• Cryptography research team Fireblocks identified the flaw and notified the BitGo team in December 2022.
BitGo Patches Critical Vulnerability
BitGo has recently patched a critical vulnerability that threatened to expose the private keys of retail and institutional users. The vulnerability, which was discovered by cryptography research team Fireblocks, was related to BitGo Threshold Signature Scheme (TSS) wallets and had the potential to put users at risk. After being notified of the flaw in December 2022, BitGo suspended the vulnerable service on Dec 10th and released a patch in February 2023 requiring client-side updates by March 17th.
How Was The Vulnerability Discovered?
The Fireblocks team named this exploit as „Bitgo Zero Proof Vulnerability“, which would allow attackers to extract a private key in under a minute with only small amount of JavaScript code. They were able to prove this by using a free Bitgo account on mainnet, where they noticed a missing part of mandatory zero-knowledge proofs in Bitgo’s ECDSA TSS wallet protocol that allowed for exposure of the private key through simple attack methods.
What Are Multiparty Computation & Multisignature Technology?
Industry-standard enterprise-grade cryptocurrency asset platforms make use of either multiparty computing (MPC/TSS) or multisignature technology for security controls if one party is compromised. MPC/TSS distributes a private key between multiple parties, while multisignature technology requires multiple parties to sign off on transactions before they are completed– thereby adding another layer of security against malicious actors looking to gain access to assets stored on the platform.
What Does This Mean For Users?
For users who rely on these platforms for their digital asset storage needs, it is important that they keep up with all software updates as soon as possible in order minimize risk exposure due to vulnerabilities like this one uncovered by Fireblocks‘ researchers. By taking proactive measures such as updating software regularly, users can ensure maximum protection from malicious actors looking to exploit any weaknesses present within these platforms.
Conclusion
By patching this particular vulnerability quickly, BitGo has demonstrated its commitment towards providing secure services for its customers and safeguarding their assets from external threats or attacks. It is also clear that there is still much work left when it comes improving user security across cryptocurrency asset platforms— but through regular software maintenance and vigilance against potential exploits like this one can help reduce risks associated with digital asset storage solutions.
