The core is Mirai-derived, which is why Mirai signatures fire, but it is a distinct bot with its own C2 layer (ANCT handshake, C2 name resolved over DNS-over-TLS). This x86-64 build was served from hxxp://89.163.157[.]131:8080/x86_64 and is installed by the Ancient persist.sh dropper. It matches our YARA rule Linux_Ancient_Bot (YARAhub), which keys on the bot's persistence modules (home_persist, cron_deb, android_rc, rc_local, the sysd init script and sys.service unit). The rule matches all nine x86-64 and ARMv7 builds from this server and none of ~260 recent Mirai, Gafgyt and Mozi samples.
