Ayuntamiento de Valdemoro
About the organisation
Ayuntamiento de Valdemoro is the municipal government of Valdemoro, a town in the Madrid region of Spain. The site valdemoro.es is its official portal for residents, local news, and access to administrative services. The council plans and delivers local public services such as urban maintenance, social and cultural programmes, education and sports facilities where it is responsible, and citizen support. It passes local regulations within national and regional law, manages municipal assets, and interacts with higher tiers of government on regional and national programmes. In short, it is the local authority that governs and runs day-to-day public administration for the municipality.
What the listing means
Ayuntamiento de Valdemoro appeared on the kairos leak site on 11 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 06 May 2026, 5 days before the listing. This group has published 4 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing Ayuntamiento de Valdemoro as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on valdemoro.es, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Public Sector 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.
