Alex Bridge Incident Anlaysis

### Executive Summary: The report describes a May incident where the Alex project's deployer private key was compromised via phishing, resulting in ~\$6.3M in assets being moved (notably \$4.3M on BSC and ~\$2M in STX on Stack BTC); an external EOA front-ran the attacker and rescued funds on-chain while some STX were distributed to malicious wallets and centralized exchanges. CertiK documents contract upgrades, failed attacker withdrawals on EVM chains, associated malicious and white-hat addresses, and emphasizes the rising frequency and outsized impact of private key compromises.
