Kaspersky Lab: In the first quarter of 2014, spammers began to mimic messages from mobile apps. They showed a particular preference for popular mobile messengers such as WhatsApp, Viber and Google Hangouts. Specifically, notifications that were supposed to come from applications αυτές χρησιμοποιήθηκαν για την εξάπλωση κακόβουλων προγραμμάτων, αλλά και αβλαβών διαφημίσεων. Η αυξανόμενη δημοφιλία των φορητών συσκευών σημαίνει ότι οι επιθέσεις Phishing aimed at users' Apple IDs are becoming more and more common.
Many mobile device owners are familiar with synchronizing their contacts and receiving messages from mobile applications via email. Therefore, few would suspect the fact that WhatsApp is not directly connected to any service e-mail. However, this omission could prove costly, since the attached file of an email contained the infamous Backdoor.Win32.Androm.bjkd. The main function of this malicious program is to steal personal data from users.
"Recently we have noticed an increase in the number of attacks that target mobile device users. Gadgets have become popular even among those who have not had much contact with computers and are less familiar with their security. This creates new attack vectors for spammers and phishers. For their protection, users should remember not to open emails from unknown senders and especially not to click on any link contained in these emails, as they inevitably compromise their security. By 'clicking' on an insecure link, users are putting their security at risk, no matter what device they're using - whether it's desktop or mobile," noted Darya Gudkova, Head of Department Content Analysis & Research by Kaspersky Lab.

Most of the popular malware programs are now multifunctional: they can steal data from the victim's computer, make a computer part of a botnet, or download and install other malware without the user knowing it.
