Bus services at London’s biggest operator Go-Ahead are under threat after the company was hit by a “cyber security incident”.
Bus and driver lists are understood to have been among the areas targeted by the apparent hackers on Monday.
Any service delays will be posted on the relevant Twitter account, a spokesperson told Sky News.
Go-Ahead, which is also a major player in other cities including Brighton and Newcastle, said the incident was ongoing.
Their statement read: “Go-Ahead announces that it is currently managing a cyber security incident after detecting unauthorized activity on its network on Monday, September 5, 2022.
“Upon learning of the incident, Go-Ahead immediately engaged external forensic experts and has taken precautionary measures with its IT infrastructure as it continues to investigate the nature and scope of the incident and implements its response plans to incidents
“Go-Ahead will continue to assess the potential impact of the incident but confirms that there is no impact on UK or international rail services operating as normal.
“As a precaution, Go-Ahead has notified the relevant regulators, including the Information Commissioner’s Office in the UK.”
Go-Ahead London is the capital’s largest bus operator, with over 2,400 buses.
The company said later on Tuesday that it had managed to avoid disruption to passengers so far and expected to run a normal service on Wednesday.
