Unverified claim.
This entry reproduces a listing published by the lamashtu group on its own extortion site.
Attackers routinely exaggerate or fabricate victims. Nothing here confirms that
VOLTERRIES suffered a breach, or what data was actually taken.
About the organisation
Volterres, a subsidiary of the Eiffage group, is reinventing the supply of green electricity for businesses and public sector players.
What the listing means
VOLTERRIES appeared on the lamashtu leak site on 15 April 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated. This group has not published new claims in the last 30 days.
Recommended actions
- Treat any unsolicited message referencing VOLTERRIES as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on volterres.fr, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Energy organisations should review this group's known TTPs and validate detection coverage against them.
- 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.
