EDGE 2020 Goes Virtual
Fortinet® (NASDAQ: FTNT) - a leading network security provider and worldwide leader of unified threat management (UTM) solutions – today announced its May 2010 threat report showed a new PDF exploit being circulated in high volume through an ongoing spam campaign.
The vulnerability, first blogged about by Didier Stevens on March 29, 2010, is CVE-2010-1240, and the malicious documents now exploiting this are detected by Fortinet as PDF/Pidief.BV!exploit. Though no patch exists, Adobe has recommended mitigation strategies on its blog. To further combat the threat, Fortinet recommends implementing an intrusion prevention and antivirus solution. This vulnerability was ranked second for overall malware activity this month, behind only the nefarious Pushdo botnet.
“What sets PDF/Pidief.BV apart from other PDF threats we are seeing, is that it requires user interaction,” said Derek Manky, project manager, cyber security and threat research, Fortinet. “More specifically, a user needs to click on the ‘open’ button when prompted by a dialog box to initiate the infection. This threat is another reason why it’s imperative for users to carefully read messages when they appear.”
In the case of PDF/Pidief.BV, clicking “open” will first execute VBScript and then add a malicious botnet loader binary, which compromises the system. For detailed information on this specific PDF attack, please view our FortiGuard virus encyclopedia entry here.
Botnet Activity on the Rise Botnet activity remained strong in this report, with Gumblar and Sasfis present in both the Top 10 Attack and Top 10 Malware lists. Though the main botnets−such as Pushdo, Cutwail and Sasfis− continue to pose significant threats, newer botnets are emerging.
Fortinet first detected the CMultiLoader botnet in the wild on April 8, 2010. A variant of this botnet, W32/CMultiLoader.A, has landed in the sixth spot in our Top 10 Malware list this report. The Katusha botnet (W32/Katusha.1824!tr ) just missed the Top 10 list this report, ranking #11. These are two examples of up and coming botnets that are making waves. Total detected malware volume has remained fairly consistent since the beginning of the year, though distinct detection continues to rise. This indicates more variations of malware are circulating in cyberspace as malware creators continue to pack, encrypt and morph their malicious binaries.
