Allium restores core services after Oct. 25 breach, revokes API keys as some features remain offline
Blockchain data provider Allium said it detected unauthorized access to some of its systems on October 25. The company notified affected customers, restricted access and hired an independent cybersecurity firm to investigate; it also revoked API keys and required customers to replace them [1] [2] [3] [4] [5].
Allium’s core services, including its App, Explorer and Explorer APIs, are back online, but some features remain unavailable. Access to uploaded data is still disabled, and the company is filling gaps in some data feeds. Allium has not disclosed the full scope of the incident [1] [2].
