Zynas: cyberattack on Joyfull's HR contractor

On 29 January, Zynas, which handles work for the Joyfull restaurant chain, found that a server it had set up to pass data to a subcontractor had been accessed and part of its database deleted. Data on 23,585 Joyfull employees, job applicants and their family members may have leaked, from interview and hiring documents: names, addresses, birth dates, medical history, salary accounts and more (the number of people differs by item).
