Blockchain security firm dWallet Labs recently disclosed a vulnerability that it claims could affect up to $1 billion worth of crypto, with assets such as Ether (ETH), Aptos (APT), BNB (BNB) and Sui (SUI) at risk.
In a paper sent to Cointelegraph, dWallet Labs reported a potential vulnerability in validators hosted by an infrastructure provider called InfStones. According to dWallet Labs, it started a research paper covering attacks on blockchain networks and collecting private keys with Web2 attacks. During this research, dWallet Labs said it discovered vulnerabilities in InfStones validators. It wrote:
According to dWallet Labs, an attacker who exploits the vulnerability can acquire the private keys of validators across different blockchain networks. “Over one billion dollars of staked assets were staked on all of these validators, and such an attacker would have been able to gain full control of all of them,” it added.

On Nov. 21, InfStones responded to Cointelegraph’s request for comment, denying that the bug could affect $1 billion in assets. Darko Radunovic, a representative from InfStones, told Cointelegraph that the potential vulnerability could only affect a small fraction of the live nodes it already launched.
According to Radunovic, the potential vulnerability was discovered in 237 instances, including 212 cases designated for testing and 25 instances as freshly launched nodes in the production environment. “The instances identified in production constitute a fraction below 0.1% of the live nodes we have launched to date,” Radunovic said in a statement. The company also published a blog post saying the vulnerability was resolved.
