Adversary Simulation
Offensive Research

ValyrSec operates as a high-tier adversary, utilizing proprietary tradecraft developed in our research labs. Our mission is to challenge the resilience of enterprise security stacks by simulating stealthy, persistent, and multi-stage attacks that mirror real-world APT behavior.

Operational Parameters

  • Stealth Mode OPSEC Level 4
  • Evasion Focus Indirect Syscalls
  • MFA Bypass Session Hijacking
  • Infrastructure Private C2

Adversary Intelligence

T1558.003 // Kerberoasting

Active Directory Dominance

Modern AD attacks focus on stealthy delegation abuses and ACL manipulation. We track the latest tradecraft from SpecterOps and Harmj0y to simulate advanced escalation paths.

T1528 // Token Theft

Identity & MFA Bypass

As organizations move to "Passwordless", attackers shift to Adversary-in-the-Middle (AiTM) and session hijacking. We utilize research from Microsoft Threat Intelligence to test resilience.

EDR Evasion & Memory Safety

Modern EDR solutions rely heavily on user-mode API hooking. ValyrSec utilizes **Indirect Syscalls** and **Dynamic Invocations** to execute instructions directly through the Windows Kernel, rendering user-land hooks blind.
