Transport for London (TfL) has sent out notifications to customers on Sunday evening saying that they “are currently dealing with an ongoing cyber security incident.” The government body that manages most of the transport network of United Kingdom’s capital did not provide additional details about the cyber incident, though BBC sources said that the organization’s “backroom systems at the corporate headquarters” are mainly affected. Transport for London has yet to provide an update on the situation – they promised one when the cyber incident has been resolved.
