AttackIQ Releases BlackByte Ransomware Emulation to Test Security Controls

Summary
AttackIQ released an emulation of reported BlackByte behaviors for testing security controls, including scheduled-task execution, security-tool tampering, ARP discovery, shadow-copy deletion, and AES/RSA file encryption.
Key points
- AttackIQ's emulation is designed to help organizations assess detection and prevention controls against behaviors associated with BlackByte ransomware.
- Scenarios include scheduled-task execution, Windows Defender and firewall changes, and registry modifications.
- The emulation tests ARP-table discovery, Volume Shadow Copy deletion, and file encryption using AES-128-CBC and RSA-1024.
- AttackIQ says the emulation is based on behaviors reported by Cisco Talos, Trend Micro, Zscaler, Palo Alto Networks, and IC3.
- AttackIQ recommends adding a scenario for discovering Active Directory computers with PowerShell; this is presented as a proposed extension.
Article Details
- Event Type
- AttackIQ released an emulation of BlackByte ransomware behaviors for security-control validation.
- Impact
- The emulation lets organizations test detection and prevention controls against behaviors including scheduled-task execution, security-tool and firewall tampering, ARP discovery, shadow-copy deletion, and file encryption.
