According to the firm, while working to retrieve a Bitcoin (BTC) wallet for a customer, they discovered a potential issue for wallets generated by BitcoinJS and derivative projects. The issue could possibly affect millions of wallets and around $2.1 billion in crypto assets, according to the cybersecurity company.
The firm also believes that multiple blockchains and projects could be affected. Apart from BTC, the company highlighted that Dogecoin (DOGE), Litecoin (LTC) and Zcash (ZEC) wallets could also potentially contain the vulnerability.

In addition, the company said that millions have already received an alert about the problem. For those who are using crypto wallets generated within the 2011 to 2015 time frame, the company recommends transferring their assets to wallets that were generated more recently. They wrote:
“If you are an individual who has generated a self-custody wallet using a web browser before 2016, you should consider moving your funds to a more recently created wallet generated by trusted software.”
While the company said that not all impacted wallets are affected equally, it also confirmed that the vulnerability is exploitable. However, the company did not provide any details about the exploitation of the vulnerability to avoid providing more information to bad actors in the space.
