# Best Practices: Mitigating Geopolitical Wiper Attacks
## Overview
These practices address the rise of "wiper" campaigns—destructive cyberattacks driven by geopolitical tensions. Unlike ransomware, these attacks aim for maximum operational disruption and system destruction. The focus shifts from perimeter defense to **containment and resilience**, specifically targeting an attacker's ability to move laterally using legitimate administrative tools.
## Key Recommendations
### Immediate Actions
1. **Enforce Multi-Factor Authentication (MFA) Internally:** Move beyond MFA for just VPN access. Require MFA for all internal administrative services and lateral logins.
2. **Audit VPN Credentials:** Reset credentials for high-privileged accounts and decommission any inactive or "gray" tunnels.
3. **Disable Unnecessary Admin Protocols:** Identify and disable unused RDP, PowerShell Remoting, WMI, and SMB ports on workstations that do not require them.
4. **Identify Covert Tunneling Tools:** Scan environment for unauthorized installations of NetBird or similar tunneling software used for persistence.
### Short-term Improvements (1-3 months)
1. **Transition to Identity-Aware Access:** Replace flat network connectivity with identity-based controls that verify who is accessing specific systems regardless of network location.
2. **Implement Automated Containment:** Deploy tools that can automatically isolate compromised hosts or segments based on detected anomalous "hands-on" activity.
3. **Privilege Management:** Revoke local administrative rights for standard users to prevent attackers from escalating privileges once inside.
### Long-term Strategy (3+ months)
1. **Zero Trust Architecture (ZTA):** Build a "self-defending network" where no user or device is trusted by default, and every access request is strictly verified.
2. **Micro-segmentation:** Deeply segment the network to ensure that a breach in one department (e.g., order processing) cannot spread to manufacturing or logistics.
3. **Resilience Drills:** Shift from "Prevention" tabletop exercises to "Survival" exercises, focusing on how to operate manually if 50%+ of the machine fleet is wiped.
## Implementation Guidance
### For Small Organizations
* **Focus on MFA:** Prioritize MFA on every possible service, especially email and remote access.
* **Default Deny:** Use built-in Windows Firewalls to block inbound RDP and SMB on all non-server endpoints.
### For Medium Organizations
* **Identity Consolidation:** Ensure all administrative actions are tied to a central Identity Provider (IdP) to enable rapid account revocation.
* **Standardize Admin Tools:** Limit administrative work to specific "Jump Boxes" to make any admin traffic from other sources immediately suspicious.
### For Large Enterprises
* **Automated Lateral Movement Protection:** Implement specialized security layering (like Zero Networks) that automates the closing and opening of ports based on real-time identity verification.
* **Global Supply Chain Segregation:** Isolate regional networks so that a wiper attack in one country (e.g., a branch office) cannot traverse the backbone to global headquarters.
## Configuration Examples
While specific code depends on the vendor, the article emphasizes controlling these protocols:
* **Port 3389 (RDP):** Block at the network level; allow only via authenticated VPN/Jump Box.
* **Port 445 (SMB):** Disable "File and Printer Sharing" on all public or unprotected network profiles.
* **PowerShell Remoting (WinRM):** Restrict to a specific group of administrative IP addresses via Group Policy (GPO).
## Compliance Alignment
* **NIST SP 800-207:** Implementation of Zero Trust Architecture principles.
* **CIS Controls v8:** Specifically Control 3 (Data Protection) and Control 4 (Secure Configuration).
* **ISO/IEC 27001:** Alignment with A.12 (Operations Security) and A.13 (Communications Security).
## Common Pitfalls to Avoid
* **Over-reliance on EDR:** Wiper attackers often use "living-off-the-land" (LotL) techniques with legitimate tools (PowerShell, WMI) that traditional EDR may not flag as malware.
* **The "MFA Fatigue" Gap:** Granting broad network access after a single VPN MFA prompt.
* **Ignoring Persistence:** Failing to look for tunneling tools (like NetBird) that allow attackers to bypass the VPN entirely for subsequent entries.
