E-commerce site eBay has urged its users to change their passwords after the website's database, which contained names and contact details of customers, was compromised by hackers.
In a statement eBay insisted that there was "no evidence that financial information was accessed."
ITV News' Consumer Editor Chris Choi reports:
Michela Menting, cybersecurity director at technology market experts ABI Research has suggested that hackers gained eBay credentials through "social engineering," a type of psychological manipulation to get people to divulge confidential information.
Menting said: "Finally I think their timely public announcement - two weeks after discovery - helps to reassure not only public opinion, but also their own brand reputation.
"Transparency when dealing with incident response for an event that has affected customers, in this case millions, is highly commendable - it means that eBay takes security seriously."
PayPal have said in a statement that "extensive forensic research" has shown "no evidence of unauthorized access or compromise to personal or financial information for PayPal customers."

They also stated that PayPal never shares financial information with merchants, "including eBay" and that it encourages any eBay user who used the same password on other sites to change those too.
In a statement on the eBay website, the company has said it has "no evidence of the compromise resulting in unauthorised activity for eBay users."
They also said that there has been "no unauthorised access to financial or credit card information which is stored separately in encrypted formats".

The firm did reiterate that changing passwords is a "best practice and will help enhance security for eBay users".
Cyber attackers have accessed eBay customers' names and contact details, the company said in a statement.
eBay said: "The database, which was compromised between late February and early March, included eBay customers’ name, encrypted password, email address, physical address, phone number and date of birth.
"However, the database did not contain financial information or other confidential personal information."
The online auction site said evidence of the hack was first detected about two weeks ago, but it was now making the announcement after "extensive forensics".

Cyberattackers hacked employee log-in credentials, allowing them access to the company's corporate network.
Tests so far show no evidence of unauthorised activity by users or access to financial or credit card information, eBay said.

The paper said the purported Holocaust artefact had been priced at £11,300 by the eBay vendor, a Ukrainian man based in Canada, who had sold another batch of clothing purporting to be linked to Auschwitz for £11,300 pounds last year.
Other items reported to be for sale included shoes and a toothbrush belonging to a death camp victim and Star of David armbands used to mark out Jews for persecution.
The newspaper said eBay had been unable to say how long such items may have been for sale on its website.
EBay has apologised after memorabilia from the Holocaust was found for sale on the site.
The company, which receives a commission on items sold and charges vendors a listing fee, released a statement saying:
We are very sorry these items have been listed on eBay and we are removing them. We don't allow listings of this nature, and dedicate thousands of staff to policing our site and use the latest technology to detect items that shouldn't be for sale.
We very much regret that we didn't live up to our own standards. We have made a donation to charity to reflect our concern.
