According to Yahoo News
, the hackers replaced a memorial "book of the dead" at Buchenwald's website with threatening comments.
Volkhard Knigge, who runs the Buchenwald Memorial Foundation, had naturally, strong words for the perpetrators of the cyber-crime, stating the "By damaging the services and documentation that we offer -- such as the Book of the Dead at Buchenwald concentration camp -- the perpetrators were trying to efface the memory of the victims of the crimes of the Nazis."
Around 250,000 interned individuals at Buchenwald, most of them of Jewish heritage, were killed during World War II.
Another camp, Mittlebau Dora, also suffered a similar online break-in, where hackers completely erased their memorial site.
At the Buchenwald website, eerie slogans such as "We'll be back" briefly emblazoned the walls of the once hallowed memorial.
German police are currently investigating the crime.
