Do you have a subject that you are skilled and passionate about, enough to teach others? We’re looking for you to train students during SAINTCON 2026 this October!

The latest Proxmark3 release is called BREAKMEIFYOUCAN!

Not a random name.

That is the actual 3DES factory default key NXP burned into every MIFARE Ultralight C they shipped since 2008.

Somebody finally broke it properly.

The paper drops the keyspace from 2^112 down to 2^28.

Counterfeit cards fall in under 60 seconds from a single card interaction. The tooling is merged: https://t.co/2CYKrRdv22

@HackingDave I've loved 1Password since it was a baby. Paid for many versions. I miss LAN and iCloud sync, and the v8 app sucks. So after 7yrs of sub'ing. The price hike finally pushed me to do it, cancelled the family plan. We are apple captive, so moved to native apps. (passwords and notes)

@newsobserver Umm, you are posting this like 3 days too late. This is old useless news.

[Josh aka Zevlag @Zevlag]

@1o57 @defcon You have brought much joy and magic to my life. I really appreciate the wonderful influence.

[SAINTCON @SAINTCON]

@DEFCONNextGen @defcon hey @bradanlane, I DM'ed you, but it probably got lost. Is the presentation you did on these ciphers posted somewhere? My kids missed it but would love to work through it with their tubes.

If you're at Mandalay Bay today for #blackhat2025 and you have a standard c13 trapezoid power cord I could borrow or buy for one of my employees please shoot me a DM

@grok @1o57 @defcon Hey @grok what about this page and letter. https://t.co/9uZObp4YWq

[Tib3rius @0xTib3rius]

Folks, I'm asking for a huge favor. We have just over a month until DEF CON, and we need more survey answers for Feet Feud (Hacker Family Feud).

If you aren't planning on playing, please complete this short survey: https://t.co/daFofBeEPk

Also share it regardless in your social groups! Ty! 🫶

[Josh aka Zevlag @Zevlag]

hey @SwimTopia, I'm hearing that `heroku ps:restart -a app_name` is working now for some apps. Might be worth a try.

[OffSec @offsectraining]

Attention @kalilinux users! In the coming day(s), apt update is going to fail for pretty much everyone.

The reason? We had to roll a new signing key for the Kali repository. You need to download and install the new key manually: https://t.co/Lrx05NhcOx

[Josh aka Zevlag @Zevlag]

@gematsu I will not be purchasing any game key cards. They have only SLIGHTLY more value than Code-In-Box, in that you can resell a key-card. But no long term preservation value.

[Josh aka Zevlag @Zevlag]

@d1dymu5 @SAINTCON @JackRhysider This made me so happy! It was fun to hear.

[SAINTCON @SAINTCON]
