Social App Vulnerability Assessment Needed

I want a seasoned ethical hacker to probe Facebook, Instagram, and Twitter for weaknesses that could expose our users to data-breach risk. Your job is to run a full penetration test—reconnaissance, exploitation, and proof-of-concept—using industry-standard methodologies such as OWASP MASVS, Burp Suite, Metasploit, and custom scripts where appropriate. I will supply test credentials and any supporting documentation you request, then step back so you can simulate real-world attack vectors without disrupting production. Please respect each platform’s responsible-disclosure guidelines and document every action for traceability. Deliverables (all required): • Executive-level summary highlighting critical, high, medium, and low findings • Technical report detailing methodology, tools, evidence, and reproducible steps • Risk ranking and recommended remediation for each issue • Clean-up confirmation that no residual backdoors or test data remain Acceptance criteria: The report must demonstrate at least one verified data-breach pathway if it exists, or clearly justify its absence; it must be reproducible on my side using the steps you outline and must not violate any platform’s terms of service. Timeline is flexible within reason, but I value clear communication and staged progress updates. Let me know your estimated turnaround and any prerequisites so we can get started.
