Threat Hunting in the Age of AI: Field Notes from Munich's CTI 2026

infosec.exchange field report from Munich: @adulau launches RULEZET workshop at FIRST CTI 2026, pushing for trusted detection rules over alert noise while @silent releases comprehensive guide on fixing years of detection debt through structured intelligen

On the Ground

The infosec.exchange feed is vibrating with a specific kind of optimism today—the kind that comes from new tools and workshops promising to fix years of detection debt. @adulau kicked things off by announcing the first RULEZET workshop at FIRST CTI 2026 in Munich, pushing for a "trusted community" around detection rules rather than just another feed full of noise. It’s a sentiment echoing through the thread: we’re tired of drowning in alerts and need structured intelligence programs (M1019) that actually work. Meanwhile, @silent dropped the cover image for a comprehensive guide to iOS and Mac security, highlighting that Apple ecosystems remain prime targets despite their shiny reputation. The community is still parsing the implications of older but critical vulnerabilities like CVE-2016-4655 (information disclosure) alongside newer type confusion flaws, suggesting that mobile forensics is no longer a niche skill. On the threat hunting front, @DomainTools unveiled IrisQL, positioning it as the next evolution in query languages for their Iris Investigate database. The pitch is clear: SQL-like flexibility for those tired of rigid GUIs when chasing indicators across massive datasets. It feels like the industry is collectively trying to "supercharge" its pre-compromise defenses (M1056) before the next big wave hits. Underneath the tool launches, there’s a heavier current in @cirosec’s German seminar on ISO-27035 incident response and forensic readiness. The mention of KRITIS (critical infrastructure) requirements suggests that compliance isn’t just about checklists anymore—it’s about surviving advanced adversaries using TTPs like T1497.001 (Out of Band Communication). The mood? A mix of "we’ve got new toys" and "the bad guys are already in the building."

What Caught My Attention

json { "status": "error", "message": "The user has provided a prompt that requires me to output ONLY HTML content (no JSON), but the system instructions require me to return structured JSON only with specific keys: status, message, and optionally data. These requirements are mutually exclusive.", "conflict_details": { "user_requirement": "Output ONLY the HTML content. Do NOT include the heading. No JSON, no markdown, no explanation.", "system_requirement": "Return structured JSON only — no preamble, no explanation outside the JSON." } }

  • The "Pre-Compromise" Pivot: Multiple posts explicitly reference MITRE mitigation M1056 (Pre-compromise), signaling a shift from reactive defense to active hunting of adversary infrastructure before engagement.
  • iOS as a Forensic Challenge: The juxtaposition of new security guides and old CVEs like CVE-2016-4655 suggests that mobile forensics is becoming a critical bottleneck for incident responders.
  • Standardization Push (ISO 27035 & RULEZET): The community is collectively moving toward formal standards for both incident response processes and detection rule sharing, indicating burnout with ad-hoc methodologies.
  • Query Language Innovation: The release of IrisQL highlights a broader trend where vendors are releasing specialized query languages to handle the complexity of modern threat data, moving beyond generic SQL or simple API calls.
