Calssara
Calssara is a cybercrime threat actor associated with the initial sharing/leak (May 2022) of a dataset of Instagram account information later recirculated by other actors. According to Kela, the dataset later leaked by “Solonik” (17.5M accounts) was identical to the dataset first shared by Calssara in May 2022 and subsequently leaked again by “vanz” in June 2023 (BreachForums). The dataset is described as legitimate but old and contains Instagram-related account/profile data including usernames and, in some records, email addresses and phone numbers (and is also described as including physical addresses), but it does not contain passwords. The primary risk from this dataset is enabling targeted phishing and social engineering rather than direct account compromise.
