Data compromised

Actor listing claims 1.5M+ records with limited technical detail — data types not independently evidenced; Obsidian had not confirmed

Technical writeup

Unverified leak-site / forum claim — July 25, 2026. Daily Dark Web reported a listing claiming a database of more than 1.5 million records associated with Obsidian (Obsidian.md note-taking / knowledge-management app). The post provided limited technical detail and no public sample to independently verify authenticity. Obsidian had not publicly confirmed a breach at indexing time. Community commentary noted Obsidian’s local-first architecture, which makes a centralized “full vault dump” less typical than account/contact-style datasets — treat the claim as unverified until the vendor or reputable forensic reporting corroborates it.

Root cause

Unverified dark-web forum listing claiming 1.5M+ Obsidian-associated records; no public samples cited
