About This Breach
What information was affected in the RosaSidan incident?
The leaked member table (vld_members.csv) alongside transactional logs exposes registered subscriber profiles. The breach compromised records for 75,881 unique members, exposing:
- Account Identifiers: Member usernames.
- Contact Credentials: Canonical email addresses across Swedish domestic providers and international mail services.
- Authentication Secrets: MD5 password hashes.
- Network Telemetry: Registration and subsequent login IP addresses (ipaddress, last_login_ip_new).
- Geographic Signals: Origin login country codes (e.g., SE, NO, DK).
How many accounts were affected?
Rigorous RFC canonical parsing and deduplication confirmed 75,881 unique valid email addresses.
Technical analysis and security risks
The complete backup of the VLD Personals deployment was compromised. The exposure of user identities on adult networking platforms carries acute hazards of targeted sextortion, blackmail schemes, doxxing, and automated credential stuffing.
Recommended actions for affected users
Users who maintained accounts on RosaSidan should:
- Immediately change passwords on any active service where their community password was shared.
- Disregard and report any unsolicited extortion emails claiming knowledge of private activity.
