Breach 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.

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.

Exploitation & Downstream Threats

• Immediate credential stuffing and account takeover (plaintext passwords, no cracking needed) | • Targeted phishing using exposed emails | • Cross-platform account compromise via password reuse

Principal Risk Advisory

What this means for a principal

A consumer-service breach: contact and account data supports phishing, account takeover and profile enrichment. For a high-profile principal the main risk is credible impersonation and enrichment of existing exposure.

What You Should Do

  1. Reset any reused passwords and enable MFA on email first, then financial accounts.
  2. Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.

How ObscureIQ Can Help

  1. Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
  2. Exposure mapping: cross-reference the exposed identifiers against broker-available data to size and prioritize the principal's wider footprint.
  3. ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
