A statement posted on its website said: “We are currently dealing with an ongoing cyber security incident.
“At present, there is no evidence that any customer data has been compromised and there has been no impact on TfL services.
“The security of our systems and customer data is very important to us, and we have taken immediate action to prevent any further access to our systems.
“We are working closely with the relevant government agencies to respond to the incident.”
Shashi Verma, TfL’s Chief Technology Officer, said: “We have introduced a number of measures to our internal systems to deal with an ongoing cyber security incident.”
“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,” he added.
