OKX Probes Multimillion Theft After SIM Swap Attacks
A significant security breach is under investigation by the cryptocurrency exchange OKX and their security ally, SlowMist, following a multi-million-dollar theft involving two user accounts. These accounts were compromised on June 9 through an SMS attack, commonly referred to as a SIM swap. Yu Xian, founder of SlowMist, disclosed the incident, noting that the attackers created a new API Key with permissions for withdrawal and trading after obtaining risky SMS notifications from Hong Kong.
Though the exact amount stolen remains uncertain, Xian mentioned that the losses amounted to millions of dollars. While investigating the details behind the incident, SlowMist emphasized that the breach did not primarily result from failing two-factor authentication (2FA) mechanisms. Xian hinted at the possibility that there might be another point of vulnerability: “I haven’t turned on a 2FA authenticator like Google Authenticator, but I’m not sure if this is the key point,” he noted in a social media post on June 9.
Further probing by the Web3 security collective, Dilation Effect, revealed that the 2FA system employed by OKX enabled perpetrators to opt for a less secure verification method. This loophole allowed them to whitelist withdrawal addresses via SMS confirmation. Over the years, cybercriminals have devised advanced strategies to circumvent 2FA, highlighting vulnerabilities in methods previously deemed secure.
A recent example underscores this point: a Chinese trader lost $1 million earlier in June to a fraudulent scheme involving a deceptive Google Chrome plugin named Aggr. This plugin pilfered user cookies enabling hackers to surpass both password protections and 2FA verification. Such incidents underscore the escalating threat and sophistication of cyber-attacks in the crypto space.
The rise in phishing attacks complements this uptick in cyber threats. CoinGecko reported a breach involving its third-party email management service, GetResponse, resulting in 23,723 phishing emails being sent to users. These phishing efforts often aim to steal sensitive information such as the private keys to crypto wallets. Underhanded tactics like address poisoning scams trick users into sending funds to a deceitful address resembling one they previously interacted with.
Data breaches and leaks remain a significant concern in the crypto realm, facilitating many of these attacks. Private keys and personal data leaks have led to more than half of crypto-related hacks. According to Merkle Science’s 2024 HackHub report, over 55% of digital assets lost this year can be traced back to leaks focusing on private keys.
The crypto industry’s susceptibility to such risks has driven many exchanges and security platforms to hunt for more robust security measures. while taking an insightful and in-depth approach towards detecting vulnerabilities and implementing strategies to mitigate these threats, the overarching goal remains user safety and asset protection.
As these entities delve deeper into their investigations, the larger community continues to await more insights, hoping for robust solutions and heightened security protocols. This raises the importance of ongoing vigilance, both on an individual level and within the broader system, to stay ahead of evolving cyber threats in the cryptocurrency landscape.

Fascinating read! Safeguarding against cyber threats is more critical than ever. 🌐🛡️
We’re fortunate to have diligent entities like SlowMist and OKX protecting our assets. 🙏🔒
I admire the diligence and thoroughness SlowMist and OKX are showing. Keep it up!
Wow, it’s reassuring to see that OKX and SlowMist are already on top of this breach! 🕵️♂️🔍
Lets focus on enhancing our security measures together. Well done, OKX and SlowMist!
It’s 2023, and we’re still dealing with SIM swap attacks and insecure 2FA implementations. Do better, crypto companies .
Finally, some transparency and in-depth analysis on these breaches. We need more of this!
Kudos to SlowMist for their swift action and transparent updates! Together, we’ll beat these cyber threats.
Why should we trust OKX if they cant protect user funds from such basic attacks? This is a huge red flag .
It’s chilling to hear about these sophisticated scams, but knowledge is power. Thanks for the insights, OKX and SlowMist!
It’s beyond frustrating that despite all the security measures, these breaches still happen. Seriously, what’s the point of 2FA if it’s so easily circumvented? 😡
Cybersecurity is crucial, especially in the crypto world. Keep these updates coming!
Always mind-blowing how sophisticated these cyber-attacks have become. Keep it up, SlowMist!
It’s disheartening to see these security lapses. OKX and other exchanges need to rethink their strategy to protect user assets better. 😞
A big shoutout to Yu Xian for the detailed investigation updates!
What’s the point of using advanced technology in crypto if we can’t even protect it from simplest attacks like SIM swaps? 🚨
These constant breaches make crypto feel more like a gamble than an investment. When will the security improve to match the industrys growth?
Its scary out there, but together we can push back against these hackers! Great job, OKX and SlowMist!
The fact that a loophole allowing SMS confirmations for withdrawals even existed is ridiculous. This is basic security stuff, people!
Every step closer to solving this is a win for us all. Thank you for your hard work, SlowMist! 🎉🔬
Why are high-risk security decisions still relying on insecure mechanisms like SMS? This should have been addressed ages ago!
This should be a wake-up call for everyone to enable robust 2FA. Thanks for the heads up! 🔑🚨
This makes me more aware of my own security practices. Thank you for the insights, Yu Xian!
I hope this incident emphasizes the importance of using reliable 2FA methods. Stay strong, OKX & SlowMist! 🔑💪
Great teamwork all around! Lets keep pushing for a safer crypto ecosystem.
Every breach teaches us something new. Here’s to a stronger and more secure crypto future!
Much respect to the team at Dilation Effect for helping to uncover the security loophole! Outstanding work! 💯🔒
Clearly, something is very wrong with the security protocols at OKX. A breach of this magnitude is unacceptable.
Yikes, a SIM swap attack! Glad OKX and SlowMist are working to fix these vulnerabilities.
