Anyway, the point is that the internet isn’t secure. And actually SMS isn’t much better, which is why it shouldn’t really be used for securing anything as important as home banking. The report also described how gangs stole mobile security codes – which banks automatically send to card holders’ registered mobile phones to verify online transactions – by using either a Trojan...
