Data containing 10k unique email addresses and a smaller number of names and phone numbers was subsequently leaked. A threat actor claiming responsibility for the breach alleges to have additional, more sensitive data including screenshots, VPN configuration files, credentials, source code, certificates, archives, and SQL backup files.
