New Delhi: The world's most popular messaging app - WhatsApp, which is owned by Facebook, accepted on Tuesday that they were targeted by an “advanced cyber actor.” The security flaw gave access to the hacker to install spyware on targeted mobile phones and give access to personal details like calls, photos, location data, private messages and other information.

WhatsApp has admitted this vulnerability involved a missed call coming to the phone through the app. The hacker would then use that missed call to slide a piece of malware into the phone. The spyware can be even used to turn on the phone's microphone to capture encrypted conversations, private files and personal materials.

What is NSO Group?

It is an Israel based cybertechnologies company. NSO has developed technologies that governments and law enforcement agencies can use to track and intercept terror activity, break up organized crime operations, and even search for missing persons. NSO claims that it sells only to responsible countries after diligent vetting, and with Israeli government approval. NSO needs a Ministry of Defense licence in order to meet with potential clients who must be approved by a business ethics committee. 

Each license must receive specific government approval and every 12 months each contract is re-examined by the business ethics team before it's renewed. The company says all credible allegations of misuse of the product are investigated and in three instances, NSO has shut down its product as a result.
