I need a Godaddy-issued SSL certificate installed and fully configured on my Windows Server 2019 VPS that is also hosted with Godaddy. The certificate has already been purchased; what’s left is generating the CSR (if you prefer, I can supply one), importing the returned certs, installing the intermediate chain, and binding everything to the correct IIS site so the domain loads only over HTTPS. Once the certificate is in place, please force-redirect all HTTP traffic to HTTPS, check for mixed-content warnings, and run an SSL Labs test to confirm an “A” rating or better. Deliverables • CSR generation (or validation of my existing CSR) • SSL certificate and chain correctly installed in IIS • HTTP-to-HTTPS redirect enabled and verified • Final rep...

O Facebook Sharing Debugger devolve os códigos 418 e 429 para todas as URLs do meu site, impedindo que meus artigos e posts de blog sejam exibidos corretamente ao compartilhar. Os metadados Open Graph já estão configurados, portanto o problema está, muito provavelmente, na forma como o crawler do Facebook chega ao servidor (DNS, firewall, cache, rate-limit ou configuração de headers). Sua missão: • Diagnosticar a causa exata desses retornos 418/429. • Ajustar a configuração necessária — seja no servidor web, proxy/CDN, regras de segurança ou limites de requisição — para que o Facebook consiga acessar qualquer página sem bloqueios. • Validar, no próprio Sh...

I'd need to create a social network with , I'd need hardening plus ensuring the platform will be deployable and production-ready

My network edge relies on a Sophos XG appliance and a Fortinet FortiGate unit. Both devices are in production, but their current configuration is a mix of legacy rules and quick fixes that now interfere with performance and security. I want a seasoned firewall engineer to step in, examine every setting, correct what is wrong, and design a clean, least-privilege rule base. Scope of work • Configuration – back up the existing setups, remove or refine redundant rules, and align all interfaces, NAT, VPN, IPS and logging options with best-practice guidelines for Sophos SFOS and FortiOS. • Troubleshooting – identify and eliminate the intermittent drops we see on site-to-site VPN and outbound web traffic. Validation must include live traffic tests and log review. &bul...

My Magento store is currently flagged by Nexcess for possible malware. I have their scan report and need a hands-on specialist to manually confirm every alert, and clean the installation without breaking live sales. Work required • Perform a fresh, manual malware scan that follows the exact paths and hashes Nexcess identified. • Quarantine, repair, or safely remove every malicious or suspicious file, keeping clear records of each action. • Apply any missing Magento security patches and extension updates once the site is clean. • Verify front-end, admin panel, checkout, and cron jobs all run normally after remediation. • Produce a detailed PDF/Markdown report summarising findings, actions taken, and recommendations to keep the site secure. Acceptance cri...

I run a Canadian real-estate search engine that must stay lightning-fast for genuine home-hunters while remaining fully crawlable by Google, Bing and other reputable AI/search bots. Right now Cloudflare shows ±100 k daily hits from malicious, spam and scraper bots; that traffic spikes the servers, ruins bounce-rate metrics and occasionally knocks the site offline. I have already: • Placed the site on Cloudflare, • Allowed full, captcha-free access for visitors inside Canada, • Forced most other countries through a captcha, • Experimented with firewall rules, IP and UA blocking. Unfortunately, Google’s crawler activity drops whenever the shield becomes too strict, so I’m looking for an expert who can strike the sweet spot: block malicious...

I am looking for an experienced Instagram account recovery specialist to help me regain access to my business Instagram account. I currently cannot log in to my account through any method: Password reset is not working Facebook login is not working Instagram recovery page shows “No account found” However, the username and account are still visible when checked from another Instagram account Additional details: This is a business account I still have access to the original email and phone number The issue happened suddenly, likely due to hacking or unauthorized changes What I need: Proper recovery through Instagram / Meta official support Assistance with hacked account appeal and verification No fake tools or scams — only legitimate recovery methods Requireme...

My QRadar deployment needs a sharper eye on phishing. I want a set of custom Alert and Correlation rules that reliably pick up everything from the first suspicious e-mail event to follow-up user activity that hints the attack is moving forward. Scope • Build correlation logic that ties together indicators such as mail-gateway detections, odd mailbox rules, risky web clicks, and any subsequent authentication anomalies. • Create alert rules that trigger actionable offenses the moment a phishing pattern emerges. The rules must fit neatly into existing QRadar best practices: use building blocks where appropriate, keep AQL searches efficient, and document each rule so another analyst can tune or extend it later. Acceptance A rule set that fires during lab replay of know...

I’ve just migrated a collection of custom-built PHP sites to a new server. Each site lives on its own domain, yet they all share the exact same codebase and make the same calls to our captcha service. On the primary domain the captcha still validates perfectly, but every other domain now throws a failed-verification error. Key facts • Same captcha service and identical configuration on every site / each site points to the same web files • All domains have valid SSL certificates and load over HTTPS • No code changes were made during the move—only the hosting environment changed What I need 1. Diagnose why the captcha accepts on one domain yet refuses the rest. 2. Apply whatever code tweak, API key setting, DNS entry, or server-side configuration is requ...

I need a thorough, methodical security assessment of my production-ready web application. The goal is to expose any weaknesses before launch, demonstrate real-world exploitability, and give me a clear, prioritized plan for remediation. Scope • Full application security testing: authentication, authorization logic, input validation, business-logic flows, session management, server configuration, and third-party integrations. • Black-box techniques are fine, but I can supply test credentials for deeper analysis if that helps you reach code paths hidden behind login. • Industry-standard tooling such as Burp Suite, OWASP ZAP, Nikto, or your preferred commercial scanner is expected, followed by manual verification so I’m not just getting automated false positives. ...

I’m managing a law-firm website on WordPress and need a Scrum-savvy professional to guide a short, focused sprint that uncovers every problem and closes each one out. At the moment the homepage, service pages, and contact forms are suffering from slow load times, broken links, visible placeholder text, and several security red-flags my host keeps warning me about. Here’s how I’d like us to tackle it: • Kick off with a rapid discovery session, turning existing pain points into a clear, prioritised backlog. • Run one or two time-boxed sprints (your call after the audit) to deliver: – Sub-two-second load times across the affected pages – Fully working links and forms, no placeholder copy left behind – Core Web Vitals in the gree...

My web application was prototyped in Google AI Studio and is already live in a sandbox environment, but a handful of thorny issues are blocking the ability to launch the app live. I’d like an experienced web-app engineer to comb through the code, confirm it meets best practices, and then resolve filtering errors based on the monetization model. Additionally, I need to connect a payment gateway and validate that it works. I will grant access and share environment credentials as soon as we start. A concise change log, commented commits, and a short validation report explaining what you reviewed and why you adjusted it will be the acceptance criteria.

I have a Base44 application that is already coded for the web and I want it running on my own virtual private server. The VPS is up, secured, and ready—what’s missing is the actual deployment. Here’s what I need to happen: clone or upload the current codebase to the server, install any required dependencies, configure environment variables, link up the database and storage locations I specify, and then expose the app at my domain with an SSL certificate in place. Once everything is live, a short, clear README or set of notes on the steps you took will help me maintain future updates without guesswork. Acceptance criteria • Application loads over HTTPS at the domain I provide. • All existing features work exactly as they do in my local build. • Deplo...

A recently rebuilt Windows workstation needs a bullet-proof antivirus setup carried out over a remote session. The job begins with selecting an effective AV suite (I am open to your recommendation—Norton, McAfee, Kaspersky, or another best-in-class option) and continues through full installation, optimisation, and hardening. Key protection goals • Online banking: isolate browser sessions, enable real-time phishing & key-logger defences, and verify safe-transaction modules are active. • Confidential files: enforce on-access scanning, tune heuristic settings for maximum detection, and lock down local folders with password-protected vaults or encryption available within the AV. • Google Drive sync: ensure cloud-storage scanning is enabled, block malicious file ...

My Classic ASP site was recently overrun by a black-hat SEO attack that injected gambling-related links into pages crawled by Google. Since then I’ve noticed a dip in performance, repeated security warnings, and spam URLs appearing in Search Console. I can give you full server access, including IIS and database credentials, plus the security logs and scans already generated by our endpoint software. What I need from you is a thorough forensic sweep to pinpoint every entry point—whether that’s a compromised .asp file, a rogue include, or a polluted database field—and then clean it without breaking the legitimate codebase or content. Deliverables • Complete scan of site files, MSSQL/Access tables and IIS logs • Written report listing each malicious...

I run a production-level Windows server that now needs steady, professional care. The box is already up and live; what I need is someone who can step in and take over the routine work that keeps it healthy and secure. Your core responsibility will be ongoing maintenance—installing patches, checking logs, pruning obsolete services, and making sure performance never drifts. In parallel, I want proactive security updates: closing vulnerabilities quickly, hardening configurations, and documenting every change so there are no surprises later. A typical month might include: • Scheduling and applying Microsoft updates with minimal downtime • Reviewing Event Viewer and other logs for early warning signs • Updating firewall rules or IPS policies when new threats emerge ...

I have, 40-core machine with 1 TB of RAM that needs to be turned into a practical development box for my team. The goal is to have both Windows Server and Ubuntu Server installed side-by-side, each ready for daily coding, testing, and collaboration. Here’s what I need from you: • Plan and carry out the installation of the two operating systems, making sure they coexist cleanly (dual-boot, virtualization, or any proven approach you recommend). • Partition and configure storage so that each OS has ample, clearly labeled space. • Enable remote access for multiple developers, with sensible user and permission settings already in place. • Apply baseline security hardening and system updates so we start from a solid, up-to-date foundation. Once finished, I s...

My Server4You VPS has triggered an abuse report and I need a one-time, decisive intervention. The first order of business is malware removal—locating and eradicating any malicious code sitting inside the WordPress installs. While doing so, I also need you to pinpoint which site is behind the current XML-RPC and brute-force login traffic, disable XML-RPC wherever it isn’t explicitly required, and verify no backdoor scripts are left behind. You will receive root (or sudo) SSH access. Once inside, please: • Scan every WordPress instance and the underlying file system, remove malware, and patch obvious vulnerabilities. • Trace the origin of the XML-RPC abuse and stop it without breaking legitimate functionality. • Review cron jobs, tighten file and directory pe...

My WordPress site needs an urgent fix on two fronts. First, password-reset emails never reach users even though the site is configured with the WP Mail SMTP plugin. I need you to trace why the messages fail—whether that’s an SMTP authentication glitch, host restriction, or mis-routing—and make sure the reset flow works end-to-end, including successful delivery to common providers such as Gmail and Outlook. Second, bots are flooding the registration form. There is currently no CAPTCHA in place, so a solid anti-spam layer has to be added. I’m open to Google reCAPTCHA, hCaptcha, or any proven alternative you recommend. The spam accounts already created should be purged, and the loophole closed permanently without degrading the experience for legitimate users. Deli...

My web backend already handles real-time WebSocket traffic and device-to-server messaging, but the client management module now needs immediate attention. The current codebase shows signs of SQL injection issues and server misconfigurations, and an initial scan hints at possible backdoors. Here’s what I need you to do: • Conduct a full security audit across the PHP + MySQL stack (running on Apache in a XAMPP-style setup) as well as the Node.js WebSocket layer. • Isolate and remove any backdoors, patch every SQL-injection entry point you uncover, and fix configuration mistakes that could expose the server. • Redeploy the cleaned code on a fresh, standard Linux server image, migrate the database where necessary, and confirm that all WebSocket real-time features r...

I need a new subdomain created inside my Square space account so it points cleanly to , where all my online courses will live. has already supplied the precise CNAME and TXT records and I will pass those straight to you; they simply have to be entered without disturbing the rest of the zone file because other integrations are already running on the root domain. At the same time, I want my branded email address fully recognised by the CRM. That means adding or adjusting the accompanying MX, SPF, and DKIM records so outgoing messages authenticate and incoming replies land where they should. Deliverables • Subdomain resolves to the correct workspace over HTTPS and passes their custom-domain check. • Email records propagate, SPF/DKIM show “pass” in common tester...

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, encryptio...

I’m bringing a multi-layer system back online—a native PHP-MySQL web backend that drives a Node.js WebSocket service and a client-management console. Before launch, the entire codebase needs a deep security sweep, but the web backend is my first target. I suspect hidden backdoors and unpatched vulnerabilities; I need them located, removed, and the fixes thoroughly documented. There’s no existing audit playbook, so I rely on you to propose and carry out a full methodology that mixes code review, penetration testing, patching, and verification. The environment is classic XAMPP (Apache, PHP, MySQL/MariaDB) with a standalone Node.js layer handling real-time connections, so hands-on experience with that exact stack is essential. Deliverables • A concise audit plan out...
