Groooboor Trojan – Virus Infection Methods

The Groooboor Trojan is a very dangerous Trojan which is known to the security community since 2017 when the first widespread campaign of it was detected by security researchers. It has been used by numerous hacking groups over the years in different distribution campaigns. The current campaign is focused on the use of phishing strategies and virus-infected office files in order to lead to the Trojan deployment. At this moment the identity of the hacking group is not known. We believe that they are an experienced group as they have been able to orchestrate a worldwide campaign.

The payload is based on Microsoft Word 2010 files which can be spread using common distribution methods, they are the following:

  • Email SPAM Messages — The criminals can send out email messages in a bulk-like manner that can impersonate services and companies. They can also be delivery notifications, discount offers or advertise software patches and updates. Any interaction with such emails can lead to the deployment of the relevant virus file.
  • Hacker-Controlled Sites — The criminals can create landing pages that look like landing pages, portals or other commonly accessed web pages. They can be hosted on similar sounding domain names and self-signed security certificates that will make it appear as if they are legitimate and safe to use. In many cases the creators will use similar design and may even copy down the authentic content. Through site interactions or file downloads the Trojan will be delivered to the target computers.
  • Secondary Payload Delivery — The malware can be delivered as part of the virus infection sequence of another threat.

At any time the hackers can choose to use other strateгies as well, this will vary according to the campaign, as well as the hacking approach.

Groooboor Trojan – Virus Capabilities

The detected attack campaign carries the typical malware engine, according to the available information it does not differ that much from previous versions. Its main purpose is to establish a secure connection to a hacker-controlled server which will allow the criminals to take over control of the target machines. This will allow the hackers to also steal users data and spy on the victims in real-time. Every Trojan will have a specific way of doing so — the most common one is to take screenshot between regular intervals and sending them through the instituted data stream.

The Groooboor Trojan can be programmed with additional options, some of them are the following:

  • Boot Changes — The Groooboor Trojan can install itself as a persistent threat by modifying the relevant boot configuration. As a result it will start itself automatically when the computer is launched and may even disable access to the recovery boot options. This will make it impossible to follow the directions in manual user recovery guides.
  • Data Modification — The Trojan is able to delete sensitive data, including system restore points. Alongside this some of the advanced threats of this category may also include a ransomware component which will encrypt users data and rename it with a given extension. The resulting data will be inaccessible to the users and they will be blackmailed into paying the hackers a decryption fee.
  • Windows Settings Changes — The malware can change important configuration files and the Windows Registry which can lead to serious issues. This can include performance problems to the point of rendering the computers completely unusable while the virus is active. Other consequences can be trouble with the starting of certain services and applications. Unexpected errors may also be encountered.

Identified viruses should be removed as fast as possible. In many cases Trojans like Grooobooor are programmed to deploy other malware to the systems — browser hijackers and separate file-encrypting ransomware for example. As part of this ransomware’s chain of operations a data gathering procedure can be run. It is tasked with the creation of an unique system ID which is created by a report of the installed hardware components and current software values.
