What is Navi ransomware? And how does it carry out its attack?

Navi ransomware is yet another variant of Scarab ransomware. It seems that these variants of Scarab ransomware keep coming and there seems to be no end to it. This new strain uses the .navi extension in marking the files it encrypts. Based on the analysis conducted by security experts, there is not much improvement in this new variant as it shares the same code with other new versions of Scarab. The only notable changes are the extension used and its ransom note.

Navi Ransomware

Security experts have mulled over the recent happenings where Scarab has continuously released variants and came up with two possible explanations why the creators of this dangerous ransomware group keep doing so. First, it could be that these crooks are incrementally creating several versions in order to track different campaigns. Second, it could be that they are also offering customization services or have provided the source code on underground markets such as the dark web – this allows other threat actors to create their very own ransomware infection.
Once it is able to infiltrate a computer, it will drop its malicious payload on the system folder like:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%

After it drops its malicious payload, Navi ransomware will begin to execute its attack by adding more malicious files. These malicious files may be used to repress or launch system processes that allow the crypto-malware to stay undetected. It may also modify some registry keys and sub-keys in the Windows registry which allows it to run on every system startup. Once these changes are applied, it begins the encryption process using a strong encryption algorithm. Following file encryption, it adds an email address as well as the .Navi suffix to each one of the encrypted files. It then releases its ransom note in a file named “HOW TO RESTORE INFORMATION.txt” which contains the following message:

“Hello! To decrypt your files, send your personal ID to the next e-mail addresses:
[email protected]
[email protected]
Do not try to decrypt files by yourself to avoid damage of files!!!
Your personal ID:
+4IAAAAAAAA***TXLSrh4Pk”
