2026 Attack Surface Management Index Reveals Critical Exposure Risks
Event summary
- Intruder's 2026 Attack Surface Management Index found 26% of organizations have exposed MySQL databases, a prime target for ransomware.
- The report analyzed data from 3,000 customers over the year ending March 2026, revealing significant variations in remediation times by industry and company size.
- Banks and retailers remediate exposures in 10-11 days, while insurance and pharmaceutical sectors take 40-50 days.
- Midmarket firms (251-5,000 employees) face disproportionate attack surface risks as they scale, with remediation times peaking at 56 days for larger organizations.
The big picture
The 2026 Attack Surface Management Index highlights the growing cybersecurity challenges in the era of autonomous AI models like Mythos. As vulnerabilities are discovered and exploited faster than ever, organizations must address exposed assets like MySQL databases and admin panels to prevent automated extortion attacks. The data reveals significant inefficiencies in remediation times across industries and company sizes, particularly for midmarket firms struggling with scaling infrastructure.
