WhatsApp, the maker of a popular cross-platform mobile chat program, has been in talks to be acquired by Facebook, sources tell TechCrunch.
TechCrunch had no information about a possible price range or how advanced the talks might be.
WhatsApp said: "The reported story is a rumor and not factually accurate. We have no further information to share at the moment."
Founded in 2009, the Santa Clara, Calif.-based company provides a smartphone app for Android, BlackBerry, iOS, Symbian, and Windows Phone that delivers text messages, as well as images and audio and video messages. The ad-free app reportedly has about 100 million daily users, with a presence in 250 countries on a variety of platforms.
The startup noted all the way back in October 2011 that it was serving up 1 billion messages per day: "Just how much is 1 billion messages? That is 41,666,667 messages an hour, 694,444 messages a minute, and 11,574 messages a second," the company wrote in a blog post at the time. The company added that it was a "small step closer towards our goal: providing a great mobile messaging system for a global market, regardless of your handset."
The WhatsApp Messenger app came under criticism recently from security and mobile researchers whobased on its authentication process. Several anonymous bloggers called the process a "security nightmare," saying the app leaked data collected off the device when it's being sent to servers. A research paper also concluded that the local database storage encryption could be decrypted.
