Calssara is a cybercrime forum handle associated with the publication of a large Instagram-related dataset first shared in May 2022. The dataset was later assessed by researchers as old scraped data that was subsequently rebranded and recirculated by other forum actors as if it were a new leak. Available reporting ties Calssara to the initial sharing of the dataset, which contained public Instagram profile information and, for a subset of records, contact details such as email addresses and phone numbers. There is no high-confidence evidence that the dataset included passwords or that Calssara compromised Instagram systems directly. The activity is consistent with criminal handling and dissemination of scraped platform data that can support downstream phishing, social engineering, and account-targeting operations. No reliable attribution to a nation-state, formal intrusion set, or broader sub-group structure is currently available.
