According to a blog post published by developers of crypto wallet ZenGo, the firm said it had uncovered security vulnerabilities in transaction simulation solutions used by popular decentralized applications, or dApps. Dubbed the "red pill attack," this vulnerability allowed malicious dApps to steal user assets based on opaque transaction approvals offered to and approved by users. The vulnerability derives its name from the iconic "red pill" scene from The Matrix movie series.
ZenGo claimed its research revealed that many leading vendors, including Coinbase (NASDAQ:COIN) Wallet, were at one point in time vulnerable to such attacks. "All vendors were very receptive to our reports," said ZenGo, "and most of them were quick to fix their faulty implementations."
