Teamo ransomware, also known as Zika ransomware, is a new cyber threat created using the Hidden Tear open source platform. This ransomware seems to target Spanish-speaking users based on its ransom note which is written in Spanish. However, that does not mean that users who aren’t Spanish are safe from this threat as its uses a widely-used distribution in spreading its infection. Teamo ransomware is even categorized as a severe threat by security experts since there is no way to recover the encrypted files unless a decryption key is available which is safely tucked away on the ransowmare’s Command and Control server managed by the crooks behind this threat.
Once Teamo ransomware invades your computer, it will launch a connection to its Command and Control server and then start to scan the entire drive of the computer looking for files to encrypt. This ransomware encrypts important files, especially the user-generated ones such as audio, video, images, documents, configuration files, and other file formats. During the encryption, appends the .teamo extension on each of the targeted files and drops its ransom note named Hello Hi Hola como sea jaja.txt which is placed on the desktop of your computer. Here’s the content of the ransom note written in Spanish:
“Tus Archivos Han Sido Encryptados
(Your Files Have Been Encrypted)
Tus archivos han sido encryptados, lo que significa que ya no puedes abrirlos. Debo decir que no existe manera que los podamos recoperar  … Mentira, contactame. Zika
Your files have been 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.”
And here’s the ransom note translated to English:
“Your files have been 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.”
It is assumed that cyber crooks might try to improve Teamo ransomware to make it even stronger than it already is. Security experts also suspect that the crooks behind this ransomware might even add a Trojan module to allow them to spy on the victims and take control of the infected computer.
Even though there is no way for you to recover the encrypted files using their shadow volume copies, fear not for you can still use any backup copies of the affected files if you have them and if you don’t, you just have to eliminate Teamo ransomware first and then wait until a free decryptor is available.
How does Teamo ransomware spread?
Teamo ransomware spreads as a malicious executable file named eda.exe which is distributed on spam emails. The malicious email is disguised as something important to lure users into opening the email and downloading the attachment.
