App-maker Touchnote has become the latest victim of internet hacking.
The online company, which has an app that lets people turn photos on their mobiles into postcards, said it had been targeted by criminals and some customer data had been stolen.
The stolen details include customer names, email addresses and postal addresses, while there were also "some recorded instances of dates of birth being accessed", the company said.

Nicola Perry said that Daniel, 17, was left traumatised by the ordeal. She added:

Inquiries by detectives from Police Scotland revealed an electronic online trail, which led to the Philippines and links to organised crime groups there. More than 50 people have been arrested in a series of raids, according to Philippine authorities in an operation codenamed Strikeback.

However, CAB said the real figure was likely to be much higher because a lot of fraud goes unreported.
Tens of millions of UK email users may be having their financial details stolen in a "mass spamming event," according to experts in cyber crime.
The National Crime Agency warned that small and medium businesses are the top targets of the messages that appear to be legitimate emails from banks.
The emails come with attachments that appear to be files containing details of a suspicious transaction, but in fact harbour malicious software.
The screen will then display a countdown timer that demands the payment of 2 Bitcoins (around £536) - a form of currency used for Internet transactions - in ransom for the decryption key.
The National Cyber Crime Unit advises that anyone whose computer is infected should report it to www.actionfraud.police.uk.
Crime is changing and not falling at the rate that figures suggests, the chairman of the Police Federation of England and Wales said today, after an influential group of MPs found that UK was "losing the war against cyber crime" in a new report.
