A breach of Adecco's candidate database, containing Cassandra (CQL) database dumps from their 'aecandidatos' system. The exposed data includes candidate records with names, email addresses, hashed passwords, country information, job application history (avisos_postulados), and saved job listings (avisos_guardados). The keyspace 'aecandidatos' suggests this is Adecco's Latin American candidate portal. Data was shared on BreachForums.
