- Job Description: I am looking for a data recovery or cybersecurity professional to provide guidance on recovering access to a password-protected RAR archive that I created and own. The file contains my personal information, and I have lost the password. - Scope of Work: Provide legal, ethical guidance on password recovery methods for RAR files. Recommend software or techniques that can be used by the file owner to recover a forgotten password (e.g., brute-force, dictionary attack, mask attack). Advise on estimated time, hardware requirements, and success rates based on the RAR version and encryption type.

I need an experienced ethical hacker who can accurately trace the real-world IP and physical location associated with a suspected identity-theft incident on my platform. The objective is to gather verifiable evidence of where the malicious access originated so I can hand it to my legal and compliance teams. Scope of work • Analyse server and application logs I will supply (raw Apache/Nginx logs, Cloudflare records, plus limited VPN/proxy data). • Correlate timestamps, user-agent strings, and any packet captures to map each login back to its most probable exit node. • Bypass or reveal VPN, proxy, or Tor masking techniques when feasible, using OSINT, passive DNS, traceroute, WHOIS, Shodan, and similar tools. • Deliver a concise report that lists: – Conf...

I need someone currently inside Iran to run focused usability tests on our mobile VPN. The goal is to see how easily a first-time user can install, connect and navigate the app while under the real-world network conditions unique to the country. You will test the latest builds on both iOS and Android, paying close attention to two things: • Ease of use – How intuitive are the onboarding flow, server selection and connection status cues? • Performance issues – Connection speed, drop-outs, latency and any errors that appear while switching servers or using high-bandwidth apps. Deliverables I expect: 1. Screen-recorded walkthroughs of the first-time experience on each platform. 2. A concise report highlighting friction points, crashes, slow steps and sugges...

Hi I will share the details with the shortlisted candidates. Thanks

During a recent SIM-card swap I lost access to every document, photo, and video inside my WhatsApp Business chats. All chats still open fine on the same phone, but the attachments themselves no longer appear in the media gallery or within individual threads. Here is what I know so far: • The account is still active on the original handset. • Before the swap, chat backups were enabled to Google Drive and the phone also kept a local backup on internal storage. • I need the full set of files back—PDFs, images, and videos—and ideally placed back in their original chat context or provided in clearly named folders. Your task is to locate and restore every recoverable attachment, whether from existing cloud backups, hidden local copies, or forensic recovery ...

I need to back tracking phising code / malware from personal computer to determine the security risk caused by specific malware / phising code on mac

I need a seasoned ethical hacker to assess the security of our one-time-password (OTP) verification flow from end to end. The engagement is fully authorised and limited to our staging environment; no production traffic may be disrupted. Scope of the test • Probe OTP generation and validation logic for weaknesses or predictable patterns • Attempt request manipulation, parameter tampering, and replay attacks to gauge bypass potential • Evaluate rate-limiting and brute-force defences, including lockout and alerting mechanisms • Review session handling during the OTP step to spot fixation, hijack, or privilege-escalation vectors • Inspect related APIs and webhook calls for improper authentication, excessive data exposure, or logic flaws • Analyse pass...

I need an experienced ethical hacker to uncover every weakness that could be abused from the outside. My main objective is simple: give me a clear, evidence-based picture of how a determined attacker could break in so I can close those gaps before anyone else finds them. Scope – Your focus is remote exploitation. Treat the target as an unknown black-box and assume no internal access. – Feel free to use the full penetration-testing toolkit—Metasploit, Burp Suite, Nmap, custom scripts—whatever gets reliable, reproducible results. – Any vulnerability you discover should be demonstrated with a non-destructive proof of concept. Deliverables 1. Executive-level summary that ranks each issue by real-world impact and likelihood. 2. Technical report detail...

Basically i want to retrieve password of an realvnc username that has been recently changed by server.

I've attached the project PDF. It needs to be in Spanish and playable on an Android console (RetroidPocket 5) emulated with Nethersx2 Turnip. Please review the file and let me know if you can do would be good to have a .CHD file, but if that's not possible, an .iso file will do. The ISO version is in the document; I don't have any mod tools/files. The database is based on the 2005/2006 season. For the graphics, "PS2 Authentic" visuals are fine.

I have a desktop application that runs on Linux, and I’m seeing stability problems that need to be ironed out. The core task is to locate the root causes of the crashes and glitches, patch them, and then provide me with a clean, tested build that runs without unexpected errors. You’ll have full access to the current source code and any supporting files. I can reproduce the issues on demand, so I’ll share exact steps and logs as soon as we start. Once you’re in, I’d like you to: • Audit the existing codebase to pinpoint problem areas • Implement targeted fixes and document each change • Re-compile and test across common Linux distributions to confirm everything works as expected I’m open to whatever debugging tools or profilers you p...

I’m looking for an experienced cybersecurity instructor who can guide me through the full process of vulnerability assessment—from planning and scoping through reporting and remediation advice. My goal is to gain practical, job-ready skills, not just theory, so I’d like each session to combine short explanations with hands-on demonstrations and walk-through labs. We’ll cover topics such as: • Setting up and hardening a testing environment • Scanning and enumeration with popular tools (Nmap, Nessus, OpenVAS, etc.) • Interpreting scan results to identify true positives • Prioritising and documenting findings in a clear, professional report I already have a basic understanding of networking and operating systems; what I need is structured ...

I already have a Proxmox cluster running and the SDN feature enabled; what I do not have is the routing magic that ties several internal subnets together and hands them off cleanly to my external software firewall. Here is the core of what I need: • My routing protocol of choice is BGP, and I want every SDN-defined subnet announced through it. • Inside Proxmox I rely on Virtual Switches, VRFs and Security Groups. Each element must be configured so that traffic stays segregated yet routable as required. • The end result has to pass traffic end-to-end: VM ↔ virtual switch ↔ VRF ↔ BGP ↔ software firewall, with no asymmetric routes or hair-pinning. Acceptance criteria 1. All internal subnets are visible on the firewall via BGP and can reach the i...
