The website http://www.tcs.com which belongs to India’s IT giant Tata Consultancy Services gets hacked by a French hacker. When I write this post, the TCS group have not still resolved the problem. Itx more likely that it is not a web software hack,but an attack through DNS loophole.
If you visit TCS.com you will get a screenshot as shown below, telling that they have put up the domain name for sale.
