Computer virus hits Tribune Publishing, Los Angeles Times

"We believe the intention of the attack was to disable infrastructure, more specifically servers, as opposed to looking to steal information", a source told the LA Times.

The Los Angeles Times, San Diego Union-Tribune, Chicago Tribune and Baltimore Sun were among the major newspapers that had printing issues on Saturday.

All papers within The Times' former parent company, Tribune Publishing, experienced glitches with the production of papers.

"We apologize to our customers for this inconvenience", the L.A. Times said in a statement published in an article about the malware.

The news of the cyberattack was first reported by the Los Angeles Times.

While no additional details on the attack's origin were given, the source said it was the work of a "foreign entity".

Tribune Publishing discovered the presence of malware Friday that impacted some systems used to publish and produce newspapers across the company, Kollias said.

Writing about the malware attack, the Los Angeles Times explains: "Technology teams worked feverishly to quarantine the computer virus, but it spread through Tribune Publishing's network and reinfected systems crucial to the news production and printing process".

Tribune Publishing reported the attack to the Federal Bureau of Investigation on Friday, the Chicago Tribune said. "Thank you for your patience and support as we respond to this ongoing matter".

As a result, the delivery of the Saturday editions of the LA Times and San Diego Union Tribune were delayed.

Saturday editions of suburban Chicago newspapers the Lake County News-Sun and Post-Tribune will also be among those to be delivered on Sunday.

Formerly known as Tronc, Tribune Publishing also owns the South Florida Sun Sentinel, Orlando Sebtinel, The Baltimore Sun; Hartford Courant; the New York Daily News; the Capital Gazette in Annapolis, Md.; The Morning Call in Allentown, Pa.; the Daily Press in Newport News, Va.; and The Virginian-Pilot in Norfolk, Va. Tribune also products suburban newspapers in its markets.

The LA Times said that readers could access the Saturday edition online via the digital edition.

While the publications' websites weren't affected, customer service phone lines and time card systems were offline for some time.
