About This Breach
Originally surfaced via Telegram channels, the parsed records were subsequently disseminated across dark web hacking communities in 2026.
What information was affected in the Daryn Online incident?
The leaked student and parent dataset (Daryn [daryn.online] (Parsed) 2023 - 4.20M.csv) encompasses official academic rosters spanning from 2011 through 2023 across schools nationwide. The breach compromised records for 3,900,214 unique verified students and parents, exposing:
- Personal & Fiscal Identifiers: Full legal names, dates of birth, and Kazakh Individual Identification Numbers (IIN).
- Contact Credentials: Canonical email addresses and active mobile telephone numbers.
- Academic & School Records: Full official name of the educational institution, regional school district, grade level, and year of admission.
- Geographic Telemetry: Administrative regions, cities, and oblasts across Kazakhstan.
How many accounts were affected?
Strict RFC canonical validation and deduplication confirmed 3,900,214 unique valid email addresses across 4,209,062 total student roster entries.
Technical analysis and security risks
Exposing minors' full names, official school institutions, and parent contact information alongside national identification numbers represents a severe privacy failure. Threat actors can weaponize these records for extortion, spear-phishing campaigns masquerading as school administrations or exam boards, and identity fabrication.
Recommended actions for affected users
Students and parents registered with Daryn Online should:
- Immediately update passwords for Daryn Online and any linked email accounts.
- Maintain heightened vigilance regarding unsolicited communications soliciting fees for exams, school transfers, or tutoring programs.
- Implement multi-factor authentication (MFA / 2FA) across all digital education and communication platforms.
