Tilde Ransomware – How Does It Replicate

There are several methods by which cyber criminals may distribute this virus all over the web. They include a huge investment into the latest tools that bypass standard OS defenses:

  • Program obfuscators.
  • Exploit kits.
  • JavaScript.
  • Spam bots or spamming services.
  • File joiners.

All of the different tools may be used to spread the virus via e-mail. One method of e-mail attacks is undertaking massive spam campaigns to infect as many users as possible. One of those e-mail subjects may be a free upgrade or a promise of anything for free. Users have also reported e-mails from banking institutions claiming their accounts have been suspected. Most e-mails use deceptive tactics just to get users to start opening the malicious e-mail attachments or URLs which can infect their computer via different combinations of the abovementioned malicious tools.

Malware attacks by Tilde ransomware may also be targeted against specific organizations by using spoof e-mails. This means that the black hat hackers may pretend to be someone from the company and send an e-mail address to the local e-mail server to infect computers in the local area network of the company like seen in the TV series Mr.Robot.

Some blackhats may also use the services of ad-supported applications, like browser hijackers which may cause direct redirects to malicious URLs if paid to do so.

Tilde Ransomware – In-Depth Analysis

After Tilde has successfully infected the computer of its victim, it may create one or more malicious files in several usually targeted Windows Folders:

commonly used file names and folders

The files may have different names, ranging from completely random to names appearing like legitimate Windows processes, such as svchost.exe, for example.

As soon as it has made the malicious files, Tilde ransomware may immediately start encrypting data and create registry values so that it runs every time you boot Windows, They may be located in the following keys:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Tilde Ransomware may begin to scan for a wide variety of file types, primarily associated with videos, music, photos, databases, virtual drives, remote drives and other files. After it detects the file extensions it is looking for; Tilde encrypts them using a very strong AES encryption. The files can no longer be opened after encoding with any software. They are appended the .~ file extension, and they may look like the following example:


After encryption, the Tilde Ransomware drops the following files containing its ransom note:

C:\Documents and Settings\Default User\Desktop\_RECOVER_INSTRUCTIONS.ini
C:\Documents and Settings\Default User\Templates\_RECOVER_INSTRUCTIONS.ini
C:\Documents and Settings\Local\Temp\Simple_Encoder\img.bmp

These files have the ransom note as a text .ini file and a .bmp image. Tilde Ransomware may modify the following registry key to change the wallpaper to its ransom note:

In the key:
HKEY_CURRENT_USER\Control Panel\Desktop
The value string:
“Wallpaper”=” C:\Documents and Settings\Local\Temp\Simple_Encoder\img.bmp”

The ransom note has the following text:

→ “All your system is encrypted.
All your files (documents, photos, videos) were encrypted.
It’s impossible to get access to your files without necessary decrypt key.
All your attempts to solve problem yourself will be unsuccessful!
We suggest you to read some articles about this type of encryption:
