The security issues of prediction markets are beginning to surface. The malicious code incident involving the Polymarket copycat bot on GitHub is worth noting—developers embedded private key theft logic into the code, so once users run the program, the wallet private key in the .env file will be automatically read. Even more concerning is that the author repeatedly modified commits to hide malicious packages, indicating this is not a simple mistake but a deliberate act.

From an on-chain perspective, the chain reaction of such incidents may include: rapid outflow of funds from affected addresses, abnormal fluctuations in related trading pairs, and subsequent address tagging and clustering. It is recommended to monitor recent whale activities related to Polymarket, especially sudden large withdrawals and cross-chain bridging actions—these often signal the escape of stolen funds.

For users participating in prediction markets, the key advice is: use non-official tools with caution, especially those requiring private key authorization or deployed locally. Even with open-source code, carefully review each commit. Fund security should always take precedence over potential gains.
