I need support planning and configuring a pair of Hirschmann EAGLE40 firewalls that will run in transport mode at the edge of our industrial backbone. The goal is to gain precise control over internal business traffic, with carefully structured firewall rules and tight network-access control that fit the topology of our production network. You will start by reviewing our existing Layer-3 design and proposing how the EAGLE40s should be positioned, including any VLAN or routing adjustments required for seamless transport-mode operation. From there, I expect a complete rule set that segments departments, limits east-west traffic, and blocks any unauthorized protocols while leaving room for future growth. Network Access Control must be enforced through the firewall’s native feature set,...

A filesystem-focused incident lab on the TryHackMe platform is waiting for a clear, evidence-driven investigation. I have set up the room and just need the analysis, documentation, and incident-handling recommendations completed as quickly as possible. Scope of work • Access the assigned TryHackMe room (credentials will be shared after award). • Perform full file system analysis: recover artefacts, extract relevant logs, build a timeline, highlight persistence mechanisms, and identify the root cause of compromise. • Manage the incident virtually: detail containment, eradication, and recovery steps that flow naturally from your findings. Deliverables 1. A concise step-by-step walkthrough (commands, reasoning, screenshots where relevant) in PDF or Markdown. 2. An incid...

My primary Gmail address has been disabled by Google for “suspicious activity.” The only specific clue Google gave me is that there were unusual login locations before the shutdown. I still own the recovery phone and backup email tied to the profile, but the standard appeal form has so far led nowhere. I’m looking for someone who already knows Google’s account-recovery and appeal workflow inside out—someone who can draft the right responses, supply any required logs or headers, and walk me through additional verification steps so the mailbox, Drive, Photos, and linked services come back online without data loss. Selected red-flag Google detected: • Unusual login locations Desired outcome • Full re-activation of the Gmail/Google account ...

My production Windows server has gone silent—no RDP, no web console, nothing. I still hold full ownership credentials with the hosting provider, so authorized recovery options (rescue console, snapshot-based rollbacks, etc.) are available.

The core goals are simple: • Diagnose why the server is unresponsive and revive it through approved rescue or recovery tools • Regain normal administrator access without breaching provider policies • Audit current services, patch levels, startup items, and event logs • Implement practical hardening steps (firewall rules, updates, backup checks) and explain what was changed Please...

My Roblox account was taken over more than a month ago and every attempt I have made with the official support path has stalled. I opened a ticket, verified everything they asked, yet the agent eventually said my ownership “could not be verified” and closed the chat. I still cannot log in and the account shows activity that isn’t mine. I need someone who knows the inner workings of Roblox’s recovery process—escalation routes, proof-of-ownership requirements, and the exact language that convinces Trust & Safety to reopen a closed case. If you have previously restored accounts after long periods of compromise, or you maintain contacts who can push a manual review, you are the person I’m looking for. Your goal is simple: regain full access to my accou...

Our BGMI (Battlegrounds Mobile India) infrastructure occasionally freezes when traffic surges. I want to put a permanent stop to that by building a preventive DDOS shield that covers every critical touch-point—login, in-game communication, and matchmaking. You will begin with a quick audit of the existing network layout and traffic patterns, then design and deploy a solution that blocks volumetric and application-layer attacks before they can overwhelm the servers. I expect minimal additional latency for legitimate players, clean documentation of every rule or service introduced, and a repeatable playbook I can apply to new nodes as we scale. Deliverables • Security architecture diagram and written rollout plan • Hardened configurations applied to the login, game, a...

I need a seasoned ethical hacker to probe my public-facing web applications and surface every weakness before attackers do.
