Security Vendors Alerted for an Increase in W32/VBNA-X Worm

According to a report by the security industry biggies including Symantec, MacAfee, Kaspersky, and Sophos a rise in the number of computer worm by usually called as W32/VBNA-X seems to be dispersed and has been noticed over a period of time from now.

Although the worm is officially a bug, it performs Trojan in few respects, given that it seems to spread through Autorun.inf files on thumb drives and removable media while opening the door to the other malwares at the same time.

Security experts while commenting on the same claimed that when the AutoRun problem is confronted by netizens, they can very easily think that the issue must have been solved by Microsoft. Actually, the crooks have shut it down once there motive of dispersing the earlier variants of the Stuxnet worm targeted to the control systems that managed centrifuges at Iran's Natanz nuclear enrichment facility were accomplished. Nevertheless, after this event, whenever people come across the word AutoRun popping up in headlines, they think it to be a security nuisance and take it in a latent manner, as reported by threatpost.com on November 30, 2012.

However, as per Sophos, users are not that well acquainted towards patching up their machines. The problem seems to be a very old and stubborn trouble that seems to remain unchanged. Although Microsoft shipped a patch to disable Autorun almost two days ago, some users still haven't come around towards executing it resulting in its spreading.

According to Trend Micro, types of WORM_VOBFUS (or W32/VBNA-X) were masquerading on Facebook and sexually-suggestive file names, such as Sexy.exe, Porn.exe. Using sex and provocative subjects to attract users into running a malicious file was the protagonist's mission while committing the cyber threat. What does these shows? Users continue to react to such social engineering ploy.

The recent outbreak reaches about a year and a half after Microsoft declares the major decrease in the infection rate of AutoRun. During the first five months of 2011, the number AutoRun-related malware found by Microsoft declined to 59% on XP computers and 74% on vista PS's in contrast to 2010.
