Aidma Holdings: unauthorized access to the Mamaworks remote job site

Aidma Holdings investigated after the police told it that data said to be the member list of its Mamaworks remote job site had been uploaded to the internet. On 1 October it confirmed that a third party had got in through a weakness in the system's settings and that the data may be the real member list. Names, birth dates, genders, phone numbers, addresses, emails, work histories and password hashes may have leaked. The number of people was not disclosed. The weakness has been fixed.
