.garrantydecrypt Ransomware – Update January 2019

Em janeiro 2019 a new attack campaign was detected carrying a slightly different version of the ransomware note. A security analysis is not yet available for these samples and no large-scale infections are reported. This gives us reasons to believe that the changes that are made are possibly only of the note and that no other advanced components have been added.

.garrantydecrypt Ransomware – Update December 2018

.garrantydecrypt Ransomware has a new update on December 2018. It appears that there is a new GarrantyDecrypt Ransomware variant that has the following ransom note:

The ransom note indicates that the ransomware makers want 0.25 Bitcoin as a ransom sum.

.garrantydecrypt Ransomware – Distribution Tactics

The .garrantydecrypt Ransomware can be delivered using the most popular tactics just like other common viruses. One of the most effective strategies is to coordinate a mass phishing campaign using email messages. They are sent in bulk to the intended targets and are designed to look like regular notifications sent by legitimate Internet services or companies that they might use.

A similar approach is the construction of locais controlado por hackers that are designed to appear like well-known Internet portals or the official vendor sites of well-known applications. These two methods are among the main ones used to deploy portadores de carga útil infectados. There are two main types which are the most frequent ones:

  • Os documentos maliciosos — The hackers can create dangerous copies of all popular document types: apresentações, Planilhas, bancos de dados e arquivos de texto. Whenever they are opened by the victims a message box will appear asking the users to enable the built-in scripts. Whenever they are executed the .garrantydecrypt Ransomware will begin.
  • Application Bundles — The operators behind the virus can embed the dangerous code in software installers targeting the most frequently installed ones: suites criatividade, aplicações de produtividade e utilitários do sistema. Whenever they are installed on the target hosts the virus infection will also be started.

An additional method used to spread these payloads is the use of redes de compartilhamento de arquivos like BitTorrent where such contents is frequently uploaded. The hackers can distribute the virus in all of its forms and the success ratio is generally high as they are a very common platform for spreading such files.

In advanced cases the .garrantydecrypt Ransomware can also infect threats via extensões do navegador web maliciosas. They are created by the operators to support most popular browsers and are uploaded to their various repositories with elaborate descriptions promising enhancements and feature additions. When installed by the users they will run the built-in instructions which generally modify the settings in order to redirect the victims to a hacker-controlled site. After this is complete the .garrantydecrypt Ransomware will be loaded on the victim computers.

.garrantydecrypt Ransomware – In-Depth Description

The .garrantydecrypt Ransomware samples captured by the security researchers appear to be early test versions. This leads to several possible hypotheses concerning the source of the infections. The first one is that the operators behind it are developers. This means that the collective can decide for itself what features to add and implement them in the future campaigns. The other hypothesis is that the hackers that are responsible for the campaign launch have bought it from the underground hacker markets.

We presume that future versions of it will launch a series of actions against the target systems. Many of them begin infections by launching a módulo de colheita de dados. It is used to extract strings using an automated method that looks for specific information that is deemed useful to the controllers. The first group of harvested data can expose the identity of the users — the information includes strings such as their name, endereço, stored passwords and etc. The other collection is useful when constructing the unique infection ID. It is based on a generated report of the installed hardware components, operating system environment variables and etc.

When this step is complete the extracted data can be processed by another component called proteção discrição. It looks for signatures of security software such as anti-virus engines, ambientes de sandbox e hosts de máquinas virtuais. When these two modules have completed execution the virus engine will have complete control over the infected machine. This will allow it to launch multiple processes, gain administrative privileges and also hook up to system processes and third-party apps.

The next steps are to change the Valores do Registro do Windows belonging both to the operating system and the user-installed applications. Modifications to the Registry values belonging to the system itself can lead to severe performance issues, problems launching certain services and etc. When the user-installed applications are impacted this can affect their normal functionality or lead to unexpected errors.

If configured so this can also lead to a estado persistente de execução. It will set the virus engine to automatically start every time the computer is powered on. In most situations this will also disable the recovery boot menu and other services that are launched at boot time. Beware that this step also counters some manual user recovery instructions.

To further make the infections more difficult to remove the malicious engine belonging to the .garrantydecrypt Ransomware can delete System Data such as the Shadow Volume copies, backups e pontos de restauração. They can be recovered only by using a quality data recovery solution, refer to our instructions for more information on achieving this.

Another effect of the ransomare installation is its ability to install other payloads. This is done so because the ransomware has already penetrated the infected machine’s security and serves as a complex payload dropper. This allows it to manipulate the system in a way which makes it very hard to remove all infections. A very dangerous instance is the delivery of a vírus cavalo de tróia as it will establish a connection with the hacker-controlled server. It allows the operators to spy on the users in real time, take over control of their machines and hijack their information.

.garrantydecrypt Ransomware – Encryption Process

The ransomware engine will be started once all prior modules have completed. The sample files that were captured in the active campaign shows that it does not use the typical ciphers but rather a random private RSA-348 key. During the file processing several methods are used to encrypt the user data. The data itself is encrypted according to a built-in list of target file type extensions. An example one targets the following data:

  • Bases de dados
  • arquivo
  • backups
  • Música
  • vídeos
  • documentos

The affected files are renamed with the .garrantydecrypt extension. To blackmail the victim users into paying a decryption fee the virus will automatically generate a ransomware note in a file called #RECOVERY_FILES # .txt. Ele lê a seguinte:
