Binance says hackers spent months infiltrating its systems through fake job interviews, a tampered developer tool and compromised internal AI tools before stealing $6.34 billion in crypto in the Oct. 29 attack. Co-CEO Richard Teng said Binance has replenished 98% of the affected assets, and that it is still in the process of purchasing outstanding, more illiquid assets. CNBC reports: Preparations for the attack began in June, when a Binance Wallet DevOps engineer downloaded a tampered Homebrew installation "to install a popular AI coding tool after searching for it on a search engine," according to a security report published by Binance Tuesday. It said it detected the suspicious activity, replaced the engineer's device and rotated credentials as a precaution, but that by then the employee's "role and his related colleagues on our wallet infrastructure team was exposed to the hacker." [...] As of Tuesday Binance has rebuilt the affected wallet system and internal AI tool, replaced compromised devices, decommissioned credentials and tokens associated with the affected engineers and expanded security scans across employee devices, Teng told "Squawk on the Street." "We're also getting an independent expert to review everything that we have done, and we'll keep strengthening our defenses as the investigation continues," Teng said. "We're working around the clock with law enforcement agencies and with industry partners to trace and freeze the stolen funds for that front."

UPDATE 10/30/26: Binance has temporarily suspended customer withdrawals after suffering what investigators say is the biggest crypto hack in history. According to Binance CEO Yi He, the company estimates roughly $6.3 billion in funds were impacted, with roughly $3 billion in assets frozen on-chain so far. Rest assured, "your money is safe, and we're covering every loss," said co-CEO Richard Teng in a LinkedIn post. "This was a complex attack," said Teng. "The attacker also used a self-destruct mechanism that destroyed tooling and tracers, making it more difficult for us to trace." From a report: Teng said the incident was not carried out by one person. While the initial investigation indicated the involvement of a compromised laptop, further digging revealed additional points of breach. [...] Blockchain analysis firms TRM Labs and Elliptic have linked the theft to North Korean hackers, with TRM attributing it "with high confidence" to a group known as TraderTraitor, the same group responsible for last year's Bybit hack. Elliptic estimated Friday that about 44% of the stolen assets have been frozen, with stablecoins accounting for nearly all of those funds. The firm estimated that attackers still controlled over $3 billion in crypto that token issuers cannot directly freeze. The hackers appear to have compromised Binance's wallet-signing infrastructure, allowing them to authorize transactions that drained billions of dollars in cryptocurrency across multiple blockchains, according to the firms. Binance, in its preliminary stage, has conducted an investigation into the hack, which suggests the incident may have begun with a compromised engineer's laptop. The exchange added that it has found no evidence that wallet passwords were leaked. Below is the original story from yesterday, Oct. 29th. Binance is investigating a potential hack after more than $2 billion in crypto was drained from one of its wallets into a new external account, with Blockaid estimating nearly $3.3 billion was moved. "Our teams are aware of reports of a potential security issue and are actively investigating," said Binance on X. "User funds are safe," said Binance founder CZ. "It does look like a hack on Binance. Appreciate the quick freeze from Tether (~$971m) and Circle (~$823m). I don't manage Binance anymore, but as a shareholder, I expect all user funds will be fully covered." At around the same time, crypto-based prediction market Polymarket reported its own security incident that wiped out around $2.7 million in user funds.

Intel, Oracle, IBM and IonQ have joined a growing list of companies objecting to having tokenized versions of their shares traded through OKX and Intercontinental Exchange's blockchain venture, bringing the total number of objections to 26. About 37% of the companies on OKXICE's original list have now opted out, according to CoinDesk. From the report: The four companies were named in an updated public notice (PDF) dated Monday, Oct. 26, from OKXICE, the two firms' joint venture. They join earlier objectors including Microsoft, Alphabet, Goldman Sachs, Cisco and Wells Fargo. The growing list underscores a hurdle for OKXICE and the SEC's new framework for tokenized stock trading: building a market that issuers are willing to join. The agency's five-year "Innovation Exemption" gives qualifying venues room to test round-the-clock blockchain-based trading of stocks, and it also gives public companies an option to block their shares from being offered. OKXICE issued its initial public notice on Oct. 4, outlining plans to use Uniswap v4 liquidity pools on OKX's XLayer blockchain, with transactions settled in stablecoins. The venue would use automated market makers -- software that executes trades through pools of assets rather than matching buyers and sellers through a conventional order book. Under the framework, venues must notify issuers and give them 30 days to object before offering tokenized versions of their shares.

California Gov. Gavin Newsom has signed AB 2409, barring California public officials from issuing memecoins and prohibiting companies from listing memecoins that use a public official's image or likeness. Engadget reports: The governor's office pointed to reports that about a million investors lost an alleged $3.8 billion on their purchases of the memecoin released by President Donald Trump in 2025 as a the motivation behind the new rule. "No official should profit off their office -- and we're putting stronger protections in place to ensure it doesn't happen in our state," Newsom said. The bill also prohibits a company, related or not, from making a memecoin using "the likeness or image" of a public official.

August 15: $62,991 September 23: $86,456 Bitcoin shot up 37% over the last 39 days, reaching an eight-month high on Monday. "Bitcoin is back," declares Yahoo Finance: The token held near $86,000 on Tuesday after a stunning multisession rally... [Fundstrat head of digital assets Sean Farrell told Yahoo Finance on Monday] "I think the crypto winter is over, although that does not necessarily mean the path higher will be linear." For now, momentum is on crypto's side, with bitcoin jumping more than 5% on Friday and another 6% on Monday. "We believe crypto is in the early innings of a new bull market and we see few signs of overheating," Compass Point analyst Ed Engel wrote on Tuesday. The move looks "like a combination of renewed ETF demand and a large short squeeze," Nicolai Søndergaard, senior research analyst at Nansen, said as traders betting against bitcoin are forced to buy it back, adding further fuel to the rally. Bitcoin got bad news and then good news last week. After the U.S. Congress failed Thursday to pass a cryptocurrency 'Clarity Act', America's Securities and Exchange Commission instead announced a tokenized-stock experiment. It's a five-year "innovation exemption" that "creates a path for tokenized U.S. stocks to trade through automated market makers on public blockchain," according to CoinDesk. Yahoo Finance notes that Bitcoin and other altcoins surged after the announcement.
