David Robinson, an executive from OpenAI's safety systems team, left last week. Robinson was previously responsible for OpenAI's policy planning and played a significant role in enhancing model transparency, including the development of system cards.This departure marks another personnel change in OpenAI's safety department, as safety lead Johannes Heidecke also left earlier this year. The company announced on Thursday that it parted ways with three researchers for violating sensitive information sharing policies.Amid the backdrop of security vulnerabilities at Hugging Face and a series of abnormal behaviors in AI models, CEO Sam Altman stated at the developer conference on Tuesday that safety and alignment work must stay ahead of the development of model capabilities. Before his departure, Robinson publicly expressed concerns, believing that while OpenAI is undergoing significant changes, there remains uncertainty about whether the pace of transformation is sufficient to address the challenges posed by high-performance AI models.

The cryptocurrency exchange platform Coinbase has obtained a Financial Services License (FSP) issued by the Financial Services Regulatory Authority (FSRA) of the Abu Dhabi Global Market (ADGM). This license allows it to arrange investment transactions and provide custody for tokenized securities. Coinbase describes this license as the regulatory foundation for its international tokenization hub and the first of its two major non-U.S. institutional businesses established in the UAE, the other being its derivatives business in Dubai.According to the scope of the license, the FSP covers the arrangement and custody of tokenized stocks fully backed by underlying shares. Holders of digital securities can gain economic exposure such as dividends, while voting rights and redemption rights are subject to the conditions outlined in each prospectus. Coinbase states that investors only need a crypto wallet to trade, and secondary transfers do not require a brokerage account or banking relationship, but redeeming profits for fiat currency still requires a bank or brokerage account.Brett Tejpaul, Co-President of Coinbase Institutional: Currently, there is no major financial center that has established a framework that simultaneously regards tokenized stocks as securities, blockchain-native tokens, and composable DeFi assets. Arvind Ramamurthy, Chief Market Development Officer of ADGM, stated that the Coinbase hub reflects the center's progressive, robust, and internationally aligned regulatory framework. The FSRA issued its first virtual asset rules in 2018, which include protective measures such as sanctions screening and the ability to freeze or seize assets at the wallet level. ADGM applies English common law, and the FSRA's authority differs from that of the UAE Securities and Commodities Authority; registered entities do not automatically obtain a passport in other Gulf Cooperation Council jurisdictions.

NEAR co-founder @ilblackdragon revealed on the X platform that the recovery of stolen funds from NEAR Intents was mainly due to the AI security layer SHIELD on Intents, as well as some proactive investigative work.The Intents team identified the responsible party and established communication within less than 24 hours of the hack, successfully recovering the funds in full today at 14:30 UTC.@ilblackdragon also stated that NEAR will continuously strengthen its security systems and further adapt to the ever-changing cybersecurity landscape. While AI may accelerate the exploitation of vulnerabilities, it can also help us defend against them. It is hoped that the entire industry will respond with vigilance and feel the same sense of urgency to collaborate together.

The Chairman of the U.S. Securities and Exchange Commission (SEC), Paul Atkins, issued a statement saying that the Commission proposed a plan this week to fill the regulatory gap regarding the custody of cryptocurrency assets by investment advisors and funds, providing a clear custody framework and compliance path for an asset class with increasing client demand.Atkins stated that the existing custody rules under the Investment Advisers Act of 1940 and the Investment Company Act of 1940 were established before the advent of the internet, primarily targeting traditional assets and requiring the use of approved custodians. The custody capabilities for new cryptocurrency assets often lag behind the launch of the assets by several months. This proposal aims to address this issue while updating the custody rules for advisors and regulated funds that have not been revised for decades to align with current industry practices and feedback.The statement noted that this proposal is part of the SEC's regulatory framework for cryptocurrency assets. Related efforts include stopping the replacement of regulation with enforcement, issuing a no-action letter regarding the pilot program for the tokenization of securities by custodial trust companies by December 2025, publishing a classification description for tokenized securities in January 2026, and subsequent initiatives regarding the securities attributes of cryptocurrency assets, broker registration, Regulation Crypto Assets, and innovative exemptions for trading tokenized NMS stocks. Atkins indicated that more regulatory proposals will be forthcoming.

Atkins stated that the current custody provisions of the Investment Advisers Act and the Investment Company Act predate the birth of the internet, and the custody capabilities for new assets often lag behind by several months after they go live. The SEC's proposed custody rules aim to fill this gap.Atkins also compiled the current SEC's cryptocurrency regulatory initiatives, including ending "regulation by enforcement," arrangements related to tokenized securities, the proposed framework for Regulation Crypto Assets issuance, and "innovation exemptions," stating that more regulatory proposals are on the way.

On October 2, at 11:30 AM Eastern Time, the Arbitrum Security Committee executed an emergency upgrade on Arbitrum One and Nova, suspending the activation of all new Stylus contracts on both chains, while adding a protective mechanism against BoLD single-step proofs in the dispute system of Arbitrum One. The Arbitrum Foundation stated that this action is part of ongoing proactive security measures aimed at protecting the security and integrity of the network.Stylus allows developers to write smart contracts using languages such as Rust and C++, while maintaining compatibility with the Ethereum Virtual Machine, with its programs compiled into WebAssembly format. This suspension primarily targets manually written WASM programs that do not use the standard Stylus compiler toolchain and have not yet been patched by the current version of ArbOS. The Security Committee increased the gas required for activation to the theoretical maximum by calling ArbOwner.setWasmActivationGas(2^64 - 1), making new activations economically unfeasible. Activated Stylus contracts are unaffected and can continue to execute and renew, and the deployment and execution of Solidity contracts are also unrestricted.The newly added BoLD protection allows anyone to pause the settlement from Arbitrum One to Ethereum when two conflicting and accepted answers appear in the same dispute step, which may delay unconfirmed withdrawals to allow the Security Committee to deploy fixes. Officials pointed out that the currently discovered Stylus-related vulnerabilities mainly affect the activity of the chain, such as denial-of-service attacks, and do not jeopardize user funds.

According to Decrypt, the European Union's law enforcement agency reported that Spanish police arrested a 16-year-old Romanian suspect in Alicante, suspected of being an administrator and main operator of the ransomware group KillSec.Two other suspects in their twenties were arrested in the UK and Romania, respectively; another developer who just turned 18 in August this year has been identified but has not been arrested due to some crimes occurring during their minor years.This operation, codenamed Operation KillSwitch, was led by the Hamburg State Criminal Police and the city's prosecution office, focusing on approximately 1,000 suspected attacks worldwide, with about 500 confirmed as successful intrusions.Law enforcement searched eight locations in Spain, Greece, Romania, and the UK, seized five central servers, and redirected related domain names to seizure announcement pages, while also confiscating at least 110 TB of stolen data.KillSec has been active since around 2024, exploiting software vulnerabilities and poorly secured cloud storage entry points to infiltrate corporate systems, copying internal data and naming victim organizations on dark web leak sites, threatening to publicly release documents to demand cryptocurrency ransoms, and if the target refuses to pay, they release the data for free.The Swiss Federal Police noted that the group also employed double extortion tactics, first encrypting servers and then applying pressure. U.S. prosecutors' charges indicate that a Dutch national residing in the UK, Fouad Eltibrizi (nicknamed Archduke), was indicted by a federal grand jury in Puerto Rico on September 16, subsequently arrested, and awaiting extradition, facing up to 10 years in prison. The European Cybercrime Centre, under the European Union Agency for Law Enforcement Cooperation, is assisting in tracing cryptocurrency funds and conducting digital forensics.

The Financial Services Commission of South Korea has proposed regulatory guidelines for the issuance and trading of security tokens, intending to allow stocks, bonds, funds, and certain fractional investment securities to be issued and circulated in token form. The relevant regulatory framework is scheduled to take effect on February 4, 2027.According to the proposal, securities token issuance companies that directly manage client accounts must have a paid-in capital of at least 4 billion Korean Won and be equipped with dedicated compliance and technical personnel. The revision of capital market regulations will also introduce an over-the-counter trading license for bonds and limit individual investors' annual net purchases at each over-the-counter exchange to within 100 million Korean Won.The proposal will be open for public consultation from Friday until November 11, after which it will enter the approval process. South Korea previously announced a roadmap to advance the transition of securities issuance and trading to distributed ledger infrastructure in three phases.

The SEC recently made public the comments submitted by Stove Finance regarding the exemption for tokenized stocks.The comments focus on the infrastructure issues after tokenized stocks enter the on-chain market, including asset conversion between traditional securities systems and on-chain ledgers, inventory replenishment, reconciliation, and how corporate actions such as dividends and stock splits maintain consistency across different systems.Stove suggested in the comments that registered broker-dealers be allowed to further participate in the construction of on-chain securities record, reconciliation, and delivery infrastructure, and that a unified standard for asset conversion, settlement status, and corporate actions be established collaboratively by broker-dealers, custodians, transfer agents, and on-chain trading venues.As tokenized stocks gradually enter DeFi scenarios such as AMM and liquidity pools, settlement, asset services, and cross-system interoperability beyond trading are becoming the next issues that the industry needs to address.

According to The Block, Robinhood's Senior Vice President of Cryptocurrency, Johann Kerbrat, stated during the 2026 Korea Blockchain Week that the company is still advancing work related to the "innovation exemption" with the U.S. SEC to support its tokenized stock business.Kerbrat mentioned that as the scale of stock token trading grows, its trading volume may reach the relevant limits set by the SEC.
