The Bengaluru-based company, which is scheduled to announce its fourth quarter financial results later in the day, said it has also retained an independent forensic firm to assist the company in its investigation of the matter.
Cybersecurity blog KrebsOnSecurity had said that Wipro's systems had been breached and were being used to launch attacks against some of its clients.
Upon learning of the incident, Wipro promptly began an investigation, identified the affected users and took remedial steps to contain and mitigate any potential impact, it added.
Wipro pointed out that it is leveraging its cyber-security practices and collaborating with its partner ecosystem to collect and monitor advanced threat intelligence for enhancing security posture.
"We have also retained a well-respected, independent forensic firm to assist us in the investigation. We continue to monitor our enterprise and infrastructure at a heightened level of alertness," it added.
KrebsOnSecurity cited sources to state that Wipro was "dealing with a multi-month intrusion from an assumed state-sponsored attacker" and that Wipro's systems were seen being used as jumping-off points for digital fishing expeditions targeting at least a dozen Wipro customer systems.
