# Best Practices: Defensive Tradecraft & Ransomware Mitigation
## Overview
These practices address the shift from reactive security to an "attacker mindset." By understanding how threat actors exploit macros, navigate the dark web, and utilize specific MITRE ATT&CK tactics, organizations can better anticipate breaches rather than just reacting to them.
## Key Recommendations
### Immediate Actions
1. **Disable Macros by Default:** Configure group policies to block macros in Office files originating from the internet. This remains a primary delivery vector for malware.
2. **Conduct Tabletop Exercises:** Use the MITRE ATT&CK framework to run a "Game of Clue" style simulation. Test if your team can identify the actor, target, and success level of a hypothetical breach.
3. **Audit Public-Facing Email Security:** Ensure users are trained to look beyond just "HTTPS" or hovering over links, as macro-enabled documents are often delivered via trusted services.
### Short-term Improvements (1-3 months)
1. **Implement Internal Phishing Simulations:** Set up internal campaigns specifically using macro-based document lures to identify high-risk user groups.
2. **Dark Web Presence Audit:** Search for company credentials or data leaks on dark web marketplaces. Treat any found data not just as a privacy loss, but as a precursor to a potential ransomware event.
3. **Formalize Incident Response (IR) Playbooks:** Map your IR steps to the MITRE ATT&CK rooms (Initial Access, Persistence, Exfiltration) to ensure no stage of the attack is overlooked during an investigation.
### Long-term Strategy (3+ months)
1. **Transition to "Resilience" over "Prevention":** Shift budget and focus toward minimizing downtime. If a client believes their data isn't "worth" stealing, pivot the strategy to the value of **business continuity/time.**
2. **Continuous Tradecraft Training:** Regularly participate in technical "hack_it" style training to stay current on evolving hacker services and messaging found in ransomware gang portals.
## Implementation Guidance
### For Small Organizations
- **Focus on Time:** Since small businesses often think they aren't targets, prioritize backups and recovery speed. Your biggest vulnerability is the inability to operate during an incident.
### For Medium Organizations
- **Standardize Frameworks:** Use the MITRE ATT&CK framework to categorize the alerts you receive from your EDR/MDR tools to identify patterns in how you are being targeted.
### For Large Enterprises
- **Dark Web Monitoring:** Incorporate dark web intelligence into your SOC operations to proactively identify when your specific brand or industry is being discussed in criminal forums.
## Configuration Examples
While the article focuses on high-level takeaways, the following configuration is implied for macro-protection:
- **GPO Path:** `User Configuration > Administrative Templates > Microsoft Office 2016 > Security Settings`
- **Setting:** Enable "Block macros from running in Office files from the Internet."
## Compliance Alignment
- **NIST CSF:** Aligns with the *Protect* (Data Security) and *Respond* (Analysis) functions.
- **CIS Controls:** Specifically Control 14 (Security Awareness and Skills Training) and Control 9 (Email and Web Browser Protections).
- **MITRE ATT&CK:** Used as the primary structural framework for investigating tradecraft.
## Common Pitfalls to Avoid
- **The "No Value" Fallacy:** Assuming that because your data isn't sensitive (PII/PHI), hackers won't target you. Hackers weaponize your **downtime**, not just your data.
- **Over-reliance on Link Hovering:** Assuming that if a link looks safe, the document attached to it is also safe. Macro-based attacks bypass basic link-checking intuition.
- **Fragmented Investigations:** Failing to track an attacker's lateral movement across different stages of the MITRE framework.
