IT major Cognizant has confirmed that some of its employee’s personal data was compromised during a Maze ransomware attack in April.
The data included names and account numbers of company corporate credit cards, the company said in an email to employees, which Moneycontrol has seen.
Cognizant was attacked by Maze ransomware on April 18, which caused disruptions to its clients. During its recent result announcement, the company said that it expects the impact to be in the range of $50-70 million in revenue and margins for the quarter ending June 30, 2020.
The ransomware encrypts the sensitive information, in this case, employee credit card account numbers, and exfiltrates these to the hackers.
In the email to employees, Cognizant said, “A limited amount of personal data (of associates) was compromised before the attack was contained on May 1.”
“Vast majority of the information consisted of names and account numbers (and no other personal information) from some American Express cards,” the mail added.
The email further added that some of its associates who held corporate credit card will have access to complimentary credit card monitoring, dark web monitoring, and restoration services. This will be available to everyone whether or not their card data was compromised in the attack.
The company has also identified a limited number of instances where other personal data may have been compromised. “The small number of associates who have had other kinds of personal information exposed will be notified directly by June 24, 2020, and will also receive complimentary identify theft protection,” the company added.
According to CRN, the company has filed two letters with California state regulators where it has disclosed the theft of personal information related to company credit cards.In another email sent to employees impacted, the company has said that personal information compromised included social security number, tax identification number, financial account information, driver’s licence information, and passport information, the CRN report added.
