#预测市场 Security issues in prediction markets are beginning to surface. The malicious code incident involving Polymarket copy-trading bots on GitHub deserves attention — developers embedded private key theft logic in the code, and once users run the program, wallet private keys in the .env file are automatically read. What's even more alarming is that the author repeatedly modified commits to hide the malicious package, indicating this was not a careless mistake but premeditated.

From an on-chain perspective, the chain reactions from such incidents may include: rapid fund outflows from affected addresses, abnormal volatility in related trading pairs, and subsequent address label clustering. It's recommended to monitor recent whale activity related to Polymarket, especially sudden large withdrawals and cross-chain bridge transactions — these are often escape signals of stolen funds.

For users participating in prediction markets, the core recommendations are: be cautious with unofficial tools, particularly copy-trading programs that require private key authorization or local deployment. Even with open-source code, carefully review every commit history. Fund security always comes before returns.
