The Outsourcers Answer: TCS and HCLTech Confront a Hacker’s Claims

India’s two largest IT services firms spent two days responding to a hacker group’s claims of stolen employee data. Tata Consultancy Services told exchanges it found no credible evidence of a breach of its systems or customer environments, and described the referenced data as more than four years old. HCLTech filed a near-identical statement a day later. The attacker claims password spraying and multifactor fatigue as the way in, and reportedly holds records on more than 250,000 HCLTech staff drawn from a Microsoft Azure tenant. Between them, the two firms run technology for thousands of the world’s largest organisations.
