What Is Lmas?
Lmas is the name of a ransomware virus, whose main purpose is to get users to pay a hefty ransom fee if they want to use their files once again. The main goal of infections, like Lmas, is to get into your computer and encrypt your files, using the .lmas extension. The files are likely encrypted with AES encryption algorithm, which is very likely used by other viruses like this one because the Lmas Ransomware belongs to the STOP/DJVU family of infections.
In case you have become a victim of this nasty infection, we would strongly recommend that you read this article as it will help to learn more about this virus and how to cope with it adequately.

Lmas Virus – More Information
Lmas virus is a STOP/DJVU ransomware variant, just like Reig, Ygkz and Plam viruses. It’s main purpose is to scramble your files and extort you into paying BitCoin to the cyber-criminals who are behind this threat.
The Lmas can infect your computer via two main means – e-mail and if you have downloaded some fake executable program online. If it infects your machine by e-mail, then the Lmas will likely use spam e-mail that pretends to be something important. The e-mail may carry an attached file that poses as a legitimate document but actually is the virus infection file. Such documents often pose as invoices and other forms of important files.
If the Lmas virus has been uploaded on some site and you happen to have downloaded it, it may pretend to be a crack, patch, keygen, portable app, or some other similar executable file that triggers the infection.
When the Lmas ransomware infects your computer, it may connect to a remote IP address and download its virus files. They could reside in the following Windows directories:
- %LocalLow%
- %Temp%
- %System%
- %system32%
- %Roaming%
- %ProgramData%
- %Windows%
- %Local%
- %AppData%
The Lmas also drops its _readme.txt ransom note file, that may appear with the following message directed towards victims:
When the virus is already active on your computer, it may assume administrator permissions and set up the following malicious activities without your knowledge:
- Connect to the command and control server of the criminals.
- Set up registry values in the Run and RunOnce Windows Registry sub-keys.
- Run with administrative permissions.
- Obtaining read and write privileges.
- Check if it has previously infected your machine.
.lmas Files
This virus may encrypt your files, using the .lmas file extension and the AES encryption algorithm. The main files targeted to be encrypted are the following:
- Video data.
- Image file types.
- Database files.
- Various archive types.
- Anything in USB or other external drive.
- Backed up files.
- Document files.
- Audio file formats.
Since this is a STOP/DJVU ransomware variant, there can be two ways to recover your files. After encryption, this ransomware releases either online or offline decrypt keys. If you key is an offline key, then you may be in luck, because these form of decryption keys can be easier to decode for free.
