Report from - [URL rimossa] (1714818404) ## **Executive Summary:** The Black Lotus Labs team at Lumen Technologies is tracking a malware platform we’ve named Cuttlefish, that targets networking equipment, specifically enterprise-grade small office/home office (SOHO) routers. This malware is modular, designed primarily to steal authentication material found in web requests that transit the router from the adjacent local area network (LAN). A secondary function gives it the capacity to perform both DNS and HTTP hijacking for connections to private IP space, associated with communications on an internal network. Cuttlefish also has the ability to interact with other devices on the LAN and move material or introduce new agents. Based upon code similarities in conjunction with embedded build paths, we have found overlap with a previously reported activity cluster called HiatusRat, whose targeting aligns with the interest of the People’s Republic of China. While there is code overlap between these two malware families, we have not observed shared victimology. We assess that these activity clusters are operating concurrently. The Cuttlefish malware offers a zero-click approach to capturing data from users and devices behind the targeted network’s edge. Any data sent across network equipment infiltrated by this malware, is potentially exposed. What makes this malware family so insidiou
