BERLIN — Printers at several universities across Germany produced anti-Semitic leaflets on or before Hitler’s birthday this week, after hackers appeared to break into their computer systems, according to university officials.



Universities in Hamburg, Lüneburg and Tübingen confirmed that printers connected to their computer networks had suddenly started churning out the leaflets, most of them on Wednesday, the anniversary of Hitler’s birth in Braunau, Austria, in 1889.

At least six other universities in Germany reported similar episodes, according to the German news agency DPA.

The leaflet produced at the University of Hamburg carried the slogan “Europe, awake!” and alluded to the mass migration that brought more than one million people, many from the Middle East, to the Continent last year. “Europe is being flooded by enemy strangers,” it read, in part.
