UK lawmakers are set to hold an inquiry into a cyber attack on telecoms firm TalkTalk in which the private details of over 4 million customers were put at risk.
The Culture, Media and Sport Committee said the MPs were concerned about how companies store and secure customer information online and wanted to investigate the robustness of measures put in place by telecoms and internet companies.
British police on Tuesday made a fourth arrest in connection with the attack on TalkTalk in October, which the company said had leaked the bank details of more than 20,000 customers, fewer than first thought. He was held on suspicion of Computer Misuse Act offences after officers searched an address in Norwich.
The committee said in a statement it expected to hear evidence later this month.
The company said any stolen credit or debit card details were incomplete - and therefore could not be used for financial transactions - but advised customers to remain vigilant against fraud.
