Researchers discovered an unprotected TrueDialog database hosted by Microsoft Azure with diverse and business-related data from tens of millions of users. The insecure database was linked to many aspects of TrueDialog s business, researchers said. TrueDialog provides bulk SMS services for small businesses, colleges and universities, which means that the majority of the messages were business related. Bad actors also have an opportunity to find and exploit vulnerabilities within TrueDialog’s system by accessing the logs of internal system errors included in the exposed data.
