The OLX advertising portal warns against false announcements. According to the portal some of the recently added messages contain a link with infected application.

Fake messages usually refer to job offers and in some cases also to free toy giveaways. Any person who, in response to an advertisement, has sensed his or her CV receives a link allegedly leading to a new application, which the victim is asked to test.

However, in reality the application infects the victim's device with a vicious malware, capable for example of intercepting the victim's bank logging data.

The security experts from Next portal have denoted the malwares as Spy.Banker.RW and Marcher/Exoboto. The viruses are able to send and read SMS messages, take control over network communication and turn off sound and vibrations in the phone. The victim will not even notice that his or her phone has received a text message authorizing banking operation.
