New research: “ Are You Really Muted?: A Privacy Analysis of Mute Buttons in Video Conferencing Apps “: Abstract: In the post-pandemic era, video conferencing apps (VCAs) have converted previously private spaces — bedrooms, living rooms, and kitchens — into semi-public extensions of the office. And for the most part, users have accepted these apps in their personal space, without much thought about the permission models that govern the use of their personal data during meetings. While access to a device’s video camera is carefully controlled, little has been done to ensure the same level of privacy for accessing the microphone. In this work, we ask the question: what happens to the microphone data when a user clicks the mute button in a VCA? We first conduct a user study to analyze users’ understanding of the permission model of the mute button. Then, using runtime binary analysis tools, we trace raw audio in many popular VCAs as it traverses the app from the audio driver to the net...

Interesting implementation mistake : The vulnerability, which Oracle patched on Tuesday , affects the company’s implementation of the Elliptic Curve Digital Signature Algorithm in Java versions 15 and above. ECDSA is an algorithm that uses the principles of elliptic curve cryptography to authenticate messages digitally. […] ECDSA signatures rely on a pseudo-random number, typically notated as K, that’s used to derive two additional numbers, R and S. To verify a signature as valid, a party must check the equation involving R and S, the signer’s public key, and a cryptographic hash of the message. When both sides of the equation are equal, the signature is valid. […] For the process to work correctly, neither R nor S can ever be a zero. That’s because one side of the equation is R, and the other is multiplied by R and a value from S. If the values are both 0, the verification check translates to 0 = 0 X (other values from the private key and hash), which will be true regardless o...

Beanstalk Farms is a decentralized finance project that has a majority stake governance system: basically people have proportiona votes based on the amount of currency they own. A clever hacker used a “flash loan” feature of another decentralized finance project to borrow enough of the currency to give himself a controlling stake, and then approved a $182 million transfer to his own wallet. It is insane to me that cryptocurrencies are still a thing. from Schneier on Security https://www.schneier.com/blog/archives/2022/04/clever-cryptocurrency-theft.html
