Neil Daswani, who is also the CTO of security firm Dasient, says that they have studied around 10,000 Android apps and have found that 800 of them are leaking private information of the user to an unauthorized server. Neil Daswani is scheduled to present the full findings at the Black Hat Conference in Las Vegas which starts on July 30th. The Dasient researchers also found out that 11 of the apps they have examined are sending unwanted SMS messages.
