Cloudflare Detects Millions of Attacks Following Critical PHP Zero-Day Disclosure.

Cyberattacks Surge into Millions Following Public Disclosure of Critical PHP Vulnerability

Cybersecurity and cloud network infrastructure provider Cloudflare has reported an exponential surge in global automated exploitation attempts following the public disclosure of a critical PHP core vulnerability. As millions of malicious requests hit servers worldwide within hours of publication, government agencies and enterprise financial institutions have initiated emergency shutdowns and patch operations to prevent infrastructure compromise.

Exploitation Spikes, Global Incidents, and State-Level Emergency Responses

• Exponential Exploitation Velocity Tracked by Cloudflare:

  • Pre-Disclosure Baseline: Cloudflare Chief Executive Officer Matthew Prince disclosed via X (formerly Twitter) that during the 10 hours leading up to the public vulnerability announcement, Cloudflare's global edge network detected only a few thousand probing attempts.

  • Post-Disclosure Acceleration: Within 45 minutes of public disclosure, automated scanning traffic escalated to tens of thousands of requests. The volume ballooned to hundreds of thousands within two hours, quickly surpassing millions of active exploitation attempts globally.

• European Government Portals and Public Services Disrupted:

  • Preemptive Service Suspensions: Municipalities and national government agencies across Europe executed emergency offline procedures, temporarily suspending public-facing web services and digital administration portals to apply security patches safely and audit system logs.

• Financial Sector and Japanese Government Countermeasures:

  • Mitsubishi UFJ Financial Group (MUFG): Japan’s largest financial institution temporarily suspended select online banking features and customer web portals to execute emergency security hardening measures and protect infrastructure from automated exploit scripts.

  • Japanese Treasury Directives: The Ministry of Finance of Japan temporarily shut down portions of its public web content and online services while implementing security upgrades across its hosting stack.

  • Prime Minister's Emergency Warning: Prime Minister Sanae Takaichi issued a formal advisory urging public and private sector web operators to conduct immediate audits of their PHP environments and apply official vendor patches without delay.
