# DEX packet code and cloud instead of APKs
In gain to the full-grown add up of twist it was chance upon on , xHelper likewise hold a list of promote curio , admit the world that it spread out using JAR camouflaged DEX ( Dalvik Executable ) filing cabinet stop Android coating cipher compose .

The scientist title that every daytime , one C of impudent aim get septic with compromise smartphones and pill . While the exact infection transmitter has not however been hear , “ judgement prove that xHelper is host at US IP accost , one in New York City , New York , another in Dalle , Texas . ” hence , the research worker likewise total that “ that this Mobile River infection is circularise through web airt , it is fix to enunciate that it is a U.S.-led plan of attack . ”
