My WordPress site is currently crippled by a hack that is causing unauthorized redirects, filling pages with spam, and throwing periodic 500 errors. I can still reach the dashboard, though many areas are greyed-out or throw “permission denied” messages, so deeper access (SSH, cPanel, or FTP) will probably be needed. No previous cleanup attempts have been made—everything you find will be in its original compromised state. I need a specialist who can: • Pinpoint and remove every piece of malicious code or file, whether it’s buried in the database, core, theme, or plugin folders. • Restore proper core files and update WordPress, themes, and plugins to their latest safe versions. • Reinstate full admin functionality so I’m no longer locked out...

I need an experienced CCTV operator who is completely comfortable working on a hybrid setup that mixes legacy analogue cameras with newer digital-IP units. Your day will be split between two main environments—indoor office buildings and surrounding outdoor public areas—so you should already understand the different lighting, privacy and incident-response challenges each space presents. Core responsibilities • Monitor live feeds in real time, flagging and escalating any security or safety incident the moment it appears. • Review recorded footage on request, pulling out clear, time-stamped clips and written summaries for management or law-enforcement use. • Keep the entire hybrid system healthy: run routine diagnostics, swap or configure cameras/DVRs/NVRs, and...

I’m rolling out a new crypto wallet and need a production-ready smart contract written for Binance Smart Chain. The contract has to handle full token management, cover all transaction handling logic, and include a built-in multi-signature layer for extra security. Here’s how I picture the collaboration: • Token management should support minting, burning, transfers, and allowances in line with the BEP-20 standard (or an equivalent custom approach if you believe a tweak would be safer or more gas-efficient). • Every critical action needs event logging so the front-end can surface real-time status updates to users. • Multi-signature approval must gate high-value actions such as owner transfers or contract upgrades. A simple n-of-m schema is fine as long as sig...

I need a seasoned cloud-security specialist to give my Oracle Cloud Infrastructure and Google Cloud Platform estates a thorough health check, then guide me toward a Zero Trust posture. First, you will assess both environments end-to-end—identity and access, network controls, data-at-rest and in-transit encryption, logging/monitoring pipelines, and workload configuration—mapping every finding to current best practice and the relevant CIS Benchmarks. Next, I expect a concise report that clearly separates quick-win remediations from deeper, strategic fixes. Each item must carry a risk rating, the exact remediation steps, and any references to supporting documentation or Terraform snippets where useful. Finally, translate the recommendations into a phased Zero Trust Network ...

I'm the founder of NILQuant, an independent record for NIL deals in college athletics. We're looking for a qualified, independent reviewer for a scoped technical review of our core verification engine before its first production release. Scope (summary; full scope attached): - Rebuild our PostgreSQL database from its migration files on your own machine and repeat our test suite and reproduction kit - Check append-only history, two-person release controls, fingerprinting (SHA-256), school-to-school data isolation and a scoped verification API - Test the hosted demo with six test accounts (no admin access) and try to break the controls - Confirm our outside timestamping and write-once storage settings - Written findings, one retest round and a signed scoped conclusion All data is...

Devo sottoporre la mia rete aziendale a un test di penetrazione esterno per individuare e correggere eventuali vulnerabilità prima che lo facciano i criminali informatici. Cerco un professionista della sicurezza informatica con comprovata esperienza in penetration testing su infrastrutture corporate. Il focus è esclusivamente sul perimetro esterno: firewall, VPN gateway, servizi esposti in DMZ e qualsiasi altra porta o applicativo accessibile da Internet. Mi aspetto che tu: • conduca la fase di information gathering e scanning (ad es. con Nmap, Masscan) • esegua l’exploitation controllata con strumenti come Metasploit, Burp Suite o analoghi, mantenendo traccia di ogni passo • rediga un report tecnico in italiano che includa: descrizione delle vuln...

I’m ready to launch a brand-new cryptocurrency with a fixed maximum supply of 10 billion coins and I don’t want to piggy-back on Ethereum, BSC or Polkadot—I need an independent chain built from the ground up. The core purpose of the coin is to power smart-contract execution, so the chain architecture, virtual machine and fee model all have to be optimized for that use-case. What I already have in mind • Tokenomics: 10 billion total supply, no more, no less. • A smart-contract–friendly environment that can rival EVM chains in speed and cost. • Room to evolve into DeFi utilities later on. Where I need your expertise I’m looking for end-to-end technical guidance and implementation: choosing or designing the right consensus layer, writing ...

My site is already live and collecting customer information, but the current safeguards are minimal. I need an experienced cybersecurity professional to focus exclusively on data protection: assessing the way customer details are stored and transmitted, closing any gaps you identify, and putting long-term controls in place so the data stays safe even as the site scales. What I expect • A concise risk assessment of my existing environment (server, database, APIs, third-party plugins). • Implementation of best-practice controls—end-to-end encryption (SSL/TLS), database hardening, access-control policies, secure backups, and monitoring or alerting tools you feel are essential. • A short validation report or penetration test summary confirming the fixes are effectiv...

My Shopify store needs a thorough tune-up. I’m looking for someone who can run a complete security and performance audit, then tackle the specific problems I’m facing: • Security: I’m worried about virus or malware infections, possible unauthorized access and any avenue for data breaches. I want the store scanned, cleaned and hardened without disrupting day-to-day trading. • Performance: page-speed has dipped; I’d like clear recommendations and the quick-win fixes implemented. • Metafield cleanup: there are piles of legacy metafields from old apps. Please identify what’s safe to delete and tidy them up so the theme and admin stay lean. • Theme maintenance: several theme sections throw “block reference” errors after a rece...

I have a complete code-base that now needs to live on a cloud server. The immediate goal is twofold: 1) install and configure the application so it runs reliably in the cloud environment I provide, and 2) comb through every file, dependency, and configuration to confirm there are no hidden backdoors, malicious packages, or insecure default settings left behind after development. I’m deploying to a cloud server (provider is flexible, so please be comfortable with AWS, Azure, or GCP). You’ll set up the runtime stack, handle environment variables, connect the database, and push the first production build. While doing so, perform a thorough security audit: manual inspection, automated scanners, and any static-code-analysis tools you trust. If something suspicious appears, docu...
