Captured by a Cowrie honeypot (telnet, emulated ARM DVR, login admin/1234) on 2026-11-14 12:13 UTC. The attacker 217.60.242.71 ran a one-line loader that picks the build by uname -m (bot-x86_64, bot-x86, bot-arm7, bot-arm6, bot-arm5, bot-arm, bot-mips, bot-mipsel, bot-ppc, bot-sh4, bot-m68k) and downloads it via wget/curl/tftp from http://5.39.10.241/bins/bot-$BOT, saves as .b, runs it and deletes the files. Payload: http://5.39.10.241/bins/bot-arm7 . 32-bit ARM EABI4 statically linked stripped ELF, 78188 bytes, not UPX-packed. Mirai-style string table XOR-encoded with key 0x54 (watchdog paths incl. /dev/FTWDT101_watchdog, busybox kill, /proc/net/tcp, telnet credential list root/anko, hunt5759, admin/vizxv, support/7ujMko0admin), HTTP flood with Chrome 120 headers and Cloudflare/DOSarrest handling, Source Engine Query, DNS (www.google.com) floods. C2 5.39.10.241 in clear text followed by the marker "Aesky". The same host served sora.*, Cron*, hiddenbin/* and aesky/bot-mips since 2026-10-31.
