Massive campaign to spread/infection Waledac launched by using as excuse the Independence Day of USA

After a long period of inactivity, the creator (or creators) of the trojan Waledac, executed yesterday July 4 (U.S. Independence Day), a new campaign to spread using the same mechanism that characterizes Waledac and characterized Nuwar in time; Social Engineering.

This time the excuse is Independence Day which is celebrated in the U.S. and the mechanism of propagation is the simulation of a video showing the alleged fireworks for the celebration of the special day.

It's likely that this massive campaign to spread/infection ends with a fairly high rate of infection because the vector by which the threat is spreading is the email that respecting a characteristic of spam, massive, reaching millions users utilizing the computational power of the botnet comprising Waledac.

We don't currently have any relevant characteristic that differentiates the mechanism of spread used on this occasion in relation to the above, perhaps the activity period is extended for a good while.

Still, there are obvious analogies. For example, continues to make use of BlackHat SEO techniques in the composition of domain names alluding to the excuse used by (firework, 4th, independence, happy, july, movies, video).

Among the domain names created from these words are (an active spreading waledac):

Through the monitoring carried out this threat since he was born under the name Nuwar can see this information graphically.

Similarly, we can visualize a lot of graphic information such as IP addresses involved in the dissemination of Waledac. In this case, the Top 10 and, considering that the campaign is focused in the U.S. (although this does not mean that the number of people infected is limited to the U.S.), it's logical to believe that the majority of infections are given in first instance in this country.

On the other hand, continues to implement Waledac masking technique as Fast-flux techniques, using different IP addresses for the same domain.

video4thjuly .com > United States > United States > Israel > Uruguay > Chile > Paraguay > Argentina > United Kingdom > United States > Brazil > United States > Argentina > United States > Russian Federation > Russian Federation

Waledac has emerged from the shadows once again turning its classic strategy that will continue to spread its campaign to spread/expand their botnet infection with the recruitment of more zombies.
