Status: Confirmed
Executive Summary
In early 2019, the Japanese schedule/notebook app Lifebear appeared for sale on a dark-web marketplace, exposing about 3.67 million unique email addresses along with usernames, dates of birth, and passwords stored as salted MD5 hashes.
ObscureIQ assessment: Risk is moderate to high because productivity apps can expose more than login data. Even when the breach does not include full calendar contents, the service context implies possible access to routine, planning, and behavioral data that can support phishing, profiling, or targeted social engineering.
Breach Impact
Salted MD5 is crackable, exposing reused credentials; DOB adds profiling value.
