Two Pakistani hackers called "Kai-h4xOrR And Trojan" have managed deface some webpages of BSNL's sub-domains.
The defaced pages are:
http://learntelecom.bsnl.co.in/acp_main_module/schedule_list.asp
http://www.vas.bsnl.co.in/vas/contact_us.jsp?cir=11
They left the following message: "Team MaXiMiZerSOp# Free For Kashmir"
BSNL has very bad track record with security it has been defaced multiple times in the past few years.
