Serverless Trap Honeyλ is a serverless framework-based application that creates and monitors fake HTTP endpoints for deception purposes. The tool automatically generates URL honeytokens that can be strategically placed in various locations including email inboxes, documents, browser history, or embedded as hidden links in web pages. These honeytokens serve as breadcrumbs to lure attackers toward monitored traps, enabling detection of human attackers, malicious insiders, content scrapers, and malicious bots. The application utilizes the Cymon API v2 for threat intelligence integration and operates on a pay-what-you-use model across multiple cloud providers. Built on the Serverless framework, it supports deployment on Amazon Web Services (AWS), Microsoft Azure, IBM OpenWhisk, and Google Cloud, though it has been primarily tested on AWS. The tool provides automated monitoring capabilities to alert when honeytokens are accessed, indicating potential security threats or unauthorized activity.
