CSWmicDumpStealer is a CyStack-coined identifier for a
snake_case system_info.txt panel observed inside !! 2026 JAN.part01.rar aggregator packs distributed via Telegram log
channels. Per-victim folders follow a
<id>_<2-hex>_<ip>_<DD-MM-YY>/system_info.txt layout. The
body opens with an uppercase === SYSTEM INFORMATION ===
header and is composed of snake_case key: value lines where
many of the values are raw stdout from Windows command-line
tools: wmic baseboard get, wmic bios get, wmic memorychip get, wmic memphysical get, wmic diskdrive get, wmic computersystem get, wmic path Win32_VideoController get,
wmic os get LastBootUpTime, plus ipconfig /all and ver.
The fixed-width WMIC tabular output is captured verbatim, with
the column-header row sitting on the same line as the field
key.
The snake_case naming convention plus the "shell out to wmic
and stash the stdout" pattern strongly suggests a Python-based
stealer (subprocess.check_output("wmic ...") shape) but no
surveyed Python-stealer write-up (Inf0s3c, XillenStealer,
Akira, ExelaStealer, BlankGrabber) documents this exact field
set.
Family attribution is provisional pending a published
threat-intel mapping for this layout. Public reporting plus
public stealer-format catalogues do not document a family
using this exact snake_case field set. The CSWmicDumpStealer
literal preserves the panel's most distinctive trait (raw WMIC
stdout dumped into snake_case fields) as the suffix; rename
the CyStack tracking name if a public writeup later identifies the
underlying builder.
