# Building Malware Incident Communication Template

## Overview

Effective communication during malware incidents is critical for coordinated response, stakeholder management, and regulatory compliance. A structured communication framework ensures the right people receive appropriate information at the right time, preventing panic while maintaining transparency. Communication templates should cover internal escalation, executive briefings, technical advisories for IT teams, customer notifications, regulatory disclosures, and media statements. The framework must account for different malware types (ransomware, wiper, trojan, worm) and severity levels that drive escalation speed and audience.


## When to Use

- When deploying or configuring building malware incident communication template capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation

## Prerequisites

- Familiarity with incident response concepts and tools
- Access to a test or lab environment for safe execution
- Python 3.8+ with required dependencies installed
- Appropriate authorization for any testing activities

## Communication Framework

### Severity Classification

| Severity | Description | Notification Timeline | Audience |
|----------|-------------|----------------------|----------|
| P1 - Critical | Ransomware, wiper, or widespread infection affecting business operations | Within 15 minutes | CISO, CEO, Legal, Board (if applicable) |
| P2 - High | Targeted malware on critical systems, data exfiltration suspected | Within 1 hour | CISO, IT Director, Legal |
| P3 - Medium | Contained malware infection, limited spread | Within 4 hours | Security Manager, IT Director |
| P4 - Low | Single endpoint infection, quickly contained | Within 24 hours | Security Team Lead |

### Communication Channels

| Channel | Use Case | Security Level |
|---------|----------|---------------|
| Out-of-band phone calls | Initial critical notifications | Highest |
| Encrypted messaging (Signal) | Real-time IR team coordination | High |
| Secure email (encrypted) | Formal notifications, documentation | High |
| War room (physical/virtual) | Ongoing incident coordination | Medium |
| Incident ticketing system | Status tracking and documentation | Medium |
| Company intranet | Broad employee communication | Standard |
