A zero-day vulnerability can be exploited on the same day a weakness is discovered in software before a fix becomes available from its creator.
The spyware was developed by an Israeli cyber intelligence company, the NSO Group, according to the report. WhatsApp found out in early May this year that attackers were able to install surveillance software on both iPhones and Android phones by making calls to targets on the app.
Merely making calls was enough to compromise the end-to-end encryption on WhatsApp, allowing others to eavesdrop on messages and calls, the report stated. WhatsApp is owned by Facebook after a multi-billion dollar acquisition.
An update to the app was published May 13 urging users to upgrade to it to get the patch for the vulnerability.
