[en] Signal #messenger: "two practical attacks that break the integrity properties of #Signal in its advertised #threat model" - Patched

Paper #ETHZ

"... protocol for resolving identities based on usernames and on phone numbers introduced a #vulnerability that allows a malicious server to inject arbitrary messages into one-to-one conversations under specific circumstances"

"The second #attack is even more severe. It arises from Signal's Sealed Sender (SSS) feature, designed to allow sender identities to be hidden ... a combination of two errors in the #SSS implementation in #Android allows a #malicious server to #inject arbitrary messages into both one-to-one and group conversations."

[en] Tackle storage demands of anonymous cryptocurrencies

"This work tackles the ever-growing #storage demands of #anonymous cryptocurrencies. It introduces a new scheme that randomly partitions the fresh outputs of transactions into fixed-size bins. Subsequent transactions reference these outputs when they transfer the tokens further."

"The basic idea is that once a bin has been referenced as many times as its size, it can safely be pruned from the ledger. This preserves both #privacy and #security, but reduces the data that needs to be stored on the #distributed #ledger."

[en] MIT study: Negative Neural and Behavioral Consequences of LLM-Assisted Essay Writing

"Over four months, #LLM users consistently underperformed at #neural, #linguistic, and #behavioral levels."

"These results raise concerns about the long-term #educational implications of LLM reliance and underscore the need for deeper inquiry into #AI's role in learning."

[en] From Walls to Windows: Creating Transparency to Understand Filter Bubbles in Social Media

"... studying filter bubbles in social media ... has proven challenging, despite extensive #research in this area. In this work, we introduce SOAP (System for Observing and Analyzing Posts), a novel system designed to collect and analyze very large online platforms (VLOPs) data to study filter bubbles at scale."
