Rapid development of malicious content detectors

Abstract

Methods and systems are described for developing a malicious content detector to identify new malicious text content, such as phishing messages, malicious documents, and/or malicious web content. A computing device is used to generate input data which contains an instruction, examples of content, and content to be analyzed. The examples include malicious and benign content samples, designed to recognize similar malicious content. The computing device feeds this input into a generative language model, which produces text labels that indicate the maliciousness of the content to be analyzed. The methods and systems enable rapid development of security protection by leveraging a small number of malicious samples, instead of training with a large dataset of new training samples.
