Schneier on Security · Chinese AI Submersible - Schneier on SecurityA Chinese company has developed an AI-piloted submersible that can reach speeds “similar to a destroyer or a US Navy torpedo,” dive “up to 60 metres underwater,” and “remain static for more than a month, like the stealth capabilities of a nuclear submarine.” In case you’re worried about the military applications of this, you can relax because the company says that the submersible is “designated for civilian use” and can “launch research rockets.” “Research rockets.” Sure. ...

Europa a Sinistra

Votiamo 5 SI ai referendum dell’8 e 9 giugno!
La CGIL ha puntato, con coraggio, su questa campagna referendaria.5 Referendum abrogativi che se accolti, possono migliorare concretamente la condizione dei lavoratori e lavoratrici italiane e straniere che possono diventare italiane, per il bene loro e dell'Italia.Per arrivare a questa decisione ci è voluto un dibattito profondo e travagliato.

Schneier on Security · Fake Student Fraud in Community Colleges - Schneier on SecurityReporting on the rise of fake students enrolling in community college courses: The bots’ goal is to bilk state and federal financial aid money by enrolling in classes, and remaining enrolled in them, long enough for aid disbursements to go out. They often accomplish this by submitting AI-generated work. And because community colleges accept all applicants, they’ve been almost exclusively impacted by the fraud. The article talks about the rise of this type of fraud, the difficulty of detecting it, and how it upends quite a bit of the class structure and learning community...

Another Move in the Deepfake Creation/Detection Arms Race

Schneier on Security · Another Move in the Deepfake Creation/Detection Arms Race - Schneier on SecurityDeepfakes are now mimicking heartbeats In a nutshell Recent research reveals that high-quality deepfakes unintentionally retain the heartbeat patterns from their source videos, undermining traditional detection methods that relied on detecting subtle skin color changes linked to heartbeats. The assumption that deepfakes lack physiological signals, such as heart rate, is no longer valid. This challenges many existing detection tools, which may need significant redesigns to keep up with the evolving technology. To effectively identify high-quality deepfakes, researchers suggest shifting focus from just detecting heart rate signals to analyzing how blood flow is distributed across different facial regions, providing a more accurate detection strategy...

Privacy for Agentic AI

Sooner or later, it’s going to happen. AI systems will start acting as agents, doing things on our behalf with some degree of autonomy. I think it’s worth thinking about the security of that now, while its still a nascent idea.

Schneier on Security · Privacy for Agentic AI - Schneier on SecuritySooner or later, it’s going to happen. AI systems will start acting as agents, doing things on our behalf with some degree of autonomy. I think it’s worth thinking about the security of that now, while its still a nascent idea. In 2019, I joined Inrupt, a company that is commercializing Tim Berners-Lee’s open protocol for distributed data ownership. We are working on a digital wallet that can make use of AI in this way. (We used to call it an “active wallet.” Now we’re calling it an “agentic wallet.”) I talked about this a bit at the RSA Conference...

Schneier on Security · NCSC Guidance on "Advanced Cryptography" - Schneier on SecurityThe UK’s National Cyber Security Centre just released its white paper on “Advanced Cryptography,” which it defines as “cryptographic techniques for processing encrypted data, providing enhanced functionality over and above that provided by traditional cryptography.” It includes things like homomorphic encryption, attribute-based encryption, zero-knowledge proofs, and secure multiparty computation. It’s full of good advice. I especially appreciate this warning: When deciding whether to use Advanced Cryptography, start with a clear articulation of the problem, and use that to guide the development of an appropriate solution. That is, you should not start with an Advanced Cryptography technique, and then attempt to fit the functionality it provides to the problem. ...

Schneier on Security · WhatsApp Case Against NSO Group Progressing - Schneier on SecurityMeta is suing NSO Group, basically claiming that the latter hacks WhatsApp and not just WhatsApp users. We have a procedural ruling: Under the order, NSO Group is prohibited from presenting evidence about its customers’ identities, implying the targeted WhatsApp users are suspected or actual criminals, or alleging that WhatsApp had insufficient security protections. […] In making her ruling, Northern District of California Judge Phyllis Hamilton said NSO Group undercut its arguments to use evidence about its customers with contradictory statements...

Schneier on Security · Applying Security Engineering to Prompt Injection Security - Schneier on SecurityThis seems like an important advance in LLM security against prompt injection: Google DeepMind has unveiled CaMeL (CApabilities for MachinE Learning), a new approach to stopping prompt-injection attacks that abandons the failed strategy of having AI models police themselves. Instead, CaMeL treats language models as fundamentally untrusted components within a secure software framework, creating clear boundaries between user commands and potentially malicious content. […] To understand CaMeL, you need to understand that prompt injections happen when AI systems can’t distinguish between legitimate user commands and malicious instructions hidden in content they’re processing...
