CSDaisyBuildBlockStealer is a CyStack-coined identifier for
a Daisy Private cloud panel that wraps the four-key
Build Path / Build ID / Build Version / Build Comment
block body in the digit-obfuscated Daisy Cloud per-line
watermark. Observed inside BANANA VIP <DD>-<MM>-<YYYY> and
sibling repackager archives whose top folder wraps a
<32-char>_<YYYY>_<MM>_<DD>T<HH>_<MM>_<SS>_<micros>/ UserInformation.txt victim path.
The body opens with the pipe-bordered Daisy Cloud ASCII
banner block (pricing tiers, t.me/UP_DAISYCLOUD channel
URL, per-line anti-leech ASCII art), then every payload line
is prefixed with a digit-obfuscated Daisy Private cloud
watermark plus a 4-9 lowercase alphabetic gibberish token.
The obfuscation defeats naive substring-search leak checks:
a single grep for Daisy Private cloud cannot extract the
channel name from any individual line.
After stripping the per-line watermark and gibberish, the
body carries: User time (ISO wall-clock), HWID (MD5-
shape hex), PC Name, User Name (HOSTNAME\USERNAME),
CPU, GPU, Memory (GB-suffixed), OS (bare, may
localize the vendor prefix e.g. Майкрософт), Active window, Build Path (sample execution path), Build ID
(builder identifier), Build Version, Build Comment,
Admin rights (true/false), IP, GEO (ISO-2), and
Resolution. Field vocabulary matches the sibling
bare-body CSBuildBlockStealer layout already documented
under the @ft7links / @BRADMAX / @updh1 resellers.
The @UP_DAISYCLOUD channel is described by VERITI and
CyberSecurityNews as a Telegram credential-trading channel
that potentially resells RedLine Stealer logs. Both sources
qualify the attribution as speculative. No curated CTI
vendor confirms a canonical family attribution for the
underlying BuildBlock body, so family stays CyStack-coined
with the Daisy Cloud panel brand and channel handle
preserved as attribution context.
