How to pivot from Suricata alerts to deeper investigation with Open NRD

🔍 Threat Hunting Beyond the Basics The built-in alerts in Defender for Endpoint and Sentinel are a solid foundation, but threat actors actively try to find ways to get around default configurations. When you stream Defender data into Sentinel, KQL lets you dig deeper and create hunts that surface activity others might miss: ✔️ Query registry changes that indicate persistence (e.g., Run/RunOnce keys) ✔️ Spot suspicious use of LOLBins like rundll32.exe or mshta.exe ✔️ Correlate endpoint anomalies with risky Entra ID sign-ins ✔️ Identify rare processes that only appear on a handful of devices The real value is in making those hunts repeatable: 👉 Write the KQL query → Validate the results → Turn it into a Sentinel rule → Automate with a playbook Pro tip: Start in Defender Advanced Hunting to refine your KQL queries, then scale them in Sentinel for broader coverage. #ThreatHunting #MicrosoftDefender #MicrosoftSentinel #KQL #SOC #CyberSecurity #EndpointSecurity #SIEM #EDR

You’ve got Suricata. You’ve got alerts. Now complete the picture. In Part 4 of our threat hunting series, we show how to bring it all together with Open NRD - from detection to decision. Learn how to: ✅ Apply context to prioritize Suricata alerts ✅ Reduce noise and focus on high-value investigations ✅ Take faster, more confident action in the SOC If you’re serious about threat hunting with Suricata, this post shows you how Open NRD helps you operationalize it at scale.

Persistence is where attackers gain staying power. Detecting it requires a deeper understanding of the subtle ways adversaries embed themselves to maintain access. Missing it can mean overlooking the very foothold that keeps them inside your environment. This Level 2 workshop on September 24 will challenge your hunting process and sharpen your ability to expose persistence in real-world conditions. You’ll: 🌟 Work hands-on with realistic telemetry that mirrors adversary activity 🌟 Apply structured hunting methods to uncover registry keys, services, scheduled tasks, and more 🌟 Leverage threat intelligence to build hypotheses and validate findings Everyone will leave with resources to support future hunts, and those who complete the final challenge will also earn the Threat Hunting – Persistence (Level 2) badge.

Myth #15: Recon is boring and optional. Fact: Strong recon is the foundation of successful bug bounty hunting. Most hunters don’t fail because of lack of skill, but because of weak recon strategies. Recon is where big payouts start – mastering tools, creative information gathering, and persistence gives you the edge over thousands of hunters. If you’re serious about bug bounty, don’t skip recon. It’s not optional — it’s essential. #CrawlSec #CrawlStart #BugBounty #BugBountyTips #BugBountyRecon #CyberSecurity #InfoSec #EthicalHacking

Good presentation by Deepwatch at #splunkconf25. It described how it's created a holistic lifecycle across threat intelligence, threat hunting, detection, and response. Shift left, risk reduction, fewer false positives, improved #MTTD and #MTTR. Interesting and impressive. #cybersecurity #infosec #Splunk #Cisco #Deepwatch #CTI #threathunting #threatdetection #incidentresponse

Proactive beats reactive when it comes to cybersecurity. Threat hunting helps organizations detect hidden risks before they escalate into costly breaches.

YARA Rules for Threat Hunting and Detection! This repository provides YARA rules that help detect specific offensive tools and other malicious activity during threat hunting sessions. The rules are organized into two main folders: • yara_rules: Broader detection rules with less focus on performance, requiring more triage and analysis. • yara_rules_binaries_strict: Optimized rules focusing on file types and sizes, offering higher fidelity but fewer detections. It also covers various aspects of threat detection and incident response, including offensive Security, DFIR (Digital Forensics and Incident Response), YARA Rules, Forensics Tools, Hunting, Threat Intelligence, and more.
