IoC & Yara Rule Development
Custom detection rules crafted by threat intelligence experts.
ThreatGrid’s IoC & YARA Rule Development Service (IYRD) provides organizations with high-fidelity Indicators of Compromise (IoCs), YARA signatures, and detection logic built to identify malware, threat actors, ransomware families, and targeted attacks in your environment. These rules are tailored to your systems, use cases, and threat profile for maximum accuracy and minimum false positives.
Turn threat intelligence into precise, actionable detection rulesOur Service
ThreatGrid analysts analyze malware samples, threat actor TTPs, infrastructure, and campaign activity to develop IoCs and YARA rules that can be used across SIEM, EDR/XDR, email gateways, firewalls, scanning engines, and automated detection pipelines.
We produce handcrafted, tested, and validated rules designed for real-world operations.
Service Highlights
High-confidence indicators based on real attacker behaviorCustom IoC Generation
Includes IPs, domains, URLs, hashes, mutexes, registry keys, file paths, and behavioral patterns.
Detect malware variants and families with precisionYara Rule Creation
Rules built to scan endpoints, memory, emails, binaries, and file systems.
Reverse engineering to uncover unique detection traitsMalware Analysis for Rule Development
Based on static, dynamic, and behavioral analysis of malicious samples.
Identify adversary-specific artifacts and fingerprintsThreat Actor Pattern Detection
Develop rules aligned to attacker clusters, TTPs, campaign lures, and samples.
Rules tuned to your environment for reliable detectionFalse-Positive Reduction
Validation against internal datasets, whitelisting, and noise suppression.
Every rule aligned to a recognized techniqueMITRE ATT&CK Mapping
Ideal for audits, compliance, threat modeling, and operational maturity.
Production-ready rules, validated and mapped to real threatsDeliverables
Each engagement includes:
- Verified IoCs (structured JSON/CSV/STIX)
- Custom YARA rules (with tags, metadata & conditions)
- Malware sample breakdowns (optional)
- MITRE ATT&CK technique mapping
- Detection logic explanation
- Recommended deployment locations
- Test results and false-positive analysis
- Integration notes for SIEM/EDR/SOAR
Optional:
- Rule auto-update feed
- Version control & rule lifecycle management
- Threat hunting queries (KQL, SPL, SQL)
Generic detections aren't enough — targeted threats require tailored rulesWhy It Matters
Attackers evolve rapidly, and generic signatures often miss new variants or generate excessive noise.
ThreatGrid IYRD delivers:
- Accurate rules for real threats
- Better detection coverage
- Faster response and triage
- Stronger protection against targeted campaigns
- Lower false positives and alert fatigue
Custom-built IoCs and YARA rules give your security team an immediate detection advantage.
Ideal for SOCs, IR teams, MSPs/MSSPs, and malware analystsWho Benefits
Great for organizations that:
- Need accurate signature-based detection
- Regularly handle malware investigations
- Perform threat hunting at scale
- Manage a SIEM, EDR, or custom detection stack
