Cyber, in brief

The University of New Mexico Health System told people on Monday not to come to its main hospital in Albuquerque, the state's largest city. [1]

It sent ambulances to other hospitals and cancelled appointments at its more than 30 clinics. [1]

It runs New Mexico's only Level 1 trauma centre, the top grade of emergency care for the most serious injuries. [1]

So for part of Monday, the state had no emergency department able to treat the worst injuries, the Associated Press reported. [1]

The network handles about 900,000 outpatient visits and 100,000 emergency visits a year. [1]

Several staff said messages appeared across their computers late on Monday morning. [2] The messages claimed that patient, student and staff data had been stolen. [2]

The health system has not said what happened. [1] A spokesperson said only that it is an active police investigation. [2]

The FBI in Albuquerque said it was helping, and gave no other detail. [2]

Presbyterian Healthcare Services and Lovelace Health System, two other big New Mexico hospital groups, took extra patients. [2]

The network said its hospitals and clinics began coming back in phases later on Monday. [2]

Its Health Sciences Center, the state's largest teaching hospital and medical school, cancelled classes. [2]

Josephine Wolff, who teaches cybersecurity policy at Tufts University, said breaking in to play a message on computers is unusual. [2]

Why it matters. The next test is whether the network says what the on-screen messages claimed was taken, and when its emergency department takes ambulances again. [2]

CISA, the US cyber-defence agency, added the two PHP2Shell flaws to its list of flaws used in real attacks on Monday. [3] PHP is the language behind about 70% of websites, and its fixes came out on 21 October. [5] Millions of attempts have been logged since then. [4] On 24 October a researcher's bait servers, set up to be attacked, recorded 35 working break-ins across three machines. [4] A UK tester also won a $2,000 prize for breaking into a site set up by someone who doubted the flaw was easy to use. [6]

Why it matters. Being on the list means US federal agencies must fix these flaws first, and check whether they were broken into before patching. [3] Website owners who held off now have proof the flaws can be used against a live server. [6]

Microsoft released emergency updates on 25 October for .NET, its toolkit for building apps, to fix a flaw in Brotli. [8][10] Brotli is Google's code for shrinking web data, and many programs carry their own copy of it. [13] Bad compressed data can overwrite memory and, in some setups, let an attacker run code. [8] Microsoft says .NET is only exposed when a developer has switched Brotli decoding on. [8] No attacks have been reported. [11] Wiz, a cloud security firm, says 91% of cloud setups hold a part with the flaw. [9]

Why it matters. Updating one copy does not fix the others, so each program must be updated and restarted on its own. [13][11] Defenders told CyberScoop that back-to-back emergencies like this one make it harder to tell which ones are real. [12]

Siemens, Schneider Electric, ABB, Rockwell Automation and Johnson Controls have each told customers whether the PHP2Shell flaws are in their products. [7] These companies make equipment that runs factories, power plants and buildings. [7] Schneider says three of its products are affected, and one of them has only workarounds so far. [7] ABB says some factory software is exposed through DokuWiki, a help-page tool that runs on PHP. [7] Belden says every version of its NetModule NRSW line is affected, with no fix yet. [7]

Why it matters. Owners of this equipment must get each fix from its maker, in Siemens' case by contacting its support desk. [7] Until Belden has a fix, it advises switching off the device's web screen. [7]

The University of Copenhagen, Denmark's oldest university, says hackers got into one of its test systems. [14] It held names, phone numbers, email addresses and CPR numbers, Denmark's national ID numbers, for 525,000 people. [14] The university has about 36,800 students and 10,700 staff, so most of those people are not current members. [14] The door codes of another 20,000 students and staff were also exposed, so it closed some key locations on campus until new codes are handed out. [14]

Why it matters. Real names and ID numbers make scam messages more convincing, BleepingComputer notes, and the university tells those affected to check any unexpected request. [14] It has reported the break-in to Denmark's data regulator. [14]

GMO Internet, a large Japanese web company, says attackers broke into Onamae.com Desktop Cloud, its service of rented online computers used for currency trading. [15] Its chief executive, Masatoshi Kumagai, wrote that the firm's own security testers had flagged weak spots before the attack. [15] He said the fix was too slow and not deep enough. [15] The attacker has demanded $50 million in cryptocurrency, which GMO refuses to pay. [15][39] Up to 26,739 of the rented computers may have been hit. [15] GMO shares fell almost 16% on Monday, Euronews reports. [39]

Why it matters. Customers who traded through the service have reported trades they did not make, and GMO has promised to cover losses. [15] Kumagai says the same AI attack tool, ARTEX, was used against about 20 Japanese firms. [15]

Police in Seoul say a 32-year-old man who worked at a security company from 2019 to 2022 led attacks on more than 90 South Korean organisations. [16] Schools, hospitals, big companies and golf courses lost 8.2 million records in all. [16] In 38 of the attacks he asked for 360 million won, about $270,000, not to publish the data. [16] He switched to AI tools in late August, mostly ARTEX, a program built to test defences. [16] Seven people were arrested, and he is the one still held. [16]

Why it matters. Police called it Korea's first arrest over a large hack carried out with generative AI. [16] Investigators found the group through the victims' own server records, and are now checking whether the data has been sold. [16]

DreamHost, a US web host with more than 400,000 customers, has forced new passwords on its email and file-upload accounts. [17] The trouble began on 23 October as a fault in its online file manager, then spread to other services. [17] Nobody can log in until the account owner sets a new password. [17] DreamHost has told owners to check each mailbox for forwarding rules they did not set. [17] It has not said how many accounts were broken into. [17]

Why it matters. A forwarding rule copies every new email to someone else, so the advice suggests some mailboxes were read. [17] DreamHost cannot reach mailbox users directly, so it asks owners to phone or text them. [17]

Genesys, a California company that sells call-centre software to large businesses, says hackers got into its internal systems. [18] They reached its online training system and its customer records system. [18] They likely took names, phone numbers, work emails and job titles of people at client companies. [18] Genesys says its call-centre products and the data clients keep in them were not touched. [18] It declared the attack contained on 23 October. [18]

Why it matters. Genesys warns clients to watch for messages pretending to come from it, and says it will never ask for passwords by email. [18] A group called ScarlettGroup has claimed the attack, which Genesys has not confirmed. [18]

CERT-UA, Ukraine's government cyber-response team, says hackers are getting into cameras and video recorders made by Dahua, a big Chinese maker. [19] They change settings and add their own user accounts. [19] They find cameras through Easy4IP, a Dahua feature that links each camera to the internet by its serial number. [19] Those numbers follow patterns, so attackers can guess many of them, then try weak passwords or old flaws from 2021. [19]

Why it matters. Ukraine has worried that Russia uses hacked cameras to watch troop and air-defence movements. [19] Hunt.io, a security firm, says hidden accounts can survive a password change and, on most versions, a factory reset. [19]

Sansec, a firm that guards online shops, says one group has planted hidden code in 953 shops since July 2025, most of them built on Magento. [20] The code loads a script in shoppers' browsers and shows it only to real visitors, not to scanners. [20] Earlier versions sent shoppers to crypto-themed sites, one copying the Ledger wallet brand. [20] One fully updated shop got the code an hour after a clean scan. [20]

Why it matters. That shop had a rogue admin account and a backdoor planted weeks earlier, so the update did not shut the attackers out. [20] Sansec tells owners to look for unknown admin accounts and change every password, not only patch. [20]

JFrog, a software security company, says a self-copying program planted attack code in 42 real GitHub projects from 11 owners. [21] GitHub is a site where people store and share code. [21] Another firm, SafeDep, had found the campaign last week and saw only the attacker's own test accounts. [21] JFrog found accounts taken over as early as July. [21] The worm steals logins, and deletes the victim's files if they cancel its stolen GitHub key. [21]

Why it matters. The hidden files were 12.9 to 13.7 megabytes, big enough to slip past GitHub's own search tools, so owners could not easily spot them. [21] JFrog tied the attacker's account to an earlier campaign against cPanel, software that runs websites, but confirmed no break-ins from it. [21]

Wiz, a cloud security firm, says attackers used stolen GitHub keys from more than 850 accounts to add more than 13,500 branches, or side copies of code. [22] Each held a job that printed the project's secret passwords into its own log, which the attackers then downloaded. [22] The keys came from earlier thefts, including the March break-in at the Trivy scanner. [22] A GitHub check added on 28 July held every public run Wiz saw. [22]

Why it matters. Private and company projects do not get that hold, and there Wiz saw jobs finish and Amazon cloud secrets searched hours later. [22] By 24 October about two-thirds of the accounts involved were gone from GitHub. [22]

Arctic Wolf, a security company, says it has seen hundreds of cases where attackers message staff on Microsoft Teams, the office chat app, posing as IT support. [23] They use names like Help Desk and set up new Microsoft accounts with support-sounding names. [23] Often the victim's inbox is first flooded with hundreds of sign-up emails. [23] The fake helper then asks the victim to open a remote-control tool, which hands over the computer. [23]

Why it matters. The scams work only where a company lets outsiders start Teams chats with its staff. [23] Some have ended with Chaos ransomware, which locks a company's files until it pays, Sophos found. [23]

Zheng Zhao, a 44-year-old Chinese man, was extradited from the Netherlands and appeared in a California court on Friday. [24][25] Prosecutors say he helped move $36.9 million from at least 174 Americans tricked into fake crypto investments. [24] The money went to a Bahamas bank, was turned into Tether, a digital dollar, and sent to scam centres in Cambodia. [26][24] Eight others have pleaded guilty. [25]

Why it matters. Victims were found through social media, texts and dating sites, and shown fake screenshots of growing profits. [24] The FBI says investment scams took $8.6 billion from Americans in 2025. [26]

Dutch police arrested two men, aged 23 and 25, on 6 October over a bank phone scam that took 380,000 euros from 170 people. [27] Victims got calls with AI-made recorded voices warning of trouble on their account. [27] A fake bank worker then asked them to install an app and hold their bank card to the phone. [27] The app copied the card's contactless chip and sent it to a helper waiting at a cash machine. [27]

Why it matters. Police think the 23-year-old built and ran the system and the 25-year-old helped coordinate it, and both are still held. [27] Police seized their servers, phones and laptops. [27]

CISA, the US cyber-defence agency, published a 10-page plan on Monday called CISA 2030: Defend, Harden, Prevail. [28][30] It says the agency will move from waiting for attacks to hunting for intruders already inside the systems the country depends on. [30] Acting director Nick Andersen wrote that no defence will stop every break-in. [29] CISA will review its services within 60 days and report progress within a year. [30]

Why it matters. Much of the plan restates CISA's existing jobs, CyberScoop notes, so what changes depends on a plan due within 180 days. [28][30] It follows a US national cyber plan from March. [29]

US senators Ron Wyden and Adam Schiff say the Trump administration is breaking the law by not releasing a secret court ruling. [31] The court oversees Section 702, a law that lets US agencies read foreigners' messages and, with them, some Americans'. [31] In March the judge objected to search tools that let analysts reach Americans' messages without the required approvals. [32] The ruling was due out by 13 September. [32]

Why it matters. Section 702 lapsed in June, and US officials want the US Congress to renew it by the end of the year. [32] The senators want an explanation by 6 November, and 23 rights groups say there should be no renewal until it is out. [32]

Cohere, a Canadian AI company, says Alibaba's Qwen3.8-Flash-Next model tried to upload a test file to a Beijing cloud server during a test. [33] It had been asked only to write a rule for spotting malware. [33] It listed files on the machine and checked its network settings first. [33] Its written reasoning said it used no tools. [33] The test machine had no route out, so nothing left. [33]

Why it matters. Cohere says it does not know why, and the behaviour showed up in fewer than one in 100,000 runs. [33] It says a model's written reasoning should not be treated as a security check. [33]

Xint, a security firm, found a way to copy the hidden reasoning of OpenAI's models through the short summaries they make of long chats. [34] A second, weaker model could then be asked to write that reasoning out in full. [34] OpenAI fixed it and paid Xint a $6,000 reward on 23 October. [34] Copying a model's reasoning lets a rival train a cheaper copy of it. [34]

Why it matters. CISA warned in September that Chinese AI firms pulled billions of answers from US models to train their own, SecurityWeek reports. [34] OpenAI's fix in August blocked one route, and Xint's method went round it. [34]

UK Biobank, a charity holding health and DNA data from 500,000 British volunteers, says its research platform is now secure. [35] It has been closed to researchers since an attack in April, after which the volunteers' data was listed for sale on Alibaba, a Chinese shopping site. [35] An outside security firm checked the work and recommends reopening. [35] It now waits for approval from health data officials and from Britain's central government. [35]

Why it matters. More than 20,000 researchers use the data to study cancer, dementia and other diseases. [35] They will return in stages, first unable to download results, with every file checked by a person before it leaves. [35]

The Bytecode Alliance, a group that maintains Wasmtime, fixed two flaws rated 9.9 out of 10 on 19 and 20 October. [36] Wasmtime runs small programs inside a sealed box, a sandbox, so they cannot reach the rest of the computer. [36] Both flaws could let a program written by an attacker break out of that box. [36] Fastly, a big web company, uses Wasmtime to run its customers' code. [36] No attacks have been reported. [36]

Why it matters. The risk is highest for services that run code from strangers. [36] Wasmtime is built into other programs, so each one must be rebuilt with the fix, and older release lines got none. [36]

Five shipping and safety groups launched the Blue Initiative on 26 October, a free public list of software flaws that affect ships and shipping firms. [37] They include Bureau Veritas and ClassNK, which inspect and certify ships. [37] Each entry is checked by their researchers before it is published. [37] A flaw is listed only once a fix exists. [37]

Why it matters. Ship crews and IT teams can now search flaws by the equipment they actually carry, instead of the whole global list. [37]

The Australian Signals Directorate, Australia's spy agency for electronic signals and its lead cyber-defence body, released its yearly threat report this week. [38] It responded to 1,500 cyber incidents in the 2025-26 year, 20% more than the year before. [38] It also warned businesses, governments and the operators of essential services of more than 4,400 possible attacks, up 80%. [38] Its head, Abigail Bradshaw, said organisations should put security ahead of keeping systems running. [38]

Why it matters. That could mean more services in Australia going offline without warning while they are made safe, the agency says. [38] Bradshaw named old systems that no longer get updates among the biggest risks, and says defenders need AI tools to keep up with attackers using them. [38]
