HCLTech denies system breach after hacker claims employee data theft
Some computer hackers said on a secret part of the internet that they had stolen information about people who work at a big tech company called HCLTech.
The hackers said they had details like workers' names, email addresses, and phone numbers, and that they wanted to sell that information.
HCLTech is a company in India that helps other companies with their computers.
The company looked into the claim and said the information might be from a few years ago.
HCLTech also said its own computer systems were not broken into.
The company said it did not find any proof that the systems it uses to help its customers were in danger.
The hackers said they got the information from a special cloud service made by Microsoft.
HCLTech does not agree with the hackers and says its systems are safe.
HCL Technologies responded to a hacker group's claim that it accessed employee data, saying the allegedly stolen data may be limited and dated to a few years back.
In an exchange filing on Monday, August 10, HCLTech denied that there has been a breach of its internal systems.
The company said it found no evidence that its client engagement systems were compromised.
A threat actor on a dark web forum claimed to be selling a dataset of over 250,000 employees, including names, email addresses, job titles, departments, phone numbers, physical addresses, and employee and service account records.
The hacker claimed the dataset was obtained from a Microsoft Azure Tenant using compromised credentials.
