YARA Signatures


MalwareBazaar uses YARA rules from several public and non-public repositories, such as YARAhub and Malpedia. Those are being matched against malware samples uploaded to MalwareBazaar as well as against any suspicious process dumps they may create. Please note that only results from TLP:CLEAR rules are being displayed.

Rule name:ELF_IoT_Persistence_Hunt
Author:4r4
Description:Hunts for ELF files with persistence and download capabilities
Rule name:Linux_Ancient_Bot
Author:KSI Digital
Description:Ancient (ANCT) IoT bot ELF: persistence modules (home_persist, cron_deb, android_rc, rc_local), sysd init script and sys.service unit, toybox/busybox download chain. C2 is built at runtime, so the rule keys on the persistence layer.

Family: Ancient (Malpedia elf.ancient, aka ANCT). 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 ARMv7 build was served from hxxp://89.163.157[.]131:8080/arm7 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.
