Discover how Dropbox was exploited in a sophisticated phishing attack that leveraged AiTM tactics to steal credentials during the open enrollment period.
Check Point Research is tracking an ongoing, large scale and sophisticated phishing campaign deploying the newest version of the Rhadamanthys stealer (0.7). We dubbed this campaign CopyRh(ight)adamantys. This campaign utilizes a copyright infringement theme to target various regions, including the United States, Europe, East Asia, and South America. The campaign impersonates dozens of companies, while each email is sent to a specific targeted entity from a different Gmail account, adapting the impersonated company and the language per targeted entity. Almost 70% of the impersonated companies are from Entertainment /Media and Technology/Software sectors. Analysis of the lures and targets in this campaign suggests the threat actor uses automation for lures distribution. Due to the scale of the campaign and the variety of the lures and sender emails, there is a possibility that the threat actor also utilized AI tools. One of the main updates in the Rhadamanthys stealer version according to claims by the author, is AI-powered text recognition. However, we discovered that the component introduced by Rhadamanthys does not incorporate any of the modern AI engines, but instead uses much older classic machine learning, typical for OCR software.
