    My Instagram profile was taken over and every standard recovery option seems to hit a wall. I have already gone through password resets, contacted Instagram support, and used my recovery email / phone number, yet the system now replies “account not found.” I need someone with a proven track record of reclaiming hacked Instagram accounts to guide the process end-to-end, deal with any appeals or identity verification that Meta may request, and hand the profile back to me in full working order. Once access is restored, I’d like brief guidance on locking the account down with stronger security settings to avoid a repeat incident. Deliverables • Verified, working login to the original account (posts, followers, and settings intact) • A concise post-recovery c...

    An employee’s mailbox was accessed by our current email administrator, who then sent a message under that person’s name. I need clear, defensible proof that the email originated from the administrator’s computer—not the employee’s. Your first task is a small-scale forensic investigation. Please extract and interpret the full header, trace the sending IP address, and correlate it with server or workstation logs so I can demonstrate that the message did not leave the employee’s PC. Accuracy and chain-of-custody notes are important because this material may be presented internally (and potentially to legal counsel). Once that is complete, I’d like to transition ongoing email and website management to someone trustworthy. Our stack is fairly typi...

    I’m preparing an in-depth research as a generalist piece on how today’s dark-web marketplaces and service hubs operate and, more importantly, how a non-specialist can reach them safely and document findings without crossing legal or ethical lines.

Here’s what I need from you: • A concise, step-by-step walkthrough of the safest way to reach current dark-web marketplaces and service directories, written so any security-aware generalist can follow it.
