I have a TP-Link ER605 Gigabit router and two separate internet feeds—one Cable line and a Starlink connection. My goal is to squeeze as much speed as possible out of both links by setting up proper load-bonding and balancing, not just simple fail-over. Fewer than ten devices sit behind the router, but they regularly max out available bandwidth during HD video calls and large file transfers, so every extra megabit counts. What I need from you • Walk me through, or remotely complete, the full WAN configuration on the ER605, ensuring both ISPs are active simultaneously and traffic is intelligently distributed for higher aggregate throughput. • Fine-tune any necessary bandwidth-based or session-based policies so that speed-hungry tasks take advantage of both links without...

I am dealing with a coordinated campaign that has breached my phone, several email accounts, and even my car’s onboard system. The intrusions appear to be carried out by multiple individuals and have progressed well beyond anything I can contain by simply changing passwords, which is the only measure I have tried so far. I need a seasoned cybersecurity specialist who can: • Conduct a thorough forensic assessment of my mobile device, email environments, and the car’s infotainment/OBD network to confirm attack vectors and persistence mechanisms. • Lock down each surface—mobile OS hardening, secure email re-provisioning with robust MFA, and defensive re-flashing or segmentation of the vehicle’s CAN bus—while preserving admissible evidence. &bull...

I am looking for an experienced cybersecurity professional to help investigate and resolve a serious and ongoing security issue. Last month, multiple personal accounts (including WhatsApp and other social platforms) and devices were compromised. Since then, I have: Switched to new devices Reset passwords and secured accounts Enabled basic security measures Despite these steps, I still suspect unauthorized access or a persistent compromise. My data may have been exposed, or there may be an underlying vulnerability (malware, spyware, remote access, or account takeover method) that has not yet been identified. Based on certain indicators, I suspect the possibility of an advanced spyware infection (potentially similar to Pegasus), but I need a professional to properly verify, confirm, or r...

I’m looking for an experienced freelance on-site network engineer located in Indonesia who can jump in immediately. The first priority is to assess and stabilise an existing business network; additional optimisation or expansion tasks will follow once the core issues are resolved. To move quickly, brief me on your hands-on experience with routers, switches, firewalls, or wireless gear you’ve configured in similar situations and the results you achieved. The role starts as soon as we agree, so please respond today if you’re ready to begin right away.

Across my web applications, internal network infrastructure, desktop endpoints, company phones, and public social-media profiles, I need a full-scope security examination. The engagement must blend hands-on penetration testing with a structured security audit so that both technical weaknesses and policy gaps are captured in one clear deliverable. Scope • External and internal testing of web apps, network segments, desktops, mobile devices, and social-media assets • Manual and automated discovery using industry-standard tools such as Burp Suite, Nmap, Metasploit, Wireshark, Nessus, Kali Linux, and OSINT/social-engineering toolkits • Coverage of OWASP Top 10, SANS Top 25, common mobile attack vectors, and configuration hardening checks Deliverables • Comprehen...

My laptop just came back from the repair shop and before I put it back into daily rotation I want a thorough health check and a proper clean-up. What I expect from you • Run a complete hardware diagnostic on the battery and power supply, hard-drive / SSD, and the screen so I have clear confirmation that each component is stable and within spec. • Verify software health: check the operating system for errors, ensure all installed applications open and run smoothly, and confirm that security and antivirus protection are active, up to date, and scanning correctly. • Give the machine a careful physical cleaning—keyboard, vents, ports, and screen—so it looks and runs like new. • Provide a concise report of every test you performed, the tools you used (...

My Asus X1505Z, fitted with an M.2 SSD, is locked by BitLocker after a former employee enabled encryption and left without sharing the password or recovery key. I must regain full access to every file on the drive—there are no backups to fall back on—yet I would like the work carried out entirely through remote means. I do not have the PIN nor the recovery key for the laptop. The device was not a part of active directory and the person used his own Microsoft account. To my knowledge it is locked with PIN and TPM. I can allow remote access via Anydesk as i can boot it to Hiren or Medicat via usb. I am willing to obtain any required software in support of this recovery within reason (not more than the cost of the freelancer fee) If you have proven experience in Windows Bi...

I need help tightening the digital security around a growing library of photographs. My priority is data protection: the images must stay confidential, unaltered and accessible only to authorised users. Here’s what I’d like from you: • Assess the current storage workflow (local drives, cloud folders, backups) and identify vulnerabilities. • Propose and implement practical safeguards—encryption at rest/in transit, granular access controls, and tamper-evident measures. • Document every change so I can maintain the system long-term, including clear restoration steps if something ever goes wrong. If you have hands-on experience with secure photo archives, modern encryption standards (AES-256, TLS), and best-practice key management, I’d love to...

I need a seasoned ethical hacker to perform a full-scale security audit of one of my production web applications. The primary goal is to uncover code-level vulnerabilities—anything from insecure input handling to flawed session management—and provide a clear remediation plan. While the audit may touch on broader OWASP issues, I’m specifically interested in how the current codebase could be exploited and what exact fixes will close those gaps. Here is how I see the engagement unfolding: • Conduct a thorough review of the live application and its underlying source code, using industry-standard tools such as Burp Suite, OWASP ZAP, static analysis utilities, and any custom scripts you rely on. • Deliver a detailed report that ranks each finding by severity, expl...

My home internet service is active, yet the network itself still needs to be organised so every desktop and laptop in the house connects smoothly and securely. I already have the modem-router and cabling; what I need is a specialist who can: • configure the router for optimum Wi-Fi and LAN performance • join two desktops and three laptops (Windows and macOS) to the same SSID and shared file/print resources • enable a basic firewall on the router, confirm each device’s built-in protection is on, and suggest any further light-weight security steps • test speeds, resolve dead zones, and document the final settings so I can maintain them later I’m happy to discuss the brand and firmware of the router before you start, and I can be on a video call durin...
