A Pakistani spy who went by the Facebook nickname 'Sejal Kapoor' managed to hack into the computer systems of more than 98 officials from various defense forces and organizations, including the Indian Army, Air Force, Navy, paramilitary forces and state police personnel in Rajasthan, Madhya Pradesh (MP), Punjab and UP between 2015 and 2018, reports Times of India on June 20. She "trapped" her targets by showing her videos and pictures with the help of a software malware released from a third-party server hosted in a West Asian country. She was involved in the case related to the leak of classified data on BrahMos missile in 2018. Accessed chats show the details of the malware called 'Whisper' used by her. Malware is an abbreviated form of 'malicious software' that is specifically designed to gain access to or damage a computer, usually without the knowledge of the owner. Sejal's Facebook account had cropped up following the arrest of BrahMos senior systems missile projects engineer Nishant Agarwal by the Uttar Pradesh (UP) anti-terrorism squad (ATS) and military intelligence (MI) for passing on classified information about the project to Pakistan spy agency Inter Services Intelligence (ISI). "Instantly, after getting downloaded, the malware first prompts the user to key in a code. It's to ensure that the app is not a virus or malware. Immediately after that, it scans all latest attachments sent from the computer in emails or downloads. It then scans all files with photographs, databases of MS Word and MS Excel, by first verifying their encryption keys and then opening their passwords," said a senior intelligence official.
