Google Threat Intelligence Group identified and stopped the first AI-developed zero-day exploit targeting two-factor authentication systems. Cybercrime groups had planned a mass exploitation event using the vulnerability before Google's intervention disrupted the operation. The discovery signals a new phase in the AI vulnerability race.

Google Identifies First AI-Developed Zero-Day in Cybercrime Operation

Google has identified and stopped what it says is the first AI-developed zero-day exploit discovered in the wild, marking a significant escalation in how cybercrime groups are leveraging artificial intelligence

1

. The Google Threat Intelligence Group uncovered prominent cyber crime threat actors planning to use the vulnerability for a mass exploitation event targeting an open-source web administration tool

2

. The AI-generated zero-day exploit was designed to bypass two-factor authentication, allowing attackers to access victim accounts using only password credentials

How Researchers Detected AI in Cybercrime

Google's investigators identified several telltale signs that large language models assisted in exploit development. The Python script contained educational docstrings, a hallucinated CVSS score, and structured, textbook Pythonic formatting highly characteristic of LLM training data

5

. The 2FA bypass exploited a high-level semantic logic flaw where developers hardcoded a trust assumption in the platform's authentication system

1

. According to the Google Threat Intelligence Group, while frontier LLMs struggle with complex enterprise logic flows, they excel at contextual reasoning—reading source code to validate developer intention versus actual implementation and quickly identifying unconsidered corner cases

The AI Vulnerability Race Has Already Begun

John Hultquist, chief analyst at Google Threat Intelligence Group, emphasized that the AI vulnerability race is not imminent—it has already started. "For every zero-day we can trace back to AI, there are probably many more out there," Hultquist stated

4

. He challenged observers to focus on the bigger picture: if criminals are using AI in cybercrime, state-sponsored hackers with significant resources probably are too

3

. Google worked with the impacted vendor to responsibly disclose the vulnerability and disrupt the threat activity before the mass exploitation campaign could launch

Self-Morphing Malware and Autonomous Operations

Beyond exploit generation, AI in cybercrime has expanded to self-morphing malware capable of modifying its own source code in real-time to evade detection

2

. The PROMPTSPY Android backdoor leverages Google Gemini to autonomously navigate infected devices, taking screenshots and interpreting UI elements to simulate user interactions, including capturing PIN authentication and intercepting uninstall button clicks

2

. This malware demonstrates high operational resilience, allowing attackers to rotate critical components like command-and-control infrastructure and Gemini API keys at runtime without redeploying the payload

Expanded Threat Landscape Across Multiple Vectors

Google's report reveals pervasive AI usage across multiple cybersecurity operation types. North Korean group APT45 has been using AI to process thousands of exploit checks and expand its toolkit, while Chinese state-linked operators experiment with AI systems for vulnerability hunting and automated target probing

4

. Phishing campaigns now leverage bots to generate organizational charts and craft custom emails using real information from LinkedIn pages and press releases, with financial, internal security, and human resources departments serving as prime targets

2

. Russian influence operations have been detected using AI to generate believable voiceovers and subtly alter facial expressions in real video footage, interspersing fabricated content with legitimate news for disinformation campaigns

2

. Ryan Dewhurst, watchTowr's Head of Threat Intelligence, noted that AI is already accelerating vulnerability discovery, reducing the effort needed to identify, validate, and weaponize flaws—compressed timelines are today's reality, not a future concern
