Coinbase said an incident at analytics vendor Amplitude exposed the contact data of some customers, but it found no evidence of unauthorized access to its own systems. The incident affected a “small subset” of Coinbase customers and other Amplitude clients, and Coinbase said customer funds were not affected. The disclosure came alongside other reports that day, including South Korean brokerage Daishin Securities, which reported a leak of personal and credit information for 38,490 customers, and a breach investigation at Bithumb. Coinbase had also disclosed a separate data breach in May 2025 affecting less than 1% of its monthly transacting users, with reimbursement and remediation costs estimated at up to $400 million.

- Bithumb discloses data leak after internal system breach: Report
South Korean crypto exchange Bithumb is investigating the extent of a data leak after hackers breached its in-house mobile system, which employees use for internal communication and work, earlier this week. Bithumb discovered the breach on Tuesday and notified the Korea Internet & Security Agency and the Personal Information Protection Commission the same day. The exchange said its internal work system is separated from its virtual asset trading system, so customer virtual assets could not be accessed through this breach, while it was still checking whether member data was involved. The incident is part of a wave of cyberattacks on South Korea's financial sector, with 16 financial firms hit as of October 14, according to Governor Lee Chan-jin. Daishin Securities said personal and credit information of 38,490 customers had been leaked.
- Keystone breach deepens: Hackers stole key used to verify wallets as genuine
Hardware wallet maker Keystone said an attacker who breached its website last week also stole a key used to verify device authenticity, which could let counterfeit wallets pass its checks. The company plans to destroy 18,835 devices in inventory that contain the compromised key and has suspended shipments of devices using it. It disclosed that 25,964 buyer records from 2024 to 2026 were stolen after a faulty data-erasure tool failed to delete them, and that 12,873 checkout records held by Shopify were also taken. Devices made and delivered before the Oct. 20 incident are considered safe, but the authenticity of later devices cannot be guaranteed. The breach follows other security issues at hardware wallet makers this year, including Ledger, Coinkite and Trezor.
- Keystone says website breach exposed hardware wallet buyers’ addresses
Hardware wallet maker Keystone said an unauthorized third party accessed customer shipping information through a website breach, including names, contact details, shipping addresses and order details, after it confirmed the incident on Friday following a review of API activity with Shopify. The company said it has blocked access, fixed the vulnerability, opened an investigation and is emailing affected customers, but did not disclose how many were impacted. Security researcher Taylor Monahan warned the leaked addresses could expose holders to physical attacks and kidnappings, and blockchain security firm CertiK recorded 52 verified wrench attacks worldwide in the first half of 2026, up 33% from the same period last year. Some customers said they received breach notices despite buying devices more than two years ago, raising questions about Keystone’s 2023 pledge to cut data retention to 180 days. Keystone had not responded to Cointelegraph’s questions by publication time.
- Coinbase says user funds are safe after third-party vendor exposes customer contact info
Nasdaq-listed crypto exchange Coinbase denied reports that it was hacked, saying its systems were not accessed without authorization and customer funds remain safe. The incident originated at Amplitude, a third-party analytics provider, and exposed contact information for a small subset of Coinbase customers along with data related to other Amplitude clients. Coinbase is notifying affected customers by email as required by law, but has not said how many were affected or which contact fields were involved. Although passwords, private keys and funds were not compromised, exposed email addresses and phone numbers could still be used in phishing and social-engineering attacks.
- Coinbase Now Offers Fixed-Rate Bitcoin-Backed Loans. Here's What Crypto Investors Need to Know.
Coinbase has offered on-chain loans backed by Bitcoin since January 2025, allowing users to borrow USDC, and on Sept. 22 added fixed-rate versions through Morpho Midnight. These short-term loans must be repaid by the last Friday of the current or following month, and if they are not, the lender can claim the collateral; early repayment still means owing the same interest. Rates are set by supply and demand on an on-chain order book, and Coinbase has not disclosed specific levels. Variable-rate loans allow borrowing up to $5 million in USDC with no set term, while Coinbase has not clarified whether fixed-rate loans share the 75% initial LTV limit and 86% liquidation threshold. The article says these loans may suit short-term cash needs, but Bitcoin's volatility makes them riskier than loans backed by other collateral, and a drop of about 13% could hit the liquidation threshold at the full 75% limit.
- Coinbase Bitcoin ( BTC ) Discount Narrows as Prime Volume Falls 32 %
Bitcoin remained cheaper on Coinbase than on Binance on Saturday, with CryptoQuant's Coinbase premium at -0.13% on Oct. 24, slightly narrower than -0.14% on Oct. 23. Coinbase Prime's Bitcoin volume fell about 32% to 4,959.79 BTC on Oct. 23 from 7,296.83 BTC a day earlier, though this total combines purchases and sales and does not show whether clients bought more than they sold. CFTC data showed leveraged funds held 10,408 short and 5,466 long CME contracts as of Oct. 20, and since the figures are released weekly they may not reflect current market conditions. Other readings cited include a VIX of 19.45 on Oct. 23 and a 10-year U.S. Treasury yield of 4.96% on Oct. 22.

- National Assembly deputies: tighten resale price rules for social housing after 5 years
During the National Assembly's session on October 28 discussing the draft amended Law on Housing, several deputies commented on resale prices of social housing after 5 years. The draft requires that, after 5 years from full payment, buyers may transfer homes only to people eligible to buy them, instead of selling freely on the market as current law allows. Deputy Lý Anh Thư supports curbing speculation but says the draft lacks principles for setting resale prices, which could be based on the original purchase price and an adjustment coefficient; deputy Thạch Phước Bình worries that capping prices too low would limit owners' property rights. Some deputies propose transitional provisions for those who have met or are about to meet the 5-year threshold, and linking housing data with land and population data to manage the whole process of selection, allocation and use.
- Israeli Prime Minister Netanyahu Takes Heavy Blow at Polls
Post-election polls published by major Israeli TV channels, which may contain errors, show voters gave opponents of Prime Minister Benjamin Netanyahu a significant majority in the new parliament. Netanyahu's bloc is projected to win about 50 seats, the opposition about 52 and Arab parties about 18, so forming a government remains uncertain and could take weeks of tense negotiations. Gadi Eisenkot, Netanyahu's main rival and a former military chief of staff, could form a government by cooperating with Arab-led parties, though that could face political obstacles. Turnout reached over 77%, the highest since 1999, and the vote is seen as a referendum on Netanyahu's nearly 17 years of continuous rule. If no bloc secures a majority, Israel could hold a new election early next year.

- Warren Buffett’s Favorite Market Gauge Has Blown Past a Level He Once Called a Warning. History Says This Comes Next.
The article says the Buffett indicator, the ratio of total stock market capitalization to GNP or GDP, now hovers near 237%, above the 200% level Warren Buffett warned about in a 2001 article. The gauge has risen well above its long-term moving average three times in the past 100 years: before the October 1929 crash, during the dot-com bubble of the late 1990s, and in late 2021. After the late-2021 peak, the S&P 500 entered a bear market within weeks and fell 19% the following year. The article discusses approaches such as waiting for long-term returns, building cash and choosing stocks that may hold up during turbulence, and notes that Berkshire Hathaway holds nearly $385 billion in cash. It stresses that history does not always repeat itself.
