48-Hour Incident Response & Enterprise Security Remediation
How Tech Stack Playbook executed a full AWS account recovery from an active cybersecurity breach, restored operations in under 24 hours, and implemented a 14-step security lockdown protocol.
Overview
Tech Stack Playbook was engaged by an elite executive advisory firm after a critical cybersecurity incident compromised their AWS account. An attacker exploited unsecured root credentials to launch a large-scale email abuse campaign and upload malware — triggering an AWS account suspension that took the entire platform offline.
Within 24 hours, full operational capability was restored. Within 48 hours, the environment was secured with a comprehensive 14-step lockdown protocol — significantly outperforming AWS's estimated 4-day recovery timeline. The methodology was later presented at AWS re:Inforce.
The Incident
The breach began with unsecured AWS root account credentials. The attacker used root-level access to send hundreds of thousands of unauthorized emails, upload malware to S3, and operate with unrestricted access across all services. AWS suspended the account, taking the firm's entire platform offline with a 4-day recovery estimate.
- AWS root account compromised — no MFA, broadly accessible credentials
- Hundreds of thousands of unauthorized emails sent from the account in a single evening
- Malware payloads uploaded to S3 storage buckets
- Full AWS account suspension — all applications, databases, and APIs offline
- 4-day AWS recovery estimate for ultra-high-net-worth clientele expecting zero downtime
- Publicly accessible client coaching transcripts containing confidential business strategies of nine- and ten-figure entrepreneurs
The 14-Step Security Lockdown Protocol
With operations restored in 24 hours, Tech Stack Playbook implemented a comprehensive security hardening protocol across every dimension of the AWS environment.
