Snatch Ransomware — Technical Analysis Update (Update December 2019)

Shortly after the Snatch release has been used in widespread attacks against users worldwide a detailed analysis was posted online giving further information about the virus activity. There are several distinct areas where the virus is shown to be quite different from other common threats. This is evident from the large number of malicious actions which the main engine can cause.

One of the larger outbreaks in October this year allowed security researchers to discover that after setting itself as a service (by modifying the operating system’s configuration) the virus will restart the system and enter it into Safe Mode. This is an intentional action as in this environment many anti-virus programs will be automatically disabled, alongside other services that may block the Snatch ransomware. The actual encryption will take place only when Safe Mode has been booted.

The surge of attacks indicates that the hackers aim to infect enterprise networks using automated attacks. The security researchers were able to track down several instances where computer hackers were looking for partnership with other criminals in order to deploy the Snatch ransomware. The posts gives an understanding of what the main distribution methods are — manly vulnerable remote desktop control software and services, as well as database servers.

When the hackers hijack an administrative account they will use the available assets in order to take over other hosts available on the network. This is done automatically and includes a very extensive data gathering procedure, some of the information which is hijacked will include the following:

  • WMIC System & User Data
  • Active Processes
  • Services Memory Contents
  • Computer Hardware & Operating System Values Information

All harvested data will be transmitted to a hacker-controlled server via a built-in Trojan module. The data which is to be sent will be prepared in advance and placed in a temporary location before it is sent. After the hackers have acquired the data sets the local ransomware installation will be updated with further dangerous modules. What we know from the log files is that the sequence includes a free program that is used to scan for the presence of other potential victim computers on the same network.

Apart from installing itself as a service the Snatch ransomware will institute a special protective module that will disable attempts of blocking or stopping the execution of the virus by the user. Additionally it has been observed that the main infection engine has the ability to edit out existing strings in the Windows Registry and will also create a new one for the ransomware.

To make recovery more difficult the Snatch virus will search for Shadow Volume Copies of sensitive data which will be deleted.

The ransomware engine will run just like the previous versions however instead of choosing to process all data with a given a extension based on the built-in list, some of the samples have been shown to also include a blacklist — folders which are excluded from the ransomware processing. One of the captured samples shows us which locations are protected:

C:\Program Data\start menu
C:\Program Data\microsoft
C:\Program Data\templates
C:\Program Data\favorites
C:\Program Files\windows
C:\Program Files\perflogs
C:\Program Files\$recycle.bin
C:\Program Files\system volume information
C:\Program Files\common files
C:\Program Files\dvd maker
C:\Program Files\internet explorer
C:\Program Files\reference-assemblies
C:\Program Files\tap-windows
C:\Program Files\windows defender
C:\Program Files\windows journal
C:\Program Files\windows mail
C:\Program Files\windows media player
C:\Program Files\windows nt
C:\Program Files\windows photo viewer

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.
