Troj/Pdfex-HM is a Trojan that is spread by attackers via a spam Apple email incorporating a falsified invoice for a $699.99 postcard. The malicious Apple invoice email encompasses a link 'View/Download' which, if clicked by an affected computer user, downloads the file called 'download.jpg.exe', while the 'Cancel' and 'Not your order' links download the file called 'check.php'. If recipient clicks on any of the web-links, he/she is redirected to an unrelated website claiming to be the IRS and saying the computer user is using an unsupported web browser. Once this website is displayed, in the common way of the Blackhole exploit kit, it aims at distributing exploits against Adobe Flash Player, Adobe Reader and Oracle Java. If any of these are successful, it takes over the infected machine with Troj/Pdfex-HM. If any of these do not work, the image has links to download an 'up-to-date' version of these web browsers that simply downloads a file called 'update.exe'. If the computer is is exploited or downloads and runs the file his/her PC is contaminated with Troj/Pdfex-HM, which is created to log keystrokes and hack bank accounts of the victim.
