point, the Payload length value in the Code is written by the original author 09f3. I think this is also one of the main causes of vulnerability exploitation failure. Therefore, we recommend that you calculate the length before sending the Payload. A very important point about the first chunk of the payload. Notice the first 4 bytes "00 09 f3". The "09 f3" is the specification for the TOTAL payload length in bytes. The Payload length value can be within the same range. The cf_hb of our team

In the switching regulated power supply circuit, the transistor v works alternately in the switching state of conduction-cutoff and cutoff-conduction under the excitation signal, and the conversion speed is very fast, generally, the frequency is about 50 kHz. In some advanced countries, it can be several hundred or nearly 1000 kHz. This makes the

You cannot directly set the content of the text using the setnodevalue () method of the element object. Instead, you must use the setnodevalue () of the created Text object () to add the created ele

0 V level of the device is different from the 0 V level of the B point, this will lead to a large amount of current flowing from devices with high potential to devices with low potential. How can we solve this problem?The transformer (isolating transformer) device appears. It filters the differential signals sent by PHY with the difference mode coupled coil to enhance the signal, and is coupled to the othe

The data is transmitted through a pair of twisted pairs, and the ground uses a shielding layer. These applications often require low power consumption because many remot
