.seto Virus – Update September 2019

During the first wave of the Seto virus the researchers observed several different tactics which were used more than others. A distinctive feature of the campaigns is that the hackers behind the distribution focus on creating infected payload carriers such as the following:

  • Infected Documents — The macros placed inside the documents can be placed inside different types of formats: spreadsheets, presentations, databases and text files. Whenever they are opened by the victims a prompt will be spawned asking the victims to enable them citing the reason that this is required in order to correctly view the contents.
  • Infected Software Installers — The criminals have created numerous versions of different software installers. The hackers typically will create malicious setup bundles of popular applications that are often downloaded by end users. In the case of the SETO ransomware STOP variants many of the infections are caused by downloading hacker-made IOBIT Driver Booster PRO installers.

The SETO virus can be contacted by navigating to different hacker-controlled pages, portals and scam redirects. One of the most popular outlets where such apps are found include not only web pages and phishing emails and also file-sharing networks such as BitTorrent.

.seto Virus – What Does It Do?

The .Seto virus is a crypto virus programmed to encrypt user data. As soon as all modules have finished running in their prescribed order the ransomware will prevent the users from interacting with their personal files. It will display a ransomware note to the victims.

You should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that.

If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files back to normal.

Seto (.seto) File Virus (STOP Ransomware) – Detailed Description

The Seto virus is a dangerous ransomware which is being spread by an unknown hacker or criminal group. The virus belongs to the

STOP ransomware family. Currently, we do not know if it has specific targets or the perpetrators want to execute a global infection. Similar to its predecessors, Seto virus is very possible to be spread via some of the most popular distribution tactics. Different techniques may be applied simultaneously in order that hackers can select the most appropriate one.

Frequently the hackers choose to send out email-based phishing messages to the target recipients. The emails are sent in a manner which is very similar to the way SPAM messages are sent. They will manipulate the users into thinking that they have received a legitimate message from a popular company or service. A similar technique is the creation of special-built purpose scam sites that are designed to perform the same function. Interaction with their contents will lead to the .Seto virus deployment.

In some cases the Seto virus can also be embedded in various file carriers. A popular example is the macro-infected documents: text files, presentations, databases and spreadsheets. As soon as they are opened the victims will be prompted to enable the built-in macros. If this is done the associated ransomware infection will be made. The other widely used technique is the creation of infected software installers. They are made by taking the setup packages of popular applications and modifying them with the .Seto virus code. All data can be uploaded to file-sharing networks where both legitimate and pirate data is often uploaded. To facilitate a larger distribution the hackers may also embed the necessary code into browser hijackers — dangerous web browser extensions. The hackers will impersonate both developers or users. The posted descriptions often include promises of performance optimizations or the inclusion of new features. However, as soon as they are installed the virus will be deployed automatically.

When the Seto virus has finally been placed on a given computer it will start to execute its built-in sequence. It can follow the hardcoded instructions or only run certain commands depending on the local conditions. Usually, attacks with ransomware like this virus will start with a data harvesting module. It is used to acquire information that can expose the identity of the victims (useful for other crimes) and generate a report of the installed hardware components. This data can be used to create a unique ID that is assigned to each affected device.

The collected information can then be used to scan the system for any installed applications that can block the proper .Seto virus execution. In most cases, this includes the following security engines: anti-virus programs, firewalls, virtual machine hosts, sandbox and debug environments and etc.

By default, they will be blocked or entirely removed from the system. When the threat can run freely it will proceed further to carry out other system changes:

  • Windows Registry Change — The creation or modification of existing values found within the Windows Registry. This will lead to serious performance issues, problems when running certain functions or operating system features. The users may also find it very difficult to use their computers normally as they can face sudden errors.
  • Additional Malware Delivery — The .Seto virus can be used to deploy other threats to the infected hosts. This includes Trojan horses which can take over control of the computers and allow the hackers to spy on the victims in real-time. The other popular threat which can be attributed to this virus’s installation is the cryptocurrency miner. It is mostly found with the browser redirect infections where the malicious code is delivered through a rogue extension. When the miner is activated it will download a sequence of small resource-intensive jobs. They are complex mathematical calculations that will place a heavy load on the computer’s resources. For every reported successful task the hackers will receive cryptocurrency directly into their digital wallets.

In addition, the .Seto virus cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

When applied this command minimizes the chances of recovering .seto files by one.

When all dangerous Seto virus modules have finished running the actual file encryption will begin. Like other similar threats, the actual file processing will be modeled on the typical ransomware virus action — a strong cipher will encrypt target user data according to a list of defined file types. Examples are the following: multimedia files, archives, backups, databases, archives and etc.

In the end the Seto virus will assign the custom extension .seto to the processed files showing that the users cannot access them. A ransomware note will be then activated in order to blackmail the users into paying the hackers a decryption fee.

Here is a copy of Seto virus’ ransom message which is named _readme.txt:
