Teamo Ransomware – How Does It Work

Teamo ransomware is a virus created by someone with the nickname Zika. The malware is believed to be an EDA2 ransomware variant, since it’s main executable has the same name.

When an infection with Teamo ransomware takes place, the virus aims to perform various activities on your computer, starting with connecting to the command and control server to download it’s payload on the computer of the victim. It consists of the following files:

  • It’s main executable, named eda2.exe.
  • A randomly named .exe file.
  • It’s ransom note image.

The ransom note image has a ransom note demanding victims to contact Zika for payment. It is shown on the image below:

Text from image:

Tus Archivos Has Sido Encryptados
(Your files have been encrypted)
Tus archivos has sido encryptados, lo que sighifica que ya no puedes abrirlos. Debo decir que no existe manera que los podamos recoperar :(… Mentira, contactame. Zika
Your files have beeh encrypted, which means you can not open them any more. I must say there is no way that the recipes :(…
Lie, contact me. Zika
Atte. Your Friend Zika

After the malicious files of this infection have been dropped on the computer of the victim, the Teamo ransomware changes it’s ransom note image as a wallpaper and may attack the Windows registry editor of the infected computer, more particularly the Run and RunOnce registry sub-keys, located in:

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

In thos sub-keys, the Teamo virus may add value entries with data in them, poining to the malicious executables of the ransomware. This results in the virus files running automatically when you start Windows, so restarting your computer after infection with Teamo ransomware is not advisable.

In addition to modifying the Windows registry sub-keys, Teamo ransomware may also be configured to run a batch script as an administrator on the victim’s computer. This script may run a command as an administrator in Windows Command Prompt, which eventually results in deleting the volume shadow copies of the infected computer. The commands which may be executed with different parameters without the victim noticing are the following:

→ vssadmin
bcedit

  • Images.
