On December 19th, OKX, a major cryptocurrency exchange, announced the discovery and prompt resolution of a security issue in its iOS app. The revealed details suggest that the flaw could potentially affect external service providers connected to OKX. However, the problem has been swiftly identified and rectified. OKX assures that there have been no reported instances of harm or asset loss for users.
Despite this, the exchange recommends users exercise caution and update their iOS app to the latest version (6.45.0) as a precautionary measure. CertiK, a security firm, also weighed in on the matter, confirming the detection of the issue and issuing a warning to OKX.

In recent months, hackers have been targeting cryptocurrency wallets and exchanges more frequently. In November, $114 million was stolen from Poloniex, and shortly after, there was a $100 million theft at HTX and the cross-chain bridge Heco. In June, users of the Atomic wallet experienced losses totaling $35 million in bitcoin (BTC), ether (ETH), and other tokens after updating to a new version of the iOS app.
As per DefiLlama data, OKX currently holds the position of the world’s second-largest cryptocurrency exchange, following closely behind Binance. It registers a 24-hour spot trading volume of $2.4 billion and manages customer assets amounting to $12.2 billion.
