The Linux Shell (ShellShock) vulnerability is causing a global information security crisis. hackers have developed a worm that automatically spreads through the shell (ShellShock) vulnerability. According to an analysis from Kingsoft drug overlord's Security Center, the main purpose of the worm virus is to intrude a DVR (hard drive video recorder) device in China, hackers use these devices to dig for litecoin (a digital currency similar to Bitcoin), a

1. When the pointer is used as a parameter, the ref or out keyword must be used in C #, especially the struct pointer. It is not appropriate to report memory read errors even if no error data is reported. Haha

This function is mainly used to expand STB to PVR/DVR. After such expansion, you need to add a large storage device to store data. EPG is an indispensable software for PVR/DVR. It provides programs to users in advance, and users place orders through reservation ", PVR/DVRs Enable Automatic Recording of programs based on the user's reservation. At present,

I received several ZDI vulnerability bulletins that day, one of which is MS11-092. Due to the recent interest in file format vulnerabilities, PatchDiff2 compares the patch files. After comparison, the thief did not want to check whether there is a ready-made POC. GOOGLE has found some of hellok students in the snow hair "MS11-092 patch comparison analysis" this post. Oh! The enthusiasm of the brokers is so high that it is terrible! Hellok analyzed that this could be a heap overflow vulnerability
demand for a large amount of data, DVD forum in the Development of DVD-R specifications, take the following four points as the basis:1. DVD-R is a new type of record system with the same CD-R.
2. After recording the DVD-R optical disc, It is interchangeable with 100% of the general DVD dial-on.
3. Supports multi session recording
4. DVD-R optical discs have extremely high cost/performance values.
DVD-R is led by pioneer company development can write a DVD specification, the earliest development

, you only need to log on to the video server over the network to view the monitoring images. Because of the TCP/IP architecture, the video server is very convenient to use. Any monitoring site only needs an IP address and can be configured with a fixed IP address to install the video server.
A standard video server also requires RS232, rs422, or RS485 control interfaces and level input/output interfaces. The serial port can be used to conveniently implement remote control of cameras, cloud plat
