Early reports are that it was a type of ransomware. Apparently it hit an LA Times printing facility, which disrupted other papers that shared that production facility. Anonymous reports say that it was the Ryuk malware, which is typically used by a criminal group that targets organizations that are very sensitive to downtime. Bring the printing press to a halt and demand money to restore service. Not a bad trick.
There’s no solid evidence yet that this was a state sponsored attack, or politically motivated. My money is on plain old crooks, until more information comes out.
