More than 2,000 computers of many companies of the Aditya Birla group were victims of 'cryptojacking', The Economic Times reported.

This, reportedly is a new kind of cyber-warfare where the hackers misuse the terminals they are targetting and use their processing power to mine cryptocurrency and in this case, the cryptocurrency mined was Monero, which is untraceable and is known for huge price volatility.

The attack was first noticed last month at the group's subsidiary abroad, the report said. “It’s a kind of attack where the primary intention of the hackers is not to steal information and cause business disruption. Rather, they hijack the target’s computers and tap the power supply to the organisation to mine crypto coins,” a person aware of the attack told the paper.

“Aditya Birla Group has advance threat management systems that are constantly monitoring and protecting business critical applications and infrastructure in all Businesses. Recently, the advance threat detection systems of our Group alerted us of suspicious activity on some desktop systems. Based on this, our internal team immediately carried out an investigation and deployed countermeasures to isolate and eliminate the cause of this activity," a spokesperson told the paper on Thursday.
