    I hold written authorization from the system owner and need an experienced ethical-hacking professional to carry out a controlled breach of our production environment. The assignment goes beyond a traditional penetration test: I want you to replicate a real-world, end-to-end intrusion scenario so we can measure how our monitoring, logging and incident-response teams react under pressure. Scope • Obtain initial access using any non-destructive vector you discover (phishing simulation, misconfigurations, credential weakness, etc.). • Laterally move, escalate privileges and demonstrate data access without altering or deleting information. • Leave tamper-proof evidence (flags) in pre-agreed directories so we can verify compromise. • Conclude with a thorough report that det...

    I’m ready to move from concept to a fully functioning Wide Area Network and need an experienced networking specialist to guide every step. The job starts with assessing my current sites and bandwidth needs, then designing a scalable WAN topology that keeps latency low and uptime high. From there you’ll source or specify the right hardware, configure routing, implement security policies, test end-to-end connectivity, and leave me with clear documentation so my team can handle routine maintenance. If you’ve rolled out multi-site WANs before and can communicate technical details in plain language, let’s talk timelines and milestones.

    I need Cloudflare configured so my site automatically blocks malicious or nuisance traffic rather than legitimate visitors. The immediate headache is spam-driven form submissions and crawlers hammering the same pages hundreds of times a minute, so the goal is to stop those two behaviours without slowing genuine users. I already have a Cloudflare account in place; what I’m missing are the right firewall rules, bot management settings, and rate-limiting thresholds. You’ll review my current WAF/Bot Management setup, identify the loopholes that allow automated form posts and excessive page requests, then implement Cloudflare features such as Bot Fight Mode, custom WAF rules, Challenge or Turnstile for forms, and sensible request limits. Deliverables • Documented list of ...

    I’ve built a custom web application and it’s almost ready for production. Before the public rollout, I want a rigorous penetration test that will expose any weakness and help tighten every layer of security. The assessment must be hands-on and realistic, covering the full stack rather than a purely theoretical review. Scope My priorities are clear: • Code review – comb through the source for injection points, authentication flaws, insecure dependencies, and logic errors. • Network-level probing – map open ports, misconfigured firewalls, and potential lateral-movement paths. • Server configuration – evaluate patch levels, TLS setup, permissions, and hardening of the underlying OS and web server. Primary Goal The sole purpose is to imp...

    My iPhones and several smart-home devices have almost certainly been compromised. Unexplained behaviour, network slow-downs and repeated password lockouts suggest an active intrusion that I have not been able to stop remotely.

What I expect during the visit • A thorough forensic check of each affected iPhone and the smart-home hub/gear, including router or mesh nodes you judge relevant. • Immediate containment and removal of any malicious profiles, apps, firmware or network configurations you uncover. • Clear advice on whether each device can be salvaged or should be replaced, follow...
