Production of newspapers owned by Chicago-based Tribune Publishing was disrupted after malware began infecting the company's publishing and printing systems. Tribune newspapers report that they appear to have been hit by crypto-locking Ryuk ransomware.
Don't rush to blame the printing outage at newspapers owned by Tribune Publishing on anything more than an organization failing to block a malware outbreak.
