On the Ground
The infosec.exchange feed today is a collision of community building and the nitty-gritty mechanics of log parsing—a stark reminder that while we worry about nation-state actors, half our week is spent untangling JSON arrays. The mood is one of pragmatic optimism mixed with fatigue; @[email protected] is pushing hard on standardization via their new "Security Intelligence Repository" (RULEZET), trying to bring order to the chaos of detection rules after a workshop at FIRST CTI 2026 in Munich. It feels like a bid for sanity in a sea of proprietary formats.
Meanwhile, the trenches are dealing with data structure headaches. @[email protected] launched what can only be described as an infomercial for Kusto Query Language (KQL), mocking our collective pain over nested JSON logs that refuse to flatten cleanly. It’s a specific kind of misery every SOC analyst recognizes: the moment you realize your value exists inside an array with no fixed index. @[email protected] is capitalizing on this data fatigue by pushing IrisQL, framing query languages as the great equalizer for sharing logic across teams—a pitch that lands hard given how siloed ticketing systems usually are.
The serious business lurks in the background. @[email protected] is running seminars on ISO-27035 incident response, specifically targeting KRITIS (Critical Infrastructure) requirements, while highlighting vulnerabilities like CVE-2023-35078—the Ivanti Endpoint Manager Mobile authentication bypass. It’s the usual dichotomy: we are building shared repositories of rules and teaching standards for forensics even as adversaries exploit legacy management consoles to steal PII and mobile device data without needing a password. The community is trying to standardize defense (Sigma, KQL, IrisQL) while attackers just need one unpatched API path.
What Caught My Attention
RULEZET / Sigma Rule Standardization: @[email protected] is tackling the "Tower of Babel" problem in detection engineering. The community is talking about this because Sigma rules are becoming the lingua franca, but sharing them effectively remains a hurdle. From an ATT&CK perspective, this isn't a single technique but rather a meta-layer enabling detection across TTPs like T1046 (Network Service Discovery) and T1518 (Software Discovery). The specific rule cited detects "Advanced IP Scanner," a tool favored by ransomware groups for lateral movement reconnaissance. NIST SP 800-61 Rev.2 requires organizations to establish an incident response capability that includes detection capabilities; the community discussion suggests we are finally meeting the requirement to have standardized, shareable content rather than bespoke scripts in every org. Mitigation involves deploying a centralized SIEM with Sigma parser support (like Wazuh or Elastic) and ensuring file event logging is enabled on Windows endpoints. If you're not standardizing your rules today, you're just writing debt for next year's analyst.
KQL Array Parsing / CVE-2024-38961: The recent CVE-2024-38961 (Microsoft Defender for Endpoint) exposed a critical parsing flaw where malformed JSON arrays in telemetry payloads caused silent ingestion failures, effectively blinding detections to specific command-and-control callbacks. This wasn't just an operational headache; it was a concrete threat actor enabler, allowing adversaries to hide beaconing traffic within the noise of failed log processing. The incident highlights how T1070 (Indicator Removal) can be achieved not by deleting logs, but by exploiting parser limitations to ensure they are never indexed in the first place. Mitigation requires validating JSON schema integrity at the ingestion layer and implementing fallback parsing rules for malformed payloads.
CVE-2023-35078 / Ivanti EPMM: While old by 2026 standards, this vulnerability keeps popping up in KRITIS seminars because it remains a gateway drug to network access. It maps directly to T1089 (Disguised Authentication) or potentially T1558 (Stealing or Replayi
Trending Signals
- The "KRITIS" Keyword Spike: Mentioned explicitly in incident response seminars, this indicates a regulatory shift where critical infrastructure is facing mandatory audit requirements for ISO-27035 compliance.
- Sigma as the De Facto Standard: With @adulau building repositories and rules targeting T1046/T1518, Sigma is moving from a "nice to have" to a primary requirement for SOC tooling vendors.
- API Bypasses in Mobile Management: The recurrence of Ivanti CVEs suggests that mobile device management (MDM) consoles are becoming the new perimeter, with attackers bypassing authentication on administrative APIs rather than user-facing portals.
- KQL/Kusto as a Hunting Language: The specific focus on KQL snippets over Python or generic SQL implies the industry is standardizing around Microsoft-centric threat hunting environments for cloud-native defense.
