Why Manual IOC Enrichment Fails at Scale
The math behind alert volume, dwell time, and why adding analysts doesn't solve the enrichment bottleneck...
MITRE ATT&CK Mapping Accuracy: How We Measure It
Mapping an observed behavior to an ATT&CK technique is not binary. Here is how ThreatPulsar scores confidence and what the thresholds mean for detection engineers...
C2 Beaconing Detection: Jitter Analysis and Why Round Numbers Lie
Cobalt Strike default beacon intervals produce suspiciously regular traffic. Most detection rules look for this regularity — adversaries know it too...
Generating YARA Rules from Enriched IOC Clusters
When IOC enrichment returns a malware family association, a single file hash can anchor a YARA rule that covers the entire loader family. Here is the methodology...
Not All Threat Feeds Are Equal: How We Score Feed Quality
False positive rates, freshness decay, and coverage gaps vary significantly across the 40+ feeds in ThreatPulsar's library. Here is how we weight them...
Detecting Lateral Movement from Windows Security Events
Event IDs 4624, 4769, and 4776 are necessary but not sufficient for lateral movement detection. The sequence and timing matter as much as the events themselves...
STIX 2.1 and TAXII 2.1: A Practical Guide for SOC Teams
The standards exist. Most SOCs are not using them. Here is what STIX/TAXII actually gets you versus what the documentation implies...
Integrating IOC Enrichment into SOAR Playbooks Without Breaking Them
Adding enrichment steps to existing playbooks sounds straightforward. The failure modes are predictable and avoidable if you know where to look...
Measuring Alert Fatigue: Metrics That Actually Reflect Analyst Load
Mean time to detect is the wrong metric. It hides the enrichment bottleneck and makes a backlogged SOC look functional until it isn't...
Clustering Threat Actor Infrastructure: ASN, Registrar, and TLS Fingerprints
Shared ASN and registrar overlap is a weak signal. TLS certificate fingerprinting adds a second dimension. Together, they narrow attribution from noise to a plausible cluster...
Multi-Tenant IOC Isolation for MSSPs: What "Isolation" Actually Means
Most enrichment platforms claim tenant isolation. Few explain what is actually isolated and what is shared. Here is how to evaluate the difference...
DGA Detection: Entropy, N-gram Analysis, and Why Dictionaries Matter
Domain generation algorithms have been documented for 15 years. Detection rates have not kept pace because most analysts are looking at the wrong signal...
