Fake virustotal website propagated java worm
The infection strategies using java script technology are on the agenda and that because of his status as a "hybrid", criminals looking to expand its coverage of attack recruiting infected computers regardless of the browser or operating system you use.
In terms of criminal activities, the techniques of Drive-by-Download by injecting malicious java script in different websites, are a combo of social engineering that requires users to increasingly sharpen the senses of "detection".
During this weekend, we encountered a fake website of the popular system analyzes suspicious files Virustotal, by Hispasec company, touted to infect users through the methods mentioned above.
A view of users, the website looks the same way as the original. However, hidden in the source the parameters needed to infect the system through a java applet through which discharge completely silent malware detected by Kaspersky Lab as Worm.MSIL.Arcdoor.ov.
The worm is developed to recruit zombies that will be part of a botnet designed primarily to perform DDoS attacks synflood, httpflood, udpflood and icmpflood. The communication focuses on a C&C that stores information obtained from the victim machine. Some of the parameters involved in the communication are:
& mode: type of DDoS attack
&botver: malware version
&pcname: name victim machine (hostname)
&winver: type and versión of operating system
Usually these attacks through a centralized hub from which the attacker manages malicious maneuvers using web applications DDoS Framework such as N0ise (used in this case), Cythosia, or NOPE. Such applications have a high impact and demand in terms of development, especially since the European zone of Germany.
Kaspersky Lab detects this threat proactive and continues the investigations into these criminal activities.

Why censor these? Why do people censor screenshots of malicious sites? |

Re: Why censor these?
Hi Rod-
Simple answer - we are in the business of protecting customers and preventing infections, not spreading malicious links. Yes, sometimes we may post a link, but I believe that Jorge darkened the link here so that kids and individuals would not mistakenly visit the site and infect their own system.
Yes, that sort of thing happens. Some of us have learned the hard way, but unfortunately it does happen.
Kaspersky Lab has been a vendor in this business for a long time. Frequently, our researchers share and receive information with other vendors and organizations about malware, including the one in this fine post. You can dismiss your concern that we don't share information with other vendors and sec pros, because we do just that within infosec communities. The industry is highly competitive, but the knowledge share occurs.
Jorge found it interesting and blogged about it. I learned something and I am hoping that you did too. Thanks for the questions and please enjoy the posts.

Re: Useless report/alert
Hi Smokey- thanks for the questions. It's great that you understand the security problems that were are dealing with here. Surely, the DDoS framework described and the social engineering piece are interesting. Do you know of another phony Vtotal site used right now for malware delivery?
Please see my response to Rod's comment above.

I found a site selling a fake VirusTotal uploader... it was advertised at hxxp://www.wardom.com.tr/ on the front page for some time... and there were several boasts on the site giving screenshots of exactly one of the pieces of malware that has been used against me to try to discredit my very small beginning efforts on VirusTotal... and to prevent my being able to successfully upload the large amount of malware of all kinds on my system... |

Kaspersky - You need help! You don't know how funny I find this. You're representing Kaspersky and you don't even know what a Java Drive-By is? Okay, let me explain to you what a Java Drive-By is so you can re-write this article correctly. A Java Drive-By is a web application that can be used to download an executable file pretty much anywhere on the user's computer and executed once downloaded when they press "Run". |
