Hackers created a traffic jam in Moscow on Thursday by ordering dozens of taxis from the ride-hailing app Yandex Taxi to converge on the same location in one of the first known instances of attackers using an app-based taxi company to create chaos on the roads.

Video circulated on social media showing a very long traffic jam of taxis along an otherwise lightly trafficked road. The video was then shared by the account @runews where it was retweeted more than 6,500 times as of this writing.
