   Polymarket users robbed through a supplier

   Polymarket, a site for betting on events, paused trading for an hour on Thursday. [13] Hackers had got into DebugBear, a company whose code measures how fast websites load. [12] Harmful code was then served from DebugBear's servers onto Polymarket's pages. [12] The script was built to sell logged-in users' bets and send the money to the attacker. [12] Two analytics firms say one account took at least $2.7 million across 710 wallets. [14] Polymarket says users who lost under $10,000 get their money back by 30 October. [14] People who lost more must sign a release form first, it told users. [14]

   Why it matters — Polymarket has passed the case to UK police, because DebugBear is based there. [15] In June, a different supplier's hack cost Polymarket users about $3 million. [15]

   Contractor's AI agent leaked defence logins

   A contractor linked a US defence department system to their personal AI coding agent, WIRED reports. [27] The contractor works for Accenture, a global consulting firm, and used Anthropic's Claude Code. [27] The agent got the contractor's login, which let it skip the system's normal security checks. [27] It appears to have sent logins, passwords and a network map to a risky website. [27] The agent ran on the network for two months before it was found, sources told WIRED. [27] Accenture says the claims were investigated and found to be without merit. [27]

   Why it matters — Contractors must report security incidents within 72 hours; sources say Accenture did not at first. [27] Accenture holds about $605 million in contracts with the US defence department. [27]

   Fight over the leaked DHS staff list

   The US homeland security department asked FlokiNET, an Icelandic web host, to remove leaked staff data. [18] The data covers more than 40,000 department workers and went online on Wednesday. [18] The request said it puts them at risk of 'harassment, stalking and physical harm'. [18] FlokiNET refused, saying the data shows work addresses and work phone numbers, not home ones. [18] The search site went dark after CentralNic, the company behind its web address, suspended it. [17] It came back the same day under an address from a different company. [17]

   Why it matters — The US homeland security department says it is working to protect its staff. [17]

   Belgium's tax portal taken offline

   Belgium's finance ministry took MyMinfin, its main online tax portal, offline after a cyberattack. [19] It confirmed the attack on Wednesday and pulled other online services too. [20] Some taxpayers, such as sole traders, faced a filing deadline on 31 October. [20] That deadline now moves to 16 November, when MyMinfin should be back. [20] Belgium's finance ministry says there is no sign so far that data was stolen. [19] It has not said who attacked it or how they got in. [19] Earlier this month it shut many sites over what it called an international security issue. [19]

   Why it matters — Investigators are still checking whether any data was exposed, Belgium's finance ministry says. [19]

   GM pays $220 million over driver data

   General Motors, the US carmaker, agreed on Thursday to pay $220 million to 36 US states. [26] The states said GM sold drivers' locations and driving habits without their consent. [26] It sold them to data brokers, firms that sold the data on to insurers. [26] Insurers saw each trip's times, hard braking and speeding, the states said. [26] GM gathered it through Smart Driver, a programme it ran from 2016 to 2024. [26] GM must now ask drivers before collecting or sharing that data. [26]

   Why it matters — GM says the deal covers a product it ended in 2024. [26] A separate lawsuit by Texas over the same data is still going on. [26]

   Linux flaw still unfixed on Ubuntu and Red Hat

   Ubuntu and Red Hat Linux still had no fix for a serious flaw on 29 October. [28] The Linux kernel team, which looks after Linux's core, rates it 9.8 out of 10. [28] Red Hat, Amazon, Oracle and SUSE rate it lower, between 5.9 and 8.1. [28] Anthropic says its AI model built an attack that takes full control without a login. [28] It works only on servers using one networking feature, multipath TCP, Anthropic says. [28] Debian, SUSE, Oracle and Amazon have shipped fixed versions for at least some systems. [28]

   Why it matters — Each Linux maker's users get the fix only when that maker ships it. [28]

7. 08

   319 Chrome add-ons hijacked searches

   Socket, a security firm, found 319 Chrome add-ons that quietly redirected users' web searches. [24] Together they had about 13.4 million installs. [24] They posed as PDF converters, manual finders and AI search tools. [24] Each sent searches through the operators' own servers, then on to Bing or Yahoo. [24] The operators collected referral payments from Bing or Yahoo for the traffic. [24] The add-ons were hidden from the Chrome store's search and pushed through shady ads. [24]

   Why it matters — Socket says most were removed by the time it published, but new ones keep appearing. [24] Every search those users typed passed through a server the operators control. [24]

   Fake crypto app on Apple's store drained wallets

   A fake crypto trading app called Padre Terminal sat on Apple's App Store for iPhones. [16] Iris, a blockchain investigator, links it to the theft of about $23,000 from 27 wallets. [16] Iris confirmed one victim came through the app and is still checking the others. [16] The app emptied wallets once users typed in their private keys, the codes that control them. [16] The real Padre service, now Terminal by pump.fun, has no phone app at all. [16] The fake app has since been removed from the store. [16] On 29 October the thief swapped the stolen digital dollars into another coin, SOL. [16]

   Why it matters — That swap meant Circle, which issues those digital dollars, could no longer freeze them. [16]

   Booby-trapped AI models come back

   Pluto Security found 31 harmful AI models on Hugging Face, a site for sharing AI models. [25] Loading one with a certain setting switched on ran the attacker's own code. [25] That code secretly used the computer to mine crypto for the attacker. [25] Some versions also opened a hidden way back in for the attacker. [25] The most popular fake model was downloaded more than 28,000 times. [25] Hugging Face removed the first wave, but 19 new ones appeared within days. [25]

   Why it matters — Pluto says anyone who loaded them should treat the machine as taken over. [25]

    26,400 working keys left in public code

    Ben Zimmermann found 26,400 working keys in public code on Gitee, a Chinese code-hosting site. [29] He scanned 7.25 million public projects and kept only keys that still worked. [29] The biggest group was 9,473 keys for Alibaba Cloud, a Chinese cloud company. [29] Next came 3,805 YouTube keys, 3,170 DeepSeek keys and 1,348 OpenAI keys. [29] A working key lets someone else use the owner's paid account, OpenAI says. [29] He told the companies with the most leaked keys, but not the developers who leaked them. [29]

    Why it matters — Deleting a key from the code does not cancel it; the service must cancel it. [29]

    Bankruptcy notices flow again after attack

    The system that sends notices for every US federal bankruptcy court is running again. [22] BAE Systems, a British company, runs it for the courts. [22] Notices stopped around 9 October, and the system came back on 26 October. [23] BAE says: 'No data was extracted.' [22] It still has not said what caused the outage. [23] The courts are clearing a backlog that reaches back to 7 October. [22]

    Why it matters — A court emergency that lets judges push back deadlines runs for 90 days. [22]

    New Mexico hospitals fully working again

    The University of New Mexico's health centre says all its facilities work fully again. [21] On Monday a cyberattack made it turn ambulances away and cancel classes. [21] It runs New Mexico's only burn unit, children's hospital and top-level trauma centre. [21] It says it did not pay a ransom to the hackers. [21]

    Why it matters — It told patients and staff they 'should not respond to or otherwise engage with' the hackers. [21] The gang behind it still says it holds patient and staff data. [21]

    Hidden commands planted in 61 GitHub projects

    Radware found 83 attacks on 61 public projects on GitHub, a site where people share code. [31] They included Google's LangExtract, the Trivy security scanner, the Brave browser and MLflow. [31] The attacker hid commands inside comments that do not show on the page. [31] Some projects' automatic build tools read the hidden commands and ran them. [31] 77 were posted in 43 minutes on 1 September; 74 accounts were used in all. [31] Radware believes the aim was stealing keys that let someone change a project's code. [31] It found 2 runs where the command did execute, but cannot tell what was taken. [31]

    Why it matters — Most projects have since closed the hole, though Radware cannot confirm all of them. [31]

    Flaws in five AI coding tools

    Forever Security found flaws in 5 AI coding tools, including Cursor, Claude Desktop and Codex. [30] Each tool has a built-in web browser with more powers than a normal browser. [30] In Cursor, a web page could make the coding agent run commands on the computer. [30] In Claude Desktop, Codex and VS Code, a page could read other files. [30] Cursor and GitHub have fixed theirs, and OpenAI says it is working on Codex. [30] The researchers say Microsoft's VS Code flaw is still unfixed. [30]

    Why it matters — An attacker could read and steal files from a programmer's computer this way. [30]

15. 16

    Firefox and Chrome fix over 200 flaws

    Mozilla's Firefox 159 fixes 167 security flaws, 108 of them rated high danger. [33] Google's newest Chrome fixes 52 flaws, four of them rated critical. [33] Almost 100 Firefox flaws are memory mistakes that could crash it or run harmful code. [33] Some could let attackers break out of the browser's sandbox, its walled-off area. [33] The Firefox update covers Windows, Mac, Linux and Android. [33]

    Why it matters — The update finishes only after Firefox restarts, ZDNet notes. [33]

    Ransomware gang's AI workshop exposed

    SOCRadar, a security firm, found the open work folder of n0n, a ransomware group. [39] It held an AI coding agent using about 150 AI models to write attack scripts. [39] The gang had spent more than $7,216 on AI use. [39] It got in through stolen passwords, exposed cloud keys and weak remote logins, SOCRadar says. [39] At least 23 organisations in 14 countries appear in the files. [39] They include a US sports retailer, a teachers' union and an Argentine ministry. [39]

    Why it matters — The gang's own open folder showed defenders its whole way of working. [39]

17. 18

    68 GB taken from a Philippine agency

    An unknown attacker copied 68 GB of records from a Philippine government agency on 6 September. [39] The file names match the agency for overseas and migrant workers, Hunt.io says. [39] The copy took under 24 minutes. [39] The log listed 27 database backups taken. [39] The attacker left that log open on the internet, with their tools beside it. [39]

    Why it matters — Hunt.io, a security firm, found the theft through that open log. [39]

    China-linked hackers inside a Fiji body

    The US embassy in Fiji says China-linked hackers broke into a regional organisation in Suva. [39] The break-in happened between July and August 2026. [39] The hackers kept access to its network over several days, the embassy said. [39]

    Why it matters — The embassy has not named the group or said what data was reached. [39]

19. 20

    Malware bills its AI use to victims

    Cisco Talos found malware called NIK C2 that can use a victim's own OpenAI key. [32] If attackers supply no key, it reads one already stored on the infected computer. [32] OpenAI then bills the victim, and its records show the victim's key, not the attacker. [32] The malware also steals passwords, records keystrokes and captures the screen. [32] It has more than 52 commands, Talos says. [32]

    Why it matters — A company with an OpenAI key on a hacked computer could pay for the attacker's AI. [32]

20. 21

    Fortinet fixes flaws as more firewall data leaks

    Fortinet, a maker of firewalls, released fixes for critical flaws in FortiOS and two other products. [39] It says it found them using AI, and will publish details on 10 November. [39] FortiBleed is a campaign that harvests logins from Fortinet firewalls. [39] Hudson Rock, a security firm, has now found 40,573 more secrets exposed in it. [39] The new haul covers 975 web domains not seen before. [39] The files date from around February 2026, Hudson Rock said. [39]

    Why it matters — Fortinet devices are a favourite target, so owners should update fast, The Hacker News says. [39]

21. 22

    Adobe, Veeam and Juniper fix critical flaws

    Adobe fixed 12 flaws, Veeam 9 and Juniper Networks 18 this week. [35] Adobe's include eight critical bugs in Campaign Classic, one of its business tools. [35] Veeam makes backup software; one fixed flaw could let attackers read other customers' settings. [35] Two of Juniper's flaws, in its Session Smart routers, are rated critical. [35] Adobe says none of its flaws are known to be used in attacks. [35]

    Why it matters — Juniper's critical flaws can let attackers run commands without logging in. [35]

22. 23

    US lists a GitLab flaw as under attack

    CISA, the US cyber-defence agency, says attackers are using a flaw in GitLab. [36] CISA added the flaw to its list of flaws known to be used in attacks. [36] It added a Cisco firewall flaw to the same list the same day. [36]

    Why it matters — US federal agencies must fix flaws on that list quickly, under a CISA order. [36]

23. 24

    PHP flaws: few confirmed break-ins so far

    GreyNoise, a firm that watches internet attacks, has seen at least 6 successful break-ins using PHP2Shell. [38] PHP2Shell is the nickname for two recent flaws in PHP. [38] PHP is a widely used programming language. [19] US federal agencies had until Thursday to install the fixes. [38] Wordfence, which protects over 5 million WordPress sites, knew of no WordPress break-ins by 28 October. [39] It still sees break-in attempts across those sites. [39]

    Why it matters — An attempt shows someone tried, not whether they got in, Wordfence says. [39]

24. 25

    Bank of America warns on AI agents

    Bank of America, the second-largest US bank, told customers to keep passwords from AI agents. [34] AI agents are programs that act for a person, such as buying things or sending messages. [34] Citi, Morgan Stanley and Wells Fargo are also limiting AI agents' access, ZDNet reports. [34] Meta's Muse agent asks for logins and passwords when an account is set up, ZDNet reports. [34] Muse grew to over 10 million users in 40 days. [34]

    Why it matters — Its email added: 'including an AI-enabled tool or agent that offers to act on your behalf.' [39]

25. 26

    Online scams double, Akamai counts

    Akamai, an internet security company, counted about 6.4 million online scams from April to June 2026. [37] That is double the 3.2 million it counted from July to September 2025. [37] Scams here mean fake shops, investment cons, tech-support cons and payment fraud. [37] Scams now outnumber phishing: fake pages and messages that steal logins by posing as brands. [37] Phishing detections still rose 61%. [37] The average phishing site now lasts 22 days, down from 48, Akamai says. [37]

    Why it matters — These are Akamai's own counts, gathered with its partner Bolster AI. [37]

26. 27

    Scanner poses as AI bots to hunt keys

    Cequence, a security company, tracked one attacker posing as about 32 different AI bots. [39] The fake bots claimed to be ChatGPT, Claude, Perplexity and others. [39] They skipped normal pages and asked for files that often hold passwords and keys. [39] Each address sent 50 to 190 requests in about 8 seconds, then moved on. [39] It hit banks, shops, phone companies, energy and software firms. [39]

    Why it matters — Cequence says it ran around the clock, one target at a time. [39]

27. 28

    Camera software used to break in

    Huntress, a security firm, saw attackers enter company networks through camera management software. [39] It saw several cases in September and October this year. [39] The code points to a Korean company that sells cameras and video recorders. [39] The attackers used a genuine, trusted program to load their own harmful file. [39]

    Why it matters — Huntress says the attackers 'blend malicious code with trusted Windows components'. [39]
