Summary Points Cyberattacks are increasingly slipping undetected, with damage occurring within minutes, mainly through exploiting existing access points rather than system hacking. Identity-based attacks, especially involving passwords and legitimate account abuse, comprise 97% of incidents, with phishing, social engineering, and supply chain breaches remaining core threats. Business email compromise (BEC) accounts for over 70% of incidents, often lasting weeks undetected, frequently initiated through phishing. Ransomware, especially via RaaS and insider credential marketplaces, poses a major threat, with vulnerable sectors like industrial, construction, and logistics being primary targets. Key Challenge The report from Eye Security’s 2026 State of Incident Response reveals…
