I have a small office network—fewer than twenty endpoints—that I want thoroughly examined for weaknesses. The immediate focus is a vulnerability assessment combined with a full network-security audit. Pen-testing isn’t required right now, but I would like the audit to be detailed enough that we could progress smoothly to active exploitation tests later if needed. Scope – Map every device and service, then scan using industry-standard tools such as Nmap, Nessus or OpenVAS. – Analyse configurations (firewall rules, router settings, shared resources, OS hardening) and identify misconfigurations or outdated software. – Provide a clear, prioritized remediation plan. Critical issues first, followed by medium and low-risk findings. – Conclude wit...

Yesterday I noticed that every message and folder in my Hotmail account had vanished after an unauthorized login. I have since taken back control of the mailbox and switched on two-factor authentication, but Microsoft support told me they are unable to restore the data. I still need those emails. I’m after someone who knows the ins and outs of / Microsoft 365 back-end recovery, server-side retention, and forensic mail restoration. If you can locate and reinstate the deleted items—whether through the Recoverable Items folder, legacy PST pulls, or other Microsoft recovery channels—and then harden the account so this can’t happen again, please let me know your approach and an estimated timeline. Acceptance criteria • All recoverable emails and folders resto...

I need a reliable person located in the United States who can keep my personal laptop safely at their place, plug it in to power, and turn it on once every day. There are no special tasks to run—simply boot it up, confirm it’s online through your regular, stable internet connection, and let it sit for a moment so remote services can sync. After that, you can shut it down again. What matters most is trustworthy, secure storage in a clean, smoke-free environment, and the discipline to power it on daily at roughly the same time. No dedicated network, VPN, or extra equipment is required on your side; a standard home broadband line is sufficient. If you can provide a safe spot, dependable internet, and consistent daily availability, let’s talk about the hand-off logistics an...

My phone and Mac-based computer were recently compromised and I am seeing clear signs of unauthorized access, suspicious background activity, and some missing files. I need an experienced ethical hacker or cybersecurity specialist who can remotely examine both devices, identify every backdoor or malicious profile, recover any lost data where possible, and lock everything back down so I am fully in control again. Your work will involve a forensic sweep of macOS (and the companion phone, likely iOS) to trace how the intruder got in, remove any malware or configuration profiles they left behind, and then hard-harden the system—ensuring strong authentication, updated firmware, and airtight network settings. Please be comfortable using common incident-response tooling such as Wireshark, ...
