How DNSChanger Malware Works.

DNSChanger is malicious software (malware) that changes a user’s Domain Name System (DNS) settings, in order to divert traffic to unsolicited and potentially illegal sites.

Beginning in 2007, the cyber ring responsible for DNSChanger operated under the company name “Rove Digital” and used the malware to manipulate users’ Web activity by redirecting unsuspecting users to rogue DNS servers hosted in Estonia, New York, and Chicago. In some cases, the malware had the additional effect of preventing users’ anti-virus software and operating systems from updating, thereby exposing infected machines to even more malicious software.


FBI has since seized the rogue DNS servers and the botnet’s command-and-control (C&C) servers as part of “Operation Ghost Click” and the servers are now under their control. To assist victims affected by the DNSChanger, the FBI obtained a court order authorising the Internet Systems Consortium (ISC) to deploy and maintain temporary legitimate DNS servers,

Tech Giants to use NAC-Tech test for hiring.


In a move to filter the 'quality' of engineering graduates hired,  software majors TCS , Infosys, Wipro, Accenture, Cognizant and HCL have agreed to use the NAC-Tech test or the Nasscom assessment for competence in technology test

According to ET Now, this test will serve as a pre-requisite for entry level hiring in the technology sector. Industry body Nasscom has been pushing for the adoption of this initiative. This has been done in light of the fact that huge retraining costs are incurred by the IT companies. 

Mobile radiation lowered September 1, 2012.


If you are worried by the radiation emitted by cellphone towers around you, there is some good news. From September 1 this year, India will lower the level to one-tenth of the prevailing standard - from 9.2 w/m2 (watt per square metre) to 0.92 w/m2. The decision follows a report of the inter-ministerial committee formed by the ministry of communications and information technology to study the hazards posed by EMF (electromagnetic field) radiation from base stations and mobile phones.

Dr R S Sharma, deputy director general of Indian Council of Medical Research (ICMR), who represented the health ministry on the committee, said the new norms will place India among the more radiation conscious countries. "India's current radiation exposure limit (9.2 watt/m2) for mobile towers is higher than countries like Russia (0.2 w/m2) and China (0.4 w/m2). In USA, Canada and Japan, however, the radiation exposure limit is much higher (12 w/m2)," he said.

Users can send Email via sms : Google


Gmail users can now send and receive their emails via their feature phones, thus doing away with the need of a smartphone or constant internet connectivity. However, this service will currently be available in Ghana, Nigeria and Kenya only but is likely to be launched in other regions later. It will help the search giant reach out to a larger audience in countries which do not have much mobile internet penetration.
