In a security breach dubbed a “recipe for an attack,” a public government website has posted an official document outlining plans to bomb-proof a new Department of Defense building, Reuters reports.
The document includes a narrative and hundreds of pages of technical data describing the bomb resistance strategy for the Mark Center, a Pentagon annex in Alexandria, Va., where about 6,400 personnel are slated to move this year.
Although each of the document’s 424 pages is stamped “For Official Use Only,” Reuters on Wednesday discovered a copy of the report on a website maintained by the Army Corps of Engineers. “Even after the Pentagon said the document had been taken down from the public website,” the news service says, “a version could still be accessed in a Google cache.”
The document is a “recipe for an attack,” according to former Justice Department lawyer Michael Greenberger, because it would allow potential threats to pinpoint weaknesses in the building’s infrastructure.
