The hacker group "ANON_0x03" affiliated with Anonymous hacktivists has invaded the website belong to Infantry branch of Argentina Army (infanteria.mil.ar).
The website has been defaced and notified in the zone-h mirror page by a hacker with the handle "voldem0rt".
Unlike other hackers, they didn't left any messages in the defacement. They leaked the compromised database in the defacement instead.
The data leaked by Anon 0x03 includes email addresses, usernames, hashed passwords and other information.
We are still able to see the defacement page at the time of writing. But the security breach was done 24 hours ago.
