.garrantydecrypt Files Virus is one that encrypts your data and demands money as a ransom to get it restored. Files will receive the .qweuirtksd extension as a secondary one, without any changes made to the original name of an encrypted file. The .garrantydecrypt Files Virus will leave ransomware instructions inside a text file. Keep on reading the article and see how you could try to potentially recover some of your locked files and data.

.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 hacker-controlled sites 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 infected payload carriers. There are two main types which are the most frequent ones:
- Malicious Documents — The hackers can create dangerous copies of all popular document types: presentations, spreadsheets, databases and text files. 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: creativity suites, productivity apps and system utilities. 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 file-sharing networks 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 malicious web browser extensions. 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 data harvesting module. 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, address, 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 stealth protection. It looks for signatures of security software such as anti-virus engines, sandbox environments and virtual machine hosts. 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 Windows Registry Values 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 persistent state of execution. 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 and system restore points. 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 Trojan horse virus 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:
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. It reads the following:
All your files have been ENCRYPTED
Do you really want to restore your files?
Write to our email – [email protected]
and tell us your unique ID
[redacted 0x200 bytes in base64]
