Two students of a Punjab-based private university claimed to have worked out a solution to ransomware. BhavKaran Singh and Dev Aggarwal, fourth semester students of Chandigarh University and pursuing computer science engineering, said an affected device could easily be restored by following simple steps.
Ransomware attack locks a device, such as a computer, tablet or smartphone and then demands a ransom to unlock it.The software is normally contained within an attachment to an email that masquerades as something innocent. Once opened, it encrypts the hard drive, making it impossible to access or retrieve photographs, documents or music. The attack has so far been reported from Gujarat, Odisha, West Bengal, Andhra Pradesh and Maharashtra. “We have been closely following reports pertaining to the ransomware attack and decided to work on it. On an average, we used to work for eight-10 hours daily, especially at night. An affected laptop can be easily be restored now,” said Bhav Karan
BhavKaran Singh is also a certified ethical hacker, certified cyber security analyst, part-time freelancer and developer.
