Hi, I'm very interested in Your offer. I have over 10 years of experience as system admin for both windows and linux based systems. I also have over 10 years of experience in the field of security testing and security fixing. I know all about popular vulnerabilities:xss, sqli, rfi/lfi, csrf, owasp top 10 and more. I also know how to test for vulnerabilities in various web cms(wordpress, drupal, joomla, magento, and others) including php apps and custom cms. Other than webapps, I also know how to test servers for security. I have done website security testing, penetration testing and security fixing in the past. For more regarding my previous work please check my profile.
So, choose me and I can promise You that I'll complete this project on time and to Your standards; however, I'll need more details(as in do you already have the chatroom coded and just need me to edit the code to be vulnerable to xss attack? or do you just need xss attack string? and so on) so I could assess the scope of work and adjust my bid accordingly if needed.
Thank You for considering my bid and I'm looking forward to Your reply.
Cheers.
