OpenAI says it won't reduce usage limits for the $100, $200, and $500 ChatGPT Pro plans, as well as Business Premium, and it also promised to keep Dots usage independent. In a post on X, Tibo, who is the face of ChatGPT and Codex on X, confirmed that the changes take effect immediately and primarily affect ChatGPT Work and Codex, which share usage allowances under eligible subscriptions. OpenAI had previously planned to reduce the included usage allowance for existing Pro 200 subscribers after October 29, despite keeping the subscription price at $200 per month. However, OpenAI has now reversed that decision following customer feedback. "We are doubling all usage limits for all Pro 100/200/500 tiers and Business Premium, effective today," Tibo announced on X. "We heard your kind feedback and won’t be reducing usage limits for Pro 200, so your Work and Codex usage will stay the same."
Binance probes suspicious crypto transfers worth up to $5.8 billion as Tether and Circle freeze $1.79 billion in stablecoins linked to the activity. Binance is investigating a potential security incident after billions of dollars in cryptocurrency moved from wallets linked to the exchange on October 29. The transfers raised concerns about a possible hack, while Tether and Circle moved to freeze stablecoins linked to the suspicious activity. The full scope of the incident remains unclear, and the reported outflows shouldn’t automatically be treated as confirmed losses. According to The Block, blockchain analyst Spreek identified approximately $3.55 billion in incoming transfers to an initially unidentified wallet. “Onchain data flagged by analyst Spreek shows about $3.55 billion in incoming transfers to the unlabeled wallet, with nearly $900 million subsequently moved across other wallets.” The Block reports. “Conor Grogan, a senior director and product leader at Coinbase, says the amount is up to $5.8 billion.” Coinbase executive Conor Grogan estimated that the total value of the movements could reach $5.8 billion. I think the number is potentially up to $5.8B. Tether has blacklisted a large portion of this. https://t.co/ANz2DiXc8S pic.twitter.com/BfscU7ENSo — Conor (@jconorgrogan) October 29, 2026 These figures come from blockchain tracking and different estimates, so they don’t necessarily represent the amount stolen. BREAKING: The Binance hack has grown to about $5.6B drained across Ethereum, Bitcoin and Tron, on-chain trackers say. If confirmed, it would be the biggest crypto heist on record. Tether and Circle have frozen about $1.8B in stablecoins, and Circle says it acted "in… https://t.co/UzgOxw9jLE pic.twitter.com/9fBEaaZrWj — International Cyber Digest (@IntCyberDigest) October 29, 2026 Binance acknowledged the reports and said its security team was investigating. The company had not publicly confirmed a breach in the initial reports, making it important to distinguish between suspicious transactions and a verified compromise. “We are aware of reports of a potential security issue and we are actively investigating.” He wrote in a post on X. “Our security teams are reviewing all relevant information with urgency, and we will provide updates through official Binance channels as soon as we have verified information. Users should remain cautious of scams and should not trust unofficial links, messages, or requests for account information.” We are aware of reports of a potential security issue and we are actively investigating. Our security teams are reviewing all relevant information with urgency, and we will provide updates through official Binance channels as soon as we have verified information. Users should… — Yi He (@heyibinance) October 29, 2026 This statement, reported by The Block, reflects the company’s position at the time. Binance also urged users to be cautious of unofficial messages and links, a relevant warning whenever a major security incident attracts public attention. Blockchain records showed large transfers from Binance-linked hot wallets to a wallet that wasn’t previously identified as belonging to the exchange. Hot wallets hold cryptocurrency in systems connected to the internet, allowing exchanges to process withdrawals and other transactions quickly. Their online availability also makes their security controls particularly important. The transfers involved Ethereum, stablecoins and other cryptocurrencies. Some funds were later moved to additional wallets, making it harder to track all the transactions. Investigators must determine who initiated the transfers, whether they were authorized and whether an attacker gained control of the wallets. They also need to establish whether the funds belonged to customers or Binance itself. Large transfers alone don’t prove a hack. However, unusual movements involving large amounts of cryptocurrency require immediate investigation. One of the most significant developments was the response from the companies behind two major stablecoins, USDT and USDC. According to The Block and Forbes, Tether and Circle froze approximately $1.79 billion in stablecoins associated with the suspicious transfers in the initial reports. The figures subsequently changed as the investigation developed. Tether CEO Paolo Ardoino later said the company had frozen more than $1.567 billion in USDT linked to a potential Binance exchange hack. These amounts reflect reported actions at different points in time and shouldn’t be combined without checking whether they refer to distinct assets and addresses. Tether froze more than 1.567B USDT related to a potential Binance exchange hack. Protecting the industry and our partners is our main priority. Stay safe everyone. — Paolo Ardoino (@paoloardoino) October 29, 2026 The freezes demonstrate an important feature of centralized stablecoins: their issuers can restrict transfers from addresses they control through their token contracts. This can help contain suspected theft, but it doesn’t provide the same control over assets such as Ether or Bitcoin. Nor does freezing a balance guarantee that every transferred asset can be recovered. The incident also highlights a practical tension in crypto security. Stablecoins offer the convenience of blockchain transfers, but their centralized issuers retain powers that can make a difference during an investigation. Binance maintained that customer funds were safe, while co-founder Changpeng Zhao, widely known as CZ, said the activity appeared to be a hack. Zhao no longer manages Binance’s platform, but said he expected customers’ funds to be fully covered. The company said its user funds were “completely safe.” “Our teams are aware of reports of a potential security issue and are actively investigating. User funds are completely safe. Our security teams are reviewing all relevant information with urgency, and we will provide updates through official Binance channels as soon as we have verified information.” the company states. “Users should remain cautious of scams and should not trust unofficial links, messages, or requests for account information.” That assurance is important, but it doesn’t replace a technical explanation of how the transfers occurred or independent confirmation of the final impact. A security investigation must establish more than whether an exchange can cover a potential loss. It should determine how the activity was authorized, whether credentials or signing mechanisms were compromised, which systems were involved and whether the attacker retained any access. For customers, the immediate priority is to avoid becoming a secondary victim. Attackers often exploit uncertainty around a major incident to distribute fake announcements, impersonate support staff and direct users to fraudulent websites. Users should rely on official Binance communication channels, avoid unexpected links and never disclose passwords, authentication codes or wallet recovery phrases in response to unsolicited messages. Security teams should also watch for phishing emails that use the incident to demand urgent account verification. Attackers may exploit the situation to launch a separate scam. The key lesson is that blockchain transparency does not guarantee operational security. Public ledgers show transactions, but they don’t reveal who authorized them, how attackers may have gained access or whether an exchange’s internal security controls failed. As the investigation continues, it’s important to distinguish between reported transfers, confirmed theft and funds that can be recovered. The figures may change as analysts trace more wallets and stablecoin issuers take further action.

Cryptocurrency exchange Binance is investigating a potential security breach involving up to $5.8 billion in digital assets, in what could become the largest cryptocurrency hack in history. If confirmed stolen, the amount would far exceed the $1.5 billion stolen from Bybit by North Korean hackers in February 2025, the largest confirmed crypto heist on record. The suspected breach has already prompted stablecoin issuers Tether and Circle to freeze more than $2.3 billion in assets associated with the incident. In a statement to BleepingComputer, a Binance spokesperson confirmed that the exchange was investigating reports of a potential security issue while reassuring customers that their funds were safe. "Our teams are aware of reports of a potential security issue and are actively investigating. Rest assured that user funds are completely safe," the spokesperson told BleepingComputer.

The Pentagon treats August freezer failures at US military bases as a suspected hack and is working with French investigators after a supermarket attack. The Pentagon is investigating freezer failures that spoiled food at US military bases in August as a suspected cyberattack, according to four officials who spoke to Reuters. One official said US investigators are also in contact with French authorities about a similar attack on commercial freezers that disrupted supermarkets in France earlier this month. This is the first time Reuters has reported that the US incident is being treated as a suspected cyberattack. “The Pentagon is treating the spate of mysterious freezer malfunctions that spoiled food at military bases across the United States in August as a suspected hack, according to four officials familiar with the matter.” Reuters reports. “One of the officials said the military investigators were in touch with their French counterparts about a similar cyberattack on commercial freezers that disrupted supermarkets there earlier this month.” It is still unclear who is behind the attacks. Reuters could not determine how far the investigation has progressed or whether investigators have identified the cause or those responsible. The Pentagon said a unit of US Cyber Command is working closely with other government agencies and law enforcement. The Army’s Criminal Investigation Division confirmed that its Cyber Field Office is involved and is working with French law enforcement to investigate the freezer outages in Europe. The incidents hit commissaries, the on-base stores where military personnel buy food. At least six were affected in late August, according to Reuters’ review of the bases’ Facebook posts and website updates. Stars and Stripes named Fort Irwin, F.E. Warren, Naval Station Newport, Columbus and Travis among the confirmed stores, and some outlets count up to 14 sites in 11 states, though not all are confirmed. Source: Signal and Silence Blog Source: Signal and Silence Blog In at least one case the freezers didn’t just stop. Their temperatures were cranked up overnight, which left mounds of wilted or melted food in the morning. Fort Huachuca in Arizona said on August 26 that its freezer went into defrost mode and heated up all the food, adding that trust us when we say it was spoiled. The Pentagon wasn’t the first to speak. A recently created blog called Signal and Silence reported the freezer failures and the possibility of sabotage on August 28, while Stars and Stripes reported the involvement of military investigators and Britain’s Daily Telegraph reported the contacts with the French. The French Embassy in Washington had no comment. Frozen food is the one asset where damage takes hours and evidence takes the form of puddles. The French attack is the clearest example. Hackers took control of the cooling units in more than 350 stores and raised the temperatures. Frozen food aisles were emptied, and some units got so hot they caught fire. One supermarket owner said the total cost could reach tens of millions of euros. The same thing happened in Arizona: attackers made the units hotter instead of just turning them off. Reuters could not tell which brand was used at the US bases, and Danfoss, which is the manufacturer targeted in French supermarket attacks, did not reply. A public research report on Danfoss controllers came out before the incidents, but nothing shows a link to the bases. There is a history of attacks on refrigeration systems. Danfoss reports that hackers targeted supermarkets in Russia and Israel in 2022 by exploiting outdated cooling controllers. In December 2025, US prosecutors accused a Ukrainian woman of belonging to a hacking group that disrupted refrigeration at a meat plant in 2024, ruining more than 2,000 pounds of meat. Earlier this year, the Global Food Safety Initiative urged food safety experts and IT leaders to work together to protect refrigeration systems.

Prediction market platform Polymarket temporarily suspended trading on Thursday after hackers compromised a third-party service to distribute cryptocurrency-draining JavaScript, with approximately $2.5 million in assets traced to a suspected attacker wallet.
A fake cryptocurrency trading app called Padre Terminal, previously available on the Apple App Store for iOS devices, has been linked to the theft of approximately $23,000 from 27 Solana wallets. Blockchain investigator Iris confirmed that one victim was compromised through the malicious App Store app, but has not determined how the other affected wallets were compromised. The researcher says the app drains wallets after unsuspecting users import their private keys into it. Padre was a cryptocurrency trading platform, mainly used to buy and sell meme coins on Solana. It was later renamed Terminal by pump.fun, a platform focused on creating, buying, and selling cryptocurrency “meme coins” on the Solana blockchain. Iris says the legitimate Padre trading service, now Terminal by pump.fun, is web-only, so any mobile apps impersonating it, including the one previously available on the App Store, are malicious.
Some attacks take real skill. Others just need someone to leave a door open. This week has both. Exposed passwords, old bugs still getting exploited, and trusted software doing things it shouldn't. There's a strange mix of clever tricks and careless mistakes. Hackers are borrowing trust from familiar apps, websites, and AI tools. Some are using AI to speed things up. Others are leaving their
A newly identified advanced persistent threat (APT) group tracked as UAT-11473 was observed exploiting CVE-2026-20127, an authentication-bypass flaw in Cisco Catalyst SD-WAN Controllers, to deploy a custom malware framework called KeyDrift. CVE-2026-20127 is a max-severity flaw that Cisco patched in February 2026, which allows remote attackers to gain privileged access to Catalyst SD-WAN Controller and Manager and add rogue peers. UAT-8616 has exploited the vulnerability as a zero-day since at least 2023, and recent research also linked its exploitation to the Chinese Volt Typhoon state-sponsored hacking group. According to Cisco Talos researchers who reported on the activity, the UAT-11473 threat cluster appears to overlap with Volt Typhoon’s "Silent Train" covert access network, but they made no definitive links.
A massive search-hijacking campaign involving 319 Chrome extensions with a combined 13.4 million reported installations redirected users' searches through tracking servers to generate advertising revenue from Bing and Yahoo. A new report by Socket's John Tuckner expands on the researcher's April 2025 discovery of 57 Chrome extensions with 6 million users, adding 264 newly identified add-ons with another 8.7 million users. "These extensions were created by a handful of organized operators all working from the same idea: quietly take over the browser's default search engine, route every query through a suspicious proxy server, and collect partner referral payments from Yahoo or Bing under a syndication partner ID," explained Tuckner. The extensions, with the full list shared at the bottom of Socket's report, pretend to be PDF converters, manual finders, safe search, and AI search tools. However, for the most part, the extensions simply redirect users' searches through a series of sites until they land on Bing or Yahoo.
