On April 14 , the company disclosed to the California attorney general that a December 2015 breach Attack.Databreach compromised Attack.Databreach more sensitive information than first thought .

The dual notifications mark the latest problems for the company , which disclosed in early 2014 that its payment systems were infected with malware that stole Attack.Databreach 350,000 payment card details . Over the past few years , retailers such as Target , Home Depot and others have battled to keep their card payments systems malware-free ( see Neiman Marcus Downsizes Breach Estimate ) . The 2015 incident started around Dec 26 . In a notification to California about a month later , the retailer said it was believed attackers cycled through login credentials that were likely obtained Attack.Databreach through other data breaches Attack.Databreach . A total of 5,200 accounts were accessed Attack.Databreach , and 70 of those accounts were used to make fraudulent purchases . Although email addresses and passwords were not exposed Attack.Databreach , the original notification noted , access Attack.Databreach to the accounts would have revealed names , saved contact information , purchase histories and the last four digits of payment card numbers . The affected websites included other brands run by Neiman Marcus , including Bergdorf Goodman , Last Call , CUSP and Horchow .

The breach Attack.Databreach exposed Attack.Databreach names , contact information , email addresses , purchase histories and the last four digits of payment card numbers . It did n't specify the number of accounts affected . The attackers were also able to access Attack.Databreach some InCircle gift card numbers , the company says . Web services can slow down hackers when suspicious activity is noticed , such as rapid login attempts from a small range of IP addresses . Those defensive systems can be fooled , however , by slowing down login attempts and trying to plausibly geographically vary where those attempts originate . For those affected by the January incident , Neimen Marcus Group is enforcing a mandatory password reset . It 's an action that 's not undertaken lightly for fear of alienating users , but it 's a sign of how serious a service feels the risk is to users or customers . The company also is offering those affected a one-year subscription to an identity theft service .
