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.
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.
AI agents can control authenticated browsers, interact with corporate applications, and access sensitive data while appearing to act as legitimate employees. Keep Aware examines three ways agents operate inside browsers and why traditional security tools may struggle to distinguish their activity from human users.
A flaw in Telegram for Android could be chained with two other bugs to take full control of a victim's phone through a voice call, once the victim answered, according to security startup NebuSec. The attacker needed only an ordinary Telegram account. Telegram fixed the flaw in version 12.10.4 of the app, released in late September, and NebuSec disclosed it on October 29. Combined with an
US election websites show improved security, but weak email protection, non-.gov domains and third-party tracking still expose voters to risks. Millions of Americans will use websites to check their registration, find polling places or track ballots before the November 3 election. However, a new study finds that many county election websites still have security weaknesses involving domain names, email authentication, encrypted connections and third-party tracking. Mysterium VPN’s 2026 County Election Website Security Census examines 2,081 county election websites across the United States. “42% of county election websites aren’t on .gov (869 of 2,081 identified). That’s down from 57% in 2024.” states the report. “Weighted by population, it’s 28% because the big counties moved first.” That’s an improvement from 57% in the company’s 2024 census. However, the findings reveal persistent weaknesses that could expose voters to impersonation, misleading websites and unnecessary data collection. These findings concern public information websites and their contact domains. They do not establish that voting machines, ballot-counting systems or election results have been compromised. The researchers started with 3,144 US counties and county equivalents but identified county-run election information pages for 2,081. Of these, 869 used domains outside .gov. Only verified US government organizations can register a .gov domain, making it a useful way for voters to identify official government websites. The study found that larger counties had made more progress: when weighted by population, 28% of residents lived in counties whose election pages used non-.gov domains. Texas accounted for 169 non-.gov sites, including 134 using the older co.<county>.tx.us structure. Arizona and Nebraska had no identified non-.gov county election sites. The FBI and CISA previously warned that criminals were using fake election websites to spread false information and collect personal data. Moving to .gov and redirecting older addresses can reduce confusion, although the domain alone cannot guarantee that every aspect of a website is secure. Election offices communicate with voters about registration, identification requirements and missing ballots. Weak email authentication can make it easier for attackers to impersonate these offices. Of 1,977 readable election pages, 965 displayed a contact address. After excluding consumer email services, researchers examined 942 county-controlled domains. “Of the 1,977 election pages whose content we could read, 965 display a contact address. Twenty-three of those are at consumer providers like Gmail. As in 2024, we set them aside, because Gmail’s security policy is Gmail’s, not the county’s.” states the report. “That leaves 942 county-controlled election email domains.” The study reported that 23% had no DMARC record, while 28% used p=none, a monitoring-only policy that does not request quarantine or rejection of unauthenticated messages. Another 30% requested quarantine and 19% rejection. Together, the first two groups account for roughly 51% of domains without an enforced DMARC policy. The report’s underlying counts total 941 rather than the stated 942, a discrepancy that requires clarification. The share of domains without DMARC fell from 41% in 2024 to 23% in 2026. SPF, another email authentication mechanism, was present on 98% of checked domains. Smaller counties performed worse. Among the third of counties with the fewest residents, 34% of election contact domains lacked DMARC, compared with 12% among the largest counties. Non-.gov domains also showed weaker protection: 32% lacked DMARC, compared with 16% of .gov domains. These findings indicate an association, not proof that adopting .gov automatically improves email security. DMARC enforcement can reduce certain forms of domain spoofing, but it cannot prevent every impersonation attempt, lookalike domain or attack involving compromised accounts. The researchers found 28 websites with consistent HTTPS failures among the 2,081 tested. Fifteen lacked a working HTTPS service, seven presented certificates for the wrong domain, and others had expired or untrusted certificates or failed to establish a secure connection. Another 178 websites would serve election pages over unencrypted HTTP if visitors requested them that way. Only 34% sent an HSTS header, which instructs compatible browsers to insist on encrypted connections. Sixty-three certificates were due to expire within 30 days of Election Day. A separate test examined third-party connections when election pages loaded in a clean browser, without clicks or scrolling. Of 1,930 measured pages, 84% contacted at least one company identified as a tracker by Disconnect or DuckDuckGo. The median page contacted six third-party domains. Google Analytics or Tag Manager appeared on 60% of websites, while Meta Pixel appeared on 3%. Mysterium suggests that some tracking results from default settings in website platforms rather than deliberate decisions by election officials. The presence of third-party code does not, by itself, establish unlawful tracking or prove exactly what information was collected. Still, counties should review whether these connections are necessary on pages designed to provide basic voting information. The study examined recognizable election-related domain names across several extensions, including .gov, .com, .org, .net, .us and .vote. Researchers identified 2,074 matching names that resolved to an address. Of these, 121 were registered outside government control. Thirty-eight hosted unrelated websites, eight were offered for sale, 73 displayed basic server or hosting pages, and two served gambling or spam content. The researchers also found 73 counties with a working .gov version of the name used by their non-.gov election website, suggesting that some had secured the official address without completing the migration. A separate test generated 14,456 single-character misspellings of 77 state and large-county election domains. Researchers found 245 registered variants and identified 26 that served parked, placeholder or unrelated pages after excluding potentially coincidental matches. The study does not establish that these registrations were malicious or identify their owners. However, a voter who mistypes an address or guesses the wrong domain ending could reach a third-party website instead of an official source. Across the seven states that decided the 2024 presidential election, 43% of identified county election websites were outside .gov, down from 55% in 2024. In these states, 26% of election contact domains lacked DMARC, compared with 39% two years earlier. However, 55% still lacked an enforced policy. The nine states whose 2026 Senate races were rated toss-up or lean in mid-October showed similar concerns: 53% of identified county election sites were outside .gov, while 44% of election contact domains lacked enforced DMARC. These figures measure website and email configurations. They are not evidence that an election has been compromised. Mysterium recommends that eligible government organizations complete the move to .gov, redirect old addresses, enforce email authentication policies and configure HTTP-to-HTTPS redirects and HSTS. Counties should inventory legitimate email senders before tightening DMARC policies to avoid disrupting valid communications. They should also review advertising pixels and unnecessary third-party connections, monitor certificate expiration dates and consider registering defensive versions of their domains. For voters, the report recommends starting with the state election office listed on USA.gov and following its link to the relevant county website. Voters should avoid trusting unsolicited messages or plausible-looking search results without checking the destination. If an election-office email comes from an unexpected address, voters should verify it using an independently obtained official telephone number. An unusual address is a reason to check, not proof of fraud, since the study found that some legitimate offices still use consumer email services. The researchers combined Census Bureau county data with official websites recorded in Wikidata and checked them against CISA’s .gov registry. They tested displayed contact addresses, email authentication records, certificates, redirects, tracking requests and lookalike domains. The study identified 2,081 election pages, compared with 2,913 in the 2024 manual survey. Automated discovery favored larger counties with better-structured websites, leaving smaller counties underrepresented even though some had weaker protections. The comparisons indicate progress but are not a perfectly matched before-and-after assessment. Different tests also used different sample sizes, and the tracking analysis measured a single page load from one location. The observations reflect October 17, 2026, rather than continuous monitoring. The findings provide a useful snapshot of public-facing election website security, but individual results should be rechecked before drawing conclusions about a specific county.

Third-party Android app stores can now apply to Google for permission to install apps with one tap, without Android's usual confirmation screens, and to update them in the background. To qualify, a store must pass identity checks and send Google its full catalog, along with every new app and update, for ongoing malware scanning. Approved stores get the features from December 1, but only on
Microsoft again asked Entra ID administrators to migrate users to phishing-resistant methods to avoid sign-in disruptions before it retires SMS and voice authentication in February 2027. This retirement process applies only to Microsoft Entra ID workforce tenant authentication scenarios and not to Azure AD B2C or Microsoft Entra External ID customer identity scenarios. Before Microsoft retires SMS and voice authentication, admins should ensure all users in their organizations use a phishing-resistant method, since they will no longer be able to use them to complete multifactor authentication and log in to their accounts. Admins can choose from passkeys, QR code authentication, FIDO2 security keys, and other Entra ID-supported sign-in methods. "Microsoft-provided SMS and voice authentication will retire starting February 1, 2027. Complete your migration before rollout begins to avoid interrupting users' sign-in experience," Microsoft said in a Microsoft 365 Message Center update on Tuesday.
