attack to decrypt and exfiltrate pgp or s/mime encrypted email is pretty hilarious.

Intercept an encrypted email and modify the email to add an HTML image URL directed to your malicious domain. Leave the image tag open (without closed quotes) and paste in the encrypted email and then close the image tag. Most clients will decrypt the text and query the malicious domain looking for an image matching the decrypted text.

This is why we encrypt and authenticate kids.

Apparently declaring to be dead, just because your business model requires it, does not make it so.

Some things are only born posthumously.

Presenting Cryptopals Set 8 challenge 6: KEY RECOVERY ON BIASED ECDSA NONCES. toadstyle.org/cryptopals/76f2e

Every DSA signature needs a random nonce, but not every DSA signature truly has one. With even a _bias_ in the nonce, a little linear algebra recovers keys.

roses are red
violets are blue
in surveillance capitalism
poem reads you

and shows you ads
for flower shops
and tracks your clicks
and never stops

it cares not about
if privacy's harmed
the money is green
when people are farmed

twitter is cyan
facebook is blue
your friends are the product
and so are you

Ohai!

I am toot. You click star, click boostybutton, author find out you exist. Might check you out.

Me bait, you fish.

Honest question for :

How practical is real-time voice synthesis (i.e. to reliably mimic a known target's voice and make it say what you want in a real conversation)? Assuming access to a large sample set (say a Skype scale dataset ;p), it seems like a much easier problem than real-time video fakes.

Anyway, it seems like there is an interesting class of exploits for such tech (from bypassing "your voice is your password" systems to social engineering).

I may do a patent search later.

Most importantly, stop putting institutional events on Facebook, stop using it at universities, stop making participation in Facebook mandatory through your institutional, organization, and activist roles. You can be online, and social, and connected without supporting Facebook.

“In a new project, the RSA and DeepMind are creating space for citizens to consider trade-offs in the use of AI” (thersa.org/discover/publicatio)

Here’s the letter I sent the RSA, both as a fellow and as someone who has presented an RSA talk on the subject, on how their partnership with Google/DeepMind/Alphabet, Inc. and this framing legitimises the false dichotomy at the heart of #SurveillanceCapitalism that there is a necessary tradeoff between modern technology and #privacy. mastodon.ar.al/media/DLpOYZB7I
