We've all seen this movie before. Tech giant announces earth-shattering AI breakthrough. Press release quotes company executive making grandiose claims about "industry firsts" and "game-changing potential." Tech press dutifully amplifies the message. Rinse, repeat, cash checks.
This time, it's Google's Big Sleep AI agent, which allegedly discovered a critical SQLite vulnerability (CVE-2025-6965) just before threat actors could exploit it. "We believe this is the first time an AI agent has been used to directly foil efforts to exploit a vulnerability in the wild," proclaimed Kent Walker, Google's President of Global Affairs.
The claim is certainly bold. But after years of watching Silicon Valley turn incremental improvements into revolutionary breakthroughs, we're adopting a more skeptical stance. Is Big Sleep truly the cybersecurity game-changer Google claims, or just another well-orchestrated marketing campaign wrapped in AI mystique?
The Numbers Don't Lie—But They Don't Tell the Whole Story
Let's start with what we know. In 2025 there have been 0 vulnerabilities in SQLite. Last year, in 2024 SQLite had 1 security vulnerability published. This is remarkable, considering SQLite is one of the most widely deployed database engines in the world. For context, 22,254 CVEs (Common Vulnerabilities and Exposures) were reported by mid-2024, reflecting a 30% jump compared to 2023 across all software.
The SQLite project maintainers have been refreshingly honest about the vulnerability landscape. "Almost all CVEs written against SQLite require the ability to inject and run arbitrary SQL," they note, adding that "few real-world applications meet either of these preconditions." In other words, most SQLite vulnerabilities are academic exercises that don't affect real-world deployments.
This context makes Google's discovery more interesting—and more suspicious. If SQLite vulnerabilities are rare and mostly inconsequential, why were threat actors allegedly preparing to exploit this specific one? Google won't say who these threat actors were, which is convenient for a story that's impossible to verify.
Google's timing is impeccable. Companies using AI-driven security platforms report detecting threats up to 60% faster than those using traditional methods. Meanwhile, there was a 202% increase in phishing email messages in the second half of 2024 as attackers increasingly weaponize AI for malicious purposes.
Big Sleep represents Google's answer to this escalating AI arms race. By November 2024, Big Sleep was able to find its first real-world security vulnerability, showing the immense potential of AI to plug security holes before they impact users. The technology combines threat intelligence with advanced code analysis to identify vulnerabilities that traditional methods miss.
But here's where the narrative gets murky. According to Google's own blog post, "the company's threat intelligence group was 'able to identify artifacts indicating the threat actors were staging a zero day but could not immediately identify the vulnerability.'" So they knew something was coming but couldn't figure out what? This sounds less like prescient AI and more like good old-fashioned intelligence work with a technological assist.
Let's acknowledge the elephant in the room: Google has a vested interest in positioning itself as the AI security leader. With around 50% of executives believing GenAI will advance adversarial capabilities such as phishing, malware and deep fakes, demand for AI-powered security solutions is skyrocketing.
Google's announcement conveniently coincides with this summer's major cybersecurity conferences, where the company will undoubtedly showcase Big Sleep's capabilities. "Next month at DEF CON 33, the final round of our two-year AI Cyber Challenge (AIxCC) with DARPA will come to a close," Google notes in its blog post. The timing isn't coincidental—it's strategic.
The vulnerability discovery itself follows a familiar pattern. "We discovered the vulnerability and reported it to the developers in early October, who fixed it on the same day. Fortunately, we found this issue before it appeared in an official release, so SQLite users were not impacted." This was Big Sleep's first public discovery in 2024. Now, conveniently, it's prevented an "imminent" attack just as conference season begins.
While Google's claims are impressive, the reality of AI-powered vulnerability discovery is more nuanced. "The Future Outlook: Moving into 2025, we expect more vulnerabilities to be discovered faster, thanks to advancements in AI-driven vulnerability scanners." But this cuts both ways—if defenders can use AI to find vulnerabilities faster, so can attackers.
The race isn't just about discovery; it's about weaponization. "In 2024, 0.91% of all CVEs (204 out of 22,254) were weaponized—representing a 10% year-over-year increase." The vast majority of discovered vulnerabilities never become active threats. This raises an obvious question: if Big Sleep is so effective at finding vulnerabilities, why hasn't it discovered more of them?
Google's answer seems to be that Big Sleep is selective, focusing on vulnerabilities that are "known only to threat actors." But this creates a convenient narrative where every discovery is, by definition, critically important. It's unfalsifiable marketing speak disguised as technical achievement.
Don't misunderstand—Big Sleep likely represents genuine progress in automated vulnerability discovery. AI-powered security tools are becoming increasingly sophisticated, and Google's combination of threat intelligence with automated code analysis is theoretically sound.
But the company's claims about preventing an "imminent" attack strain credibility. Without more details about the alleged threat actors or the specific intelligence that tipped them off, we're left with a story that's impossible to verify but perfectly timed for maximum marketing impact.
The real test of Big Sleep's effectiveness won't be dramatic press releases about foiling shadowy attackers. It will be consistent, measurable improvements in vulnerability discovery rates across diverse codebases. Until we see that evidence, we'll remain skeptical of Google's grander claims.
In the meantime, maybe we should all get some sleep—preferably not the kind that comes with a marketing department attached.
