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."
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.
A crypto-mining campaign abusing Hugging Face models returned days after takedown, hijacking GPU servers and planting backdoors, with one model downloaded over 28,000 times. Separately, a fake Solana starter kit on GitHub is positioned to trick AI coding agents into installing a NetSupport RAT.
Japan Airlines (JAL) has announced that a data breach at Amadeus’s Passenger Service System exposed the data of about 92,000 customers. JAL Group, which operates the airlines JAL and Japan Transocean Air, uses the system to handle passenger reservations, ticketing, and check-in. According to its announcement, Amadeus notified the airline on October 23, 2026, that unauthorized access to its systems occurred between August 10, 2023, and September 23, 2026. As a result of this lengthy breach, the threat actor accessed reservation codes (PNRs), names, flight dates, routes, and travel classes for approximately 90,000 customers. An additional 2,000 customers had the above data types exposed, plus their email addresses, phone numbers, passport numbers, nationalities, frequent flyer numbers, and flight, ticket, and seat numbers.
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.
