Objective
With the development of the Internet, more and more companies have introduced intelligent routers, these intelligent routers have brought many convenient functions to users, but also adopted some traditional routers do not have the security characteristics, this article in a brief analysis of these security features, for the relevant technical personnel for reference.
Overview
Traditional routers intentionally or unintentionally use a variety of unsafe features, such as the back doo
higher than that of the Nokia N95. Now I believe that the iPhone's CPU is a Samsung S5L8900, which has a A-GPS and 3G functionality (this is the case later), but the iPhone's GSM module uses another completely independent system, that's what we often call baseband. This baseband has its own firmware (operating system) and CPU (It's a S-GOLD2, and Siemens's cell phone also uses this CPU, baseband also has its own flash memory used to record the curren
concerned about the RF interface, its testing and troubleshooting technology should be completely different from the wired LAN. ”
Integrate wired and Wireless LAN Security solutions, would anyone like to?
Integrated integration systems such as SonicWALL and fortinet security companies can provide integrated solutions for small, simple companies. Security companies have expanded their UTM (Unified threat Management) systems for access to wireless LA

2. The mobile phone number is iPhone 4.GSM version(Non-CDMA)
3. the IOS version to be upgraded is 5.0.1, and the previous version is 5.0.1.
4. This iPhone was jailbroken before, and all cydia had SHSH backups
5. white apple
2. Preparation
1. Download ios5.0.1 firmware
Go to http://iphone.91.com/fw/download the ios5.0.1
firmware of the entire system of the bunion socket is more than 260 KB, including the entire hardware initialization, FreeRTOS system and TCPIP protocol stack, wireless management, and upper-layer business logic, the use of FTFS to streamline the file system is very tight and streamlined. Next we will introduce the socket startup process.
2.2.1 system guidance process
We get the updated firmware (BL_SP2-27
How does the Fibonacci K2 router brush machine? (This tutorial also applies to K1, K1s models).
Briefly, brush machine is divided into two parts, the first is to brush into the breed Web console, which allows you to change the different firmware at will, the second is on this basis to brush your favorite version of the firmware. This paper takes ASUS Padavan
know that the operating system from Silicon Valley to do a smart watch company called Pebble Watch, They are from the Kickstarter of the United States on the Internet to make money to do smart watches, they are used FreeRTOS.
Its features are dapper, the smallest FreeRTOS core contains only 3. c Files (task.c,queue.c, list.c) and a small number of header files, the streamlined binary files can be as small as 10 k, very suitable for this Low-power intelligent device operating system, The entire
Iboot is the boot loader on iOS devices, and when you perform a system recovery or upgrade in recovery mode, Iboot detects the firmware version you are upgrading to make sure that the firmware version you are upgrading is newer than the firmware version of the current system (the version number is higher). If the firmware
will be a single tap, which is a separate ARM Kernel ...... But there are actually three taps ...... Does this film have three ARM kernels?
After some research, I found that this chip really has three kernels. Two are Feroceon kernel, is more awesome like the kernel of arm9-, There Is A Crotex-M3 kernel, relatively small, more like the core of the microcontroller. After a while (and later studies), these controllers have different functions:
Feroceon 1 processes physical read/write operations
First, the basic knowledge of mobile phone1. Firmware, brush firmware, firmware versionFirmware refers to the cured software, in English, firmware, which is the flashrom of writing a system program to a particular hardware system.The handset firmware is equivalent to the pho
When the Debian 7 system is installed, the network device will be detected, this time will be prompted to say there is a missing firmware, whether to load from removable media, the installation of the choice of No. Continue to install the system. Installed after the discovery of the wireless network firmware is missing, unable to link to the wireless network, this time only remembered to install the system

This upgrade application must be used together with the recovery under/recovery/sbin,

Linux Kernel 3.8 later added support for kernel-loaded firmware, so systemd after v217 to go beyond user loading firmware supportOrangepi to the present (January 6, 2016) is still using the 3.4.39 kernel, which does not support the kernel load firmware. Wily (Ubuntu 15.10) uses the SYSTEMD is v225, does not support user-state loading
. On this premise, I thought of a tortuous solution. In this mode, the recorded GPS position must be absolute, because only in this way can the programmer know whether the recorded position is correct. Activate this mode by placing a special file in the memory card. However, only the firmware of the reverse as100v is known for the special files. You want to know how to enter the debugging mode. You need to obtain the
Correct position for Pwn smart watch Removal
Although specialization is the key to many fields, I personally think that too much professionalism in the field of information security will lead to narrow vision and one-sided views. Now I want to try out a field that I don't like very much. This article is about something I hate for a long time: embedded hardware reverse engineering.0x00 motivation
Currently, Iot devices have many attractive points:

the FIFO in the endpoint 2 has data, can read and write, when the sloe is valid, enable SLRD, in the IFCLK rising edge, read the data on the FD Bus, FX2 corresponding FIFO internal pointer automatically accumulate, Be prepared for the next read operation. Scenario Two: FIFO is empty, no data When the continuous read operation, the FLGAC valid state, the Sloe and SLRD are set to an invalid state, waiting for data in the FIFO to read the operation again, the data bus maintains a high impedance s
Samsung Galaxy Note4 is Samsung's flagship model this year, while maintaining excellent performance while also bringing a number of features, but as an Android phone, it is inevitable to brush the machine to make the phone more streamlined, especially for Samsung's mobile phones, Many features and applications are not really useful to consumers.
Samsung's mobile phone has a large number of versions, so it takes a lot of attention to brush the machine, but the general edition is obviously more s
