In May, WhatsApp has said it became aware of NSO
Group having used a coding glitch in the messaging app that let its customers spy on some people. WhatsApp fixed the issue, and worked with Citizen Lab, a digital and human rights research group, to contact all those affected, telling them what they could do to keep their communications safe. On October 29, WhatsApp decided to sue NSO Group for misusing the messaging platform’s code to compromise user privacy.
NSO Group has maintained that it sells Pegasus only to governments. The Indian government has already asked WhatsApp to explain the breach of Indians' privacy but has also come under some heat for not answering whether any of its agencies bought Pegasus software.
On Friday, 19 Indians whose devices were targeted by Pegasus through WhatsApp wrote an open letter, asking the government to reveal information in this regard.
“As affected persons and concerned citizens, we appeal to the Government of India to reveal whatever information it has about this cyber attack, other similar methods of mass surveillance and the identity of the concerned players," went the letter.
One outcome is that a number of people, including bureaucrats and journalists, have moved to alternative messaging platforms such as Signal or Telegram.
