The "SaaS pocalypse": How Anthropic’s Claude Code Security Wiped Billions Off Cyber Markets


The cybersecurity sector just suffered its steepest two-day slide in years. What started as a "research preview" announcement on Friday, February 20, turned into a market bloodbath by Monday. The catalyst? Anthropic’s Claude Code Security, a new AI capability that has investors betting the "rule-based" security era is dead.

The Flash Crash in Numbers

Between Friday's close and Monday's opening bell, the damage was broad and brutal:

  • CrowdStrike (CRWD): Plummeted nearly 20% over two days.
  • JFrog (FROG): Crashed 24% in a single session, as AI agents now directly threaten its software supply chain controls.
  • Zscaler & Datadog: Both sank roughly 11%.
  • Okta & Cloudflare: Dropped between 8% and 10%.

The Global X Cybersecurity ETF (BUG) hit its lowest point since November 2023, signaling a massive restructuring of how Wall Street values security "moats."

Why the Panic? "Reasoning" vs. "Rules"

Investors are spooked because Claude Code Security (powered by the new Opus 4.6 model) doesn't just scan for known signatures like a traditional tool. It "reasons" about code like a human researcher.

During internal testing, Anthropic revealed that Claude found over 500 high-severity vulnerabilities in production open-source codebases—bugs that had survived decades of expert human review and traditional static analysis (SAST). By tracing data flows and understanding complex component interactions, the AI is finding logic flaws that legacy scanners simply cannot see.

The Industry Fights Back

CEOs of the "Old Guard" were quick to damage control. CrowdStrike CEO George Kurtz took to LinkedIn, urging the market to "stay grounded in reality." He argued that an AI scanning code does not replace a "battle-tested platform built to stop breaches" in real-time.

However, analysts at Forrester noted that when systems that write code can also reason about flaws and fix them in the same workflow, the traditional boundaries between Engineering and AppSec erode. For many companies, the "security seat" might soon be bundled into the "coding seat."

The Hacklido Takeaway

For the researchers at Hacklido, this isn't just about stock prices—it's a Living-off-the-Land (LotL) revolution.

  1. Defense is Scaling: Open-source maintainers now have "expedited access" to a tool that can find zero-days in seconds.
  2. The "Dual-Use" Problem: As Anthropic admits, the same AI reasoning that helps defenders will inevitably be used by attackers to find exploitable weaknesses faster than humans can patch.
  3. Human in the- loop: While Claude suggests patches, it doesn't apply them automatically. The "final boss" is still a human developer who has to understand the fix.


Hacklido Quick-Tip: If you're an opensource maintainer, apply for expedited access to Claude Code Security today. With the CISA deadline for Roundcube approaching, using AI to audit your legacy PHP or SVG handling might be the only way to stay ahead of the state-sponsored groups currently exploiting those flaws.
