Over 1.75 billion mobile phone users will have used their devices for banking purposes by the end of 2019, compared to 800 million this year, according to Juniper Research.
An estimated $3.75 billion have been netted by a single fraud ring that took advantage of a popular Brazilian payment method - the Boleto - by wielding a frequently upgraded piece of malware that silently intercepted and rerouted payments to the crooks' bank accounts.
A highly versatile piece of Android malware has been unearthed by FireEye researchers.
The distribution potential of the infamous Cridex infostealer (also known as Feodo or Bugat) just went up a notch, as a new version of the malware works in conjunction with a worm that sends out emails with a link to download a zip file containing the trojan.
Careful online banking users can sometimes spot that something is amiss when malware installed on their computer pops up phishing pages or adds fields to legitimate banking forms.
