According to a recent article from The New York Times, the Saturday edition of some newspapers across the U.S. didn't go out as planned due to a computer malware attack that hindered the plant responsible for printing the editions.
The New York Times reported:
The malware was focused on the networks used by Tribune Publishing, which until recently owned The Los Angeles Times and The San Diego Union-Tribune. The two papers still share their former parent company’s printing networks.
The Los Angeles Times said the attack also affected the Saturday distribution of The New York Times and The Wall Street Journal, which share use of a large printing plant in Los Angeles for their West Coast editions. Both appear to have been collateral damage; there was no evidence that they were hit by the same malware aimed at the Tribune company.
