WikiLeaks on Thursday published a user guide describing what appears to be a tool used by the U.S. Central Intelligence Agency (CIA) to intercept SMS messages on Android mobile devices.
Named HighRise, the version of the malware described in the WikiLeaks document is disguised as an app called TideCheck, and it only works on Android versions between 4.0 and 4.3.
According to its developers, the tool must be manually downloaded, installed and activated on the targeted device – this means that the attacker needs to have physical access to the smartphone or trick victims into installing it themselves.
