Oneeva Trojan

The Oneeva Trojan.

The Trojan horse malware category has been around for quite a lot of time and it has pretty much always been one of the most widespread forms of online threats. There are several things that make these infections so effective and popular among the hackers who use them.

For starters, viruses like Oneeva tend to be versatile in their possible uses and, unlike other common kinds of malware such as Spyware and Ransomware, Trojans can be used for the completion of a wide variety of criminal activities inside the computers of their victims.

Since Oneeva is a rather new threat and there isn’t a lot of data regarding the way it is used, we cannot tell you with a hundred percent certainty what this virus may do in your computer in case it gets there. One thing is for sure, however, and that is, if the virus is already in your system, you really shouldn’t procrastinate your attempts to remove it. There are all kinds of unpleasant and unforeseen consequences that can emerge as a result of the presence of this threat in your machine.

The Oneeva Trojan

We should mention here is that Trojans like Oneeva can also introduce other malware into the already infected systems. Ransomware is a common example of a virus class that often gets distributed via such Trojans. Therefore, if Oneeva is in your system, there’s a certain risk that there could be more malware on the computer that you don’t know about.

Even though we cannot tell you the exact end goal (or goals) of the Oneeva Trojan, we can list some of the common ways other similar viruses have been used in the past so that you know what kind of threat you have on your hands.

One common thing Trojan horse infections are capable of doing is spying on their victims’ actions and obtaining sensitive data. A lot of Trojans are used to acquire some form of personal information about their victims in order to then use it for blackmailing, harassment, banking theft, fraud, and more. What makes Trojans like Oneeva particularly good for this task is their ability to stay under the radar of even the most experienced and vigilant users.

Another thing a lot of infections similar to Oneeva are able to do is trick the user into giving Admin rights on the attacked machine, after which they start to launch different processes that usually only the user should be able to start. This basically gives the Trojan and, by extension, the hackers behind it, nearly unlimited control over the computer. Machines infected by such Trojans are commonly tasked with spreading spam to other computers, taking part in massive Denial of Service Attacks, and mining cryptocurrency for the hackers.

Removing the malware
