Three Days Without Internet

His childhood paralleled the 1983 movie “War Games,” in which a teenager, played by Matthew Broderick, unwittingly accesses a U.S. military supercomputer. When Mr. Kaminsky was 11, his mother said, she received an angry phone call from someone who identified himself as a network administrator for the Western United States. The administrator said someone at her residence was “monkeying around in territories where he shouldn’t be monkeying around.”

Without her knowledge, Mr. Kaminsky had been examining military websites. The administrator vowed to “punish” him by cutting off the family’s internet access. Mrs. Maurer warned the administrator that if he made good on his threat, she would take out an advertisement in The San Francisco Chronicle denouncing the Pentagon’s security.

“I will take out an ad that says, ‘Your security is so crappy, even an 11-year-old can break it,’” Mrs. Maurer recalled telling the administrator, in an interview on Monday.

They settled on a compromise punishment: three days without internet.
