When an enterprise, exchange, or Web3 protocol suffers a security compromise, panic is the default emotion. Millions of dollars can drain from smart contracts or hot wallets in minutes.
In the immediate chaos following a breach, security teams naturally scramble to patch vulnerabilities, revoke keys, and restore systems. However, well-intentioned IT teams frequently make a critical error: in their rush to remediate, they overwrite or destroy the very digital evidence needed to track the attacker and recover the assets.
What your team does during the first six hours of an incident determines whether you will be able to perform root-cause analysis, fulfill regulatory breach notifications, and coordinate with law enforcement.
The First 6 Hours: Emergency Incident Response Checklist
To preserve critical forensic data while containing the threat, follow this tactical triage workflow:
1. Contain Without Destroying Evidence
- Do NOT Power Down or Reboot Servers: Volatile RAM memory contains active process trees, network connection states, and unencrypted keys. Rebooting wipes this data permanently. Isolate affected instances at the network/firewall level instead.
- Revoke Compromised Credentials Immediately: Rotate API keys, admin tokens, database passwords, and multisig signer permissions from a known clean device.
2. Capture Volatile Digital Artifacts
- Preserve System Logs: Export and lock system logs (e.g., AWS CloudTrail, NGINX access logs, Linux auth logs, and API gateway records). Store cryptographic hashes of these log files immediately to prove they haven’t been altered.
- Capture Network PCAPs: Save raw packet captures surrounding the exploit timestamp to analyse payload structures and command-and-control (C2) server communications.
3. Initiate On-Chain Asset Isolation
- Identify Transaction Hashes (TxIDs): Isolate the exact attacker wallet addresses and transaction hashes across all impacted chains.
- Engage Emergency Exchange Communications: Notify compliance teams at major centralised exchanges to flag and freeze attacker deposit addresses as funds move through bridges or mixing protocols.

How MAC Chain Assists During Security Incidents
MAC Chain provides 24/7 rapid response support for enterprises, platforms, and exchanges facing security breaches or fraud. With offices servicing Sydney, Melbourne, and Adelaide, our accredited team combines deep Web3 smart contract expertise with computer forensics to contain threats and trace stolen assets.
Our Incident Response Workflow
- Immediate Rapid Response (24/7): You can reach our urgent response team (+61 8 8215 0020 / urgent@macchain.au) to stabilise the situation without destroying critical RAM or server artifacts.
- Root Cause Analysis: We analyse system logs, server images, and smart contracts to identify the precise compromise vector (e.g., compromised private key vs. logic vulnerability).
- On-Chain Tracking & Exchange Liaison: We trace movement across 58+ blockchain networks, regularly collaborating with law enforcement agencies and major exchange compliance teams worldwide to flag illicit flows.
- Regulatory Reporting Packages: We prepare comprehensive documentation aligned with regulatory frameworks like the Office of the Australian Information Commissioner (OAIC) Notifiable Data Breaches scheme, giving insurers and law enforcement what they need to move forward.
When every minute counts, having an experienced team on standby turns chaotic panic into structured, effective containment.
