London Transport System says no customer data was compromised in Sunday's hacker attack

Transport for London (TFL) has issued a notice informing Londoners that hackers have penetrated the transport system's IT network, but have not stolen any customer data and caused only minor damage.

“We are currently dealing with an ongoing cybersecurity incident,” said the cybersecurity incident notice posted on the TFL.gov.uk website. “There is currently no indication that customer data has been compromised and there has been no impact on public transport.”

“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,” the statement continued. “We are working closely with the appropriate government authorities to respond to the incident.”

While it is expected that operations on the public transport network will largely continue as normal, TFL has taken some “proactive measures” to protect the integrity of its services and data.

These efforts mean:

● Live Tube arrival information is not available on some digital channels

● Applications for Oyster photo cards, including Zip cards, have been temporarily suspended

● Customers who pay in advance using contactless payment will temporarily not be able to access their online trip history.

● No refunds are possible for journeys made with contactless cards.

● Oyster customers must serve themselves online

● Employees have limited access to systems and email, meaning communications may be delayed or temporarily unavailable.

In a statement provided to BleepingComputer, TFL's Chief Technical Officer Shashi Verma underlined TFL's stance on the incident, saying: “Customer data is very important to us.”

So far, there is no indication that the attackers stole data from TFL's servers. However, it cannot be ruled out that some data will be lost as a result of this breach, as is often the case with ransomware attacks – if this is what it is.

If you are a TFL customer, beware of unsolicited messages asking for your input – for example, to confirm a login or instructions to share personal information. Fraudsters typically use data stolen in security breaches to conduct social engineering attacks on internet users.

Anyone affected by a data breach should consider using a data monitoring service. Bitdefender Digital Identity Protection This will help you find out if your data has been leaked online, what type of information has been compromised, what risks you face, and if your information is for sale on the dark web.

Bitdefender recently published two simple guides explaining how good cybersecurity hygiene can help combat the rising tide of social media scams targeting ordinary citizens.
