Bookoff and JR East report possible leaks affecting over 6 million accounts each

Bookoff and JR East both reported possible leaks of customer information after unauthorized access to computer systems.

Bookoff said data linked to up to 6.43 million accounts may have been exposed, while JR East reported about 6.09 million accounts.

The exposed information varies, and neither company reported that all types of customer data were affected.

Such information can put customers at risk, so the companies are investigating and say security needs attention.
