In addition, I think Vultisig's innovative wallet approach (integrated into other wallets now) would have potentially saved ByBit from the hack. From GPT: "The recent $1.5 billion hack of Bybit involved attackers manipulating a routine transfer from the exchangeâs cold wallet to a warm wallet. They altered the smart contract logic and masked the signing interface, enabling unauthorized control over the cold wallet and subsequent transfer of 401,000 Ethereum to an unknown address. ïżŒ
Vultisig is a self-custodial, multi-chain crypto wallet utilizing threshold signature schemes (TSS). This approach requires multiple devices to approve a transaction, eliminating a single point of failure. Each device holds a unique âvault share,â and a private key is never fully assembled, enhancing security. ïżŒ
In the case of Bybit, the hack exploited vulnerabilities in the transaction approval process, allowing attackers to manipulate smart contract logic and gain unauthorized access. Implementing a TSS-based system like Vultisig could have added an extra layer of security by requiring multiple independent approvals from separate devices. This multi-factor authentication makes it significantly more challenging for an attacker to compromise all necessary devices simultaneously, potentially preventing unauthorized transactions.
However, itâs important to note that while TSS enhances security, it doesnât guarantee absolute protection. The effectiveness of such a system depends on the secure management of all participating devices and the integrity of the software used. Comprehensive security measures, including regular audits, user education, and robust operational protocols, are essential to safeguard against sophisticated attacks."
