The translated JPCERT/CC analysis links YamaBot to Lazarus activity and describes the malware as a Go-based tool targeting both Windows and Linux environments. YamaBot communicates with C2 servers through HTTP requests, using a Base64-encoded User-Agent and RC4-encrypted, Base64-encoded terminal information or command results in cookie fields. The Linux version is described as supporting shell command execution through /bin/sh, while the Windows version implements multiple commands including download, information reporting, and shell execution. The excerpt identifies C2 locations such as www.karin-store.com/recaptcha.php, yoshinorihirano.net/wp-includes/feed-xml.php, and 213.180.180.154/editor/session/aaa000/support.php, making the report useful for host and server-side incident review.
