The government has taken note of news reports about alleged app 'Tek Fog' purportedly used to manipulate social media platforms, and the IT ministry has tried to locate it on prominent app stores but could not find it, Parliament was informed on Friday.

The ministry is not aware of any technical vulnerability that makes social media intermediaries susceptible to manipulation as mentioned in those news reports, Minister of State for Electronics and IT, Rajeev Chandrasekhar said in a written reply to the Rajya Sabha.
