when the intercepted data transmission request is a short message transmission request, the sending of the intercepted data transmission request specifically comprises:
calling a short message module of the mobile terminal, and sending a short message by the short message module; the specific processing flow of the short message module for sending the short message is completely the same as the existing processing flow;
after transmitting the intercepted data transmission request, the method may further include:
storing the sending record in a record database so that a user can inquire the sending history record afterwards; further, the discarded data sending request can also be stored in a record database and marked as intercepted; the transmission history record contains data content, corresponding process information and other contents.
Taking the short message as an example, as shown in fig. 2, the method for preventing malicious software from sending the short message in the embodiment includes the following steps:
step 201: intercepting a short message sending request and acquiring process information corresponding to the short message sending request;
here, the intercepted short message sending request includes the content of the short message, the destination address of the short message, the sending time, and the like.
Step 202: judging whether the acquired process information can be matched with the process information in a preset list database, wherein the list database comprises the process information of a white list and the process information of a black list, executing a step 203a if the acquired process information is matched with the process information in the white list, executing a step 203b if the acquired process information is matched with the process information in the black list, and executing a step 204 if the acquired process information cannot be matched with the process information in the list database.
Step 203 a: and sending the intercepted short message sending request, and then executing step 207.
Step 203 b: the intercepted sms message transmission request is discarded, and then step 208 is executed.
Step 204: displaying relevant information containing short message content and the acquired process information to a user, executing step 205 after receiving a command of agreeing to send, and executing step 206 after receiving a command of not agreeing to send;
here, the related information includes: the content of the short message, the acquired process information, the destination address of the short message, the sending time and the like.
Step 205: and sending the intercepted short message sending request, adding the acquired process information into the process information of the white list, and then executing step 207.
Step 206: discarding the intercepted short message sending request, adding the acquired process information to the process information of the blacklist, and then executing step 208.
Step 207: the transmission record is saved to the record database, after which step 209 is performed.
Step 208: the discarded intercepted sms message sending request is saved in the record database and marked as intercepted, and then step 209 is executed.
Step 209: the current processing flow is ended.
