Reported by CALIFORNIA AG filing
Imgur disclosed a 2014 data breach in a 2017 notification. An unauthorized third party stole user account data (email and password). Passwords were cracked via brute force using an older SHA-256 hashing algorithm. Imgur required password resets and updated to Bcrypt. No specific affected individual count was provided in the filing.
About this clustering
DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
