Verborgene Tastenanschläge: Forensische Analyse eines Digispark HID-Geräts

Ein Digispark mag wie ein harmloses USB-Entwicklungsboard aussehen, lässt sich jedoch leicht in ein Gerät zur Tastenanschlag-Injektion verwandeln, das sich wie ein USB Rubber Ducky verhält. In diesem Artikel zeigen wir, wie ein solches Gerät eingerichtet, eingesetzt und forensisch analysiert werden kann, von der Ausführung der Payload auf einem Zielsystem bis hin zur Extraktion der Firmware aus dem ATtiny85-Mikrocontroller.

Keystrokes in Disguise: Forensic Analysis of a Digispark HID Device

A Digispark may look like a harmless USB development board, but it can easily be turned into a keystroke injection device that behaves like a USB Rubber Ducky. In this article, we show how such a device can be set up, used, and forensically analyzed, from payload execution on a target system to firmware extraction from the ATtiny85 microcontroller.

ConsentFix (a.k.a. AuthCodeFix): Detecting OAuth2 Authorization Code Phishing

ConsentFix (a.k.a.AuthCodeFix) is the latest variant of the fix-type phishing attacks, initially identified by Push Security. In this technique, the adversary tricks the victim into generating an OAuth authorization code that is part of a localhost URL, by signing in to the Azure CLI instance (or other vulnerable applications). Then, the victim is instructed to copy that URL and paste it into a phishing website, essentially handing over the authorization code to the adversary, who is now able to exchange it for an access token. Using the access token, the adversary gets access to the victim's Microsoft account.
