The document describes the Bluetooth LE stack v3.x Bluetooth Low Energy stack library framework, API interfaces and event callbacks allowing access to the Bluetooth Low Energy functions provided by the STMicroelectronics Bluetooth Low Energy devices system-on-chip. The following Bluetooth Low Energy device supports the Bluetooth LE stack v3.x family: • BlueNRG-LP device The document also focuses on the key changes about APIs and the callback interface, Bluetooth LE stack initialization versus the Bluetooth LE stack v2.x family. This programming manual also provides some fundamental concepts about the Bluetooth Low Energy technology in order to associate the Bluetooth LE stack v3.x APIs, parameters, and related event callbacks with the Bluetooth LE protocol stack features. The user is expected to have a basic knowledge of Bluetooth LE technology and its main features. For more information about the supported devices and the Bluetooth Low Energy specifications, refer to Section 5 References at the end of this document. The manual is structured as follows: • Fundamentals of the Bluetooth Low Energy technology • Bluetooth LE stack v3.x library APIs and the event callback overview • How to design an application using the Bluetooth LE stack v3.x library APIs and event callbacks.

Table of Contents Preface 3 Android RCE Vulnerability in BNEP - CVE-2017-0781 3 Exploitation on Android 7.1 5 Target Object Selection 6 Loading the Payload into Memory 10 Grooming the Heap 12 PoC Exploit Code 16 Conclusion 16 BLUEBORNE ON ANDROID — ©​ 2019 ARMIS, INC. — 2 ​ ​ Preface Armis researchers Ben Seri and Gregory Vishnepolsky presented (October 21, 2017) a detailed explanation of the Android Remote Code Execution vulnerabilities related to the BlueBorne attack vector at the Hacktivity conference. This presentation included new information regarding the vulnerability, as well as the exploit code itself. This white paper will elaborate upon the Android RCE vulnerability and its exploitation, which are part of the BlueBorne attack vector, revealed in September 2017. BlueBorne is an attack vector by which ​ ​ hackers can leverage Bluetooth connections to penetrate and take complete control over targeted devices. Armis has identified 8 vulnerabilities related to this attack vector, affecting four operating systems, including Windows, iOS, Linux, and Android. Following Armis discoveries, Google has issued a patch to its Bluetooth stack in Android’s codebase (AOSP). This post contains additional details that were not included in the Blueborne whitepaper and unveils the exploit source code. To fully understand the ​ ​ underlying facilities that allow exploitation of the Android vulnerabilities, it is strongly suggested to read the full technical whitepaper, especially the following sections: Demystifying Discoverability, SMP, SDP and BNEP. Future publications will explore in detail the BlueBorne vulnerabilities on Linux and the “Bluetooth Pineapple” attack which affects both Android & Windows devices.

  • Symbianos by Himal Humagain Fall.Ppt
    2 Overview In this chapter we’ll present a brief overview of the different parts of Symbian OS we’re going to talk about in this book. Detailed explanations of how things work will be left to the individual technology chapters, but here we’ll take a quick look at what each area does. First we have something of an aside, but on an important topic – that of binary compatibility (BC). Symbian OS v9.0 introduced a major BC break with versions 8.1 and earlier, due to the introduction of a new (standardized) application binary interface (ABI). Therefore applications compiled against v8.1 and earlier of Symbian OS will not run on v9.1 and later. In addition to this, the platform security model requires some changes to applications using communications functionality. Depending on the application this might be as simple as adding a CAPABILITY statement to the MMP file. To start with we take a quick look at a very high-level model of how a Symbian OS-based phone is constructed in order to see where various components fit in. This isn’t to say every phone looks like this, but it is a good enough model to help understand the different layers that exist within Symbian OS. The signalling stack (also referred to as the ‘baseband’ or ‘cellular modem’) is provided by the manufacturer of the device, so Symbian OS contains a series of adaptation layers to allow standard Symbian OS APIs to be adapted to the specific signalling stack in use. Today, all shipping products use either a 2.5G GSM/GPRS or 3G UMTS (aka W-CDMA, aka 3GSM) signalling stack.
