 Threat Hunting Queries

Forged By Attackers, Built For Defenders

Threat Hunting Forged by Attackers

We use 10+ years of advanced attack simulation to build high-fidelity queries that catch what standard EDRs miss. Tailored to your business sector, mapped to your specific APTs.

Know Your Enemy

We analyze your specific business sector to identify the APTs and ransomware groups targeting you. We map their TTPs (Tactics, Techniques, and Procedures) before writing a single line of code.

Built by Attackers

With 10+ years of advanced Red Team experience, we know exactly how attackers bypass standard alerts. We engineer detections to catch the subtle behaviors and anomalies that default vendor rules miss.

Your Stack, Our Rules

We are not SIEM/EDR dependent. Whether you use Splunk, Sentinel, Elastic, CrowdStrike or MDE, we translate our advanced detection logic into the specific language of your existing environment.

Standard Generic Detection

ProcessName == "powershell.exe"
AND CommandLine CONTAINS "-enc"
HIGH FALSE
POSITIVES
Easily Evaded

Valhguard Behavioral Detection

EventID: 1 (Process Create)
ParentImage: "winword.exe"
Image: "cmd.exe" OR "powershell.exe"
IntegrityLevel: "Medium"
BEHAVIOR
BASED
Red Team Validated

Full Spectrum Kill Chain Coverage

We don’t just look for malware. We hunt for malicious behavior across every stage of the attack lifecycle, from initial access to data exfiltration.

Identity Defense

Stop attackers from stealing the keys to the kingdom. We detect sophisticated credential dumping attempts including LSASS access, DCSync attacks, and token manipulation before they escalate.

Evasion Hunting

Catch the stealthy techniques used to blind your security tools. Our queries spot EDR unhooking, process injection, parent PID spoofing, and impairment of auditing logs.

C2 Communication

Identify the heartbeat of the adversary. We analyze network jitter and beaconing patterns to detect Cobalt Strike, Sliver, and other C2 frameworks hiding in your SSL/TLS traffic.

Data Protection

Detect the final stage before the breach becomes a headline. We hunt for large data staging, use of tools like Rclone or Mega, and anomalous cloud API calls indicating data theft.

Engagement Models
