Locdoor ransomware
Locdoor ransomware is a cryptovirus causing a short ransom note to notify its victims about the encryption of their files. In this text file, you can find more details about the attack.
Locdoor ransomware is a fraudulent crypto infection that starts its activity by claiming your homepage was encrypted. Supposedly, if you pay the demanded $0.10 ransom, virus developers are going to send you a decryption tool. However, the particular ransomware[1] is not encrypting your files. Alternatively known as DryCry, the virus just locks your computer screen and drops various items on the desktop. After convincing its victims that the device is locked by the cryptovirus, ransomware displays a specific note about the infection on the screen called Notice_readme.txt. Also, Locdoor displays a browser window with the instructions for your further actions. This HTML window displays even more details about the alleged decryption tool and cryptocurrency payments. The email address provided: sealocker@daum.net.

Locdoor ransomware is not encrypting your files, as typical ransomware, so there are numerous speculations claiming that the program is still in development. However, this virus replaces some of the file extensions with the appendix .door. The ransom note claims that this infection locks your data and you need to pay the ransom in cryptocurrency worth $0.10. The virus developers demand you to pay in Bitcoin at the address localbotcoins.com and send a photo to sealocker@daum.net. 

However, researchers[2] do not advise victims of this cyber threat to contact its developers in any way. Besides, paying the ransom is not useful since there is no encryption procedure initiated by the virus. Developers are seeking just to lure people with the small ransom, but there is no doubt that people behind the threat are not trustworthy in any way.

Locdoor/DryCry ransomware displays the following ransom note:

Your computer's files have been encrypted to Locdoor Ransomware! To make a recovery go to localbitcoins.com and create a wallet and send a bit coin to the $ 0.10 value to the address Then, send your verification picture to and we will send you the recovery tool!

The other version of the ransom note: 

Bit coin is only allowed on localbitcoins.com! Send a bit coin of $ 0.1 value to at localbitcoins and send it to sealocker@daum.net with a certified photo! We will then email the recovery tool! Thank you! to Buy Recovery Tools.txt

It is important if you want to avoid any significant damage caused by this threat in the future. Keep in mind that ransomware can access important data and change system settings on your device immediately after the infiltration. Because of this fact, we do not recommend initiating Locdoor/DryCry ransomware removal manually.

A malicious script is spread via spam emails

Silent infections can be spread in various ways. The most common for ransomware is spam email attachments. The malicious script of the ransomware can spread on your system from an insecure email that you open unknowingly. A payload dropper can be designed to install the direct malware script when you download and open a file attachment from an email. This malicious intruder can be this ransomware. 

There is an opportunity to get various other malware like Trojans[3] which are designed to open backdoors or spread the ransomware directly on the device. You are downloading the file and installing malicious programs on the device at the same time. This is a silent infection you have no idea about this background process.

You can avoid these cyber infections if you pay more attention to processes happening on the device. If you are not waiting for an email, be aware that not every one of them is safe. Do not download suspicious attachments and try to scan those files before opening them on the computer.
