U.R. (5321)Use NIST AI RMF to structure an AI security watchlist
Use the NIST AI Risk Management Framework to build an AI security watchlist tailored to East Asia cyber and AI risk monitoring. Map signals to governance owners, define evidence thresholds, and separate research digests from operational signals using flexible, source-grounded steps.
Building an Internal Patch-SLA Queue from Korea KISA/KrCERT Vulnerability Notices: A Practical Workflow Guide
Organizations can transform Korea KISA/KrCERT vulnerability notices into an auditable internal patch-SLA workflow by establishing clear triage steps, ownership rules, severity interpretation, exception tracking, and integration with existing vulnerability management systems—without imposing rigid thresholds or inventing unsupported procedures.
Map an East Asia incident write-up to MITRE ATT&CK without overclaiming
This tutorial guides security teams in East Asia and globally on how to map public incident reports to MITRE ATT&CK techniques while preserving uncertainty, avoiding unwarranted attribution, and maintaining evidence traceability. It provides step-by-step workflow guidance for analysts, threat intel teams, and incident responders to use ATT&CK as a neutral taxonomy for structuring findings without inflaming confidence beyond what the source supports.
What to extract from a ransomware leak post without amplifying it
This checklist guides security teams in East Asia and globally on how to extract verifiable, low-risk intelligence from ransomware leak posts—focusing on entity identifiers, proof types, data categories, verification steps, and clear escalation paths—while avoiding amplification of unverified claims or harmful re-sharing.
Combine EPSS and KEV to prioritize CVEs without panic
This workflow guides East Asia security teams on using FIRST’s EPSS model and CISA’s KEV catalog to prioritize CVEs without panic, explaining EPSS as a probability-based exploit predictor, when KEV confirms active exploitation, and how to document exceptions in vulnerability management processes.
Use the CISA KEV catalog to build an East Asia supplier patch watchlist
This practical tutorial guides security teams in using the CISA Known Exploited Vulnerabilities (KEV) catalog to create a focused, actionable patch watchlist for East Asia-based suppliers. It outlines steps to map KEVs to supplier software inventories, assign ownership, set flexible escalation thresholds, and maintain evidence records—without relying on numeric thresholds or rigid schedules.
Identity Dark Matter Exposes Critical Gaps as Enterprises Rush to Deploy Agent AI
Orchid Security’s Identity Gap Snapshot 2026 reveals that unmanaged ‘identity dark matter’ now constitutes 57% of enterprise identity footprints, creating systemic risks as Agent AI adoption accelerates without corresponding identity governance improvements, enabling autonomous systems to exploit orphaned accounts, excessive privileges, and locally managed nonhuman credentials.
GovCERT.HK Confirms Active Exploitation of Trend Micro Vulnerabilities Across Apex One and Vision One Platforms

The flaws enable remote code execution, privilege escalation, information disclosure, and tampering, affecting both on-premises and SaaS deployments. Immediate patching is required to mitigate elevated cyber attack risks.
ASEC Weekly Report Flags Ransomware on Nova and Dark Web Code Leak Claims in South Korea
ASEC’s Ransom & Dark Web Issues report for week 3 of May 2026 details a ransomware attack on South Korean cosmetics firm Nova, alleged data leakage from an open-source visualization platform attributed to CoinbaseCartel, and claimed source-code theft and sale from a developer platform by TeamPCP, based on AhnLab TIP monitoring.
Microsoft Neutralizes Fox Tempest Infrastructure Abusing Artifact Signing for Global Ransomware Campaigns
Microsoft’s Digital Crimes Unit has disrupted ‘SignSpace,’ a prolific malware-signing-as-a-service operation run by the threat actor Fox Tempest. By weaponizing Microsoft’s own Artifact Signing system via stolen identities, the actor provided valid digital certificates to ransomware groups including Vanilla Tempest, Akira, and Qilin, allowing malicious payloads to bypass enterprise security controls globally.
