Hunt APT Groups with
Firsthand Actor Intelligence
Effective APT hunting requires knowing who you're looking for before you start. ThreatBook researchers discovered and named SilverFox, a sophisticated APAC-origin APT group that evaded Western vendors entirely. ATI profiles 2,000+ adversary groups with campaign-level TTPs and MITRE ATT&CK mapping, not just IOC lists. TDP provides the network side: full traffic analysis, compromised host detection, and zero-day detection. ThreatBook's APAC coverage is firsthand research since 2015, not third-party aggregation.
APT Hunting Fails Without
Knowing Who You're Looking For
APT groups targeting APAC organizations operate with patience, discipline, and infrastructure that rotates faster than most intelligence feeds can track. Defenders hunting with generic IOC lists from Western vendors are typically working with indicators that are 6 to 12 months behind the threat actor's current operational posture.
Actor Context
Hunting without actor context means searching for any needle in a haystack rather than the specific signatures of a known adversary. Most commercial threat feeds provide IOC lists without campaign attribution, TTP history, or targeting patterns. Without knowing which APT group is relevant to your sector and geography, hunting hypotheses are untestable and coverage is incomplete.
Hidden from Traditional IDS
APAC-origin APT groups have consistently moved to fully encrypted C2 infrastructure using commercial cloud services, HTTPS tunneling, and domain fronting to blend into legitimate enterprise traffic. Traditional IDS tools that rely on payload signatures or unencrypted protocol inspection cannot observe these channels, leaving analysts blind to active APT C2 activity on their networks.
by Western Intelligence Vendors
Western threat intelligence vendors build their APAC coverage from open sources, partner sharing, and aggregated data, not firsthand research. ThreatBook discovered and named SilverFox, an APAC-origin APT group that was entirely absent from Western TI platforms when ThreatBook first published its research. Groups like SilverFox regularly appear in ThreatBook's intelligence 6 to 12 months before non-Asian vendors begin tracking them. For organizations with APAC exposure, this gap is material operational risk, not just a data quality concern.
Actor-Led Hunting with
Network-Level Validation
ThreatBook's APT hunting approach starts with the adversary, not the alert. ATI provides deep profiles on 2,000+ adversary groups, including campaign histories, infrastructure patterns, targeting sectors, and MITRE ATT&CK technique mappings that let analysts build specific, testable hunting hypotheses before touching network data. ThreatBook has tracked APAC APT groups from their first-observed activity since 2015, providing firsthand visibility that Western TI aggregators cannot replicate.
TDP executes the network hunt: full traffic analysis including encrypted channels, compromised host detection via IOC-intelligence fusion, and zero-day detection via ML behavioral analysis. When TDP surfaces a match, ATI provides the campaign context, actor attribution, known peer organization targets, and current infrastructure patterns, so your team responds to the adversary, not just the indicator.
- 2,000+ adversary group profiles with MITRE ATT&CK mapping give analysts specific TTPs to hunt, not generic behavioral baselines
- TDP detects APT C2 in encrypted traffic using behavioral ML, no decryption, no signature dependency
- APAC-native research since 2015 means ThreatBook tracks regional APT groups months before Western vendors observe them
- Compromised host detection fuses rule-based detection with live IOC intelligence, confirming compromise, not just suspicious behavior
- ATI integrates with SIEM and firewall via API, hunting rules and new IOCs update your controls in real time
What Separates ThreatBook APT
Hunting from Generic Threat Feeds
ATI maintains continuously updated profiles on 2,000+ adversary groups, not just IOC lists, but full campaign histories with infrastructure fingerprints, targeting patterns by sector and geography, known affiliates, and MITRE ATT&CK technique coverage. Analysts start each hunt knowing what behavioral signatures belong to the specific actor threatening their organization.
TDP's ML engine identifies APT C2 communication patterns in fully encrypted traffic, analyzing connection timing, beacon regularity, payload size distributions, and protocol anomalies without requiring decryption. This closes the visibility gap that APT operators specifically exploit by routing C2 through TLS and HTTPS.
Since 2015, ThreatBook researchers have investigated and documented APAC-origin APT groups through direct technical analysis, reverse engineering malware samples, and tracking infrastructure registrations. ThreatBook discovered and named SilverFox, an APAC-origin APT group with no prior coverage in any Western intelligence platform at time of publication.
From Actor Profile to
Confirmed Compromise
APT hunting with ThreatBook follows an actor-led methodology: establish who is likely targeting your sector, build hypotheses from their known TTPs, hunt in network data, and attribute findings back to the actor for executive reporting and peer organization sharing.
ATI builds actor profiles relevant to your sector and geographic footprint. For an APAC financial services organization, this surfaces the specific APT groups with a history of targeting regional banks, their current infrastructure, and their most recent TTP updates.
Known TTPs from actor profiles are mapped against your network topology and asset inventory. This produces specific, testable hunting hypotheses, "Does this actor's known C2 beacon pattern appear on any internal host?", rather than broad anomaly searches.
TDP runs traffic analysis against ATI-derived hunting rules, checking for C2 beacon signatures, anomalous encrypted channel patterns, lateral movement indicators, and IOC matches. Results are prioritized by confidence and correlated across hosts automatically.
Confirmed findings are attributed to specific actor campaigns with full context: group profile, historical activity, known peer targets, and current IOCs. Attribution packages are pushed to SIEM and firewall controls immediately, and structured reports are generated for executive briefing.
What Security Teams Achieve with ThreatBook
ThreatBook's firsthand APT research since 2015 has documented over 20,000 incidents across APAC-origin and global threat actor campaigns, giving defenders a deep historical reference for hypothesis generation and attribution.
TDP's intelligence-enriched detection engine ensures that APT hunting results are actionable findings, not noise. Analysts can investigate every TDP alert with confidence that confirmed positives represent genuine compromise indicators.
ThreatBook discovered and named SilverFox before any Western vendor had published coverage of the group. This pattern repeats across APAC-origin APT actors: ThreatBook's firsthand research provides six to twelve months of lead time over non-Asian intelligence platforms, giving defenders the window to hunt proactively rather than investigate retrospectively.
