Transport for London faces ‘ongoing cyber security incident’

Transport for London’s (TfL) computer systems have been targeted in an ongoing cyber attack.

It said there was no evidence customer data had been compromised and there was currently no impact on TfL services.

Insiders have told BBC London they have been asked to work at home if possible, and that it is the transport provider’s backroom systems at the corporate headquarters that are mainly affected.

TfL’s chief technology officer Shashi Verma said: “We have introduced a number of measures to our internal systems to deal with an ongoing cyber security incident.”

He added: “The security of our systems and customer data is very important to us and we will continue to assess the situation throughout and after the incident.

“Although we’ll need to complete our full assessment, at present there is currently no evidence that any customer data has been compromised.

“There is currently no impact to TfL services and we are working closely with the National Crime Agency and the National Cyber Security Centre to respond to the incident.”
