CBI sources said they had inputs from the US probe agency on the activities of Amit Vikram Tiwari, son of a senior army officer. He was arrested for alleged violation of the Information Technology Act.
The sources said 30-year-old Tiwari was allegedly working for his clients through two web sites-- www.Hirehacker.Net and www.Anonymiti.Com-- with servers located in the US offering services of illegally accessing passwords of email accounts in exchange for a fee varying from USD 250-500.
They said during initial questioning, it has surfaced that Tiwari allegedly hacked into 900 email accounts between February 2011-2013, of which 171 were Indian victims. The clients varied from individuals to corporates.
CBI sources said they are still probing whether national security was compromised by Tiwari's acts.
