ECB said that attackers had managed to hack into its Banks’ Integrated Reporting Dictionary (BIRD) website, and that it is possible that the names, email addresses and position titles of the 481 subscribers to the BIRD enewsletter may have been stolen in a data breach.

The cyber-attack occurred by injecting malware into the server of an external provider hosting the BIRD website.

ECB said that it is contacting the people who may have been affected by the data breach, and that neither ECB internal systems nor market-sensitive data were affected.

The BIRD website, which provides the banking industry with details on how to produce statistical and supervisory reports, has been taken offline until further notice.
