Home Chef, a US-based meal kit and food delivery service, announced a
data breach today after a hacker sold 8 million user records on a dark
web marketplace.

Last week, BleepingComputer reported that a hacking group actor named
Shiny Hunters was selling the user records for eleven companies on a
dark web marketplace. The threat actor was selling these databases for
$500 to $2,500.

The user records for Home Chef was one of the databases being sold and
allegedly contained 8 million user records.

four digits of their credit card, gender, age, subscription
information, and more.

never received a response.

Home Chef issues data breach notification

Now, almost two weeks later, Home Chef has officially disclosed the
data breach in a "Data security incident" notice posted to their web
site.

"Protection of customer data is a top priority for Home Chef, and we
work hard to safeguard our customers’ information. We recently learned
of a data security incident impacting select customer information,"
their data security incident FAQ states.

According to this notification, Home Chef states that a customer's
email address, name, phone number, encrypted passwords, the last four
digits of credit card numbers, and other account information were
accessed.

Home Chef states that only the last four digits of a customer's credit
card was accessed and that they do not store complete payment
information in their databases.

In a statement to BleepingComputer, Home Chef confirmed that this data
breach notification is related to the database that was being sold
online.

What Home Chef customers should do

While the passwords leaked in this data breach were encrypted, threat
actors can use programs to decrypt the password.

Therefore, if you are a Home Chef customer, you should immediately
change your password to a strong and unique one.

If that same password was used at another site, you should change it
at any other site that also uses it.

When changing your passwords, be sure to use a unique and strong
password at every site so that a data breach does not affect your
account at other companies.
