California Pizza Kitchen Suffers Data Breach, SSN of 100k Individuals Exposed
The Impacted People Are Former and Current Employees of California Pizza Kitchen.
The US pizza chain California Pizza Kitchen (CPK) allegedly suffered a data breach that exposed the names and Social Security Numbers (SSNs) of over 100,000 current and former employees.
What Is California Pizza Kitchen?
Founded in 1985, California Pizza Kitchen (CPK) is an American casual dining restaurant chain that specializes in California-style pizza.
According to Wikipedia, the chain has over 250 locations in 32 U.S. states, and ten other countries, including 15 California Pizza Kitchen nontraditional franchise concepts designed for airports, universities, and stadiums.
When Did the Breach Happen?
According to a data breach notification, the incident occurred on September 15th when the company observed a disturbance on its systems. As per the notice, the number of persons affected (including residents) has reached 103767.
The pizza chain declared that it took immediate action in order to mitigate and investigate the attack with the help of third-party IT specialists.
The impacted individuals received a notice from CPK stating:
CPK immediately secured the environment and … launched an investigation to determine the nature and scope of the incident.
Although the attack was discovered on September 15th, it wasn’t until October 4th that the chain was able to determine threat actors had managed to obtain access to the company’s systems.
What Data Was Exposed?
According to California Pizza Kitchen, the cyberattack had delivered threat actors the Social Security Numbers (SSNs) of former and current employees, as well as names and other confidential files. Fortunately, there is no evidence that the data obtained was misused by attackers.
There are no details on what kind of breach impacted the pizza chain or how cybercriminals gained access to the network.
At the moment, the firm is analyzing existing security policies and has put into practice supplementary security measures, such as safeguards and staff training, to help prevent similar situations in the future.
The Importance of Employee Training
According to security experts, employee training is a critical factor in preventing breaches like this, which are becoming more common in companies that store private information on their networks. The problem is that these companies frequently hire people without specific knowledge of how security breaches can happen.
Every business like California Pizza Kitchen possesses valuable PII data which makes them a prime target for attackers. To help protect against attacks, enterprises need to ensure their employees practice good cybersecurity hygiene.
The CPK data breach comes after another major data breach from investment platform Robinhood. After their systems were compromised, a threat actor acquired access to the personal information of around 7 million consumers.
Following the Robinhood data breach disclosure, a cybercriminal known as pompompurin’ posted on a hacking forum that the stolen information is available for sale.
Just like many other businesses, California Pizza Kitchen (CPK) had a really hard time during the pandemic. The organization filed for chapter 11 bankruptcy in July 2020 in an effort to reduce its debt.
