Google is dramatically shortening its deadline readiness for the arrival of Q Day, the point at which existing quantum computers can break public-key cryptography algorithms that secure decades’ worth of secrets belonging to militaries, banks, governments, and nearly every individual on earth.

Has anyone compiled the privacy policies of various LLM platforms, ideally in a comprehensive way? OpenAI said today that private health data and conversations shared by ChatGPT Health won't be used for training purposes. Does this mean OpenAI won't sell it either or give it to law enforcement when presented with a warrant? What about other AI chat services.
I'm looking for responses from experienced privacy professionals or advocates with empirical data. Please, no responses airing cynicism or grievances about AI privacy in general, no matter how valid.

I could really benefit from experts' analysis of this WSJ article reporting that China-backed hackers used Anthropic’s Claude to automate 80% to 90% of a September hacking campaign targeting corporations and governments.
There aren't a lot of specifics, but among those provided:
> The eﬀort focused on dozens of targets and involved a level of automation that Anthropic’s cybersecurity investigators had not previously seen.
> In this instance 80% to 90% of the attack was automated, with humans only intervening in a handful of decision points.
> The hackers conducted their attacks “literally with the click of a button, and then with minimal human interaction."
> Anthropic disrupted the campaign and blocked the hackers’ accounts, but not before as many as four intrusions were successful.
> In one case, the hackers
> directed Claude tools to query internal databases and extract data independently.
> “The human was only involved in a few critical chokepoints, saying,
> doesn’t look right, Claude, are you sure?’”
> ‘Yes, continue,
> ’ ‘Don’t continue,
> ’ ‘Thank you for this information,
> ’ ‘Oh, that
> Stitching together hacking tasks into nearly autonomous attacks is a new step in a growing trend of automation that is giving hackers
> additional scale and speed.
We've seen so many exaggerated accounts of AI-assisted hacks. Is this another one? Are there reasons to take this report more seriously? Any other thoughts?

I mean, just listen to him talk:
> Hackers aren’t just sitting in dark rooms typing away anymore. With AI, they can launch faster, smarter attacks that slip past traditional security systems. AI can be trained to find weaknesses in seconds, or even disguise itself to look like a human user, making it very hard to spot.
> In this sort of attack, AI can do the heavy lifting that used to take hackers weeks. It can scan for weaknesses across huge systems in minutes, and once it finds a way in, it can copy normal user behavior so it doesn’t raise any alarms. That makes it far easier for criminals to slip through the cracks without being noticed.
> That’s why this airport attack is so concerning. It shows how quickly the rules of cybersecurity are changing. If hackers are using AI to get in, we need AI detectors on the other side to keep them out.”

People working on post-quantum-proofing vulnerable encryption protocols (and curious onlookers) can find lots of value in this new post from Cloudflare. It discusses the herculean engineering challenges of revamping anonymous credentials that will be broken by a quantum computer. There's a growing need for this kind of privacy (for instance to make digital drivers licenses privacy preserving), which allows individuals to prove specific facts, like they have had a drivers license for more than 3 years, without divulging personal information like their birthday or place of birth. The long and short of of the challeng is that engineers can't simply drop quantum-resistant algorithms into AC protocols that currently use vulnerable ones. Instead, engineers will need to collaborate with standards bodies that build entirely new protocols, largely from scratch. The post goes on to name a few of the most promising approaches.

AMD, Intel and Nvidia have poured untold resources into building on-chip trusted execution environments. These enclaves use encryption to protect data and execution from being viewed or modified. The companies proudly declare that these TEEs will protect data and code even when the OS kernel has been thoroughly compromised. The chipmakers are considerably less vocal about an exclusion that physical attacks, which are becoming increasingly cheap and easy, aren't covered by the threat model These physical attacks use off the shelf equipment and only intermediate admin skills to completely break all TEEs made from these three chipmakers.
This shifting Security landscape leaves me asking a bunch of questions. What's the true value of a TEE going forward?. Can governments ever get subpoena rulings ordering a host provider to run this attack on their own infrastructure? Why do the companies market their TEEs so heavily for edge servers when one of the top edge-server threats is
physical attacks?
People say, "well yes. just run the server in Amazon or another top tier cloud provider and you'll be reasonably safe." The thing is, TEEs can only guarantee to a relying party that the server on the other end isn't infected and couldn't give up data even even if it was. There's no way for the relying party to know if the service is in Amazon or in an attackers's basement. So once again aren't we back to just trusting the cloud, which is precisely the problem TEEs were supposed to solve?

> The affected US‑EAST‑1 is AWS’s oldest and most heavily used hub. Regional concentration means even global apps often anchor identity, state or metadata flows there. When a regional dependency fails as was the case in this event, impacts propagate worldwide because many “global” stacks route through Virginia at some point.
> Modern apps chain together managed services like storage, queues, and serverless functions. If DNS cannot reliably resolve a critical endpoint (for example, the DynamoDB API involved here), errors cascade through upstream APIs and cause visible failures in apps users do not associate with AWS. That is precisely what Downdetector recorded across Snapchat, Roblox, Signal, Ring, HMRC, and others.

As the wave of authoritarianism has crested, I've been challenging myself and others to ween ourselves off of centralized platforms that leak our private data (through breaches or voluntarily) and deplatform us for any reason or no reason, leaving us high and dry with no warning. You know this is awful when labor unions, civil rights groups and other groups under threat continue to trust Slack, Gmail, Xitter and the rest now of the broligarch-owned gatekeepers more than ever.
Some of you (and in some cases I) have responded with criticism of those still using these platforms. Many of you say unions should use decentralized alternatives such as Zulip, PGP on top of Slack, Mattermost, Matrix. Besides victim blaming, this response is misguided because it expects groups divert resources from their core missions to making immature and hard-to-use platforms work inside their organization.
All of this reminds me of the struggles we had with our dependence on unencrypted email in the 2000s and early 2010s. Back then, the only alternative was PGP, which was unusable for 50% or more of email senders. Then @npub1rkw…5q62 came along and solved most of the sticking points, almost overnight.
The lesson: decentralized, privacy-preserving platforms don't happen by accident. And they can't be cobbled together in beta form. They require funding and smart engineering that prioritizes usability as much as security.
I'm still not sure how we ween ourselves off of centralized platforms, but I think the success of Signal may serve as a useful model. Maybe we don't try to replace all platforms at once, Maybe for now we focus on finding an alternative to, say, Slack and use the momentum of that to tackle other platforms afterward.
I obviously don't have answers yet. I don't think anyone does yet. But it's important we start asking questions and stop blaming non-technologists who just want a platform that works.

Now that Marc Benioff, owner of Slack and Salesforce, has confirmed he sides with authoritarianism, it's more incumbent on us than ever to move off central platforms, which can dump communications we presumed were private or cut us off for any reason or no reason at all.

My story from Monday is here:
https://arstechnica.com/security/2025/07/no-phishers-are-not-bypassing-fido-mfa-at-least-not-yet-heres-why/
In short, the attack as originally described simply would not work against a FIDO2-compliant authentication system. Whatever system the researchers analyzed used a non-FIDO2 fallback in the event the user was unable to provide FIDO2-MFA. Calling this a bypass is like saying a door lock is insecure because an intruder could enter through a window. Lots of publications continue even now to say this was a bypass. It wasn't.

The company that reported (incorrectly) finding a way to bypass FIDO2-based MFA says it's "collaborating with the FIDO Alliance to review the attack." It goes on to say: "We are working together to review our findings and will publish a follow-up as soon as possible." So far no one outside the company (and possibly inside) has been able to reproduce the attack.
FIDO2 is the world's greatest hope yet in battling credential phishing. It's such a shame that this research got published before the findings could be confirmed.

Coming shortly. Researchers say they've uncovered an in-the-wild phishing operation that "effectively bypasses any protections that a FIDO key grants." As I will explain, this isn't the case. The research misunderstands what's occurring in the attacks. More to follow.

So, send an email or DM that even passes through a Windows machine with Recall turned on and it's screenshotted, swept into OCR, processed by Copilot and stashed away in perpetuity. Recall reminds me a lot of the backdoor the FBI wanted Apple to build. The FBI said it would be safe because only the FBI would have access to it. Apple rightly pointed out that no, something that powerful would inevitably get hacked and abused in ways no one could control. Now, Microsoft is trying to say that the guardrails it has put on Recall will curb any unintended consequences and we're supposed to take that at face value?

People in comments keep saying, oh well, time to move to Linux, as if that somehow insulates them. They forget that even then every interaction their Linux box has with a Windows 11 installation will STILL be compiled into a database that can be abused.

No, I won't be going to RSA. In fact, I encourage everyone else to stay away. It's not fair to penalize people overseas for not traveling to the US because they don't want to jeopardize their safety. Besides, RSA is a really crappy conference with nearly zilch news value.

I don't want to sound naive, but I'm still trying to understand all the criticism over Trump imposing "reciprocal tariffs." If reciprocal tariffs are so bad, isn't it at least as bad that countries are imposing tariffs on the US in the first place? Sorry if this question sounds dumb. I spent 15 minutes looking online and still don't get it.

Here's the latest on XiaoFeng Wang, the a distinguished computer scientist who was summarily fired on Friday from his tenured position at Indiana University, where he had spent 20 years racking up accolades for his research in cryptography, privacy and cybersecurity. It comes from Alexander Tanford, president of the Bloomington chapter of the AAUP, the union representing IU professors, and colleagues of Wang's.
In February, an anonymous person filed a complaint alleging research misconduct against Wang. "The charge seemed trivial -- that he had failed to properly disclose who was principal investigator on a grant application and had not fully listed all his co-authors on an article," Tanford told me.
On March 13 or 14, IU temporarily suspended Wang, banned him from his office and denied access to his computer, research and data while the investigation continued. This is permitted under IU's research misconduct policy. The reasons, though, aren't publicly known.
On March 28, Provost Rahul Shrivastav informed Wang he was being terminated immediately. Shrivastav provided no reason (he mentioned Wang taking a job at a university in Singapore, but this is permitted and not grounds for dismissal). What's more, policy ACA-52, approved by the IU Board of Trustees, prohibits summarily firing a tenured professor.
Also on March 28, homes that Wang owns in Bloomington and Carmel, Indiana, were raided by the FBI. The FBI says the raids were court approved, but so far no one has seen a warrant. The US Attorney's Office for the Southern District of Indiana will neither confirm nor deny an investigation.
Indiana University has steadfastly refused to provide any reason for the termination or its failure to follow its own policy. Students and fellow faculty remain in the dark. His PhD students are frantically scrambling to find new advisors. One such student learned of Wang's firing only a few weeks before his PhD defense.
I reached out to Wang's attorneys 24 hours ago, and still haven't heard back.
We really need answers here. IU is tarnishing its reputation for academic independence. The lack of transparency here, both by IU and the FBI, truly sucks.

Can anyone help me help a friend recover his compromised Facebook account? He's not sure how it got hijacked, but someone is using it to reach out to people, make a friend request, and then ask them out on dates. He's an investigative reporter, so it's not clear if this is a targeted attack attempting to meddle with confidential sources or an opportunistic one doing something like pig butchering. In any event, the compromised account poses a threat to Facebook users. My friend has tried recovering his account by sending FB a scan of his driver license, but the recovery link he gets gives him an error when he clicks on it. Does anyone reading this work in security at FB, or know someone who does? I (and my friend) would be so grateful for any help. Please DM me, preferably by Signal (DanArs.82) or here on Mastodon.

I just came here to ask you why these vulnerabilities are rated so critical if they can't be remotely exploited. Looks like you partially answered my question, but can you say more, please? Isn't it pretty much always game over when a threat actor has unauthorized access to a VM connected to your network? What's the scenario you're envisioning that makes these CVEs such a threat?

Elmo critics: don't gloat too much about the recent declines in Tesla stock. Shares of this company have always been volatile, so a 32% drop since the beginning of the year says little. Share prices as of today are still 24% higher than 6 months ago, 44% higher than this time last year, and more than 5-fold higher over 5 years. Shares could surge again. It's way too early to declare any sort of victory or comeuppance.

Can we devote some time to discussing Slack? As in, why are we all sending our every thought to a centralized server that can be hacked, and can can train AI with them? And why is Slack allowed to store transcripts but I can't?
My union uses Slack for organizing. How crazy is it that an organization in the cross hairs of a dangerous and emboldened government would do this? With everything going on right now, I'd love to be more active in the union, but must I really give up so much to this opaque platform?
Is anyone else struggling with these concerns? Do you know of viable Slack alternatives? Are there any hacks that make Slack less of a privacy invasion or make LLM training harder? Are there at least ways for me to save sessions the way I can with IRC? How do I resist Slack and not lose touch with groups that still use it?

It looks like the "major" AMD vulnerability that @npub1525…3vrv reported had leaked has now been disclosed.
The vulnerability, with a 7.2 severity rating, allows hackers to bypass Secure Encrypted Virtualization—a protection that provides the cryptographic means for certifying that a VM hasn’t been compromised by anyone who may have had access to the physical machine running the vulnerable AMD chip. The patch comes in the form of microcode that presumably will be provided by the device OEM.

So now that Trump has retaken the White House and begun his irreversible campaign to dismantle democracy, all the Trump haters who couldn't bring themselves to organize around and vote for Harris want those of us who did to go on strike and take other drastic measures to resist. Seems like it would have been vastly better for these folks to exercise their power to keep Trump from winning and simply resist the Harris policies they opposed once she came into power. Even now, these folks voice no regrets, but they still think those of us who did actively support Harris should give up the paychecks our families depend on to take a stand against a catastrophe that easily could have been averted.

So many responses from people trying to find reasons to hold onto their payment cards. Fine, go ahead. Have your purchases, contacts and whereabouts permanently stored and tracked. Just don't lecture anyone about the dangers of unencrypted comms or website tracking.

privacy is another good reason for paying with cash. What's the point of using encrypted comms or ad blockers or taking other privacy-preserving measures and then buying everything with a payment card? Payment cards allow data brokers to track every purchase you make, every business you visit and when. When you split a check with someone else, it lets them know who your friends and coworkers are. The amount of privacy lost using payment cards is astounding.

If you're choosing locally owned businesses for your coffee, groceries or other things, kudos for supporting alternatives to corporate-owned outlets. A reminder that paying with cash allows them to keep the full proceeds rather than sharing them with moneygrubbing banks and payment processors.
