In the language of the lightning network, neutrino combines the speed of the lightning network with all the energy and security of the entire blockchain, so that users do not have to run full nodes or trust the Electrum server. Best of all: It's "light enough" to allow users to operate on mobile devices and use Bitcoin anytime, anywhere.
In response to the attack, Beosin Chengdu Chain Security analyzed: This wallet Electrum was attacked, mainly because the kivy framework used was using a standard py compiler and the wallet was not protected against secondary packaging, and the core files could be recompiled directly back into the py file.
