Amazon security boss says crims abused max-security Cisco firewall flaw weeks before disclosure
Summary
Criminals exploited a critical vulnerability (CVE-2026-20131) in Cisco Secure Firewall Management Center software as a zero-day for over a month before Cisco released a patch. Amazon's security chief confirmed these attacks, noting that the attackers utilized a post-exploit toolkit known as Interlock.
IFF Assessment
This is bad news for defenders because criminals exploited a critical vulnerability as a zero-day, demonstrating their ability to bypass defenses and conduct attacks before patches are available.
Severity
Defender Context
Defenders should be aware of the risks associated with zero-day exploits and the importance of proactive threat hunting and rapid patching for critical vulnerabilities. The use of post-exploit toolkits like Interlock highlights the need for robust incident response capabilities to detect and mitigate advanced attack techniques.
