Timeline: Breach (2019-08-21) · Indexed (Nov 11, 2019) · Year (2019)

Status: Confirmed
Executive Summary
On 21 August 2019, the comic-creation site ToonDoo was breached and the database was redistributed on a hacking forum in November 2019, exposing 6,002,694 records. Impacted data included email addresses, usernames, genders, salted password hashes, and in some cases IP addresses and geographic location (city and country).
ObscureIQ assessment: Exposure enables account takeover, phishing, and leakage of creative projects. If school use is involved, student identities and classroom-linked activity may also increase sensitivity.
Breach Impact
The credential and location data supported credential-stuffing and geographically targeted phishing against a user base that skewed toward students and educators.

Why They Hold Your Data
