DailyQuiz

DailyQuiz operates with its headquarters located in Israel. The organization provides services that involve user accounts requiring registration with personal details. Its platform engages a substantial user base, evidenced by the scale of a cybersecurity incident impacting its systems. The company maintains an online presence accessible to international users, though specific markets served and core product offerings beyond account-based interactions are not detailed in available sources.

In January 2021, DailyQuiz experienced a significant data breach where an attacker successfully compromised its database. This incident resulted in the theft and exposure of sensitive personal information belonging to 13 million users. The stolen data included email addresses, IP addresses, and critically, 8.3 million user passwords stored in plaintext, indicating a severe failure in security practices protecting user credentials. The attacker subsequently sold this dataset through hacking forums and Telegram channels before it became publicly available. DailyQuiz acknowledged the breach via a notification on its website but provided no further substantive details regarding the attack methodology or remediation steps taken. The exposure of unprotected passwords underscored fundamental security deficiencies within the organization's infrastructure at that time.
