Aspects of the disclosure relate to identifying potentially malicious messages and generating instream alerts based on real-time message monitoring. A computing platform may monitor a plurality of messages received by a messaging server associated with an operator. Subsequently, the computing platform may detect that a message of the plurality of messages is potentially malicious. In response to detecting that the message of the plurality of messages is potentially malicious, the computing platform may execute one or more protection actions. In executing the one or more protection actions, the computing platform may generate an alert message comprising information indicating that the message of the plurality of messages is potentially malicious. Then, the computing platform may send the alert message to the messaging server, which may cause the messaging server to deliver the alert message to a computing device associated with an intended recipient of the message.

Aspects of the disclosure relate to providing secure shortened URLs in character-limited messages. A computing platform may receive one or more character-limited messages sent to a user device. The computing platform may detect a URL within the one or more character-limited messages for replacement and generate a shortened URL corresponding to the detected URL, wherein a domain of the shortened URL is hosted by the message security system. The computing platform may then modify the one or more character-limited messages by replacing the URL with the shortened URL, and then cause transmission of the modified one or more character-limited messages to the user device. Next, the computing platform may receive, from the user device, a request to access the shortened URL, and redirect the user device to the detected URL corresponding to the shortened URL.

Aspects of the disclosure relate to detecting and preventing transmission of spam messages using modified source numbers. A computing platform may detect that a first message, sent to a recipient device from a sender device, includes suspicious content. Subsequently, the computing platform may receive, from the recipient device, user interaction information indicating that a user of the recipient device has sent a reply message in response to the first message. Then, the computing platform may generate a modified message by modifying a first source number corresponding to the reply message. Next, the computing platform may cause transmission of the modified message with the modified first source number to the sender device. Thereafter, the computing platform may intercept one or more additional messages between the sender device and the modified first source number and redirect the one or more additional messages.

Aspects of the disclosure relate to providing commercial and/or spam messaging detection and enforcement. A computing platform may receive a plurality of text messages from a sender. It may then tokenize the plurality of text messages to yield a plurality of tokens. The computing platform may then match one or more tokens of the plurality of tokens in the plurality of text messages to one or more bulk string tokens. Next, it may detect one or more homoglyphs in the plurality of text messages, and then detect one or more URLs in the plurality of text messages. The computing platform may flag the sender based at least on the one or more matching tokens, the one or more detected homoglyphs, and the one or more detected URLs. Based on flagging the sender, the computing platform may block one or more messages from the sender.

Bulk messaging detection and enforcement

Aspects of the disclosure relate to message verification. A computing platform may generate a cryptographic key pair comprising a public key and a private key. The computing platform may publish, to a server, the public key. The computing platform may generate a short message service (SMS) message. The computing platform may sign, using the private key, the SMS message, which may include computing a cryptographic hash of the SMS message using the private key and embedding the cryptographic hash in an SMPP field of the SMS message. The computing platform may send, to a downstream computing system, the signed SMS message, where the downstream computing system may be configured to validate the signed SMS message using the cryptographic hash embedded in the SMPP field of the SMS message and by accessing the public key.

Aspects of the disclosure relate to detecting and protecting against cybersecurity attacks using unprintable tracking characters. A computing platform may receive a character-limited message sent to a user device. Subsequently, the computing platform may detect that the character-limited message sent to the user device includes suspicious content. Then, the computing platform may generate a modified character-limited message by inserting one or more special characters into the character-limited message and cause transmission of the modified character-limited message to the user device. Next, the computing platform may receive, from the user device, a spam report that includes the modified character-limited message. Then, the computing platform may identify a presence of the one or more special characters included in the modified character-limited message and adjust one or more filters based on the identification.

Car wing

A method of showing the inside status of a vehicle via a plurality of first icons is provided. The method includes the following steps: (a) disposing a status read device on the vehicle to monitor and report a plurality of operation statuses of the vehicle; (b) transforming the plurality of operation statuses into a plurality of corresponding first icons by an information transform unit; and (c) displaying the plurality of first icons corresponding to the plurality of operation statuses on a first display to show the inside status of the vehicle for the users or drivers outside the vehicle. The first display faces outward and is disposed on the left side, right side or rear side of the vehicle.
