TfL restricts access to online services due to cyber attack

The organisation, which is responsible for most of London's transport network, said it was preventing passengers from viewing their journey history for journeys paid for with contactless cards.

In addition, access to some live travel information services via apps and the company's own website is restricted.

These include train updates and TfL JamCams, which typically show live feeds of traffic on main roads.

In addition, TfL has restricted access to the photocard portal, through which customers can apply for travel concessions.

The booking system for the door-to-door minibus service “Dial a Ride” became unavailable earlier this week.

TfL said essential bookings could now be made by phone and hopes to be able to offer full service again “in the coming days”.

Shashi Verma, TfL’s Chief Technology Officer, said: “The security of our systems and customer data is very important to us.

“We continuously monitor who accesses our systems to ensure that only authorized people have access.

“We detected suspicious activity on Sunday and took steps to restrict access.

“A thorough investigation is currently underway and we are working closely with the National Crime Agency and the National Cyber ​​Security Centre to respond to the incident.

“Internal access restriction measures remain in place and there continues to be no impact on our public transport and no indication that customer data has been compromised.

“We will continue to keep our customers and staff updated on the incident as part of this ongoing work and thank them for their patience while we respond to this incident.”
