Hacker Exploited 55 Days of Failed Transactions to Drain $3 Million From GalaChain Wallets

WHY IT MATTERS

This incident illustrates a less obvious type of blockchain attack. Most people think of hacks as brute-force break-ins, but in this case the attacker reportedly learned how the system worked by deliberately sending transactions that would fail — similar to a burglar testing every door and window in a building over weeks to find one that is unlocked. Each failed attempt gave the attacker a small piece of information about how the security system responded, and eventually those pieces added up to enough knowledge to break in. For newcomers to crypto, this is a reminder that blockchains are software systems, and like all software, they can contain bugs or design flaws that skilled attackers may discover over time. Users who hold assets on any blockchain platform should understand that security is never guaranteed, and the safety of their funds depends on the quality of the underlying code and the responsiveness of the development team.
