A cyberattack originating from outside the United States disrupted The Los Angeles Times' printing and delivery for many of its print editions Saturday, according to the newspaper.
The virus caused production problems at various newspapers across the country, along with the California Times printing plant in downtown Los Angeles, where the Times is printed, the paper said.
Along with the Times, California newspapers affected by the apparent attack included the San Diego Union-Tribune, Chicago Tribune, Baltimore Sun and several major newspapers that share the production platform, according to the newspaper.
The Southern California editions of the Wall Street Journal and The New York Times were affected as well.
The Times said the company "is investigating whether the computer problems were the result of a cyberattack by a third party," sources with knowledge of the situation said, according to the Times.
The Times said the issue -- which apparently began late Thursday night -- was first detected Friday. Technology teams made significant progress in fixing the problem, but were unable to clear all systems before press time.
Distribution director Joe Robidoux said he expects the majority of Times subscribers would receive their paper later Saturday. Those who don't will get it with their regularly scheduled delivery of the Sunday edition.
