Free Web Application Security Scanner

False-Positive Free

All web application security scanners report false-positives, which means they report vulnerabilities that don’t exist.

Netsparker will try lots of different things to confirm identified issues. If it can’t confirm it and if it requires manual inspection, it’ll inform you about a potential issue generally prefixed as [Possible], but if it’s confirmed, that’s it. It’s a vulnerability. You can trust it.

Netsparker confirms vulnerabilities by exploiting them in a safe manner. If a vulnerability is successfully exploited it can’t be a false-positive. Exploitation is carried out in a non-destructive way.

Technical Details

When Netsparker identifies an SQL Injection, it can identify how to exploit it automatically and extract the version information from the application. When the version is successfully extracted Netsparker will report the issue as confirmed so that you can make sure that the issue is not a false-positive.

Same applies to other vulnerabilities such as XSS (Cross-site Scripting) where Netsparker loads the injection in an actual browser and observes the execution of JavaScript to confirm that the injection will actually get executed in the browser.
