File encryption virus belonging to the id variants has been let loose to infect unsuspecting user. The malware is named JuicyLemon, and it belongs to the “id” ransomware viruses. The cyber-criminals behind JuicyLemon use a strong cipher to encode files on infected computers and for their safe decoding, they demand around 2.5 BTC, which is approximately 1000 euros. The virus uses a 7 number file extension added after every encrypted file which is a custom identification of the infected computer. Even though at the moment direct decryption is impossible we strongly advise users not to pay the ransom and try to restore their files using alternatives like the methods after this article until a decryptor is released.

JuicyLemon Ransomware Strategy of Infection
So far, as reports by researchers indicated, JuicyLemon is spread via the notorious and extremely effective Angler Exploit Kit. However, the cyber-criminals behind it may use other methods as well.
To successfully penetrate the defenses of the systems it infects, JuicyLemon may typically act on the same escalated privilege level as the user. Once it obtains this privilege by most likely executing obfuscated processes that slips past any real-time antivirus shields.
All of those may be distributed via spam e-mails featuring the web links along with a message that convinces users to click on them, for example:
Another way of spreading may be on spam posts or comments on social media, like facebook, twitter or another service.
It is also not excluded that the malicious .exe file of the ransomware may be directly downloaded on the user PC by arriving in an archive downloaded from e-mails, suspicious third-party websites, and others.
JuicyLemon Ransomware – Activity
Once its malicious payload is dropped on the infected computer, it may be located in one of the following Windows folders, under the following names, for example:
Typically, JuicyLemon may create registry entries which will allow it to run on Windows startup. This happens by targeting the following Windows registry keys:
After doing so, the ransomware may delete the shadow volume copies of the infected computer, eliminating any backup if present. This can happen by executing the vssadmin command with one of its parameters, for example:
JuicyLemon ransomware uses a strong cipher to encrypt the user’s files. It may look for files containing the most widely used file extensions and encode them:

After the encryption process is complete, JuicyLemon may delete itself to prevent malware analysis. It leaves the encrypted files with a file extension containing unique number, the letters “id”, along with an e-mail address, and a bitcoin payment address, for example:
→ New Text Document.email@example.com_email2_provectus@protonmail.com_BitMessage_BM-NBRCUPTenKgYbLVCAfeVUHVsHFK6Ue2F
Before deletion the ransomware may send different information, such as the decryption key for the encoded files to its remote server, reported by Bleeping Computer researchers to be the following:
It also drops a text, file called Read me now !.txt ,which contains the following ransom note:
→ “Hello! We inform you that all, absolutely all of your files are encrypted!
