Transit Finance Hack Analysis
Transit Finance Hack Analysis
Overview:
On December 20, 2023, Transit Finance suffered an attack due to a lack of input validation for the pool, leading to an approximate loss of over 110K USD.
Smart Contract Hack Overview:
Decoding the Smart Contract Vulnerability:
1. The vulnerability’s root cause was the lack of proper input validation.
2. The vulnerability allowed the attacker to use a forged pool and manipulate the WBNB/BUSD pool path.
3. The attacker manipulated the first swap by controlling the actualAmountIn parameter, substituting it with a forged value.
4. This led to the SwapRouter using the manipulated actualAmountIn as the initial value for the swap in the WBNB/BUSD pool.
Mitigation and Best Practices:
- Implement strict checks for pool parameters and paths to prevent forged or malicious input
- Always validate your code by writing comprehensive test cases that cover all the possible business logic.
- To prevent such vulnerabilities, the best Smart Contract auditors must examine the Smart Contracts for logical issues. We at CredShields provide smart contract security and end-to-end security of web applications and externally exposed networks. Schedule a call at https://credshields.com/
