Google has highlighted a persistent global surge in scams driven by transnational crime groups, including Chinese organized gangs, exploiting AI tools to scale phishing attacks via malicious texts, imposter calls, and fraudulent pop-ups. While no direct breach of Google’s systems was reported, **183 million Gmail passwords were exposed via infostealer malware**, and a separate compilation listed **394 million unique Gmail addresses** in breached credential datasets. These exposed credentials—often reused across platforms—pose severe risks due to Google’s dominance as a Single Sign-On (SSO) provider, powering 90% of SSO options on top websites. Compromised Google accounts enable cascading attacks on linked services (e.g., financial institutions, social media), with **86% of web application attacks leveraging stolen credentials for initial access**. The vulnerability stems from systemic password mismanagement (e.g., reuse, weak enforcement by websites) and the lack of passkey adoption, despite Google’s 352% yearly increase in passkey usage. Though Google advocates for passkeys to mitigate phishing and credential stuffing, the sheer volume of exposed Gmail credentials—combined with SSO’s broad attack surface—creates a high-risk scenario for mass account takeovers, financial fraud, and downstream breaches across interconnected platforms. The threat is amplified by AI-enhanced scams, with **57% of adults experiencing scams in the past year (23% losing money)**, signaling a systemic failure in traditional authentication security.
