“We would like to clarify that the incident did not impact the Company's ongoing critical business operations. It is further submitted that this information would not fall under the category of developments to be notified under Regulation 30 of SEBI,” the company said in a press note to the exchanges on Friday.
The company became aware of a potentially abnormal activity within its network about 10 days ago in respect of few of its employee accounts, who were subjected to an advanced phishing campaign, the company said.
On Friday, financial markets were shut on account of Good Friday.
"Upon learning of the above, the company promptly kicked off its standard operating procedure for addressing such incidents. We began investigating the incident, identified and isolated the employee accounts which were impacted, took remedial steps to contain the incident and mitigate any potential effects of the incident, Wipro added.
"The company also informed the handful of customers where the affected employees are engaged. Like any large enterprise, the company investigates over 4.8mn alerts in a year,” said Wipro.
The company has used its industry leading Cyber Security practices and partner ecosystem for remedial steps and has shared this intelligence with its partners to develop the AntiVirus signatures.
