Agentic AI Reshapes Cybercrime and Defensive Options

🤖Agentic AI gives autonomous agents the ability to access external systems, gather information, and take actions within defined workflows, making routine multi-system tasks far more efficient for human operators. Cisco Talos warns this efficiency is already being mirrored in the cyber crime economy, including the first observed AI-orchestrated campaign in early 2025. While AI lowers barriers to entry and speeds operations for attackers, it is imperfect and still requires skilled instruction and human oversight. Defenders can respond by building their own agentic tools, deploying honeypots to engage malicious agents, and refining detection to stay ahead.

Snort3 Adds Severity-Based Rule Grouping for Flexibility

🔔 Cisco Talos has introduced a new Severity rule group for Snort3 in Cisco Secure Firewall, grouping detection rules by CVSS-derived severity tiers (low, medium, high, critical). Administrators can set coverage by time range — from the last two years up to all historical vulnerabilities — to balance detection depth and performance. This makes it easier to align rules with patch cycles, compliance needs, and organizational risk priorities while reducing manual tuning.
