Report Shows Early Crypto Wallets Exposed to Billion-Dollar Vulnerability
A critical vulnerability has been discovered in early cryptocurrency wallets, posing a significant risk to billions of dollars in digital assets. Cybersecurity startup Unciphered conducted an exhaustive 22-month investigation, revealing a flaw in the BitcoinJS software used for wallet generation between 2011 and 2015. This flaw leaves wallets vulnerable to potential exploitation. As a result, millions of users are being strongly advised to transfer their assets to wallets generated with updated, secure software.
Discovery of the Vulnerability
Unciphered’s investigation unveiled a significant flaw in the widely utilized BitcoinJS, a browser-based cryptocurrency wallet generation tool. The flaw originates from the SecureRandom function in the JSBN javascript library, compounded by weaknesses in major browsers’ Math.random implementations. This vulnerability affects wallets created between 2011 and 2015, with earlier wallets being particularly vulnerable. The discovery of this vulnerability occurred during a project for a client who was locked out of a Blockchain.com bitcoin wallet. This led to the realization that BitcoinJS-generated wallets from 2011 to 2015 could also be at risk. Millions of cryptocurrency wallets generated within this timeframe potentially face exploitation, posing a substantial threat to their associated assets.
Understanding the Vulnerability
The vulnerability stems from BitcoinJS’s implementation of the SecureRandom function from the JSBN library. The function, which encounters deficiencies in its entropy collection and pseudo-random number generation (PRNG), creates a scenario in which attackers can potentially recover key material. Furthermore, the SecureRandom function’s reliance on weaker RNG methods instead of implementing more secure browser cryptographic functions exacerbates the issue. This vulnerability is critical as it was discovered that bitcoin private keys, which require 256 bits of entropy, were generated with less entropy than necessary. The significance of the vulnerability varies among wallets, with some being more susceptible to attacks than others. Over time, mitigation measures have been implemented, incorporating additional entropy sources to reduce the risk for newer wallets.
Implications for Bitcoin and Other Cryptocurrencies
While the vulnerability initially affects Bitcoin, it has the potential to impact other cryptocurrencies such as dogecoin, litecoin, and zcash-based wallets. Additionally, various wallet services and projects that derive their code from BitcoinJS, including reputable ones like Dogechain.info and Blockchain.info, may also be affected. This highlights the wide-ranging implications of the vulnerability across multiple cryptocurrencies. The discovery of this vulnerability sheds light on the inherent risks involved in software development, particularly when relying on third-party library dependencies. Similar vulnerabilities have been observed in other projects, such as OpenSSL on Debian platforms. It emphasizes the constant need for vigilance and improved security measures when dealing with financial assets and sensitive information.
Immediate Action Required to Secure Assets
Given the severity of the vulnerability, immediate action is crucial to safeguard digital assets. Users with affected wallets are strongly urged to transfer their assets to newly generated wallets that utilize reliable, updated software. This proactive step serves as a preventive measure against potential exploitation and ensures the security of one’s cryptocurrency holdings. By utilizing secure, up-to-date software, users can reduce their exposure to vulnerabilities and protect their valuable assets.
Coordination to Alert Users
Unciphered has collaboratively worked with various entities to raise awareness among millions of users regarding this vulnerability. The cooperation between Unciphered and other stakeholders ensures that individuals with assets at risk are promptly notified and encouraged to take immediate action. By coordinating efforts and disseminating information, more users can be effectively reached, increasing the overall security of the cryptocurrency community.
Mitigation Measures and Reduced Risk
Market stakeholders have taken measures to mitigate the vulnerability and decrease the risk associated with affected wallets. Implementing additional entropy sources is one such measure that has been undertaken. By incorporating more sources of randomness during the wallet generation process, the potential for exploitation is minimized. Although this provides reduced risk for newer wallets, older wallets created between 2011 and 2015 remain particularly vulnerable. Continuous efforts are being made to improve the security of all cryptocurrency wallets and ensure the protection of users’ assets.

Widespread Implications for Multiple Cryptocurrencies
The implications of this vulnerability are not confined to bitcoin wallets alone. Other cryptocurrencies, including dogecoin, litecoin, and zcash-based assets, are also at risk. The widespread impact extends to numerous wallet services and projects that rely on BitcoinJS’s codebase. The potential vulnerability of wallet services, even those that are widely used, underscores the need for heightened security measures and assessments across the cryptocurrency landscape.
