Mal/Zbot-JG is a Zbot Trojan that circulates via a spam email pretending to be an invoice from Apple for a $699.99 postcard. The deceptive Apple invoice email includes a link 'View/Download' which, if clicked by a PC user, downloads the file called 'download.jpg.exe', while the 'Cancel' and 'Not your order' links download the file called 'check.php'. If a recipientclicks on any of the web-links, he/she is redirected to an unrelated website claiming to be the IRS and saying the Pcomputer user is using an unsupported web browser. Once this web page is displayed, in the common way of the Blackhole exploit kit, it strives to distribute exploits, against Adobe Flash Player, Adobe Reader and Oracle Java. If any of these are successful, it takes over the affected computer with Mal/Zbot-JG. If any of these do not work, the image has links to download an 'up-to-date' version of these Internet browsers that simply downloads a file called 'update.exe'. If the PC user is exploited or downloads and runs the file, his/her machine is corrupted by Mal/Zbot-JG, which is made to record keystrokes and hack bank accounts.
