Roughly $6.3 billion in digital assets were reportedly affected in an October 2026 security incident at Binance, the world’s largest cryptocurrency exchange.
Binance initially linked the breach to a compromised DevOps engineer’s laptop. The company later indicated the attack was more complex than a single-device compromise, according to reporting by Yahoo Finance and Fortune.
Around $3 billion in assets had reportedly been frozen through cooperation with law enforcement, blockchain-intelligence firms, token issuers, and industry partners, according to Binance.
Two cryptocurrency-tracing firms connected the attack to TraderTraitor, a hacking operation with reported ties to North Korea. That attribution remains preliminary and has not been confirmed.
How Musk Responded on X
As breach reports circulated, Musk posted “Everyday is Zeroday,” a phrase that references the recurring exploitation of security vulnerabilities that have not been adequately addressed.
When CZ pledged that Binance would cover all affected users’ losses, a third-party user compared Binance to FTX, the cryptocurrency exchange that collapsed in 2022 amid fraud allegations. According to reporting by Yahoo Finance and CNBC, Musk replied with a grimacing-face emoji.
Musk later responded to a CZ post warning users about phishing emails and computer viruses with laughing and fire emojis, the same reporting found. CZ replied that the breach was more complicated than that description implied.
CZ Pushed Back Directly, and Brought Up the Money
CZ wrote on X that he had “a lot of respect” for Musk but called it a “bad time to troll” and asked him to stop.
His directive was brief: “Please stop.”
CZ also pointed to a financial connection between the two. Binance’s investment tied to Musk’s 2022 Twitter acquisition was worth more than $1 billion, CZ said, and Binance’s holdings in “SPCX” exceeded $1 billion as well. Those figures are CZ’s claims and have not been independently verified.
The appeal combined a public reprimand with a financial argument. CZ surfaced Binance’s economic stake in Musk-related assets, reframing what began as a social media exchange into something closer to a business dispute.
$6.34 Billion Reserved, With Work Still Ahead
Binance said it had reserved more than $6.34 billion in company funds to cover the security incident, though those figures require direct confirmation from the company’s official announcement.
CZ estimated in a separate post on X that frozen assets and Binance’s SAFU fund could cover much of the total loss, leaving an approximate $2 billion gap. SAFU, which stands for Secure Asset Fund for Users, is a reserve Binance maintains specifically to protect customers in emergencies.
Binance said it was cooperating with law enforcement and blockchain-intelligence firms to recover additional funds. The investigation remains active, and no culprit has claimed responsibility or been publicly identified.
