Stop Ransomware at DNS,
Network, and Perimeter
ThreatBook runs a three-layer defense against ransomware operators: ATI tracks 1,000+ cybercrime groups and delivers current IOCs to your controls, TDP detects C2 callbacks and lateral movement in encrypted traffic, and OneDNS intercepts ransomware DNS resolution before the payload executes, with a closed loop of detection, interception, and evidence collection at each layer.
Why Standard Controls Fail Against
Modern Ransomware Operators
Ransomware groups have professionalized their operations. They use encrypted C2 channels, living-off-the-land lateral movement, and DNS-based staging that bypasses signature-based perimeter controls. Defenders fighting with low-quality IOC feeds and legacy network monitors are consistently behind the threat.
Create False Positive Avalanches
Generic threat feeds aggregate data from public sources with no actor context and minimal validation. The result is alert queues flooded with false positives, analysts spend hours chasing noise while actual ransomware staging goes unnoticed. When every IP looks suspicious, none of them get the attention they deserve.
Blind to Signature Detection
Ransomware operators consistently route C2 traffic over TLS and HTTPS, making it invisible to traditional signature-based IDS and deep packet inspection tools that require decryption. By the time lateral movement is observed through other signals, the threat actor has typically had days of dwell time on the network.
Bypass Network Controls
DNS is both a staging mechanism and a persistence channel for ransomware payloads. Most enterprise networks have no DNS-layer visibility, so ransomware DNS resolution, contacting C2 infrastructure, downloading staged components, or exfiltrating data via DNS tunneling, proceeds undetected through firewalls and proxies that inspect only higher-layer traffic.
Three Layers That Close
Every Ransomware Entry Point
ThreatBook's ransomware defense is a coordinated three-layer architecture. ATI provides validated IOC intelligence derived from tracking 1,000+ cybercrime groups, not aggregated from public feeds, and pushes those indicators directly to your firewall, SIEM, and OneDNS in real time. TDP monitors all network traffic including encrypted channels using behavioral ML, detecting C2 communication patterns without requiring decryption. OneDNS resolves every DNS query against ATI intelligence, intercepting ransomware staging before the payload ever reaches a host.
The three layers share context: when OneDNS intercepts a DNS query, TDP correlates the initiating host, and ATI provides the actor group attribution. Your analysts receive a complete picture, not three separate alerts from three separate tools.
- ATI tracks 1,000+ cybercrime groups including ransomware operators with MITRE ATT&CK mapping, IOCs carry actor context, not just indicators
- TDP detects C2 callbacks and lateral movement in fully encrypted traffic using ML behavioral analysis, no decryption required
- OneDNS intercepts ransomware DNS resolution before payload download, with 99.9% detecting rate backed by live ATI intelligence
- Closed detection loop: every interception event generates evidence, DNS logs, network flows, host associations, for incident response
- API integration pushes ATI IOCs to firewalls and SIEM automatically, keeping perimeter controls current without manual updates
The Capabilities That Make the
Three-Layer Defense Work
ATI maintains continuous profiles on 1,000+ cybercrime groups including ransomware-as-a-service operators, tracking infrastructure changes, affiliate TTPs, and new IOCs as campaigns evolve. Each indicator is validated against 99.9% accuracy standards before distribution, defenders get IOCs that work, not IOCs that flood alert queues.
TDP's ML engine analyzes traffic flow characteristics, connection timing, beacon patterns, and protocol anomalies to identify C2 communication in encrypted channels without decrypting them. This catches ransomware operators who have specifically engineered their infrastructure to blend into normal HTTPS traffic patterns.
OneDNS resolves every enterprise DNS query against live ATI ransomware intelligence, blocking resolution to known C2 domains, staging infrastructure, and exfiltration channels. The 99.9% detecting rate is maintained against active ransomware infrastructure, and every blocked query is logged with full evidence for forensic use.
From Deployment to
Actor Attribution in Hours
The three-layer defense is designed to be operational within a single day. Each layer integrates with your existing infrastructure via API and starts generating intelligence-enriched detections immediately, with no extended tuning period required.
TDP is deployed on your network spans. OneDNS is configured as your enterprise DNS resolver. ATI connects to your SIEM and firewall via API, pushing the initial ransomware IOC set for your industry and region within minutes of activation.
OneDNS intercepts every ransomware-related DNS query, staging domains, C2 infrastructure, exfiltration channels, before resolution completes. Each blocked query triggers an alert with the associated ATI threat actor profile.
TDP's ML engine identifies C2 callbacks, lateral movement patterns, and data staging in network traffic, including fully encrypted flows. When behavior matches ransomware operator TTPs, TDP correlates the activity across affected hosts and generates a prioritized alert.
ATI provides full actor attribution, which ransomware group, their typical dwell time, common persistence mechanisms, and known exfiltration paths. Updated IOCs are pushed immediately to your firewall and SIEM so containment begins before manual response completes.
What Security Teams Achieve with ThreatBook
OneDNS's multi-dimensional reputation engine eliminates the majority of false-positive DNS alerts before they reach the analyst queue, so security teams respond to genuine ransomware indicators rather than noise.
ATI's daily IOC refresh covers 80M+ validated malicious IPs including ransomware staging and C2 infrastructure, keeping perimeter controls current against operators who rotate infrastructure frequently.
ATI's validation process maintains 99.9% accuracy across all distributed IOCs, meaning defenders can act on every indicator without dedicating analyst time to secondary validation before blocking.
