Our organisation’s digital footprint has outgrown the piecemeal protections we put in place over the past few years, so it is time for a coordinated security overhaul.

Google has suspended all of my paid ad campaigns because their scanner detects hidden malware on my WordPress site. I don’t see obvious redirects, pop-ups, or performance issues, yet Google keeps flagging malicious links that I can’t locate. I need a specialist to dig in, eliminate every trace of the infection, and lock the site down so ads get re-approved quickly. You’ll have WordPress admin, cPanel, and database access. No security plugin is active right now, so you’re free to deploy whichever tools you trust—Wordfence, Sucuri, MalCare, CLI scanners—provided the end result is a clean, secure install that passes Google Safe Browsing. Deliverables • Comprehensive scan report detailing every infected file, URL, or database entry • Complete r...

I want a thorough, professional security check on two devices—one Android and one iPhone. I have seen unexpected apps or activities, rapid battery drain, and the occasional suspicious pop-up, so I need to confirm whether either handset has been compromised and, if so, understand exactly how to fix it. I have never sideloaded software outside the official stores, but I still want everything verified. Your task is to run a full forensic-level audit: scan for malware or spyware, inspect system logs for unauthorized access, review current privacy and security settings, and highlight every vulnerability you uncover. Please work only under my explicit authorization and within all legal boundaries. Deliverables • A clear, step-by-step report explaining findings for both devices &bu...

Web App & API Vulnerability Research I would like to assess your Web Application and API for security vulnerabilities that could affect your platform or its users, either now or in the future. The fixed pricing can be discussed later, as it will depend on the severity and impact of any vulnerabilities discovered. Critical vulnerabilities may require more effort than minor issues. Regardless of the findings, I aim to keep my pricing fair, affordable, and competitive. Best regards

My Gmail account was recently compromised and I’ve been locked out ever since. I already completed Google’s account recovery form, but the automated process has not restored my access. Time is critical and I need someone who knows the ins-and-outs of Google’s security workflow—device verification, backup codes, and support escalation—to get me back in as soon as possible. What I expect from you • Regain full, secure access to the account (inbox, Drive, and linked services). • Remove any unauthorized sessions or forwarding rules the attacker may have set. • Reinforce security with a fresh, strong password and two-factor authentication. • Provide a concise set of instructions so I can keep the account—and connected devices&mdas...
