    I need to obtain hard-to-reach details—specifically the IP address, associated phone number, and any location-related information—linked to one particular Telegram account. Standard OSINT searches have already been exhausted, so I’m explicitly open to advanced, purely technical hacking techniques that dig directly into Telegram traffic or MTProto behaviour. If this is within your skill set, tell me how you would approach the task, which tools or exploits you prefer to leverage, and what minimal input you require from my side (e.g., username, recent message, session file).

    I need a custom-built screen-sharing application for Windows that feels as seamless as TeamViewer or AnyDesk but remains persistent even if the host user tries to remove or disable it.

Core capabilities I expect • Full remote-control of the host PC, including keyboard and mouse input, with smooth, real-time streaming. • Secure file transfer in both directions. • Single sign-on authentication so my team can log in with our existing identity provider rather than juggling extra passwords.

    My security cameras stopped showing live video and recorded footage on the monitoring app. The wiring and power seem fine, so I’m convinced the problem sits on the software side—likely a mis-configuration or corrupted firmware. I need someone who can jump in quickly, diagnose the software fault, and get every camera streaming and recording again without wiping my existing footage or settings. You should be comfortable with typical NVR/DVR interfaces, remote desktop tools, and updating or rolling back firmware when necessary. Once the feeds are restored, I’d like a short explanation of what went wrong and the steps you took so I can avoid the same outage in future.

Although the hardware is operational, I want to squeeze every last drop of performance out of it and harden the supporting security stack.

    Digital Chain of Custody for Forensic Evidence ​Concept: A system for police and legal teams to track digital evidence (logs, hard drive images, CCTV footage) without tampering. ​The Problem: In court, digital evidence is often dismissed because the defense claims it was tampered with after seizure. ​The Solution: When evidence is collected, a cryptographic hash (SHA-256) of the file is generated and stored on a Blockchain. Every time the evidence is "checked out" or viewed by an officer, a transaction is recorded. If the file hash changes even by one bit, the Blockchain rejects it. ​Tech Stack: ​Frontend: React.js or Flutter. ​Blockchain: Ethereum (Sepolia Testnet) or Hyperledger Fabric (for private permissioned access). ​Storage: IPFS (InterPlanetary File System) to store the a...

    I need a seasoned PHP security specialist to comb through an existing application, locate and remove every hidden backdoor, then harden the code so it stands up to malicious probing—SQL Injection is my top worry. Once the cleanup is finished, you’ll redeploy the patched build to my live PHP stack and confirm that all features operate normally under real traffic. A successful engagement means: • a brief, private report pinpointing each issue you discovered and how you neutralised it • a fully patched source tree returned to me, ready for version control • the application running stably on my server, with verification that the fixes prevent the SQL Injection vectors you identified Please come prepared with practical exploitation knowledge, the usual security ...

    I’m ready to roll out a brand-new Active Directory environment on Windows Server 2022 and need a specialist who can take the project from zero to fully operational. Scope of work • Install and harden Windows Server 2022, promote it to Domain Controller and create the new AD domain. • Join a small fleet (fewer than ten) Windows client PCs to that domain, confirming each machine authenticates without errors. • Enable auditing so I can see login and logout times, failed login attempts, and account-lockout events inside Event Viewer and, ideally, a simple consolidated report. • Configure Tally in LAN mode so every authorised user on the network can access our shared company data without glitches or file-locking issues. I’m looking for a clean, well-doc...

    JumpCloud PC Fleet Administration

    I run a small distributed team with fewer than ten PCs, all enrolled in JumpCloud. From here on, I want every workstation handled consistently—user access created or revoked in minutes, essential software kept current, and security policies applied without exception. Scope of the engagement • User account management: create, modify, suspend, or delete JumpCloud identities as staff join or leave. • Software installation & updates: push new apps, automate patching, and verify version compliance across Windows and macOS endpoints. • Security policy enforcement: apply and monitor password, screen-lock, disk-encryption, and other baseline policies through JumpCloud. Because no formal SOPs exist yet, the first milestone is to document a lightweight but complete...

    Fix SMTP 535 Authentication Error
    15 ore left
    Cont confirmat

    My PHP-based app suddenly throws “Expected response code 235 but got 535 – Authentication credentials invalid” every time it tries to send mail. I already updated the SMTP username and password, yet both LOGIN and PLAIN still fail. What I need from you is a rapid deep dive into the SSL/TLS handshake, the SMTP dialogue, and any server settings that might be blocking correct authentication. I’ll grant temporary access to the mail-sending config and stream live logs; I can also run telnet or openssl commands on demand so you can trace the exact exchange. Deliverables • Identify the precise cause of the 535 failure • Implement or walk me through the fix until a test message returns code 235 (success) • Provide the confirmed working host, port, e...

    Secure My WordPress Site

    Cont confirmat

    Project Overview I’m looking for an experienced WordPress developer to perform a forensic audit and cleanup of a site that previously used custom developer-created code and automation. After a hosting migration, the site experienced admin access issues, login loops, and plugin behaviour reverting unexpectedly. Hosting support stabilised access but confirmed that custom plugins and non-standard configurations existed and fall outside their support scope. An automated deployment mechanism has been removed, but I need confirmation that no residual scripts, hooks, or configurations remain that could overwrite files, revert settings, or affect admin access. Scope Audit custom plugins, theme code, and mu-plugins Check for role/capability filters and forced redirects As...

    My private server farm runs entirely on Windows Server 2019/2022 and I want a single, reliable point of contact to keep it both secure and resilient. Day-to-day, you will be hardening the network with advanced threat-detection practices—think real-time log analysis, strict firewall policy reviews, prompt patching, and well-documented incident response plans. All data protection flows through Veeam. I rely on daily image-level backups, off-site replication, and periodic restore tests, so you’ll need to stay on top of job success reports, storage consumption, and any failure remediation without waiting for me to ask. Support is part of the arrangement: when an issue or change request lands in the ticket queue, I expect timely follow-through and clear communication until closure...
