Cyber security experts at Google have estimated that more than 100 companies may have been affected by a sophisticated hacking campaign targeting Oracle. Speaking to new agency Reuters, Google analyst Austin Larsen said the initial assessment indicates that the damage from the operation could be significant.

The tech giant revealed in a statement that the hackers had stolen a considerable volume of customer data. According to Google, the attackers may have started as early as three months ago. The substantial resources the hackers invested in reconnaissance prior to the attack point to a high level of planning and investment.

Google’s blog post notes that the alleged perpetrator of the attack, a hacking group known as CL0P, has a history of compromising third-party software and service providers on a large scale. Analysis by Google analyst Austin Larsen indicates that dozens of victims have been identified so far, but the actual number is likely much higher. Based on the scale of previous CL0P campaigns, it is estimated that over a hundred companies may have been affected.
