Snatch Ransomware – How Did I Get It and What Does It Do?

The .wvtr0 virus is a new release that is descendant from the Snitch ransomware family which was detected in a recent attack campaign. At the moment there is no information available about the hacking group behind the campaigns. Given the fact that this is a modified version of te former threat it is very possible that the criminals have taken the original source code and modified its configuration options. It is very possible that the most common distribution methods will be used. This includes the setting up of malware file carriers — they are usually dangerous documents (containing virus-infected macros) of all popular formats. The other type is the creation of virus-infected app setup bundles of popular software that is often downloaded by end users.

All of these files can be easily delivered to the intended victims by uploading them to file-sharing networks and also fake download portals. Bear in mind that phishing strategies can also be used to coerce the victims into interacting with them. This can be done either by sending of email messages or even using fake or hacked accounts and posting contents on social networks. Advanced versions of it can infect the target users by carrying the virus code in malware browser plugins.

As soon as the .wvtr0 virus is started on a given machine it will immediately run the built-in modules depending on the local conditions or specific hacker instructions.

The made security analysis of one of the samples shows that the virus is capable of launching a very complex sequence of modules. At the onset of infection one of the first actions which are started are related to initial security bypass. This is a mechanism which will search for any installed security services that can block the ransomware: anti-virus products, firewalls, intrusion detection systems and etc. This will allow the main engine to continue running with the other modules. A common module which will be run is the information gathering one. It will harvest data that can be categorized as either belonging to the machines or personal information about the victims.

What’s more dangerous about the .wvtr0 virus is that it can be used to detect and delete sensitive data — the analyzed samples shows that this is the case with the Shadow Volume Copies. What’s more dangerous is that this ransomware can also access and modify the Windows Registry leading to performance issues and problems with running certain functionality. This can also be connected to the persistent installation — the .wvtr0 virus will be started every time the computer is started and may also block access to the recovery boot options.

Apart from the typical ransomware components the analysis also shows that the main engine will enable a Trojan component which will establish a secure connection to a hacker-controlled server. This allows the criminal group to take over control of the machines. Other actions include the spying of the users and data theft.

When all contained within components have finished running the encryption phase will start. Using a strong cipher target user data will be encrypted by a strong cipher resulting in the renaming of the files with the .wvtr0 extension. The associated ransom note is created in a file called RESTORE_WVTR0_FILES which contains instructions that will blackmail the victims into paying the hackers a decryption fee.
