Attack Chains, Not Just Attack Surfaces: Why Testing Individual Techniques Misses the Point

Summary: A Hacker News piece argues that breach and attack simulation programs test individual techniques mapped to MITRE ATT&CK one at a time, while real attackers chain steps like phishing, credential harvest, privilege escalation, lateral movement and exfiltration. It cites Filigran's State of Threat Management report finding that 93% of security leaders suffered a business-impacting cyberattack in the past 12 months, 88% say AI is accelerating attacker movement once inside, and 84% point to siloed tools and disconnected testing as a main reason exposures go unnoticed.
What you should know: If 93% of organizations were breached in a year despite having validated defenses, the controls that passed their individual tests did not stop the sequence, and the 10% of exposures left untested may be the link that makes an attack path exploitable.
