Risks & Benefits of LLMs & GenAI for Platform Integrity, Healthcare Diagnostics, Cybersecurity, Privacy & AI Safety: A Comprehensive Survey, Roadmap & Implementation Blueprint (2506.12088v1)

Abstract: LLMs and generative AI (GenAI) systems such as ChatGPT, Claude, Gemini, LLaMA, and Copilot, developed by OpenAI, Anthropic, Google, Meta, and Microsoft are reshaping digital platforms and app ecosystems while introducing key challenges in cybersecurity, privacy, and platform integrity. Our analysis shows alarming trends: LLM-assisted malware is projected to rise from 2% in 2021 to 50% by 2025; AI-generated Google reviews grew from 1.2% in 2021 to 12.21% in 2023, with an expected 30% by 2025; AI scam reports surged 456%; and misinformation sites increased over 1500%, with a 50-60% increase in deepfakes in 2024. Concurrently, as LLMs have facilitated code development, mobile app submissions grew from 1.8 million in 2020 to 3.0 million in 2024, with 3.6 million expected by 2025. To address AI threats, platforms from app stores like Google Play and Apple to developer hubs like GitHub Copilot, and social platforms like TikTok and Facebook, to marketplaces like Amazon are deploying AI and LLM-based defenses. This highlights the dual nature of these technologies as both the source of new threats and the essential tool for their mitigation. Integrating LLMs into clinical diagnostics also raises concerns about accuracy, bias, and safety, needing strong governance. Drawing on a comprehensive analysis of 455 references, this paper presents a survey of LLM and GenAI risks. We propose a strategic roadmap and operational blueprint integrating policy auditing (CCPA, GDPR), fraud detection, and compliance automation, and an advanced LLM-DA stack with modular components including multi LLM routing, agentic memory, and governance layers to enhance platform integrity. We also provide actionable insights, cross-functional best practices, and real-world case studies. These contributions offer paths to scalable trust, safety, and responsible innovation across digital platforms.
