Computer security工作

I have full access to a PHP code-base that I can share immediately. I already know exactly which file and function contain a hidden back door; I just need a seasoned developer to: • remove every trace of that back door cleanly, • rebuild/package the application so it runs flawlessly after the fix, and • verify the change with a quick security review and functional smoke test. You’ll receive the source archive, a short note pointing to the suspect section, and the steps I normally use to deploy. Hand back the cleaned code, a brief changelog, and confirmation that the application still behaves as expected on a standard LAMP stack.

I need a seasoned security professional—someone who has actually pulled off successful penetrations and even full session hijacks in the wild—to give my external-facing network a thorough workout. The scope is strictly external; there is no internal, wireless, or cloud component in this engagement. The objective is simple: show me every door that an outsider could force open, prove it with clear evidence, and guide me through remediation. I’m not rushing this project, so you’ll have the breathing room to plan, execute, and re-test without cutting corners. What I expect you to cover: reconnaissance, vulnerability discovery, exploitation, privilege escalation, post-exploitation, and a concise yet complete report that includes proof-of-concept screensh...
