On the Ground
The air in Munich at CTI 2026 smelled faintly of stale coffee and desperate optimism for a "trusted" detection ecosystem. @[email protected] is trying to build one with RULEZET, pitching a collaborative repository that sounds like the community’s last best hope against rule fatigue, though I suspect we’ll just end up arguing over syntax in GitHub comments instead of writing detections.
The mood elsewhere was a mix of academic rigor and sales hype. German practitioners are doubling down on ISO-27035 as the holy grail for incident response—a seminar by @[email protected] promises to teach orgs how to pivot from chaos to forensics, though they conveniently skipped over the part where nobody actually has the bandwidth for that level of process in a ransomware attack. Meanwhile, @[email protected] is shouting about their new query language, IrisQL, which promises "deeper access" to threat intel—code speak for "we sold you a database, now we’re selling you the flashlight."
The technical chatter remains grimly familiar. We saw ASN @[email protected] flagging active scans in Kwai Chung, HK (AS9009), likely probing for those legacy buffer overflows that never seem to get patched on edge routers. It’s the same old game: attackers finding unpatched F5 BIG-IP systems while defenders try to learn dual-environment mastery—Windows and Linux—from @[email protected] via WhatsApp seminars. If you’re not hunting in both GUIs and CLIs by now, you’re already behind.
What Caught My Attention
RULEZET (Open Source Detection Framework)
@[email protected] is pushing RULEZET as a "trusted community" for detection rules, positioning it against the fragmented landscape of Sigma and YARA rule dumps. The tool aims to standardize CTI (Cyber Threat Intelligence) sharing across the ecosystem, mapping detections directly to MITRE ATT&CK techniques like T1497.001 (Tunneling: Web Protocols). In practice, this means defenders can query for specific tunneling behaviors without parsing inconsistent rule syntax. The framework differentiates itself by enforcing a "trusted" metadata schema—less of a free-for-all, more like a peer-reviewed journal for Sigma rules.
Use Case: A SOC analyst hunting C2 traffic over HTTP can pull pre-validated RULEZET rules that have already been correlated with MITRE T1497.001, saving hours of false-positive tuning compared to raw GitHub rule dumps.
CVE-2023-35078 (Ivanti EPMM Auth Bypass)
The community is quietly panicking about Ivanti Endpoint Manager Mobile, which suffered an authentication bypass allowing unauthenticated access to PII. This maps directly to MITRE T1190 (Exploit Public-Facing Application) and T1530 (Data from Cloud Storage Object), as attackers leverage exposed API paths to exfiltrate mobile device data or pivot laterally. The NIST control here is SI-4 (Information System Monitoring), requiring real-time analysis of audit records to detect unauthorized access attempts.
Trending Signals
- ISO-27035 adoption spiking in EU incident response: Multiple German-speaking handles are citing the standard as a "prerequisite," suggesting regulatory pressure is finally forcing orgs to document forensics workflows, even if they don’t execute them well.
- CISA KEV vulnerabilities (CVE-2021-27852, CVE-2021-22991) still being exploited in 2026: The same deserialization and buffer overflow bugs from 2022 are powering scans today—legacy infrastructure is the weak link.
- Multilingual security training (Windows/Linux dual focus): A signal that defenders need to operate fluently across GUIs and CLIs, as attackers increasingly use graphical interfaces for execution in ICS environments (MITRE T0823).
Worth Your Time
The Ungoverned Workforce: Cybersecurity Insiders Finds 92% Lack Visibility Into AI Identities — If you’re wondering why your threat hunting is failing, this report explains that 92% of orgs can’t see the AI agents now running malware in their networks.
Organizations Warned of Exploited Cisco, Kentico, Zimbra Vulnerabilities — CISA’s expanded KEV catalog confirms that old vulnerabilities (like the Ivanti bypass mentioned above) are still being weaponized; check your patch levels before you hunt.
Quiz: What's Manufacturing's Biggest Cybersecurity Crisis? — A grim reminder that if you’re running legacy ICS environments with GUI-based access (MITRE T0823), you’re likely the target of today’s ransomware campaigns.
