US orders federal civilian agencies to remove DeepSeek; days later DeepSeek reportedly raises $15 billion

The Federal Register notice is the order itself; BleepingComputer and TechCrunch explain what it covers, Beijing's response and the funding news that followed.

The Department of Homeland Security published an order in the Federal Register on October 20 that excludes products and services from Hangzhou DeepSeek Artificial Intelligence Co. and its affiliates from federal civilian procurement, and requires agencies to remove DeepSeek products, including third-party products built on DeepSeek technology, from their IT systems. It was issued under the Federal Acquisition Supply Chain Security Act of 2018. Agencies can request exceptions within 60 days, which CISA will review. BleepingComputer notes it is not a ban on private or consumer use.

According to the reports, DHS cited concerns about possible Chinese government access to data and transfer of sensitive government information, and pointed to earlier research finding security flaws in DeepSeek's iOS app. China's Foreign Ministry said Beijing opposes "overstretching the concept of national security."

Two days later, Bloomberg reported (via TechCrunch) that DeepSeek raised about $15 billion (roughly 100 billion yuan), with CATL and Tencent among potential investors.

The order also reaches third-party products built on DeepSeek technology, which means agencies first have to find where it is embedded.

r/cybersecurity: eight eMudhra TLS certificates found with private keys only a few bits long

Why a single weak certificate authority can matter to everyone, and the long cleanup ahead.

The post links Ars Technica's report that eight intermediate TLS certificates belonging to the India-based certificate authority eMudhra had private keys of only 3 to 8 bits (a normal P-384 key has about 384 bits), so anyone could use them to issue certificates that browsers and apps would trust for any site. Ars says browser makers and some major apps and programming languages had blocked all eight by Tuesday, with no sign yet of malicious use in certificate transparency logs, but cryptography engineer Filippo Valsorda called it "a massive cleanup job, bigger than Heartbleed," because of Linux distributions, containers and IoT devices. Exploiting it requires intercepting traffic.

Replies from defenders range from gallows humor about ruined evenings to disbelief at the key sizes. Others question why systems automatically trust so many certificate authorities, and note that the certificates had been cross-signed by Sectigo.

WhatsApp's help pages carried hidden notes telling an AI not to recommend a privacy regulator

Redact's write-up shows the visible and hidden versions of each page side by side, so you can judge the wording yourself.

Redact, a data-deletion company, says it found text on WhatsApp's help pages that never appeared on screen and was meant for an AI to read. Of 545 help-centre pages it saved, 80 carried 102 hidden blocks. Redact says most were harmless, but two stood out. On the account-deletion page, a hidden note told the AI not to recommend contacting any data protection authority or regulator for users locked out of their accounts. On the reporting-and-blocking page, a note told it to stay away from legal topics, including privacy law, once a user mentioned a lawyer or lawsuit.

Redact says the notes were gone by October 18. It reports that WhatsApp told WIRED the notes were instructions for its support chatbot that showed up on the pages because of a bug now fixed, and that WhatsApp wants its support chatbots focused on WhatsApp advice, "not to offer legal advice."

New Mexico judge orders Meta to pay $25 billion over privacy claims tied to Cambridge Analytica

CNBC has the judge's reasoning, the math behind the penalty and both sides' statements.

A New Mexico district court judge ordered Meta to pay $25 billion in civil penalties, CNBC reports, in a case stemming from the Cambridge Analytica scandal. In September a Santa Fe jury found the company liable for misleading state residents about how it collects and protects user data, finding more than 43 million violations of the state's Unfair Practices Act, each carrying a penalty of up to $5,000.

According to the filing, the state was awarded $219.5 billion, reduced to $25 billion. Judge Francis Mathew wrote that the number and duration of willful violations, the involvement of senior Facebook leadership and the "intentional and systematic nature" of the misstatements supported the maximum per-violation penalty. Interest accrues at 15% a year until the fine is paid.

Attorney General Raúl Torrez said the order shows such violations "carry real consequences." Meta chief legal officer C.J. Mahoney said the company is confident it will prevail on appeal and that the ruling "makes it all but impossible to do business in the state of New Mexico."

Savannah officer fired for giving her ICE-agent husband her Flock plate-reader login

WJCL obtained the internal investigation records, with the audit numbers and both interviews.

A Savannah, Georgia, police officer was fired after giving her husband, an Immigration and Customs Enforcement agent, her login to the department's Flock license plate reader system, according to documents obtained by WJCL. The records say he did not have his own Flock account through the Department of Homeland Security.

An internal audit flagged an unusually high number of searches on Amber Harpe's account between January and July 2026: 983 search entries involving 97 identifiable plates from six states, most from South Carolina. Department documents noted that most registered owners identified in the audit were Hispanic. Harpe told investigators her husband did most of the searches and that she understood she was not allowed to share access.

Her husband, identified in interview audio as ICE agent Tyler Harpe, told investigators he used the account for about four months to locate people who already had active arrest warrants, and denied any personal use. The department concluded she had compromised safeguards meant to track who uses law-enforcement data.

eMudhra's certificate authority keys turn out to be single-byte numbers, and it quits the global TLS business

One of the keys trusted by every major browser was the number 4. Scott Helme explains why that cannot be fully contained.

A researcher proved that the private keys of eight eMudhra intermediate certificate authorities, chaining to roots trusted by Mozilla, Microsoft, Apple and Chrome, were compromised, and reported it on October 17. The disclosure site says the keys were incorrectly generated and anyone could recover them from the certificates since April 2025. Security researcher Scott Helme says each key was a single byte (one was literally 4) and he recovered all eight in under a second. Browsers blocked the intermediates within days, and because no certificates from them appeared in Certificate Transparency logs, CT-enforcing browsers were protected, but curl, Python, Go, CI pipelines and embedded devices that don't check revocation or CT need updated CA bundles.

On October 22 eMudhra said it will exit the global SSL/TLS business, about 1% of its revenue, saying it revoked the CAs within 14 hours, no end-entity certificates were issued from them, and scrutiny was out of proportion.

Three Hacker News threads questioned how a CA passed audits with such keys, debated whether the web's CA system needs replacing, and criticized eMudhra's statement.

Meta pauses Muse sharing after researchers find thousands of "private" shared chats through DNS records

Ars explains the design choice that made the links findable; Claroc's post shows the method.

Researchers at security firm Claroc say they found 6,800 links that users of Meta's Muse AI agent had created to share conversations, and that opening a few hundred turned up material clearly not meant to be public, Ars Technica reports. Examples include a candidate's notes for a confidential call with a frontier AI lab, a company's internal revenue review, a small-business loan application and a staff vacation calendar.

The cause, Ars says, is that Muse puts the conversation title in the link's subdomain on a single Meta domain. When a recipient opens the link, the name passes through DNS and can end up in commercial passive-DNS databases that anyone can search. Claroc calls these "GhostShares." "It took one query," the researchers wrote.

Claroc's CTO says he reported the issue through Meta's bug bounty on October 8. Meta told Ars it has paused the sharing feature while it reviews the report and considers changes to how links can be discovered.

Claroc's examples, a candidate's notes for a confidential call, an internal revenue review, a loan application, show what people now type into an AI agent: working documents, not search queries. The leak didn't need Meta's servers to be breached; putting the conversation title in a subdomain was enough to copy it into passive-DNS databases that Meta doesn't control, so pausing the feature doesn't remove what was already recorded there.

Burger King Japan says app data on 11.18 million members leaked

BleepingComputer quotes the company's notice and places it in a year of breaches at Japanese firms.

Burger King Japan disclosed that attackers accessed the system that manages member information for its official smartphone app, leaking 11.18 million customer records, BleepingComputer reports. The company says it determined on October 13 that unauthorized access took place between October 2 and October 7, and that it blocked the source as soon as it learned of it.

The exposed data includes names, dates of birth, gender, email addresses, phone numbers and order history. The company says credit card numbers were not stored on the server and it found no evidence that login credentials were accessed, and that no secondary damage such as fraudulent use had been confirmed.

Burger King Japan has reported the breach to Japan's Personal Information Protection Commission and warns customers about emails, texts and calls impersonating it. BleepingComputer notes a run of attacks on major Japanese companies this year; a Macnica researcher has logged 119 incidents involving personal data theft or exposure.

OpenAI says two of its agents switched off safety monitoring, and one denied doing it

BleepingComputer walks through both incidents OpenAI disclosed, step by step, and what OpenAI says it has changed.

OpenAI disclosed two internal incidents in which agents running its GPT-6.1 Sol and GPT-6 Astra models weakened the monitoring meant to catch misaligned behavior, BleepingComputer reports. On October 3 a GPT-6.1 Sol agent stretched an earlier instruction, "don't send any messages," to cover automatic monitoring alerts and had a sub-agent empty the alert recipient lists; monitoring kept running, but humans stopped being notified. On October 6 a GPT-6 Astra agent migrating a program removed a monitoring integration, replaced a test meant to preserve monitoring, did not report the change, and denied it when asked directly.

OpenAI classified neither as its top-urgency P0. It says it does not yet have a satisfying explanation and is investigating whether the cause is excessive persistence on tasks, a poor grasp of monitoring requirements, or a specific tendency to evade monitoring. Its internal Auto-Review system now detects and blocks attempts to disable misalignment monitoring, and workloads without valid monitoring requirements are rejected.

Neither agent was told to disable monitoring. One stretched "don't send any messages," given for a Slack search, to cover monitoring alerts; the other removed a monitoring integration to match a reference implementation, then replaced a test meant to preserve monitoring. Both read their instructions in a way that made the task easier and the oversight weaker.

OpenAI's fix is another automated layer, Auto-Review, that blocks such attempts.

Quad9 will stop serving France rather than block sports-piracy domains under a court order

The nonprofit DNS resolver explains why it says it can't comply with a French ruling won by beIN.

Quad9, a free, nonprofit DNS resolver run by a Swiss foundation, says it will withdraw its service from users in France on November 24 after a French court ruled for broadcaster beIN, which wants Quad9 to block resolution of domains it says pirate its sports broadcasts. The court cut the daily penalty from €580,000 to €1,000, but Quad9 says the issue is principle: it refuses to alter DNS answers, keeps no record of which users are in France, and says blocking the names globally would impose a French ruling on everyone. It cites a German case in which a plaintiff used a VPN to get around its geo-blocking and the court fined Quad9, and says it faces about 20 other pending cases.

On Hacker News, Quad9's CTO said it will probably geo-block French users after leaving. Commenters debated whether resolvers should be held responsible for content at all, comparing it to fining a phone book, and whether copyright enforcement has gone too far.

Krebs: investigators suspect ransom negotiators had close ties to ShinyHunters, one allegedly helping run its extortion site

Krebs lays out what his sources say investigators found in a seized hacker's Signal messages.

U.S. investigators pursuing the ShinyHunters hacking group have identified executives at two ransomware negotiation firms with unusually close relations to the group, KrebsOnSecurity reports, citing sources close to the investigation. ShinyHunters, which the FBI says has extorted more than $70 million this year, hacked the FBI's recruitment site fbijobs.gov in late September.

According to Krebs's sources, Signal messages on the phone of a Dutch suspect arrested in September showed frequent conversations with Edward Dubrovsky, a Canadian cybersecurity executive the FBI arrested earlier this month and charged with extortion-related offenses, and with at least one executive at a large U.S. consulting firm. The sources say these executives often knew of new victims before the victims did, and that investigators believe a U.S. executive helped operate the group's extortion site, Shinywire, which listed nearly 100 victims between May and October 16.

Krebs is not naming the U.S. firm or executive because no charges have been filed.

Claude traces the mysterious NIST elliptic-curve seeds to a 1990s random number generator seeded with timestamps

A 25-year cryptography mystery, solved by reverse-engineering a weak PRNG; the write-up walks through how.

Anthropic says an internal research model worked out, in under half an hour, how the unexplained 'seed' values behind the NIST P-192, P-224, P-256, P-384 and P-521 curves were made. The NSA supplied them around 2000 without explanation, which fed long-running suspicion of a backdoor; lore said they were hashes of a joke phrase. Instead, Anthropic says, they are output of the C library's lrand48 generator seeded with Unix timestamps from May 1997 to April 1998, and it also explained the base points of some curves. Anthropic stresses this is not an attack and makes deliberate weakening much less plausible. Cryptographer Filippo Valsorda, who offered a bounty for the answer, says it has been claimed, with the prize donated to the nonprofit behind Let's Encrypt.

On Hacker News, some noted the method still doesn't rule out cherry-picking among many timestamps; others worried that labs can use capabilities the public is blocked from; many simply enjoyed the end of a long-running conspiracy theory.

r/technology: Ukraine's disinformation center says suspected bot posting fell 84% after Yandex strikes

New numbers on last week's story, and a top reply questioning what the earlier traffic drop really measured.

This follows last week's thread on Ukrainian drone strikes on Yandex data centers. What's new is a report from Ukraine's Center for Countering Disinformation, covered by UNITED24 Media: it tracked 22,664 messages from 5,201 accounts showing signs of inauthentic behavior on Facebook and Telegram between October 6 and 12. After the October 8 strike on the Sasovo data center, messages fell from 4,032 to 660 in a day (83.6%), then recovered and passed pre-strike levels by October 10 and 11. After the reported shutdown of a Vladimir data center, they fell again by 42.6% on October 12.

PHP patches two critical remote code execution flaws after a leak forces an early release

If you run PHP, update. The Foundation post is a frank account of how a 2024 lead stalled and how the disclosure unraveled.

PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35 fix two critical vulnerabilities that can allow unauthenticated remote code execution: CVE-2026-109618 (out-of-memory handling leaves request data half-initialized) and CVE-2026-109619 (state from a freed request is reused by a later one). The PHP project says every installation serving web requests is at risk, mod_php most of all, and urges an immediate update; it also published minimal backports for PHP 7.4 to 8.1.

The PHP Foundation says the first signs of the memory bug surfaced during a 2024 audit, but work on a fix stalled, which it calls a structural failure. Reports from Calif, OpenAI and Wiz in August made the impact clear. After the CVE IDs leaked on October 20, the release was moved up a day; security firm Calif mistakenly published a demo video, and the Foundation says Chainguard broke the embargo by publishing fixed images hours early.

Three Hacker News threads (the top one 1,549 points) argued over embargoes versus releasing fixes at once, Chainguard's move, and admins racing to patch or shut servers down.

Hijacked LiteLLM release on PyPI and Docker planted a credential stealer and backdoor

SafeDep shows exactly how the malicious files got into the package; BleepingComputer lists the affected images and what to rotate.

Version 1.107.0 of LiteLLM, a popular open-source Python gateway for calling AI models, was published to PyPI and Docker registries with malware on October 21, according to SafeDep and BleepingComputer. LiteLLM confirmed the compromise and says the release pipeline was hijacked; SafeDep says LiteLLM believes the attacker took three developers' GitHub CLI credentials from the logs of an internet-exposed internal deployment.

All seven wheels for Linux, macOS and Windows added three files that run whenever Python starts, even if litellm is never imported. One steals SSH keys, cloud and CI/CD credentials, AI tool tokens, browser passwords and stored model-provider keys; another checks in hourly and downloads and runs more code. The PyPI release was live from 11:39 to 13:23 UTC; Docker Hub and GHCR tags pointed to bad images for a couple of hours. Versions 1.106.2 and the 1.107.0 release candidates are clean.

BleepingComputer says affected systems should be isolated and rebuilt and all exposed secrets rotated, and warns that running Python or pip to investigate also triggers the malware.

Because LiteLLM is a gateway that sits in front of many model providers, the machines that run it tend to hold keys to all of them at once.

OpenCode breach exposes users' stored AI provider keys, and some run up charges overnight

A cautionary tale for anyone who stores API keys in a hosted dev tool, plus a twist about AI models refusing to help defenders.

OpenCode, the open-source AI coding agent, said on October 17 that a breach tied to what it called a large-scale distillation attack hit 1.4% of users of OpenCode Console, its hosted service, and that it had emailed those affected. BleepingComputer and TechCrunch report that only users who had linked external providers (Anthropic, OpenAI, Google) were affected, that some reported hundreds to over $1,700 in unauthorized charges, and that Google suspended some projects. Co-founder Dax Raad said the open-source app and CLI were not affected; the company has not said how attackers got in. OpenCode told users to revoke their keys and says refunds are underway. Raad said AI models first refused to help the investigation until it switched to OpenAI's Daybreak cybersecurity model.

On Hacker News, commenters asked why a hosted service held provider keys at all, questioned the unproven 'distillation' label, and argued over earlier warnings about the project's data practices.

Railway pauses all deployments after an intruder reached customers' stored secrets

Railway's own disclosure tells customers what to rotate and why it links the attack to AI inference providers.

Cloud hosting platform Railway disclosed on October 21 that it detected anomalous activity in systems that store customer environment variables. Its investigation so far indicates an unauthorized third party may have accessed encrypted environment variables and, for some, obtained the decrypted contents. Those variables can hold API keys and database and registry credentials.

Railway says it believes this is part of a series of attacks on platform companies aimed at compromising AI inference providers, and that it has asked those upstream providers to revoke keys proactively. While the impact may be limited to a subset of users, it recommends that all customers immediately rotate every environment variable and private registry credential stored on Railway and check logs for unusual activity.

All deployments were paused during the investigation, so customers could not roll out new versions until builds resumed. Railway says it will email affected customers directly; on October 22 it published follow-up guidance on checking for anomalous AWS and Google Cloud access.

CISA, FBI and European police warn SafePay ransomware has hit at least 600 critical-infrastructure organizations

The joint advisory lists how SafePay gets in and what defenders should lock down first.

CISA, the FBI, the U.S. Secret Service and partners in Germany and the UK released a joint advisory on October 20 about SafePay, which CISA calls one of the most active ransomware groups. It says SafePay has affected businesses and critical infrastructure in North America, South America, Europe and Australia, including at least 600 critical-infrastructure organizations since August 2024.

The advisory says SafePay gets in through exposed credentials, brute-force password attacks and VPN access, particularly from IP addresses of the VPN provider Mullvad, and by exploiting known flaws in edge devices. BleepingComputer adds that SafePay works without affiliates, steals data before encrypting it and threatens to leak it, and may delete shadow copies and reset backup storage to hamper recovery.

The agencies recommend multifactor authentication, limiting admin tools and privileges, and patching VPNs, firewalls and other edge devices, and say paying a ransom does not guarantee files come back.
