By Chetan Raghuprasad, Asheer Malhotra and Vitor Ventura, with contributions from Matt Thaxton. Cisco Talos discovered a new attack framework including a command and control (C2) tool called "Alchimist" and a new malware "Insekt" with remote administration capabilities. The Alchimist has a web interface in Simplified Chinese with remote administration features. The attack framework is designed to target Windows, Linux and Mac machines. Alchimist and Insekt binaries are implemented in GoLang. This campaign consists of additional bespoke tools such as a MacOS exploitation tool, a custom backdoor and multiple off-the-shelf tools such as reverse proxies. Cisco Talos has discovered a new single-file command and control (C2) framework the authors call "Alchimist [sic]." Talos researchers found this C2 on a server that had a file listing active on the root directory along with a set of post-exploitation tools. Cisco Talos assesses with moderate-high confidence that this framework is being...
