  • %AppData%
  • %Temp%
  • %Local%
  • %Roaming%
  • %Common%
  • %{UserProfile}%
  • %System32%

After creating these executables, BitStak could use the Windows Registry Editor to add harmful entries in it. This is likely done to so the virus can run on Windows boot and start encrypting files. The keys that could be targeted by BitStak include;
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
When the ransomware starts with the system boot, it may try to encrypt the following folders;

  • %Program Files%
  • %Program Files (x86)%
  • %AppData%
  • %Roaming%
  • %Documents%
  • %Downloads%
  • %Videos%%
  • %Music%
  • %Pictures%
  • %Desktop%

BitStak reportedly seeks out and encrypts files of the following type (if they are present of the infected system);
.txt, .doc, .exe, .dat, .bat, .vb, .zip, .cfg, .flv, .php, .com, .db, .bin, .reg .7z, .rar, .jar, .mp3, .wav, .save, .mp4
As if that wasn’t enough damage, BitStak also adds a file extension called “.bitstak” that changes the original names of encrypted files with an alpha-numerical sequence. That way “New Text Document.txt” becomes “Z8932h3.bitstak.”
After that, the infected PC’s desktop wallpaper would be changed with a picture stating;

“Your all files are locked and encrypted with a strong encryption method. You cannot get your files back without paying. We expect you to make a payment in 3 days, or your files will be permanently deleted.
