Luxury retail chain Neiman Marcus has begun to inform customers about a cyberattack it discovered in May. The attacker compromised a database platform storing customers' personal information.
The letter tells customers:
> “Promptly after learning of the issue, we took steps to contain it, including by disabling access to the relevant database platform.”
In the data breach notification, Neiman Marcus says 64,472 people are affected.
An investigation showed that the data contained information such as name, contact data, date of birth, and Neiman Marcus or Bergdorf Goodman gift card numbers. According to Neiman Marcus, the exposed data does not include gift card PINs. Shortly after the data breach disclosure, a cybercriminal going by the name “Sp1d3r” posted on BreachForums that they were willing to sell the data.

> “Neiman Marcus not interested in paying to secure data. We give them opportunity to pay and they decline. Now we sell. Enjoy!”
According to Sp1d3r, the data includes name, address, phone, dates of birth, email, last four digits of Social Security Numbers, and much more in 6 billion rows of customer shopping records, employee data, and store information.
Neiman Marcus is reportedly one of the many victims of the Snowflake incident, in which the third-party platform used by many big brands was targeted by cybercriminals. The name Sp1d3r has been associated with the selling of information belonging to other Snowflake customers.
Oddly enough, Sp1d3r’s post seems to have since disappeared.

Sp1d3r’s post count went down back to 19 instead of the 20 displayed in the screenshot above.
So, the post has either been removed, withdrawn, or hidden for reasons which are currently unknown. As usual, we will keep an eye on how this develops.
