The Weakest Link

Wie man mit einem langweiligen Newsletter einen Google oder Microsoft Account übernimmt

Florian Schweitzer
Ein Klick auf einen "Unsubscribe"-Link in einem Newsletter reicht oft aus, damit ein Angreifer eine Rufumleitung bei einer Zielperson einrichten kann. Damit lassen sich etwa die Passwörter von mit der Rufnummer verknüpften Google- oder Microsoft-Accounts zurücksetzen.

Mobilfunkbetreiber sind weiterhin in vielen Fällen das schwächste Glied einer Sicherheitskette. Dieser Vortrag behandelt mehrere Cross Site Request Forgery (CSRF) Schwachstellen in Webapplikationen von Mobilfunkanbietern, die es ermöglichen, Rufumleitungen einzurichten. In Österreich waren im Jahr 2020 etwa 40% der Nutzer*innen von derartigen Schwachstellen betroffen.

Ransomware is a type of malware that encrypts the files of infected hosts and demands payment, often in a cryptocurrency such as Bitcoin. In this talk, we present a measurement framework that we used to perform a large-scale, two-year, end-to-end measurement of ransomware payments, victims and operators.

On November 13., Nintendo launched its newest retro console, the Nintendo Game and Watch - but by then it was already hacked! In contrast to the other Nintendo classic consoles (NES & SNES), Nintendo upped their game this time: A locked processor, AES-CTR encrypted flash & co. made it significantly harder to hack it, but in the end it was still hacked - one day before release. This talk walks through the whole process of opening it up, exploiting the firmware up to bringing homebrew to a new ...

After the first unsuccessful deployment of voting machines in Germany about ten years ago, elements of electronic voting have reached elections again. Although there is now still a paper-trail, more and more essential steps, such as counting the votes, are moved into electronic systems. This change in the ballot-counting procedure took place mostly unnoticed by the public. We are two very concerned election workers who present our first-hand experience in this talk. We show that the current ...

How secure is the interface between baseband chips and iOS? While this interface should protect against escalations from the baseband into operating system components, its implementation is full of bugs. Fuzzing this interface is not only relevant to security, but also results in various funny effects, since the iPhone looses information about its identity and location, and eventually ends up in a state with a few thousand unread SMS that can no longer be deleted.

The EU has been pushing for apps that support end-to-end encrypted messaging to contain an upload filter, which will scrutinise material for prohibited content before it's encrypted. This is the latest in a long line of attempts to maintain government access to data despite cryptography. In this talk, I will try to put them in context of the last two crypto wars and assess the costs their efforts have imposed on our economies. I'll finally ask what strategic direction democratic governments ...
