Description

A Windows rootkit that loads at boot as a file-system filter driver and cannot be stopped until reboot (no unload function). It protects its own registry key and driver file, redirects browser traffic through an attacker-controlled proxy, and checks in with one of six hard-coded C2 servers every 5–7 seconds to download updates. It also exposes a device (\Device\MyDevice264) that lets user-mode programs kill any process and read, write, or delete files and registry keys with kernel privileges.

Indicators of Compromise:

C2 IPs: 45.248.8[.]212, 103.88.32[.]122, 103.85.86[.]3, 103.60.165[.]145, 110.42.9[.]59, 27.124.40[.]169

C2 ports: TCP 2025, 2136, 2247, 2389, 2467, 2598, 2673, 2781, 2859, 2962

C2 paths: /api/system/getSystemInfo, /api/safe/downfilelist, /driverfile/

Proxy URLs: hxxp://hxtai.mirpac[.]com/api/pac/pacReback.html?key=10073, hxxp://moren.mirpac[.]com/t.txt

Device: \Device\MyDevice264 (symlink MyDriver264)

Marker files: c:\juling.console, c:\config.pac
