For more than a month, Jaguar Land Rover hasn't built a single car. The production halt has probably cost the company millions of pounds a day. Jaguar Land Rover has not confirmed the nature of the attack, though cybersecurity experts say it was most likely an extortion-based attack, in which hackers steal data or block systems until a ransom is paid.

Cyberattacks seem inevitable lately, and large-scale theft of customer data has begun to feel almost routine. Attacks that upend company operations are exposing troubling vulnerabilities.
