Sécurité Informatique Jobs

I need focused, reliable technical support for my Windows-based machines. This isn’t an administrative or creative assignment—the job is purely about getting Windows to run smoothly and solving the nagging issues I’m facing right now. If you have deep, hands-on experience with Windows 10 and 11—whether that means taming driver conflicts, removing stubborn malware, repairing corrupted system files, or troubleshooting software that refuses to install—then you’re the person I want to collaborate with. You should be comfortable working remotely via tools such as TeamViewer, AnyDesk, or similar, and be able to walk me through anything that requires local action on my side. Solid knowledge of PowerShell, Windows Event Viewer, and common diagnostic utilities w...

I have a Cisco Catalyst Center (DNA Center) deployment running and I want to turn on—and fine-tune—“rogue-on-wire” detection only. The hardware is already online; what I’m missing is the exact configuration inside DNAC that will reliably flag any unauthorized device that plugs into my wired infrastructure and then surface those events in the dashboard and in e-mail alerts. Here’s what I need from you: • A live or recorded walkthrough inside Catalyst Center showing the menus, policy settings, and thresholds you adjust to enable rogue-on-wire detection. • Written step-by-step instructions so I can reproduce the setup in other sites. • Verification guidance—how to generate test events and confirm that DNAC is catching them (CLI co...

I’m looking for a seasoned systems administrator who can take full ownership of our server environment. My immediate priority is professional, round-the-clock server monitoring and maintenance coupled with timely security updates to keep every instance hardened and compliant. Day to day, you will watch over performance metrics, act on alerts before they affect uptime, and roll out patches or configuration tweaks without disrupting service. Clear documentation of all actions and a concise weekly health summary are essential so I can track what’s been done and why. To be considered, focus your bid on the depth of your experience with similar always-on production setups—mention the operating systems, monitoring stacks, and security frameworks you know best.

I want to tighten the overall security of my small-office network and the first step is moving from our current dynamic IP to a properly configured static IP address. Once that stable address is in place I need the surrounding network protection measures—firewall rules, intrusion-prevention tuning, and any router or gateway hardening—to be reviewed and optimised so we reduce attack surface and improve monitoring accuracy. Here is what I am expecting from you: • Coordinate the switch to a static public IP with my ISP (I already have authorisation and credentials). • Configure the router/gateway to use the new address, verify DNS and NAT settings, and confirm all devices are reachable as intended. • Audit existing firewall rules, apply best-practice hardenin...

I am looking for a seasoned security specialist who can run a full-cycle, OWASP Top 10–oriented penetration test on our web application. The engagement must cover information gathering, vulnerability verification, exploitation for risk validation, and finally a polished report. What matters most: • You are genuinely comfortable hunting for SQLi, XSS, CSRF, RCE, SSRF, business-logic flaws and similar issues. • All testing is performed directly by you—no re-outsourcing and no leakage of data, code or credentials. • Burp Suite will be the primary toolbox; if you prefer supplementing it with OWASP ZAP or Nmap, that is fine as long as the results remain consistent. • You can show prior enterprise-grade work or at least a sample report so I can assess d...

I have a 64-bit Windows executable (~14 MB, digitally signed, admin-level) that I am studying for an academic -analysis course. Detect It Easy flags it as “Generic [Strange sections]” with high-entropy compression and the file uses obfuscated section names such as .e{, kvs, .{r34f, .*ApG<K. From an initial inspection I expect a combination of compression, encryption and obfuscation, but I need the exact protection scheme confirmed and fully bypassed. Everything must be handled in a safe, isolated lab so the original signature and any potentially dangerous behaviour remain contained. What I need from you: • A completely unpacked, runnable version of the executable • All extracted payloads, resources and secondary components • A technical report that...

We are developing a Windows kernel-mode driver that supports both AMD and Intel platforms, with a specific focus on IOMMU (Input-Output Memory Management Unit) functionality.

Disclaimer from the poster: This project does NOT involve cheating, hacking, or any form of academic dishonesty. The software is exclusively for personal, educational interest and will be used only on my private computer. It is not designed for any destructive or malicious purposes. To scammers: Please do not waste our time. I will NOT release any milestone payments before the project is satisfactorily completed. All communication and work must remain on this platform—I will not move conversations to other messaging apps...
