About the organisation
NGO sector. Domains: actionaid.org, tacosa.org.za, immigration.go.tz.
What the listing means
ActionAid / TACOSA appeared on the medusalocker leak site on 05 May 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 published 11 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing ActionAid / TACOSA as suspicious β leaked data gets weaponised for phishing within days.
- If you hold an account on actionaid.org, 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 β check the organisation's own disclosures before acting on it.
