Generative artificial intelligence technologies such as OpenAI’s ChatGPT and DALL-E have created a great deal of disruption across much of our digital lives. Creating credible text, images and even audio, these AI tools can be used for both good and ill. That includes their application in the cybersecurity space.
Introduction The use of deep neural networks has significantly improved the performance of machine learning in fields such as image […]
Introduction Many organizations are transitioning their security management to the cloud, where it is much easier to collect and access […]
GPT is a powerful text generation model, but its text generation is unconstrained. This session will discuss how to control GPT to produce sentences which meet specific style or content requirements. The session will review approaches that allow attendees to drive GTP to write SPAM and HAM messages and will demonstrate how to convert GPT into a SPAM filter which detects the generated SPAM.
Targeted phishing emails are a major cyber threat on the Internet today and are insufficiently addressed by current defenses. In this paper, we leverage industrial-scale datasets from Sophos cloud email security service, which defends tens of millions of customer mailboxes, to propose a novel Transformer-based architecture for detecting targeted phishing emails. Our model leverages both natural language and email header inputs, is more computationally efficient than competing transformer approaches, and we show that it is less prone to adversarial attacks which deliberately replace keywords with typos or synonyms.
