## Context
Post-exploitation, the attacker established persistence by deploying malicious smart contracts across various networks. These contracts were designed to maintain access and facilitate further unauthorized transactions.

## Analysis
The deployed contracts included backdoors and logic bombs that could be activated remotely, indicating advanced planning and technical sophistication.

## Implications
This persistence mechanism could allow the attacker to maintain control over the exploited networks indefinitely, posing ongoing risks.

## Recommendations
- Identify and isolate compromised smart contracts.
- Revoke permissions and conduct a thorough review of contract interactions.
