Chainalysis says attackers exposed usernames, password hashes and live tokens for all of its customers. "While the company locked Chainalysis accounts as a precaution after discovering that some customers' passwords had been exposed and asked users to reset their passwords before signing in again, it has now taken the login portal offline, together with Reactor and Data Solutions, the Know-Your-Transaction (KYT) user interface and API, and address screening products, after discovering further abnormal activity," reports BleepingComputer.

The company says it has no evidence that investigative data or blockchain attribution records were accessed or altered, but all users will be required to reset passwords and rotate API keys before regaining access. BleepingComputer reports: Chainalysis provides blockchain analysis tools to trace cryptocurrency transactions and investigate crimes such as fraud, ransomware, and money laundering. Its customer list includes law enforcement, government agencies, financial institutions, insurance companies, and cryptocurrency businesses worldwide. This follows the company's disclosure last Friday that attackers using AI tools accessed customers' names, email addresses, user IDs, and organizational role labels using what it described as "offensive agentic techniques."

While it initially said the impact was limited and the breach affected only non-sensitive identity metadata, later updates revealed that usernames and password hashes for all customers were exposed in an "on-path attack" (more commonly known as a Man-in-the-Middle or MITM attack). However, the company found no evidence that the attackers accessed investigative graph data or altered its blockchain attribution repositories. [...] To ensure threat actors don't access affected accounts, Chainalysis asked customers to provide trusted IP addresses so they can regain access to the login portal once it is brought back online and reset their credentials.

OpenAI says its new GPT-6 Cyber model helped an automated system identify 1,724 security flaws in the Linux kernel and exploit 948 of them to gain administrator-level access during testing, including at least 10 previously unknown techniques. Axios reports: During testing, the system identified 1,724 security flaws and found ways to use 948 of them to gain administrator-level access to Linux systems for about $1.2 million in API credits. At least 10 of the techniques the model used were previously unknown, according to OpenAI. Human researchers reviewed the Linux findings before reporting vulnerabilities and proposed fixes to maintainers. The model also uncovered 81 previously unknown, high-severity flaws in Mozilla's Firefox browser.

The FAA announced today that it is finally phasing out floppy disks from air traffic control systems at more than 400 facilities. Engadget reports: They'll be replaced by a more modern system called Enterprise -- Information Display System (E-IDS), which is comprised of a digital display for relaying status information, updates and other alerts to air traffic teams. The FAA plans to have E-IDS installed in 435 sites by the end of 2028; the first five locations to receive the upgrades are the Atlantic City International Airport, Nashville International Airport and Greater Rochester International Airport, as well as data processing hubs in Atlanta and Salt Lake City.

Joe_Dragon shares a report from TechCrunch: Applebee's has fixed a security flaw that allowed anyone to access the personal information of its registered customers, after a researcher found a password for an internal database inside Applebee's mobile app, TechCrunch has learned. The popular restaurant chain confirmed [last Thursday] that it had taken action to address the security issue to prevent any unauthorized access to its customer database. [...] The exposed database contained customer names, email addresses (including whether or not the customer verified their email), dates of birth, phone numbers, and ZIP codes. The data also included veteran status, the number of times customers had logged in, when their accounts were created, and the IP addresses of their most recent log-ins, which can be used to reveal the person's approximate location.

[...] When asked by TechCrunch, the spokesperson would not say if the company has server logs that it can review to determine whether anyone accessed the database, or if it has any logs at all. "Our investigation is ongoing, and we will take appropriate steps based on our findings," the company added. It's unclear how many customers were affected by the data exposure. [...] Applebee's had at least 8.5 million customers enrolled in its rewards program as of last year, though the company would not provide a number of how many customers had their personal information exposed by this security flaw.

A newly disclosed OpenSSH flaw dubbed "*sshole" can allow attackers to log in to password-disabled accounts on certain musl-based Linux systems simply by submitting a password longer than 256 bytes. "Apparently certain varieties of musl Linux (Alpine, OpenWrt, Buildroot, Yocto, etc.) have had this OpenSSH vulnerability for about a decade," writes longtime Slashdot reader AlteredEgg. "Upgrade now!" BleepingComputer reports: Security researcher Ozgun Kultekin, who discovered and released details on the vulnerability today, says the flaw has existed since 2016 and stems from how OpenSSH handles password verification errors on systems using the musl C library. Linux accounts can be configured to prevent password logins by replacing their password hash with an asterisk (*) in the /etc/shadow file. Because this is not a valid password hash, no password should allow access to those accounts. However, a patch introduced in OpenSSH in 2016 to fix a username enumeration vulnerability tracked as CVE-2016-6210 changed how OpenSSH handled accounts without usable password hashes.

To prevent attackers from identifying valid usernames through different response times, OpenSSH was modified to perform password hashing even when an account had no usable password hash, including accounts configured with * to block password logins. The problem is that the musl C library's crypt() function also returns * when password hashing fails, including when a submitted password exceeds its 256-byte limit. This means an attacker can submit an oversized password and cause OpenSSH to compare the returned * against the account's stored *, resulting in a successful login.

To be clear, the flaw does not allow attackers to bypass passwords on accounts with valid password hashes. [...] Admins who can't immediately install the update can mitigate the issue by turning off SSH password authentication with PasswordAuthentication no in their SSH server configuration and restarting SSH. Kultekin says admins can also check for signs of exploitation by examining SSH authentication logs for password-based logins for accounts that should not allow them.

Longtime Slashdot reader bbsguru shares a report from KrebsOnSecurity: Several staffers at the White House are using computers or mobile devices equipped with residential proxy services that render their internet address available for others to rent, security experts warned today. One of the proxy services is a Russian company whose founder's web hosting business was ground zero for cyberattacks against election systems in Arizona and Illinois in 2016. The security firm Layer3 Intel said it detected multiple residential proxy nodes beaconing out from the internet address network reserved for the Executive Office of the President (AS2650). Layer3 said the proxy activity was relatively persistent between October 5 to November 3, and that a review of the proxies available from AS2650 showed they exited from the White House network 236 times during that period.

The proxy tracking company Synthient said on Twitter/X that the activity it saw coming from AS2650 was related to multiple Windows 11 installations of a service called Infatica, a proxy program that is often integrated into "free" mobile and desktop applications. Infatica's founder Vladimir Fomenko is a Russian man whose hosting firm King Servers was home to six of the eight internet addresses used by Russia's state security services to compromise databases for election systems in Arizona and Illinois in 2016. [...] Layer3 Intel said the proxy exit nodes at the White House came from six internet addresses, on 26 of the 30 days, and that most of the activity happens in the evening, between 5 p.m. and midnight. Incredibly, Infatica was not the only proxy service that reportedly has been reselling access to White House internet addresses: Layer3 Intel said it found 28 separate residential proxy services were able to exit through this network. "This is public access," the Layer3 Intel team wrote. "Anybody can obtain it by signing up to a public residential proxy service, paying a few dollars and sending requests through it. We did not selectively target this network or try to make our probes exit from it. We caught this by chance, simply by requesting global rotating access through these services."

An anonymous reader quotes a report from Reuters: The refrigerators at three regional blood banks in France were hit by a cyberattack overnight between Sunday and Monday, at the same time hackers struck supermarkets from Sweden to Belgium. "Several regional facilities of the French Blood Establishment (EFS) were affected by a cybersecurity incident that impacted certain cold storage room monitoring and control systems," the health ministry said in a statement.

The incident had no impact on blood supplies, EFS spokesperson Charley Dubois said. "We have staff round the clock since blood can be needed at any time. They were warned about the problems by alerts and moved the blood to other refrigerators that were not connected," she said. [...] Investigations are under way into how the attack was carried out, what equipment may have been affected and when systems can safely return to service. The attack followed a similar incident in France last month when police said hackers seized control of cooling units at hundreds of supermarkets, causing fires and food losses.

Binance says hackers spent months infiltrating its systems through fake job interviews, a tampered developer tool and compromised internal AI tools before stealing $6.34 billion in crypto in the Oct. 29 attack. Co-CEO Richard Teng said Binance has replenished 98% of the affected assets, and that it is still in the process of purchasing outstanding, more illiquid assets. CNBC reports: Preparations for the attack began in June, when a Binance Wallet DevOps engineer downloaded a tampered Homebrew installation "to install a popular AI coding tool after searching for it on a search engine," according to a security report published by Binance Tuesday. It said it detected the suspicious activity, replaced the engineer's device and rotated credentials as a precaution, but that by then the employee's "role and his related colleagues on our wallet infrastructure team was exposed to the hacker."

[...] As of Tuesday Binance has rebuilt the affected wallet system and internal AI tool, replaced compromised devices, decommissioned credentials and tokens associated with the affected engineers and expanded security scans across employee devices, Teng told "Squawk on the Street."

"We're also getting an independent expert to review everything that we have done, and we'll keep strengthening our defenses as the investigation continues," Teng said. "We're working around the clock with law enforcement agencies and with industry partners to trace and freeze the stolen funds for that front."

A coalition of security firms working with Japan's National Police Agency has disrupted a botnet of more than 1.3 million Android devices across 200+ countries. "We assess with high confidence that the backdoor and botnet were intentionally developed, deployed, and operated for financial gain by Videostrong Technology," the Google Threat Intelligence Group (GTIG) said in a blog post. The Register reports: Videostrong Technology is a hardware manufacturer based in Shenzhen, China. It builds Android devices, including home TV boxes and projectors. According to Google, Videostrong deliberately embedded the XCPE backdoor in device firmware and sold access to criminal affiliates, allowing them to install additional malware modules on devices shipped to unsuspecting customers. When buyers connected these devices to their home networks, the preinstalled backdoor allowed operators to create proxy networks and hide malicious traffic using the customers' internet connections without their knowledge.

The firmware's pre-installed management agent purported to be a standard remote-management client, according to TrendAI. It pulled updates from a GitHub page, and connected to a Message Queuing Telemetry Transport (MQTT) server that gave the operator full remote control of each box, allowing them to install and remove apps, change settings, and push updates to the infected devices. Between June 3 and October 1, TrendAI documented more than 3.8 million distinct home and mobile IP addresses connected to the operation.

The coalition also disrupted the command-and-control domains used to manage the affiliate modules. "Because these affiliates each have diversified distribution channels for their modules beyond XCPE, we assess that taking down their C2 domains will sever access to at least 10 million additional compromised devices," according to GTIG. Google said it had since cut ties with Videostrong, and banned the OEM from making devices with preloaded Google apps.

An anonymous reader quotes a report from The Guardian: Supermarket chains in Sweden, Belgium and Luxembourg have said the temperatures of their refrigerators and freezers in dozens of stores rose overnight, prompting fears of a cyber-attack similar to one that caused millions of euros of food losses in France. Sweden's Coop chain told the daily Aftonbladet on Monday that six of its stores had been affected, while ICA said it was "aware that a limited number of stores were affected by an incident overnight which impacted their refrigeration and freezer systems".

The Dutch retailer Ahold Delhaize, which last month reported a cybersecurity incident to police in the Netherlands, said an "IT incident" had hit fridges and freezers in dozens of its supermarkets in Belgium and Luxembourg. A company spokesperson, Sarah De Meester, said the supermarket chain had established that temperatures in the cooling systems had increased, adding that the incident was being investigated. Belgium's Le Soir newspaper reported that dozens of stores and supermarkets were affected, including five Spar outlets, multiple Shop & Go convenience stores attached to Q8 service stations, and a number of smaller Proxy Delhaize minimarkets. "We started mobilizing technicians at 1am," Stephan Moelans, the chief executive of Sabcobel, which specialises in refrigeration system installations, told the paper. "We spent all night and morning disconnecting the affected installations from the grid."

The Washington Post reports: Tens of thousands of South Koreans had their financial data exposed online in recent weeks after at least nine major banks there suffered cyberattacks that suggested a dark future for online security. One man, a 26-year-old living in southern China, was allegedly behind the attacks, according to an investigation by cybersecurity company CrowdStrike. Traces left online and failure to secure his own systems allowed investigators to piece together the man's name, age, location and what he allegedly did. The clues revealed that the devastating assault on some of Asia's most sophisticated financial institutions was the work of an amateur. The attacks were launched with help from a few artificial intelligence chatbots, CrowdStrike found, before asking one to help sell the stolen data online and draft a fake résumé touting cybersecurity skills...

The hacker who broke into the South Korean banks had access to Anthropic's Claude, but because the U.S. firm's tools generally refuse to take illegal actions, free Chinese models were also used, including DeepSeek, CrowdStrike found. "The models are interchangeable," said Meyers, the CrowdStrike executive.
The Post calls it "part of a wave of AI-enabled hacking that is advancing across the world, triggering alarm inside national governments as well as multinational companies." "Basically any pedestrian, non-hacker can take these frameworks and start leveraging them to go after different targets," said Adam Meyers, senior vice president of counter adversary operations at CrowdStrike. The company has tracked an increase in the speed with which cyberattacks can move once inside a target's networks, as seasoned hackers and rank amateurs alike get a boost from AI tools. "Anyone can be a super-hacker now," Meyers said... Many cyber experts still expect the security reckoning to intensify as AI tools that can find and exploit software bugs become more widely distributed and understood.

[Last] Monday, The Post reported that cybersecurity researchers from the start-up Cathedral who set out to test Anthropic's security found that they could access internal messages and meeting transcripts. Cathedral reported its findings to Anthropic, which said it resolved the newly discovered problems... Security experts say it's unlikely that any hacker is forgoing the use of AI tools right now.
Even in America, critical infrastructure like energy and water companies need to be "immediately and comprehensively" tested for exploitable bugs, according to Snehal Antani, chief executive of cybersecurity company Horizon3. He tells the Post the government might need to fund that remediation, and even form "a public and private partnership to accelerate incident response."

SystemD creator Lennart Poettering left Red Hat for Microsoft in 2022, but 10 months ago left to co-found Amutable a company that aims to build cryptographically verified Linux systems that stay trusted over time.

It's FOSS calls it "a read-only, image-based system where every machine produces signed reports of its own state" — and signups are now open for a private preview: Before announcing this Linux-based implementation, Amutable had released two open source tools. tine, a Buck2-based build system that composes OS images; available under MPL-2.0, and Quarry, a TUF-based tool that distributes those images to machines; available under Apache-2.0. What Amutable Foundations brings to the table is a service where Amutable runs the images, update repositories, control plane and vulnerability fixes for organizations and individuals who operate their own systems.

No license has been stated for those company-run parts, and the preview announcement does not say how much of Foundations beyond tine and Quarry will be open source. Software and configuration both ship as signed images, and a machine boots only what is signed. Because there is no package manager and no SSH or interactive shell, a change means giving every machine in your fleet a new signed image.

Its images are reproducible, come with a software bill of materials (SBOM) and are built from pinned inputs of whichever distribution you pick, with tine being able to import packages from Fedora or CentOS Stream. Each machine sends a signed report that records what it booted, from the firmware and boot loader up to the kernel and OS, plus the configuration it runs... Amutable's control plane verifies reports from systemd-report, an experimental command in systemd 260 that the company helped build. It compares each one with the declared state and flags machines that deviate. A rollout only continues while machines can show they are in a good state...

Amutable is signup formlooking for teams that manage Linux fleets and need to show what state each machine is in. It expects to start bringing the first 'design partners,' as it calls them, on board over the coming weeks.

An anonymous reader quotes a report from Wired: Trading has resumed on Polymarket's flagship international platform after a hack that drained money from the wallets of some traders. A third-party vendor based in the United Kingdom was breached, not the prediction market's website itself. Law enforcement in the UK have been notified of the incident, the company said. Trading was initially paused while the company investigated for several hours.

On X, prominent traders complained that they had lost money; Blockchain analytics firm Bubblemaps reported that around 700 users appear affected, with approximately $2.7 million stolen. Polymarket declined to comment when WIRED asked how many traders were impacted by the breach and how much money was lost, but said it will refund impacted traders.

The hack did not impact users on Polymarket US, the company's newer platform for people within the United States. Polymarket runs two separate prediction markets; Polymarket US operates as a federally regulated financial exchange within the country, while the flagship Polymarket is a cryptocurrency-based platform that is banned in the United States and a number of other countries. This is not the first time that Polymarket traders have experienced losses like this. "A nearly identical vendor-compromise attack hit the platform in June, draining close to $3 million from at least 11 user wallets through the same kind of injected frontend script," reports StartupFortune.

Hours before Polymarket halted trading, more than $2 billion in cryptocurrency was drained from Binance wallets in just 40 minutes.

Longtime Slashdot reader schwit1 shares a report from TechCrunch: In an email blast to customers titled "Protecting your finances in the Al World," Bank of America urged customers to never share their username and password with another person or an outside service, "including an Al-enabled tool or agent that offers to act on your behalf." [...] A spokesperson for Bank of America confirmed the authenticity of the bank's email that was posted to social media. But heed the bank's warning, for if things go wrong, it's on you. Account agreements at most banks hold customers responsible for anyone they give their log-in to. "If you do share your credentials," its email reads, "keep in mind that you're responsible for activity resulting from that access."

A massive leak has exposed records tied to more than 41,000 DHS employees and contractors, including roughly 10,000 ICE personnel. The data, reportedly taken from DHS's Okta login system, reveals phone numbers, email and office addresses, reporting relationships, and permission groups associated with undercover operations, wiretapping and surveillance tools. Wired reports: In all, the leak provides a map of how DHS is organized and how it operates. The records, which span DHS itself as well as seven component agencies, including Immigration and Customs Enforcement and US Customs and Border Protection, were last updated on August 19, 2026.

The transparency nonprofit Distributed Denial of Secrets and cybersecurity researcher and journalist maia arson crimew previewed the data to WIRED, which they say they obtained from a group calling itself the Department of Peace. DDoSecrets published the archive, which it calls "Icepick," on Wednesday. In a press release, DDoSecrets says the data is from DHS's Okta login system. In a note with the files, the hackers wrote, "They have our information, so it's only fair that we have theirs." An Okta spokesperson tells WIRED that it is unaware of any breach of its systems. "We are aware of this report. Okta is secure, and we have no evidence our data or systems were compromised," the spokesperson says.
