Lmas – Ransomware
Lmas is a malicious software functioning as typical ransomware. Michael Gillespie, the widely known malware researcher, very first discovered this new name in the DJVU ransomware family.
Lmas was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the encryption is successfully accomplished, the users are not able to get access to them. Lmas ransomware includes its own “.lmas” to all the encrypted files. For instance, the file “price_list.xls”, as soon as crypted by Lmas, will be titled as “price_list.xls.lmas”. Once the encryption is accomplished, Lmas puts its own distinct text document (_readme.txt) into all the folders that save the encrypted files.
The alert stated by _readme.txt asking for the random os very similar to the alerts offered by other ransomware hazards coming from the DJVU family. The warning basically indicates that the files have been encrypted and the only option to get access to it is to use a special standalone key. Regretfully, this statement is absolutely real.
The method to secure the files used by Lmas is not entirely researched. Nevertheless, there is no doubt that each computer owner may be issued an unique decryption key, which is absolutely unique. It is exceptionally difficult to recover the data without the suitable key in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Lmas infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have released the Lmas virus into the internet. In order to acquire the key and bring back the crucial information, the users are told to contact the frauds by means of e-mail or by telegram and to pay the ransom in the amount of $980.
The message also states that the people must get in touch with the Lmas authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so the people will get a 50% discount rate, for that reason, the ransom amount drops down to $490.
