Detailed Analysis

This worm is a variant of SymbOS/Yxes.A!worm, with which it shares most functionalities. Unlike the latter, however, the worm installation package is signed with a development certificate (instead of a Symbian certificate). Therefore, attempts to install it on factory mobile devices running S60 3rd Edition will cause a "Constrained by the certificate" error.
