Overview of unsolicited SMS countermeasure function

Recently, many phishing cases using SMS of mobile phones have occurred. In addition, not a few SMS that spoofed the sender have arrived. Therefore, at the same time as implementing a new countermeasure function, the already provided "phone number mail rejection / permission" function will be strengthened. Phone number Rejection / permission (enhancement of functions) The sender of SMS is displayed as a phone number in principle. However, in the SMS sent by the distributor (system), the sender display can be an alphabetic character string. There are also unsolicited SMS that exploit this to hide the source. Therefore, in the mail rejection / permission setting, it is possible to specify by "alphabet character string" in addition to "phone number". Rejecting spoofed SMS By "applying" SMS transmission by the above system, it is possible to hide (mask) the original sender and send SMS. This can also be abused to send SMS that "fake" the sender. Therefore, we will add a function that can reject SMS that hides the original sender as "spoofing SMS". Rejecting SMS with URL Links Many SMS phishing cases are triggered by tapping (clicking) the URL in the body of the SMS. Therefore, it will be possible to reject the reception of SMS whose URL is described in the text. This rejection setting applies to SMS whose sender is a mobile phone number. Rejection of SMS with URL link The sent SMS is analyzed by machine learning-based AI (artificial intelligence), and if it is determined to be annoying SMS, reception is rejected.
