The Milk Sad Vulnerability: A Dangerous Flaw in Bitcoin Wallets
In late July, information security firm Distrust uncovered a major vulnerability in Bitcoin wallets called “Milk Sad.” This flaw allowed hackers to steal roughly $900,000 from unsuspecting users. Here are the key points of this concerning issue:
- Libbitcoin, an alternative to Bitcoin Core, was once considered secure but has now been revealed as unsafe.
- Hackers discovered an obscure vulnerability in wallets generated by the Libbitcoin explorer, BX, and began stealing funds.
- The most significant theft was 29.65 BTC, worth about $870,000.
- Other cryptocurrencies, including Ethereum, Zcash, Solana, and Dogecoin, were also affected by the Milk Sad vulnerability.
- The flaw was due to the insufficient randomness of seed phrases generated by the BX software, making them vulnerable to brute-force attacks.
Despite claims by BX’s lead developer that it was the result of misusing the software, cryptographers in the Bitcoin community argue that it is indeed a bug that needs to be addressed.
Hot Take: A Wake-Up Call for Crypto Security
The Milk Sad vulnerability serves as a reminder of the constant threats faced in the world of cryptocurrency. It highlights the importance of rigorous security practices and the need for developers to prioritize user protection.
