Russian criminal gang Cl0p has taken responsibility for the breach, which saw it initially hit payroll software company Zellis using a vulnerability in the MOVEit Transfer file transfer software. Cl0p claims hundreds of businesses have been exposed in the breach. > Cl0p used the MOVEit Transfer vulnerability to access information on Zellis servers. The company supplies payroll services to a host of big name clients, including BA, the BBC, Boots and a third of the FTSE 100. As a result, records on hundreds of thousands of employees of at least eight businesses that work with Zellis have fallen into the hands of hackers.
