GOOG Falls 2.6% to $386.77 as Google Confirms Thwarting AI-Crafted 2FA Zero-Day Exploit

Alphabet's GOOG shares dropped 2.59% to $386.77 and GOOGL fell 3.03% to $388.64 on May 12 amid investor concerns over Google's disclosure of thwarting an AI-driven zero-day exploit. On May 11, Google’s Threat Intelligence Group reported the first confirmed in-the-wild AI-assisted attack, where hackers used an AI model to discover a 2FA-bypassing flaw in a popular open-source web admin tool's Python script, blocking mass exploitation and patching with the vendor. GTIG warned of accelerating AI adoption by state-linked groups from China, Russia, and North Korea, echoing the IMF's May 7 AI-cyber risk alert, heightening scrutiny on tech and cybersecurity sectors.
