matrix-sdk-base: Denial of service due to custom `m.room.join_rules` events

The matrix-sdk-base crate is unable to handle responses that include custom m.room.joinrules values due to a serialization bug. This can be exploited to cause a denial-of-service condition, if a user is invited to a room with non-standard join rules, the crate's sync process will stall, preventin...

Primitive Vector Cipher(PVC): A Hybrid Encryption Scheme Based on the Vector Computational Diffie-Hellman (V-CDH) Problem

This work introduces the Primitive Vector Cipher PVC, a novel hybrid encryption scheme integrating matrix-based cryptography with advanced Diffie-Hellman key exchange. PVC's security is grounded on the established hardness of the Vector Computational Diffie- Hellman V-CDH problem. The two-layered...

Matrix Push C2 abuses browser notifications to deliver phishing and malware

Cybercriminals are using browser push notifications to deliver malware and phishing attacks. Researchers at BlackFog described how a new command-and-control platform, called Matrix Push C2, uses browser push notifications to reach potential victims. When we warned back in 2019 that browser push...
