Hello, wonderful people. Taking a break is good, so I am taking a couple moments to write the #nakeddiefriday post of the week.

Today we have this interesting sample. Yes, it has certainly seen better days; been sitting in a queue for a real while now. This is again a smartcard chip without a name to it. I believe this to be fabbed by Samsung, and be rather old. The chip is built using poly-gate CMOS with 3 metal layers; later processes moved to a higher layer count.

#Newsboat und #Wallabag - Mehrere Smart Cards und unterschiedliche Betriebssystem verwenden

Newsboat kann ĂŒber die API Artikel direkt an Wallabag senden. Dort können die BeitrĂ€ge bequem und ĂŒbersichtlich verwaltet, mit Tags versehen und im Webbrowser oder der Wallabag-Apps auf allen EndgerĂ€ten gelesen werden.

In diesem Beitrag werden mehrere Clients und #Smartcards (#YubiKey und #Nitrokey) verwendet, um interessante Artikel an die zentrale Wallabag-Instanz senden.

Does anybody know what elementary file 2FE4 contain on SIM cards? It doesn't look like it is described in any standards I've looked at, and its contents varies widely across cards. Maybe boost for reach?

Hello! It's #nakeddiefriday today, and what I got for you is yet another smartcard chip. Please welcome an unnamed die marked K2D0A, fabbed by STMicro. This came from [REDACTED], used to [REDACTED]. The die oriented with power supply pads on top, so it's possible to figure out which die pads correspond to which module pads. Unusually enough, there are 6 pads bonded out; the function of the extra
pad is not known at this time-- certainly not VPP.

A short thread follows.

Zwei neue Forschungsprojekte der @Cyberagentur starten im Programm SCA4PQC. Sie zielen auf sichere Post-Quanten-Kryptographie – robust gegen physikalische Seitenkanalangriffe. Mit dabei: LEAP-CSP (Cloud & KI) und SPARTAQUS (Smartcards).

Ich habe eine kurze bebilderte Anleitung geschrieben wie man mit #Kleopatra und #GnuPG #OpenPGP SchlĂŒssel direkt auf #Smartcards wie #Yubikey #Token2 oder #Nitrokey erstellt

https://cryptomancer.de/posts/20251207-openpgp-smartcards/

GnuPG-SchlĂŒssel mit Kleopatra auf Smartcards (Yubikey/Token2/Nitrokey etc) erzeugen

In dieser Anleitung wird ein OpenPGP direkt auf einer OpenPGP-Smartcard erzeugt. D.h. der SchlĂŒssel existiert nur auf dieser Smartcard. Ein Backup existiert nicht und kann auch nicht erzeugt werden. Verliert man die Smartcard, ist auch der geheime SchlĂŒssel verloren! Eine Anleitung zur Offline-Generierung von SchlĂŒsseln und Upload auf mehrere Smardcards folgt noch. Erstellung von SchlĂŒsseln direkt auf der Smartcard, ohne Backup! Ein geeignetes SchlĂŒsselpaar erzeugen Tip Diese Schritte sind ein mal zur Erstellung eines neuen SchlĂŒssels durchzufĂŒhren

@wolf480pl yeah, because the idea is that #drivers should hook in the #USB stack and unless it's a Universal Class Driver should just passthrough to the driver / userspace application for ease of support.

who’s gonna tell the #Martians
why #Gazan lost kids weren’t on #cartons ?
slippery #WalkOns #grift for #argent
every time our #eyebrows arching
don’t let it touch the heartstrings
to get us to #SwipeAway as it hardens
#violent ardent khaki #sergeants
while we quake at #AlmondStalin
#GaryLineker ’s #PostPartum
pen over parchment starts to sharpen
I won’t make that bargain
I won’t beg that pardon
I be like “na man” gotta be barking
#PreciousIsEachFallenStarling
I’ll be the aveunt’s pesky #varmint
I’ll be #TestCase for their #retirement
I’ll be car-pooling up in the #parklands
opening the gates on #arkham
I’ll wipe out your margin
shave your #merkin
spice your #parkin
I’ll rehouse the martens
#TrainTheUrchins
spike your #garmin
I’ll be a #token doing a #slalom
round this #empire led by #Cartman
judged by duds like #MerrickGarland
none can thrive in this #environment
#censor tears of #Salah
lala to #Novara
if the bleeding party’s darker
#apathy #cicadas
while we eke they #parking
grasping for our farthing
all the #smartcards for the #outcasts marking
in this #awks #SharedDream hearken!
someone’s growing a fold: #Darkling
I don’t think we’ve time for #aksing
it’s got a bit beyond a #Marx ting
#DontSweat who’s inna room just barge in
tell them we need the #boats , we're not larking
#AllOfTheChildrenAreOurs when hurting
it’s part of our #dharma and we’re departing

#smartcards and #nuitka based project did not play nicely. No clue what went wrong, but I don't have free brain cycles to debug.

RFID cards could turn into a global security mess after discovery of hardware backdoor

Security researchers have discovered a backdoor in millions of RFID cards developed by Shanghai Fudan Microelectronics (FMSH). When properly exploited, this backdoor could be used to quickly clone contactless smart cards that regulate access to office buildings and hotel rooms worldwide.
