Two keys for all eventualities - Nitrokey (Part1)
1. increased safety requirements
The protection of digital identity is more important today than ever. Stolen online accounts can cause considerable damage if they are stolen and left in the wrong hands. At the same time, the number of data breaches is rising steadily - hardly a week goes by without at least one database of stolen accounts (user name and password) appearing somewhere on the Internet. In the worst case, the provider concerned did not protect the user passwords used or only inadequately protected them with a (cryptographic) hash function that was considered insecure.
Too often secret information falls into the wrong hands and the checking system cannot recognize whether Hildegard Mรผller is actually Hildegard Mรผller or whether her account data is being misused by a third party. A remedy against account misuse is to check additional properties or information via two-factor authentication (2FA), which is also controlled by so-called security tokens.
Security tokens or USB security sticks (Security Keys), however, offer other functions in addition to the 2FA that can contribute to increasing (personal) security. Among other things, the private key for e-mail or hard disk encryption can be securely stored on the stick. Such and other application scenarios are presented in the article series "Nitrokey" using the Nitrokey as an example.
2nd Nitrokey
Nitrokey is an open-source USB stick that enables secure encryption and signing of data, among other things. Depending on the Nitrokey version, such a USB stick supports different application scenarios:
๐๐ผ S/MIME email and disk encryption (X.509, PKCS#11)
๐๐ผ OpenPGP/GnuPG Email Encryption
๐๐ผ Login or authentication via two-factor authentication
๐๐ผ One-Time-Password (English)
๐๐ผ Universal Second Factor (U2F) via FIDO-Standard
๐๐ผ Integrated password manager
๐๐ผ Encrypted storage space on the USB stick (+Hidden Volumes)
๐๐ผ Possibility to update the firmware
The Nitrokey variants also differed in the supported cryptosystems, key lengths and Co..:
๐๐ผ RSA key lengths from 1024 - 4096 bits
๐๐ผ ECC key length from 192 - 521 bit
๐๐ผ Number of key pairs that can be stored on the stick 3 / 38
๐๐ผ Elliptical curve algorithms NIST P, Brainpool, Curve25519 and SECG/Koblitz
โ ๏ธ Advice:
Only the Nitrokey Start controls the elliptical curve Curve25519, which is one of the SaveCurves - the only curve where the choice of curve is completely transparent and therefore back doors can practically be excluded.

GnuPG Key Generation and Smartcard Transfer - Nitrokey (Part 1 and 2)
1. key material
Depending on the version, a Nitrokey supports different application scenarios. In this article of the article series "Nitrokey" I describe the commissioning of a Nitrokey under GNU/Linux and the following GnuPG key generation. An (RSA) key pair is a basic requirement for the two application scenarios OpenPGP/GnuPG e-mail encryption and OpenSSH public key authentication.
The procedure described for creating a (RSA) key pair and then transferring it to the smart card of the Nitrokey should also be transferable to other security tokens such as the YubiKey.

Beyond the Horizon: Traveling the World on Camaro Dragonโs USB Flash Drives - Check Point Research โ June 2023
#CamaroDragon #USB #Flashdrive #MustangPanda #LuminousMoth #espionage #malware #China #Asia
In early 2023, the Check Point Incident Response Team (CPIRT) team investigated a malware incident at a European healthcare institution involving a set of tools mentioned in the Avast report in late 2022. The incident was attributed to Camaro Dragon, a Chinese-based espionage threat actor whose activities overlap with activities tracked by different researchers as Mustang Panda and LuminousMoth, whose focus is primarily on Southeast Asian countries and their close peers.#CamaroDragon #USB #Flashdrive #MustangPanda #LuminousMoth #espionage #malware #China #Asia

The Flipper One: Hacking Gadget is Becoming a Pocket Linux PC | Mobile Hacker
The Flipper Zero was never really about โhackingโ other peopleโs devices; its true value was helping owners understand how secure their own devices actually are. It allowed enthusiasts to find weak spots and think like a hacker to understand how an attacker might exploit or misuse common tech, like #RFID cards, rolling codes, replay attack, bad #USB, or remote controls.
But while the Flipper Zero is a fantastic starting point for learning #cybersecurity, it has its limits. To do more advanced work, you often have to connect to extra hardware for things like Wi-Fi or stronger radio. This is why the Flipper One is such a massive leap โ it isnโt just a sequel; itโs appears to be a full-blown pocket Linux computer.
