Executive Summary

In January 2021, the quiz website Daily Quiz (dailyquiz.me) suffered a data breach exposing details for ~12.8 million users, including ~8.3 million email addresses with plaintext passwords, plus usernames and IP addresses. The stolen data was sold on hacking forums and Telegram channels for around $2,000 before leaking into the public domain and being added to Have I Been Pwned. Plaintext storage makes the credentials immediately usable for credential stuffing. Threat actor and intrusion method are not reliably established.

ObscureIQ assessment: Exposure enables phishing, account abuse, and profiling based on quiz behavior and interests. Quiz-response data may also reveal demographic, political, or lifestyle signals.

Breach Impact

Because passwords were stored in plaintext, the exposure of emails, usernames, IP addresses, and passwords enables immediate credential-stuffing and account-takeover on any service where users reused those passwords, with no cracking required. Targeted phishing is also enabled.
