While Sodinokibi ransomware has been in the news recently, technical details for that particular strain have been far less visible. Researched and written by Ravikant Tiwari and Alexander Koshelev. The Sodinokibi ransomware sample we analyzed was packed using a custom packer. Even after successful unpacking, the main Sodinokibi code does not seem to have much of a readable string.

Neither does it have any imports for system libraries and APIs, which means a static AV scanner that depends on a readable string and imported API table will have a hard time detecting it. API names and other required strings are decrypted during its runtime using the RC4 algorithm. To make the situation even more challenging for anti-virus software, most of the operations on strings are performed using a DJB hash of the string rather than the string itself.

Sodinokibi starts by building a dynamic import table and ensuring that this is the only instance running currently on the system with the help of mutexes. The code responsible for running the exploit first checks if the September 11, patch KB is applied on the machine.

This patch addresses multiple vulnerabilities mentioned below. If the patch is not detected, the ransomware proceeds to execute a or bit version of the shellcode depending on the platform architecture. We believe it tries to elevate its privilege by exploiting CVE If the system is not vulnerable and the process is still running as a limited user, it will use a RUNAS command to launch another instance with administrative rights and terminate the current instance if it is running with limited privileges.

The complete flow can be seen in the code below. It will try not to infect computers from the following countries based on the locale setting of the computer. After passing the pre-check it terminates the mysql. Interestingly, before wiping all the files inside this directory it overwrites the content with random bytes to make file recovery impossible.

It uses this to generate a shared secret, which will be used as the key for symmetric encryption algorithms AES and Salsa20 which are used to encrypt different kinds of data. Sodinokibi is shipped with two different public keys, one as part of JSON configuration and another embedded in the binary itself.

These public keys will be used to encrypt the locally-generated private key. Below we detail the steps included in the key generation and encryption process. Step 1. Generate a session private secret, random number and public key pair on the local machine. Step 3. Use the private key from Step 2 and the public key pk key value from JSON to generate a shared key and hash it to generate a symmetric key.

Step 5. Step 7. Figure 8: Encrypting the private key from step one using the attacker's public keys. Encrypting the private key from Step 1, using public key present embedded in the binary. Step 9. Repeat Steps 2 through 7 by using a different public key that comes embedded in the binary for Step 3.

Step Generate a shared key using the session public key generated in Step 2 and hash it to get another symmetric key for using in Salsa20 key generation. The simplified version of how the decryption process of the user files will look like the graph below. AddFileToIoCompletionPort also generates a unique Salsa20 key for each file that is to be encrypted and pass this Salsa20 key to the encrypting thread as part of structure containing other metadata that has to be written to file as well after encryption using lpOverlapped parameter of PostQueuedCompletionStatus Win API.

During enumeration it also create a ransom note file in all folders that are not in the exempted folder list. The encrypting thread takes care of reading the file contents, encrypting it, writing it back to the same file, writing metadata that contains encrypted session Private key the per file ECDH Public key and per file Salsa20 IV used for encrypting the files and then renaming it by appending with a randomly generated extension name.

File are encrypted using Salsa20 Chacha variant encryption algorithm inside EncryptAndWrite user function. After the encryption process is complete, the ransomware prepares the data to send to the control server. This data contains different fields from the JSON configuration, system information, and encryption keys.

Sodinokibi contains a template of its ransom note with placeholders for user-specific details. These placeholders are dynamically substituted with user-specific extension name, user id uid — see the table above for description , and key. The ransom note is placed in each directory excluding the whitelisted one. There is no free decrypter available for this ransomware and the only choice is to use the decryption service provided by the attackers, which can be accessed by following the instructions in the ransom note.

To protect against ransomware we recommend using an advanced anti-ransomware solution and maintain an updated anti-virus solution. All Acronis product are equipped with advanced anti-ransomware technology and can protect you against any such attack and minimize the risk of data loss.

Cyber protecton products like the personal solution Acronis True Image or business solution Acronis Backup come with the AI-based anti-malware defense Acronis Active Protection built in, and are therefore able to protect users against Sodinokibi ransomware.

Researched and written by Ravikant Tiwari and Alexander Koshelev Executive Summary Sodinokibi is likely being distributed by attackers affiliated with those that distributed the infamous GandCrab ransomware family, which is supposed to be retired soon according to the underground forum where GandCrab first appeared. Sodinokibi tries to avoid infecting computers from Iran, Russia, and other countries that were formerly part of the USSR.

Sodinokibi uses an Elliptic-curve Diffie-Hellman key exchange algorithm to generate and propagate encryption keys. Once it infiltrates a machine, it wipes out all of the files in the backup folder. Currently, the ransomware demands 0. They claim that this amount should be paid within four days or the ransom demand will be doubled. How it works The Sodinokibi ransomware sample we analyzed was packed using a custom packer. Initialization Sodinokibi starts by building a dynamic import table and ensuring that this is the only instance running currently on the system with the help of mutexes.

Salsa20, on the other hand, is used for encrypting user files. Generate another private and public key pair. Figure 7: Generating a symmetric key using a shared key Step 4.
