PRINCETON, N.J. — A well-known computer hacker who goes by the name of “Weev” said he was behind a wave of anti-Semitic, racist fliers that appeared on printers at more than a dozen college campuses last week.

Covered in swastikas, the fliers, which seemed to appear spontaneously on printers, including those at Princeton University, mentioned “the struggle for global white supremacy.”

Weev is the alias of Andrew Auernheimer, who in 2010 was part of a group of hackers that discovered a security loophole on AT&T’s servers and gained access to the data of 114,000 customers. Mr. Auernheimer was initially convicted of identity fraud and conspiracy to access a computer without authorization, but his conviction was overturned on appeal.

Mr. Auernheimer said in an interview on Monday that he sent the fliers to every publicly accessible printer in North America. He said he did not specifically target college campuses.
