A computer-implemented method of detecting synthetic text in an email may determine whether the sender of a received email is a named individual and if so, may extract textual content from the email. When the size of the extracted textual content is at least equal to a configurable size threshold, the extracted textual content may be analyzed using a plurality of synthetic text detection engines, each being configured to generate a synthetic text detection score. The synthetic text detection scores may then be compared to a respective score threshold associated with each of the synthetic text detection engines. An action to warn and/or protect the recipient of the email may be carried out when one or more synthetic text detection scores is at least equal to a respective associated score threshold, which is indicative of a detection of synthetic textual content in the received email.

A computer-implemented method of generating security awareness training samples may include receiving, structuring and storing information about a user of an organization into an organization knowledge base and selecting and fetching at least one training template, each including an electronic message template and a prompt template for a large language model. The prompt template(s) and the electronic message template(s) may then be specialized using the information about users of the organization stored in the organization knowledge base. The specialized prompt template(s) may then be submitted to a large language model artificial intelligence system. Textual content may then be received from the large language model responsive to each submitted specialized prompt template. A security awareness training sample may then be generated for each submitted specialized prompt template using the corresponding generated textual content received from the large language model and the corresponding specialized electronic message template(s).
