The American Association for the Advancement of Science has taken down its scientific press release website because of a “serious security breach.”

The AAAS posted an advisory on its website saying it was acting out of an abundance of caution.


“The integrity of content on our website is of the utmost concern to us,” the association said as it addresses “a serious security breach.”

The AAAS said it became aware of the situation Monday, two days after the breach that compromised usernames and passwords. The hack resulted in the early release of an embargoed EurekAlert! press release and the site was taken down to protect other embargoed material.

“Please be assured that financial information from subscribing institutions is not stored on the EurekAlert! website and therefore remained secure,” the advisory said.
