The call for talks for CAW 2026 (a workshop affiliated with Eurocrypt) is out!
This year's motto is "cryptography under real-world constraints and threat models", but other applied cryptography is also very welcome.
All info is on: caw.cryptanalysis.fun.

Klimathotet/Svenska krisberedskapen

Steg 2
Två av tre tjänster inom förebyggande klimatarbete försvinner
Steg 3
Klimatrelaterade katastrofer blottar luckor i krisberedskapen
Steg 4
Klimatministern läxar upp länsstyrelserna
Steg 5
[inget händer]

Snabba klipp blir Europas undergång
Jonas Algers: Från folkhem till hustlarkapitalism
ABB:s robotikförsäljning till Japan är ett tecken på Sveriges och Europas industriella förtvining.
Där tänker man långsiktigt – här jagar man snabba klipp, skriver @jonasalgers.bsky.social.

Geostationary satellites are leaking critical data, transmitting sensitive communications in the clear. With just $800 of consumer hardware, researchers intercepted military, telecom, retail, and infrastructure traffic. satcom.sysnet.ucsd.edu/docs/dontloo...

Fattigdomen fördubblad i Sverige på tre år | Dagens Arena
Andelen fattiga i Sverige har fördubblats sedan 2021 och är nu nära 7 procent av befolkningen. 700 000 personer klarar inte att betala nödvändiga utgifter.
Påminnelse. År 2025 lever 700 000 människor i materiell och social fattigdom i Sverige. Det är en ökning med 120 000 på ett år. Bara sedan 2021 har andelen fattiga nästan fördubblats, från 3,5% till 6,6%. Ojämlikheten skenar

Ett screenshot med texten
”Min avsikt: Med denna inloggning kommer FinShark AB komma åt följande tjänster i 180 dagar:
- Titta på transaktionskonton och kortkoppladekontokopplade kort
- Initiera betalningsuppdrag från transaktionskonton”
Jag försökte bli månadsgivare till en organisation jag stödjer, men för att godkänna autogirot var jag tvungen att ge något som heter FinShark tillgång till mitt konto i 180 dagar!? Det känns ju helt bananas! Är det här verkligen det bästa vi kan åstadkomma 2025?

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

I really recommend reading the blog post though. It goes into detail on some of the engineering and security considerations that went into the design, as well as how the rollout is handled.

The triple ratchet extends the double ratchet with a second, sparse post-quantum ratchet called SPQR. SPQR is based on a chunked version of ML-KEM 768. The outputs from both are passed to a KDF to form a hybrid KEM.

Signal is really pushing the envelope with their new post-quantum secure triple ratchet. The protocol is formally verified using ProVerif, and the implementation uses hax to verify correctness and panic-freeness of the implementation. Really great work!

An image of the Mexican gulf, with the label ”Mexican gulf” followed by ”American gulf” in parenthesis.
In the EU (Sweden) we (and Google) are apparently still not wholly convinced.

I know it’s been said again and again, but what does it say about ChatControl that its backers keep explicitly *exempting* law enforcement and national security accounts from content scanning?

Man page for the less command, telling you that the flag LESSSECURE puts the less command in secure mode
TIL that setting LESSSECURE makes you more secure

The image shows two LibreOffice documents. A normal document to the left, and a malicious document to the right. The malicious document contains an additional, malicious word/document.xml file. The signature is checked against the original word/document.xml file, while the malicious word/document.xml file is displayed to the user.
Great paper on finding and exploiting parser differentials between ZIP parsers to bypass signature validation, malware detection, or VSCode extension ID validation.

There's a sick linenoise article by @there.is.no.aarch64.mov in @phrack.org 71 called "Learning An ISA By Force Of Will", where ixi goes from unknown binary blob, to manual instruction decoding, to figuring out control flow, and gives a critique of the RE'd ISA.
