Obviously, the drawings described below are only some embodiments of the present disclosure.

[0024] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] The inventors have found that if password keywords (such as password, pass, pwd, jdbc, etc.) are searched in the code to detect whether there are hard-coded passwords in the code, the detection accuracy is usually low and the detection efficiency is low, and the staff needs to perform manual secondary confirmation. The reasons for the low detection accuracy are mainly two aspects. On the one hand, there may be a named field with the same name as the password keyword in the code, but the field is not actually a password; on the other hand, the password may be used directly in the code instead of using the password keyword to represent the password. The reason for the low detection efficiency is that when searching for password keywords, character matching must be performed in the entire code. In view of this, the inventors provide a code detection method that can more accurately and efficiently detect hard-coded passwords in the code.

[0026] Combine the following Figure 1 Some embodiments of the disclosed code detection method are described.

[0027] Figure 1 FIG. 1 is a flow chart showing a code detection method according to some embodiments of the present disclosure. Figure 1 As shown, the code detection method includes steps S101 to S109, wherein steps S101 to S104 are the preparation stage, and steps S105 to S109 are the detection stage.

[0028] (Preparation stage)

[0029] In step S101 , the file type of the file is determined.

[0030] The file type includes binary type and non-binary type. The file type can be determined based on the file name suffix, for example, a file with the file name suffix .bin is a binary file. The file type can also be determined based on the magic number of the file. For example, if the first four bytes of the file output through the Linux command line are 7f45, then the file is a binary file.

[0031] If the file type is a non-binary file, step S102 is executed. In step S102, the code in the file is preloaded.

[0032] In the case where the file type is a binary file, steps S103 to S104 are executed. In step S103, the file is reverse processed, for example, using a reverse tool such as IDA (Interactive Disassembler) software to reverse process the file. In step S104, the code in the reverse processed file is preloaded.

[0033] (Detection phase)

[0034] In step S105 , functions and parameters in the code are identified.

[0035] After identifying the functions and parameters in the code, the code can be abstracted into a syntax tree.

[0036] In step S106, the connection parameters for calling the network function and the definition parameters of the connection parameters are searched from the parameters.

[0037] The functions in the code include network functions. For example, when a socket connection is established in the code, a function in the socket library is called, and the function in the socket library belongs to a network function. Then, by detecting the connection call to the network function, or by detecting keywords such as "connect" in the code, the connection parameters for calling the network function can be found. Assume that the connection parameter is b, and the definition parameter of the connection parameter b is a. Those skilled in the art should understand that the actual number of connection parameters can be multiple. In order to facilitate the description of the technical solution, it is explained here from the perspective of a single connection parameter.

[0038] In step S107, a parameter processing function that processes the definition parameter as a connection parameter is searched from the functions.

[0039] Those skilled in the art will appreciate that the functions in the code include parameter processing functions.

[0040] In step S108, it is determined whether the connection parameter is a hard-coded password according to the parameter processing function and the definition parameters.

[0041] If the definition parameters and the connection parameters are different after being processed by the parameter processing function, the connection parameters are not hard-coded passwords; if the definition parameters and the connection parameters are the same after being processed by the parameter processing function, or the parameter processing function is not found, the connection parameters are hard-coded passwords.

[0042] In the case where the connection parameter is a hard-coded password, step S109 is executed. In step S109, a detection report for detecting the hard-coded password in the code is output.

[0043] The above embodiment is applicable to white box testing and gray box testing scenarios. After preloading the code, by identifying, searching and judging the functions and parameters in the code, the hard-coded passwords in the code can be detected more accurately and efficiently, solving the problems of high false positive rate, high false negative rate, low detection efficiency and the need for manual secondary confirmation by staff when detecting hard-coded passwords in traditional code detection methods.

[0044] In some embodiments, the code detection method further includes steps S110 to S112.

[0045] In the case where the connection parameter is not a hard-coded password, step S110 is executed. In step S110, it is determined whether the parameter processing function processes the definition parameter into the connection parameter using the encryption parameter.

[0046] If the parameter processing function processes the definition parameter into a connection parameter using the encryption parameter, step S111 is executed. In step S111, it is reported that a strong processing password is detected in the code.

[0047] In the case where the parameter processing function processes the definition parameters into connection parameters using the encryption parameters, the connection parameters cannot be obtained by performing a simple processing operation on the definition parameters. In this case, it is determined that a strong processing password exists in the code.

[0048] If the parameter processing function does not use the encryption parameter to process the definition parameter into the connection parameter, step S112 is executed. In step S112, it is reported that a weak processing password is detected in the code.

[0049] In the case where the parameter processing function processes the definition parameters into connection parameters without using the encryption parameters, the connection parameters can be obtained by performing a simple processing operation on the definition parameters. In this case, it is determined that there is a weak processing password in the code.

[0050] These embodiments can not only accurately and efficiently detect hard-coded passwords in the code, but also detect weakly processed passwords and strongly processed passwords in the code.

[0051] Combine the following Figure 2 Some embodiments of outputting a detection report for detecting hard-coded passwords in code are described.

[0052] Figure 2 A schematic diagram of a process for outputting a detection report for detecting hard-coded passwords in code is shown in some embodiments. Figure 2 As shown, the method includes steps S2091 to S2094.

[0053] In step S2091, determine whether the code has been obfuscated.

[0054] In the obfuscated code, parameters and functions are in unreadable forms such as "C" and "D".

[0055] If the code is not obfuscated, step S2092 is executed. In step S2092, the connection parameters are output and a hard-coded password is reported to be detected in the code.

[0056] If the code is obfuscated, step S2093 is executed. In step S2093, the code is matched with a password keyword (e.g., password, pass, pwd, jdbc, etc.), the parameters in the code that match the password keyword are output, and a hard-coded password is detected in the code. Those skilled in the art will understand that if there is no parameter matching the password keyword in the code, it indicates that the password is difficult to detect from the code and the security of the code is relatively high.

[0057] If there is a hard-coded password in the code, then no matter whether the code is obfuscated or not, this embodiment can detect the hard-coded password from the code and output a detection report of detecting the hard-coded password in the code.
