Breach Intelligence Summary
Entity: Bitly · Actor: Unknown · Sources: 11 references
Attack: Database Exposure
Profile: Platform · URL shortening and link analytics · SaaS link management platform · Global
Timeline: Breach (2014-05-08) · Indexed (Dec 01, 2024) · Year (2014)
Exposure: 9.3M records · 3 fields: Email Address, Password, Username
Status: Confirmed
Executive Summary
In May 2014, link-management company Bitly disclosed a breach after attackers accessed a backup database, exposing 9,316,204 accounts. Exposed data included email addresses, usernames, and password hashes, most using SHA-1 with a small number using bcrypt.
ObscureIQ assessment: Exposure enables phishing, brand impersonation, and abuse of analytics or campaign data. Short-link history can also reveal business relationships, tracking strategies, and user behavior.
Breach Impact
The SHA-1 hashes are crackable, exposing reused credentials to stuffing; Bitly’s forced reset limited direct account-takeover on its own platform.
