The Cisco Talos 2025 Year in Review highlights a concerning trend where speed and age collide, as attackers continue to exploit long-standing vulnerabilities in embedded dependencies like Log4j and PHPUnit. The landscape has been further complicated by the emergence of React2Shell and the use of Agentic AI, which significantly reduces the time-to-exploit for newly discovered CVEs.
This shift leaves defenders with shrinking reaction windows as attackers pivot toward exploiting identity-centric systems and network perimeter devices. The report emphasizes that controlling identity has become a primary objective for attackers, allowing them to bypass MFA and gain deep access to organizational infrastructure long before traditional patch cycles can close the gap.
