Abstract: A computer-implemented method to provide a secure uniform resource locator (URL) shortening service is described. A URL is received via a browser provided on a display of a computing device. A shortened URL is generated to represent the received URL. A determination is made as to whether a classification assigned to a web site associated with the shortened URL is valid. Upon determining that the assigned classification is not valid, the web site is evaluated in order to assign an updated valid classification to the web site.

Abstract: A computer-implemented method for detecting potentially malicious content within NFC messages may include identifying an NFC message received by a mobile device via wireless transmission from an NFC device located in proximity of the mobile device. The method may also include determining that the NFC message is formatted in a suspicious format type capable of importing potentially malicious content into the mobile device and then scanning the NFC message for potentially malicious content in response to the determination. The method may further include detecting at least one instance of potentially malicious content while scanning the NFC message. In addition, the method may include performing at least one security action on the mobile device in response to the detection of the instance of potentially malicious content within the NFC message. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A computer-implemented method for providing security information about quick response codes may include (1) identifying a matrix barcode embedded in a web page, (2) determining that the matrix barcode includes a link to an Internet resource, (3) determining the trustworthiness of the Internet resource referenced by the matrix barcode, and then (4) augmenting the matrix barcode with a visual augmentation that is based at least in part on the trustworthiness of the Internet resource. Various other methods, systems, and computer-readable media are also disclosed.
