Crypto wallet researchers have found bugs that could expose the wallet data to exchanges as we are reading more about it in the upcoming crypto news.
Security experts and wallet researchers unveiled a huge number of vulnerabilities in the open-source libraries that are used by most exchanges that could be easily exploited by hackers that are looking for a way in the users’ wallets. During the Black Hat cybersecurity conference, the experts said that some of the issues that are affecting the exchanges have not been fixed but there are others that pose threats to their owners.
Jean-Philippe Aumasson, the co-founder of Taurus Group and vice-president at Kudelski Security, said that the vulnerabilities were discovered by Omer Shlomovits who is a co-founder of the mobile wallet ZenGo into three categories. The first type of attack requires hackers to use an insider of the exchange and to exploit a vulnerability in an open-source library that is made by simply leading the exchange that the researchers chose not to name. By using the flaw in the mechanism for refreshing keys, the hackers could manipulate the process and change key components while leaving all of the components intact. The attackers can, therefore, prevent the exchange from accessing crypto.
The researcher informed the developers that the bug exists one week after the code went live. However, since it was found in an open-source library, it is possible that other exchanges could still be using the operations. The second option includes hackers exploiting flaws in the rotation process. If a failure in the validation of the statements that the exchange makes occurs, it could allow a rouge exchange to extract the keys over multiple key refreshes that will seize the control of their assets. The bug was found in an open-source library that was developed by a huge management firm whose name remains hidden.
The third category for attacks could occur when the trusted parties derive the segments of the key and then generate a random number that is publicly verified and tested. The researchers found that one protocol in an open-source library developed by Binance failed to check the random numbers. This problem could allow a rouge party in the key generation procedure and capitalize on the failure to extract the segments of the key.
