The latest major malware attack has hampered the news production and printing processes of major U.S. newspapers.
The Los Angeles Times has reported that a computer virus that originated outside the United States has spread through the networks of Tribune Publishing.
It's the fourth largest U.S. newspaper publisher by circulation and its holdings include the Chicago Tribune and New York Daily News.
The corporation says that data of its subscribers and clients was not compromised.
The malware reportedly delayed distribution of the Los Angeles Times and San Diego Union Tribune.
It also wreaked havoc on West Coast distribution of the Wall Street Journal and New York Times, which are printed at a plant owned by the Los Angeles Times.
