.arrow Files Virus – How Does It Infect PC

The infection process of this ransom virus is done via a very often used method of infection – via spammed e-mails. Such messages have the goal to deceive victims into opening a malicious e-mail attachment by believing it is an actual legitimate file. The attachments sent, carrying the infection file of Dharma .arrow ransomware are very well designed and may appear as if they are asking you to download important documents from the likes of:

  • Invoices.
  • Banking statement documents.
  • Receipts of orders you may or may not have made.
  • Other suspiciously important files.

In addition to this, the e-mails that carry the infection files of this variant of Dharma ransomware, using the .arrow file extension are created as if they come from actual employees from big companies in order to increase trust, for example:

Besides via spammed e-mail messages, the latest variant of Dharma ransomware may also be spread via other methods as well, such as pretending to be legitimate setups of software, key generators, fixes or patches for games and other software license activation executables. If you look for software downloads online that are free, it is always a good idea to check the files beforehand by using online services like VirusTotal. If you download e-mails that are suspicious and are in .rar or .zip archives, we advise to check if the archives are malicious via free online archive scanners, like ZipeZip.

Dharma .arrow Files Virus – Malicious Activity

When the infection with the .arrow Dharma ransomware has already taken place on victims’ computers, the first activities the virus does are preoperational, like:

  • It will touch some of the Windows system files to obtain administrative privileges.
  • It will create mutexes.
  • Interacts with the Windows Registry Editor.
  • Deletes system backups as well as shadow volume copies.
  • Changes the wallpaper or automatically schedules the ransom note file to open on the victim’s desktop.

This only happens after Dharma .arrow ransomware has dropped it’s malicious files. They may reside in the following Windows folders:

  • %AppData%
  • %Temp%
  • %Windows%
  • %Local%
  • %LocalLow%
  • %Roaming%

In addition to dropping it’s malicious files, the .arrow variant of Dharma ransomware may also modify the Run and RunOnce Windows registry sub-keys in order to add entries in them that make it to automatically run each time you login. They have the following locations:

→ HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\

Those sub-keys are responsible to run programs on Windows Boot, so Dharma may also run programs that delete the shadow volume copies on system boot. The shadow volume copies are the only way to recover files via the Windows Recovery method, so the malware makes sure to run the following commands as an administrator to destroy any chances of you recovering your files this way:

→ bcdedit /set bootstatuspolicy ignoreallfailures
bcdedit /set recoveryenabled No
bcdedit /set {default} bootstatuspolicy ignoreallfailures
bcdedit /set {default} recoveryenabled No
vssadmin delete shadows /for={volume} /oldest /all /shadow={ID of the Shadow} /quiet

After completing it’s preparation actions, Dharma .arrow ransomware proceeds to encrypt the files on the infected computer.

Dharma .arrow Ransomware – Encryption Process

Similar to other CrySyS ransomware variants, the Dharma ransomware virus also uses the AES encryption algorithm in order to encrypt the files on the compromised computer. This results in various different types of activities that happen including the system freezing for brief period of time. The .arrow variant of Dharma performs a scan of the following types of files and if it detects a match, the malware encrypts them:

“PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML. DOC .DOCX .LOG .MSG .ODT .PAGES .RTF .TEX .TXT .WPD .WPS .CSV .DAT .GED .KEY .KEYCHAIN .PPS .PPT .PPTX ..INI .PRFEncodedFiles .HQX .MIM .UUE .7Z .CBR .DEB .GZ .PKG .RAR .RPM .SITX .TAR.GZ .ZIP .ZIPX .BIN .CUE .DMG .ISO .MDF .TOAST .VCD SDF .TAR .TAX2014 .TAX2015 .VCF .XML Audio Files .AIF .IFF .M3U .M4A .MID .MP3 .MPA .WAV .WMA Video Files .3G2 .3GP .ASF .AVI .FLV .M4V .MOV .MP4 .MPG .RM .SRT .SWF .VOB .WMV 3D .3DM .3DS .MAX .OBJR.BMP .DDS .GIF .JPG ..CRX .PLUGIN .FNT .FON .OTF .TTF .CAB .CPL .CUR .DESKTHEMEPACK .DLL .DMP .DRV .ICNS .ICO .LNK .SYS .CFG”

After the .arrow file variant of Dharma ransomware has performed it’s encryption procedure, it immediately appends the .arrow file extension to the encrypted files by it, making them look like the following:

After encryption, the .arrow files cannot be opened via any software, because they key structure has been replaced with symbols from the AES encryption algorithm, used by Dharma ransomware, also known as Advanced Encryption Standard. It is a military-grade encryption, which if implemented properly can take years to decrypt if you do not know the decryption key. Despite this, security experts strongly advise victims not to pay, since you cannot trust that the crooks will recover your files and you should not finance the crooks into performing their malicious activities and spreading them further.

    Hi Vencislav,

    Recently our system has been compromised by the latest variant of this ransomware. We have been able to remove the virus, but up to know we have yet been able to decrypt the infected file. Our most important file is our sql database file, which contains our ERP database file. Can we engage on your service to restore / decrypt our file? Please let us know. Much appreciated. Thanks.

      Hello, santa

      I do understand that your sql database file has been encoded. Be advised that the .arrow ransomware is a variant of Dharma ransomware. The first variant of the ransomware infection, containing the file extension .dharma was decryptable via the following decryption instructions:

      https://sensorstechforum.com/remove-dharma-ransomware-restore-dharma-encrypted-files/

      However, i’ll have you know that the nasty crooks who are behind this malware, have developed it into several new variants, including the .java file extension and the .arrow one, by which your enterprise system is most likely infected. The bad news here is while the Rakhni Decryptor by Kaspersky found on the link above worked for the .dharma files variant of Dharma ransomware, the new variants have a patch against which the decrypter may not be able to work. I do understand that databases are more complex in their nature, so I would suggest that you try to recover the ERP database file by scanning the SQL database file, by using a data recovery program. You can recover at least some of the ERP files, if you are lucky. Other than that, the .arrow ransomware uses not one but two encryption algorithms – RSA and AES and factorization of the private RSA key can be used to recover it, but for that you would require the public one as I have found out and described in this article:

      https://sensorstechforum.com/restore-files-encrypted-via-rsa-encryption-remove-cryptowall-and-other-ransomware-manually/

      Ofcourse, the instructions in this article are for a virus that was discovered a while back and even with a powerful computer, the factorization process can take ages. And if the virus uses the AES encryption algorithm as well, the task becomes from impossible to double impossible. So the best advise that I have for you is to follow the No more ransom project – https://www.nomoreransom.org/en/index.html and wait for a decryptor to be released, while in the meantime check up on different data recovery software which can assemble fragments of your encrypted database and recover it. Ofcourse, since the database is a file, which i am assuming is large, your chances are not high, but you might wanna check for specific data recovery software that is able to recover SQL databases. Furhtermore, please be advised to learn how to safely store your databases to prevent such occurances in the future:
