Apple's M1 chip has a vulnerability that can't be fixed without a silicon revision, according to developer Hector Martin. The flaw allows for covert channels that enable two malicious apps to talk to ...
Covert channels are clandestine communication paths that exploit legitimate network protocols or system functionalities to transfer information in violation of established security policies. They are ...
A transfer of information that violates a computer's built-in security systems. A covert storage channel refers to depositing information in a memory or storage location that can be accessed by ...
A new attack dubbed 'SmartAttack' uses smartwatches as a covert ultrasonic signal receiver to exfiltrate data from physically isolated (air-gapped) systems. Researchers at the School of Cyber Security ...
Covert Channel Between the CPU and An FPGA By Modulating The Usage of the Power Distribution Network
use Time-to-Digital Converter sensors to observe these power variations. The sensor circuits are programmed into the FPGA fabric using only standard logic components. Our covert channel achieves a ...
The peer-to-peer network used by AirTags, Apple's just-released tracking and location devices, could be used by anyone to send small amounts of data, essentially creating a covert channel not limited ...
A new data exfiltration technique has been discovered, which uses a covert ultrasonic channel to leak sensitive information from air-gapped computers to a nearby smartphone device. The adversarial ...
[Ryan Flowers] writes in with a clever little hack that can allow you to hide data where nobody is going to go looking for it. By exploiting the fact that a web server will generally log all HTTP ...
