CSDaisyBonusProcSoftStealer is a CyStack-coined identifier for
a heavily-stripped information.txt panel observed inside
Daisy Private Cloud - <N> Pcs - <DD> <Mon> - Bonus.7z
aggregator packs distributed by the @UP_DAISYCLOUD Telegram
channel. Per-victim folders follow a flat
<CC><HWID-30-CHARS>_<YYYY>_<MM>_<DD>T<HH>_<MM>_<XX>_<N>/
naming convention (the country code is the leading two
letters, the HWID is a 30-character alphanumeric block, and
the trailing segment encodes a timestamp).
The body ships only two surviving sections from the underlying
panel: a 2-space-indented [<PID>] <name>.exe process list
and a [Software] Vidar-style section header followed by a
2-space-indented program inventory. No banner, no IP / Country / HWID / Computer Name field block, and no Redline /
Lumma / Vidar canonical anchors survive. The
leading-PID-bracket process-list shape is the reverse of Aura
Stealer and StealC, which emit process entries as <name>.exe [<PID>] (PID after the exe), so the two layouts remain structurally distinct.
Family attribution is provisional pending a published threat-intel mapping. Public reporting documents the @UP_DAISYCLOUD
channel as a Telegram credential-trading channel potentially
linked to RedLine Stealer, but the heavily-stripped Bonus-pack
body carries no Redline-canonical fields, so the Redline lineage evidence that the sibling CSDaisyCloudStealer
watermarked sibling supports for canonical
UserInformation.txt cannot be carried over. The Bonus pack
may ship victim records from a different underlying stealer
than the canonical Daisy Cloud channel, or the same stealer
with a different stripping configuration. The
CSDaisyBonusProcSoftStealer literal captures the discovery;
update this tracking profile if a public writeup later
identifies the underlying builder.
