If you are a WhatsApp user who has a habit of innocently accessing every file that is sent to you – beware!

A hacker, sitting thousands of miles away in the comfort of his home, may be trying to steal your bank details or other precious private information of use.

A virus disguised as a Microsoft Excel file after being accessed can gather sensitive information from the user’s device.

So far, hackers have only targeted WhatsApp users in India, especially defence personnel.

However, many believe that this can be imitated by hackers in other countries across the globe.

In India, central security agencies have alerted defence and security personnel against the malicious activity of the virus, falsely bearing the name of Organisations like NDA and NIA, that may breach and hack into their personal information and banking data.

The two files, as per the advisory accessed by PTI, are–“NDA-ranked-8th-toughest-College-in-the-world-to-get-into.xls” and “NIA-selection-order-.xls”.

Officials privy to the contents of the advisory said the NDA here is understood to be indicating to army’s National Defence Academy in Khadakwasla in Pune while NIA to the premier terrorist incidents’ probe organisation– the National Investigation Agency.

It is understood that the malicious virus-laden file is formatted in the form of ‘MS Excel’ file majorly, but officials did not rule out it’s aliases in the ‘MS Word’ or ‘.PDF’ formats to attack a user’s phone and data.

“As these two organisations are very popular and known within the country and abroad and there is a curiosity to know more about them, it is possible that it may affect the mobile phones of people interested in these subjects. However, it has been analysed that the men and women in defence, paramilitary and police forces could be the target groups,” they said.
