subsequent content, we will use SDR to capture the GSM packets in the phone during the call and use the Samsung Phone Lock screen Bypass vulnerability to directly obtain Tmsi, KC to decrypt the captured packets and extract the voice content from the call process.Maybe, we can also discuss the security of 4G LTE base station based on Gr-lte Open source project. (The Gr-lte project is an Open Source software package which aims to provide a GNU Radio LTE Receiver to receive, sync Hronize and decod

Web2 has been re-opened, and there is no clue about the reason for further hacking Another reason may be social engineering !! I only found a Cross-Site vulnerability, but I should not be able to modify it to the home page in the parent directory! Depressed .. Here we will release WM's Cross-Site vulnerability Solution By clin003 at 20070716 from: http://clin003.com/or http://blog.csdn.net/clin003/ Report vulnerabilities !! Cross-Site Cross

How to attack Hacking MongoDB MongoDB is a good database engine for both commercial and personal projects, and many domestic companies have begun to use MongoDB. Compared with traditional databases, this database is relatively new and has many security problems that you are not aware of yet. These problems can usually be caught off guard.This article mainly introduces the problems I encountered when using MongoDB and how it was used to modify Database

Thanks to several hackers, firmware 2.0 and below can use the "partially" GPU (NVIDIA rsx) feature. Recently, I have spent a lot of time on this and have a rough understanding of the GPU underlying layer and tool chain. On the PS3, there is an operating system at the bottom layer that provides hardware functional interfaces, which is called Level 1. Any operating system on it needs to interact with the hardware interface through level 1 API, which is called Level 2. With this concept, the d

Using the Cisco router configuration can easily implement VoIP, So I studied the statements related to the Cisco router configuration and shared them here, hoping to be useful to everyone. VoIPVoice over IP) is a technology that transmits voice over the Internet. It has grown with the development of Internet technology. It integrates voice technology with network transmission, and gives full play to the role of the network. This article takes the Cons

Overview The voip function of Android is available in the directory frameworks/base/voip. It includes a package that supports rtp. RTP support The RTP support package is located in the directory frameworks/base/voip/java/android/net/rtp. It mainly contains four Java classes: it represents RTP-based RtpStream, RTP-based voice stream AudioStream, AudioCodec that de

I began to study the VOIP/SIP agreement from 09, open source project also saw a few, the earliest Pjsip 05 began to push the time, began to pay attention to, also in their own winmobile project used. Later also saw Sipdroid,imsdroid (Doubango), Linphone,csipsimple (PJSIP).I think the best advantage of Linphone and Csipsimple,linphone is the full platform support, Android,ios,winphone,windows,linux,mac osx,web all support, but the quality is still unde

PSTN has been serving users for decades as a high-quality network that provides voice communication. However, with the rapid development of technology and the increasing demand for diversified services, it will eventually be replaced by the next generation network with Softswitch as the core. The Softswitch Network implements call and service control and voice and data transmission through IP-based transmission protocol, which not only solves the existing problems of PSTN, more importantly, it s

contents of the call. in a voice call, this is known as speech, and that's the media part. before being able to send and receive media, the parties must negotiate the media properties. why do you need media negotiation? For voice, the reason is that there are already different ways to represent the contents and compress it. this is similar to having several formats to play sound on your desktop (WAV, MP3 and Ogg), but in this case, the devices choose the format for the conversation. furthermore
