Continuous Proactive Threat Hunting

Hypothesis-driven human-led hunts that surface adversaries living inside your environment before automated detections trigger — reducing dwell time to days, not months.

The Case for Proactive Threat Hunting

Automated detections are calibrated for known threats — advanced adversaries specifically design their tradecraft to operate beneath detection thresholds.

10 days

Global median attacker dwell time — but 25th percentile is still 2+ months for stealthy APTs

[Mandiant M-Trends 2024]

31%

Of threat hunt missions surface previously unknown attacker presence

[SANS Threat Hunting Survey 2023]

58%

Of intrusions detected by external notification rather than internal controls — indicating systemic detection gaps

Proactive Threat Hunting vs. Alert-Only Detection

Alert-driven detection models work on a simple premise: known-bad behaviour triggers a rule, an alert fires, an analyst investigates. This model fails against advanced adversaries who invest specifically in evading rules — using living-off-the-land binaries (LOLBins), legitimate remote management tools, and slow low-volume C2 communication designed to fall below detection thresholds. The 31% hunt mission success rate from the SANS survey reflects systematic detection gaps that rule-based systems never close.

Vyomerc's threat hunting programme operates on adversary intelligence, not rules. Hunters develop hypotheses based on specific adversary TTPs relevant to your sector, then systematically search for indicators of those behaviours in your telemetry — from memory artefacts and scheduled task anomalies to subtle DNS beaconing patterns. Each confirmed hunt finding is converted into a new detection rule, compounding your detection library with every engagement.

Vyomerc Threat Hunting

Alert-Only Detection

Detection model

Hypothesis-driven human analysis targeting adversary TTPs invisible to automated rules

Rule-based alerting — blind to unknown and novel attack patterns

Adversary coverage

38 tracked adversary profiles inform hunt hypotheses specific to your sector and technology stack

Generic rule coverage; no adversary-specific focus

Dwell time impact

Biweekly hunt cadence reduces advanced persistent dwell time from months to days

Dwell time limited only by rule evasion capability of attacker

Detection improvement

Every hunt finding converted to a new SIGMA detection rule for automated future coverage

No feedback loop; gaps remain after every missed detection

Operational Workflow

How the Engagement Executes.

[PHASE_01]

Adversary Profiling & Hypothesis Development

Sector-specific threat intelligence analysis identifying the adversary groups, TTPs, and attack patterns most relevant to your organisation — forming the basis for hunt hypotheses.

[PHASE_02]

Data Source Validation

Assessment of available telemetry sources against hunt hypothesis requirements — identifying log gaps, sensor blind spots, and retention issues that would prevent hypothesis testing.

[PHASE_03]

Structured Hunt Execution

Systematic hypothesis testing using structured hunt methodologies across endpoint, network, and identity telemetry, with memory forensics for APT-class persistence techniques.

[PHASE_04]

Finding Conversion & Reporting

All confirmed findings documented as SIGMA rules for automated detection coverage, with executive hunt reports covering adversary activity identified and dwell-time reduction metrics.

Technical Specification & Deliverables.

Hypothesis-Driven Methodology

ADVERSARY_TTPSTRUCTURED_HUNT

Hunts are structured around specific adversary hypotheses derived from current threat intelligence — not random telemetry review — with documented methodology and measurable outcomes per mission.

LOLBin & Living-off-the-Land

LOLBAS_DETECTIONLEGITIMATE_TOOL_ABUSE

Specialist focus on living-off-the-land techniques using Windows management tools, scripting engines, and remote administration software that evade traditional signature-based detection.

Hunt-to-Detection Pipeline

SIGMA_CONVERSIONDETECTION_ENGINEERING

Every confirmed hunt finding is converted to a maintained SIGMA detection rule, creating a compounding detection improvement flywheel with each engagement cycle.

Hunt Engagement

Find the adversaries your rules will never see.

We conduct an initial threat hunt scope assessment, identifying hypothesis candidates from your sector threat landscape and available telemetry before commencing a pilot hunt.
