Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...
GrapheneOS randomizes Wi-Fi MAC addresses per connection (to a Wi-Fi network) by default, instead of the Android per-network default. [ 6 ] [ 17 ] GrapheneOS includes automatic phone reboot when not in use, automatic WiFi and Bluetooth disabling, and system-level disabling of USB-C port, microphone, camera, and sensors for apps.
MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device. The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an ...
Another approach that has been tested is truncating the MAC Address by removing the Organizationally unique identifier (the first 24 bits of the 48 bit MAC Address). [7] However, as only 0.1% of the total Organizationally unique identifier space has been allocated and not all manufacturers fully utilise their allocated MAC Address space, this ...

To avert this practice, Apple started using random MAC addresses in iOS devices while scanning for networks. [19] Other vendors quickly followed suit. MAC address randomization during scanning was added in Android starting from version 6.0, [20] in Windows 10, [22] and in Linux 3.18. [23]
From the daily tracing key a 16-byte temporary Rolling Proximity Identifier is generated every 10 minutes with the algorithm , = ((, | |),), where () is a HMAC function using SHA-256, and is the time interval number, representing a unique index for every 10 minute period in a 24-hour day. The Truncate function returns the first 16 bytes of the ...
Android 10 (codenamed Android Q during development) is the tenth major release and the 17th version of the Android mobile operating system. It was first released as a developer preview on March 13, 2019, and was released publicly on September 3, 2019.
