Pakistani spies used these 3 apps to hack into the laptop of Brahmos Aerospace's missile engineer Nishant Agrawal

Nishant Agrawal, former BrahMos scientist has recently been sentenced to life imprisonment by a sessions court for leaking military secrets to Pakistan. Nishant, who worked in the missile assembly unit in Nagpur, was an award-winning engineer. The sessions court has convicted him under the Section 235 of the Criminal Procedure Code. He was found guilty of offenses punishable under Section 66(f) of the Information Technology Act and various sections of the Official Secrets Act (OSA) for leaking critical information about armaments to foreign entities.
Pankaj Awasthi, UP-ATS investigation officer, said in his deposition during Nishant trial that one 'Sejal' had set up a Facebook account from Pakistan.Using this Facebook account, she chatted with Pakistani operatives and her Indian targets.

The chats showed that 'Sejal' was part of a group that shared data and tips on deceiving Indian defence staffers. Awasthi told the court that on Sejal's directions, Agrawal had clicked on links sent by her and installed three apps on his personal laptop in 2017. These apps were: Qwhisper, Chat to Hire and X-trust.
These three apps were actually malware that stole data from Nishant's laptop, which contained classified information. Investigations claim that crucial documents related to the BrahMos missile were found on his personal computers, violating BAPL’s security norms.
Nishant is said to have chatted with Sejal on LinkedIn as well, where she reportedly showed interest in hiring him, posing as a recruiter in UK's Hays Aviation.

Nishant was arrested in October 2018 through a joint operation by Military Intelligence (MI) and the Anti-Terrorism Squad (ATS) of Uttar Pradesh and Maharashtra. He was employed in the technical research section of BAPL, an Indo-Russian joint venture that manufactures BrahMos missiles.
BrahMos Aerospace is a collaborative venture between the Defence Research and Development Organisation (DRDO) and the military Industrial Consortium (NPO Mashinostroyenia) of Russia.
