The Security Gap That Lets Attackers Walk Right In

The report recounts an incident in which attackers exploited an unpatched, internet-exposed phone system and unmonitored contractor endpoints to obtain credentials, move laterally, and ultimately encrypt a hypervisor with ransomware; it emphasizes that breaches often result from inconsistent deployment and enforcement of security controls rather than a single tool failure and provides five practical lessons (close implementation gaps, act on recommendations, segment aggressively, hold third parties to standards, treat MDR/MSSP as partners).
