A cyber-attack caused major printing and delivery disruptions on Saturday at the Los Angeles Times and other major US papers, including ones owned by Tribune Publishing Co such as the Chicago Tribune and Baltimore Sun.
The cyber-attack appeared to originate outside the USA, the Los Angeles Times reported, citing a source with knowledge of the circumstance.
The attack led to supply flaws in the Saturday edition of The Times, Tribune, Sun and other papers that discuss a production platform in Los Angeles, the Los Angeles Times reported.
Tribune Publishing, whose newspapers also include the New York Daily News and Orlando Sentinel, said it detected the malware Friday.
The West Coast versions of the Wall Street Journal and New York Times were hit as they’re also printed on the shared production stage, the Los Angeles Times explained.
Tribune Publishing spokeswoman Marisa Kollias reported the virus hurt back-office systems used to publish and produce”newspapers across our properties.”
“There is no proof that consumer credit card information or personally identifiable data has been compromised,” Kollias said in a statement
Many San Diego Union-Tribune subscribers were without a paper on Saturday as the virus infected the organization’s business systems and hobbled its capacity to release, the newspaper’s editor and writer Jeff Light wrote on its website.
A spokeswoman for the Department of Homeland Security said it was studying the circumstance.
“We are aware of reports of a possible cyber incident affecting several news outlets, and are working together with our government and business partners to better understand the circumstance,” said DHS spokeswoman Katie Waldman in a statement.
