Unverified claim. This entry reproduces a listing published by the cmdorganization group on its own extortion site. Attackers routinely exaggerate or fabricate victims. Nothing here confirms that Goodstone Group suffered a breach, or what data was actually taken.

What the listing means

Goodstone Group appeared on the cmdorganization leak site on 14 May 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated — the attack itself is dated 18 April 2026, 26 days before the listing. This group has published 12 claims in the last 30 days and remains active.

Recommended actions

Treat any unsolicited message referencing Goodstone Group as suspicious — leaked data gets weaponised for phishing within days.
If you hold an account on www.goodstone.com.au, change that password now, update it anywhere you reused it, and enable two-factor authentication.
Watch for follow-on extortion: stolen data is often re-leaked or resold after the initial listing.
A leak-site listing is a claim made by the attacker, not a confirmed breach — check the organisation's own disclosures before acting on it.
