"It's rough because, for those who are still doing this, the load is increasing," Tozny understands, cyber professionals are busy! Our technology is designed to optimize security posture while minimizing the overhead it takes to run it.

New: we proved it could be done. I used an AI replica of my voice to break into my bank account. The AI tricked the bank into thinking it was talking to me. Could access my balances, transactions, etc. Shatters the idea that voice biometrics are foolproof vice.com/en/article/dy7axa/h…

Models such as Stable Diffusion are trained on copyrighted, trademarked, private, and sensitive images.
Yet, our new paper shows that diffusion models memorize images from their training data and emit them at generation time.

"Given access to a synthetic dataset, a strategic adversary can infer, with high confidence, the presence of a target record in the original data."
Synthetic data have a lot of value, so this study is concerning and disappointing to see. Though perhaps not surprising.

In our latest article, Galois research engineer Sourya Dey discusses DLKoopman, an open-source software tool developed by Galois to model and predict the behavior of complex systems, from aeronautics to quantum mechanics to medical science and beyond. galois.com/blog/2023/01/dl-k…

I got into a discussion with @OrinKerr the other day about the recent NYT op-ed on Signal and whether “metadata-resistant communications” is good or bad for policing and if it should be opposed. And I guess I wanted to talk about how those arguments should be approached. 1/

As experts have long been pointing out: NFTs are a lie. The "thing" you think you are buying is just a URL. When the website goes down, your NFT points to nothing.
FTX-hosted NFTs break after website is redirected to a restructuring page
December 7, 2022

ALT FTX-hosted NFTs break after website is redirected to a restructuring page After FTX declared bankruptcy, the entire FTX.us domain was redirected to a page providing information on the bankruptcy proceedings. However, NFTs that had been minted on the FTX platform relied on metadata from an API at that domain, meaning that the NFTs are now pointing to broken links. Owners of these NFTs can still see that the NFT exists, but images no longer work—even when viewing the NFTs in their own wallets, or when listing them for sale on other platforms. Other projects that rely on the FTX NFT platform's API, such as the Coachella NFT project, also broke: the Coachella NFT platform shows 0 NFTs in existence. Those NFTs are still show up where they are listed on external NFT platforms, although the images and metadata are broken.

Looks like Apple is rolling out opt-in end to end encryption for iCloud backups. apple.com/newsroom/2022/12/a…

I can’t tell what’s going on internally, but it looks like Apple has gotten over these concerns sufficiently to (soon) enable full encryption for iCloud backups. This will require users to opt in, and it will include a “social backup” feature in case you lose your passcode. 6/

1. Signal (libaxolotl) uses GPL/AGPL.
2. Moxie goes on vacation.
3. Twitter abandons it’s encrypted DMs project.
4. Elon Musk can read your DMs.

A buddy who's interested in end-to-end encryption (E2EE) but hasn't done one of these projects in the very messy place which is the real world happened to ask me this morning about pitfalls which might not be obvious. So here's a partial list in the hopes that it's helpful. 🧵

In the interest of privacy, security, and clarity we’re beginning to phase out SMS support from the Android app. You’ll have several months to export your messages and either find a new app for SMS or tell your friends to download Signal.
