My phone and Mac-based computer were recently compromised and I am seeing clear signs of unauthorized access, suspicious background activity, and some missing files. I need an experienced ethical hacker or cybersecurity specialist who can remotely examine both devices, identify every backdoor or malicious profile, recover any lost data where possible, and lock everything back down so I am fully in control again. Your work will involve a forensic sweep of macOS (and the companion phone, likely iOS) to trace how the intruder got in, remove any malware or configuration profiles they left behind, and then hard-harden the system—ensuring strong authentication, updated firmware, and airtight network settings. Please be comfortable using common incident-response tooling such as Wireshark, ...

I run a custom web application on an Ubuntu droplet at DigitalOcean. Although every obvious door is locked—UFW rules are strict, all unnecessary ports are closed, Fail2ban is active, and SSH keys have been rotated—crypto-miners keep finding a way in and even wiping my authorized_keys file. and they also remove the logs. I need a specialist who can dig deeper than the basics, trace exactly how the breaches occur, close those vectors for good, and leave the box fully hardened. Think kernel-level auditing, service isolation, intrusion-detection tooling, automated patching, and any other best practices you know work on Ubuntu in a cloud-VM context. Deliverables I must see before sign-off: • A concise report pinpointing the original compromise path(s) and the corrective...

I am preparing for the CompTIA Security+ certification and want targeted, exam-style tutoring that zeroes in on Network Security—specifically firewalls and VPNs. The goal is to master the current exam objectives, clear up any conceptual gaps, and build enough confidence to score well on test day. Sessions should be live, interactive, and paced to my schedule. I learn best when theory is tied directly to hands-on examples, so walking through real-world firewall rules, VPN configurations, and related packet-flow scenarios is essential. Explanations must stay aligned with the Security+ wording and depth so I recognize the phrasing when it appears on the exam. Deliverables: • A structured lesson plan broken into manageable milestones • Live tutoring sessions with screen-sha...

My personal blog runs on a standard LAMP stack and I want a clear, ethical snapshot of its current security posture. The focus is on preventing data breaches and blocking any avenue for unauthorized access; malware checks are welcome but secondary. Scope You will carry out a legally authorised vulnerability assessment that covers: • A surface scan of the domain and sub-domains, mapping open ports and exposed services. • Manual and automated testing against the OWASP Top 10, using tools such as Burp Suite Community/Pro, OWASP ZAP, Nikto, or similar. • SSL/TLS configuration review, confirming protocol versions, cipher strength, and certificate chain integrity. • Inspection of server and application misconfigurations that could lead to privilege escalation, credenti...

This project covers the end-to-end creation of a brand-new Local Area Network for our premises. The environment will serve daily operations for both computers and servers as well as our shared printers and scanners, so stability, speed, and clean segmentation matter. The scope begins with planning: assessing the floor layout, sizing the switch stack, deciding on cable runs, and selecting hardware that fits future growth. Layer-2 and Layer-3 configuration must follow best practices—think VLAN separation for user groups, QoS where printing traffic needs it, and a security baseline that shuts unused ports, enforces 802.1X, and applies sensible ACLs at the edge. During implementation, I expect neat rack work, labelled cabling, and documented configurations (Cisco-style CLI or equivalen...

I have several Cisco-based lab and production environments that need hands-on attention from someone who already feels at home with CCNA-level work. Over the next few weeks I’ll be refining network configuration, tightening security, and—most importantly—sorting out a few stubborn routing-protocol issues that keep popping up. Here’s the situation: • Network configuration needs polishing on a mix of Catalyst switches and ISR routers, including VLAN planning, trunking, and interface tuning. • Day-to-day troubleshooting consumes far too much time; I want clear root-cause analysis when links flap, routes disappear, or access lists misbehave. • Security hardening is overdue—standard ACLs are in place, but I need smarter filtering and a quick r...

I need help installing routers for a series of small communication-network rollouts. Each day’s route will be planned in advance, and the actual on-site work rarely exceeds one to two hours. Your role is straightforward: pick up the assigned router, travel to the client location, mount the unit, connect it to the existing cabling, confirm internet connectivity, then send me a quick photo and speed-test screenshot before leaving. The schedule is flexible as long as the job is finished on the agreed day; I issue payment weekly, starting at 25 000 ₽, and increase it for consistently smooth, on-time work. What matters most to me is punctuality—I’d rather reschedule than keep a client waiting—and complete honesty about any delays or technical issues you encounter. Basi...

I am looking for an experienced Security Consultant to work on an ad hoc or fixed monthly basis to oversee and strengthen multiple IT environments.
