As reported by Germany's Der Spiegel magazine, Volkswagen is facing serious data security problems after the travel data of 800,000 electric cars and the personal contact information of their owners were published on the internet. This data revealed sensitive details such as the exact location where cars were parked, including people's homes, private property such as government buildings, and even suspicious locations such as brothels.

Der Spiegel reported that the list of affected users included German politicians, business leaders, an entire fleet of electric vehicles used by Hamburg police, and even people believed to be intelligence agents.
The breach came to light after an anonymous hacker tipped off the Chaos Computer Club. Volkswagen has kept the data easily accessible during this time, and so far there is no evidence that anyone has misused or maliciously accessed the data.
Volkswagen did not respond to a request for comment by deadline.
