July is traditionally considered a quiet month in terms of information security. Thus, in most cases, our specialists detected modifications of already-known threats. For example, at the beginning of July, we added to our virus database yet another signature for Linux.Encoder.4, which works in Linux operating systems. Judging by information posted on one foreign blog, this Trojan was the result of a student research project, and it was not being spread in the wild.
In the end of July, our security researchers registered the emergence of Trojan.MulDrop6.48664—a dropper Trojan that installs the infamous BackDoor.TeamViewer.49 on computers. (For more details about BackDoor.TeamViewer.49, refer to this news article.) However, this time, hackers disguised the dropper as a questionnaire application that was allegedly being distributed by a popular Russian airline.

In addition, the past month was marked by the emergence of Android.Spy.178.origin, the Trojan incorporated into a modification of the popular game—Pokémon Go. Criminals used this Trojan to gain access to confidential user data.
