12:25Tencent basaltic laboratory in Yang shared a bar code system for the general method of attack, the attacker only needs a group of special design of bar code can be realized in the system execute arbitrary code, and to complete this attack requires only a piece of paper. One dimensional bar code through the black and white space, according to a certain rules to record information. Bar code contains static area, start character, data character, terminator. Code reader first to get the image, and then decode the conversion (UPC/EAN, Code 39, Code 128 and other protocols standard), data transmission (RS232, PS/2, etc.). At present, only one-dimensional bar code, the agreement there are dozens, of which code 128 not only supports the digital storage, letters, also supports all of the ASCII characters, efficient, high density of information, also contains four customizable function code, there are three coded character set: CodeA, CodeB, CodeC. Almost all of the code scanning device support it. Known barcode security issues include: triggered by the bar code overflow, triggering the format string, triggering SOL injection, triggering XSS. In addition, there can be used to predict the use of bar code - forgery attacks, copy attacks, phishing attacks /CSRF (mainly two-dimensional code). Basaltic laboratory found that the output of a lot of bar code reader is a PS / 2 or hid keyboard, through the code128 is possible "input" Ctrl+* and of the terminal pose a threat. Then he demonstrated multiple attacks demo.
