Summary

Recent analysis indicates that nine out of ten major cyberattacks over the past two years did not exploit zero-day vulnerabilities. Instead, these significant breaches stemmed from common security failures such as compromised maintainer accounts, credentials stolen by infostealers, lack of Multi-Factor Authentication (MFA) on portals like Citrix, successful social engineering against developers, unpatched known CVEs, and exposed databases. These attack vectors are not new; they have consistently dominated breach data for a decade. The advent of AI-powered attack capabilities, including those used by security agents, significantly amplifies the exploitability and scale of these existing vulnerabilities, accelerating phishing campaigns and credential stuffing operations by orders of magnitude.

Key takeaway

For security leaders evaluating their defense strategies, prioritize operational security over chasing novel threats. Your teams should focus on robust MFA implementation, diligent patching of known vulnerabilities, and strict credential management. Ignoring these "boring" but critical areas, especially as AI scales existing attack methods, leaves your organization highly exposed to the most prevalent and damaging cyber threats.

Key insights

Most major cyberattacks exploit common, known vulnerabilities, not zero-days, with AI accelerating their scale.

Principles

• Operational security gaps are primary attack vectors.
• AI enhances existing attack methods, not necessarily new ones.

In practice

• Implement MFA across all services.
• Regularly patch known CVEs.
• Audit for exposed databases and shared credentials.

Topics

• Cyber Attack Vectors
• Operational Security
• Credential Harvesting
• Multi-Factor Authentication
• Artificial Intelligence in Attacks
