What happened during the destructive malware attacks targeting Ukrainian organizations in January 2022?

In January 2022, Microsoft identified intrusion activity in Ukraine involving a two-stage malware attack. Stage 1 overwrote the Master Boot Record (MBR) on victim systems with a fake ransom note, rendering systems inoperable. Stage 2 involved a downloader that fetched a file corrupter malware from a Discord channel, which then overwrote the contents of files with specific extensions, making data unrecoverable. The ransom note included a Bitcoin wallet and Tox ID, but lacked typical features of criminal ransomware, such as victim-specific IDs or recovery mechanisms. Note: This attack was atypical for ransomware and focused on destruction rather than financial gain.

Destructive malware targeting Ukrainian organizations

January 18, 2022

Microsoft identified intrusion activity originating from Ukraine that appeared to be possible Master Boot Records (MBR) Wiper activity. During investigation, analysts found a unique malware capability being used in intrusion attacks against multiple victim organizations in Ukraine. Stage 1: Overwrite Master Boot Record to display a faked ransom note The malware resides in various working directories, including C:PerfLogs, C:ProgramData, C:, and C:temp, and is often named stage1.exe. In the observed intrusions, the malware executes via Impacket, a publicly available capability often used by threat actors for lateral movement and execution. The two-stage malware overwrites the Master Boot Record (MBR) on victim systems with a ransom note (Stage 1). The MBR is the part of a hard drive that tells the computer how to load its operating system. The ransom note contains a Bitcoin wallet and Tox ID (a unique account identifier used in the Tox encrypted messaging protocol) that have not been previously observed by MSTIC: Your hard drive has been corrupted. In case you want to recover all hard drives of your organization, You should pay us $10k via bitcoin wallet 1AVNM68gj6PGPFcJuftKATa4WLnzg8fpfv and send message via tox ID 8BEDC411012A33BA34F49130D0F186993C6A32DAD8976F6A5D82C1ED23054C057ECED5496F65 with your organization name. We will contact you to give further instructions. The malware executes when the associated device is powered down. Overwriting the MBR is atypical for cybercriminal ransomware. In reality, the ransomware note is a ruse and that the malware destructs MBR and the contents of the files it targets. There are several reasons why this activity is inconsistent with cybercriminal ransomware activity observed by MSTIC, including: Ransomware payloads are typically customized per victim. In this case, the same ransom payload was observed at multiple victims. Virtually all ransomware encrypts the contents of files on the filesystem. The malware in this case overwrites the MBR with no mechanism for recovery. Explicit payment amounts and cryptocurrency wallet addresses are rarely specified in modern criminal ransom notes, but were specified by DEV-0586. The same Bitcoin wallet address has been observed across all DEV-0586 intrusions. It is rare for the communication method to be only a Tox ID, an identifier for use with the Tox encrypted messaging protocol. Typically, there are websites with support forums or multiple methods of contact (including email) to make it easy for the victim to successfully make contact. Most criminal ransom notes include a custom ID that a victim is instructed to send in their communications to the attackers. This is an important part of the process where the custom ID maps on the backend of the ransomware operation to a victim-specific decryption key. The ransom note in this case does not include a custom ID. Microsoft will continue to monitor DEV-0586 activity and implement protections for customers. The current detections, advanced detections, and IOCs in place across security products are detailed below. Stage 2: File corrupter malware Stage2.exe is a downloader for a malicious file corrupter malware. Upon execution, stage2.exe downloads the next-stage malware hosted on a Discord channel, with the download link hardcoded in the downloader. The next-stage malware can best be described as a malicious file corrupter. Once executed in memory, the corrupter locates files in certain directories on the system with one of the following hardcoded file extensions: .3DM .3DS .7Z .ACCDB .AI .ARC .ASC .ASM .ASP .ASPX .BACKUP .BAK .BAT .BMP .BRD .BZ .BZ2 .CGM .CLASS .CMD .CONFIG .CPP .CRT .CS .CSR .CSV .DB .DBF .DCH .DER .DIF .DIP .DJVU.SH .DOC .DOCB .DOCM .DOCX .DOT .DOTM .DOTX .DWG .EDB .EML .FRM .GIF .GO .GZ .HDD .HTM .HTML .HWP .IBD .INC .INI .ISO .JAR .JAVA .JPEG .JPG .JS .JSP .KDBX .KEY .LAY .LAY6 .LDF .LOG .MAX .MDB .MDF .MML .MSG .MYD .MYI .NEF .NVRAM .ODB .ODG .ODP .ODS .ODT .OGG .ONETOC2 .OST .OTG .OTP .OTS .OTT .P12 .PAQ .PAS .PDF .PEM .PFX .PHP .PHP3 .PHP4 .PHP5 .PHP6 .PHP7 .PHPS .PHTML .PL .PNG .POT .POTM .POTX .PPAM .PPK .PPS .PPSM .PPSX .PPT .PPTM .PPTX .PS1 .PSD .PST .PY .RAR .RAW .RB .RTF .SAV .SCH .SHTML .SLDM .SLDX .SLK .SLN .SNT .SQ3 .SQL .SQLITE3 .SQLITEDB .STC .STD .STI .STW .SUO .SVG .SXC .SXD .SXI .SXM .SXW .TAR .TBK .TGZ .TIF .TIFF .TXT .UOP .UOT .VB .VBS .VCD .VDI .VHD .VMDK .VMEM .VMSD .VMSN .VMSS .VMTM .VMTX .VMX .VMXF .VSD .VSDX .VSWP .WAR .WB2 .WK1 .WKS .XHTML .XLC .XLM .XLS .XLSB .XLSM .XLSX .XLT .XLTM .XLTX .XLW .YML .ZIP If a file carries one of the extensions above, the corrupter overwrites the contents of the file with a fixed number of 0xCC bytes (total file size of 1MB). After overwriting the contents, the destructor renames each file with a seemingly random four-byte extension.
