CHARLOTTESVILLE, Va. — The Southern Environmental Law Center is warning people not to open or click on links in any email referencing a SELC security failure.

The center has been the victim of a major internet security breach in which highly confidential information was stolen, according to a news release from spokeswoman Kathleen Sullivan. The FBI has been notified, Sullivan said.

The SELC is a regional nonprofit that addresses health and environmental concerns in Virginia, Tennessee, North Carolina, South Carolina, Georgia and Alabama.

“We believe this was done intentionally as an attempt to undermine SELC’s mission,” Sullivan said.

The center advises anyone receiving suspect emails from the agency to immediately delete them.
