OKX shores up App security following bug discovery
Cryptocurrency exchange OKX has swiftly responded to a recently uncovered security flaw by releasing an updated version (v6.45.0) of its iOS app.
User data and asset vulnerability
The flaw was identified by Web3 and blockchain security specialist CertiK. It posed a Remote Code Execution (RCE) vulnerability that had the potential to compromise sensitive user data and crypto assets. Notwithstanding that, no user assets were lost or security compromised.
Taking to the X social media platform on Tuesday, CertiK wrote:
”Attention! We urge users of OKX wallets to update their iOS app to the latest version immediately. Earlier this month, we identified and reported a critical Remote Code Execution (RCE) vulnerability in the OKX iOS App, leading to potential compromise of sensitive data and crypto assets.”

Prompt response
Recognizing the risk, OKX has acted promptly to rectify the issue and commit to protecting user assets. It too followed up on social media with its own announcement:
”Thanks @Certik for the note. We’ve completed the relevant upgrade & this is no longer an issue. We have verified that this did not impact any customer assets. The fix has been deployed to iOS version 6.45.0 & we recommend you update the app asap.”
Ongoing exploits
This security incident has played out amid a backdrop that has seen a worrying number of hacks, exploits and vulnerabilities in the crypto space. In recent weeks, hacks at HTX (formerly Huobi), cross-chain bridge Heco and Poloniex have accounted for millions of dollars in losses.
As recently as last week, users of the Ledger hardware wallet were told by the company not to connect to decentralized applications as it had discovered that a malicious version of its Ledger Connect software had been distributed.
Industry collaboration
The collaboration between OKX and CertiK in addressing this security concern is demonstrative of how industry actors are having to cooperate in order to deal effectively with these vulnerabilities and threats.
Transparent communication and a swift response in this instance are likely to have played a role in minimizing any potential loss. In a noteworthy development, OKX, in collaboration with Tether, has collaborated with the United States Department of Justice (DOJ) to freeze $225 million in USDT tokens.
This unprecedented action primarily targeted a human trafficking syndicate in Southeast Asia, illustrating the increasing cooperation between crypto entities and law enforcement in addressing illegal activities involving digital currencies.
The immediate resolution of the iOS app vulnerability in this instance resulted in no loss occurring. That outcome underscores the importance of the prioritization of user safety and data security.
With the updated app version (v6.45.0) now available, users can proceed with their crypto transactions with renewed confidence in the platform’s security measures. As the cryptocurrency landscape evolves, crypto platforms and platform users will need to remain vigilant in order to safeguard and protect funds.
