What is Suri ransomware? And how does it execute its attack?

Suri ransomware is a file-encrypting virus that encrypts important data in a computer. Encrypted files by Suri ransomware can be easily identified as the files have the .SLAV extension. The instant it infiltrates a system, it drops a file named Suri.exe which is the malicious payload of Suri ransomware.

After dropping its malicious payload into the system, Suri ransomware executes a series of changes in the system. It also employs a data harvesting module which is used to obtain information from the system and uses it for stealth protection. The stealth protection module is the one that prevents any program in the system from interrupting the ransomware attack. Moreover, Suri ransomware also alters some entries in the Windows Registry so that it can automatically run on every system startup. After that, it scans the computer for its targeted files and encrypts them using a sophisticated encryption algorithm. Once the encryption is completed, it adds the .SLAV extension to every affected file and displays a picture containing the ransom note stating:

“O no, tutti i tuoi file personali sono stati cryptati

Come faccio a decryptarli?

Ciao utente, tutti i tuoi file personali sono stati cryptati.Non si torna più indietro ormai. Tgliendomi condSurierai tutti i tuoi file. Tutti i tuoi file personali verrano decryptati e io mi auto elimino. Semplice! Invia una somma di 100 Euro in bitcoin all’indirizzo sottostante io chiave pubblica. Riavviando o altro non risolvi nulla.

Ora forse ti chiederai come fare. Perché ?

Solo io sono in grado di decryptare tutti tuoi file e solo io ho la Dopo aver pagati che succede ?

Tutti i tuoi file personali verrano decryptati e io mi auto alimio”

Here’s a rough English translation of the ransom note:

“Oh no, all your personal files have been encrypted

How can I decrypt them?

Hello user, all your personal files have been encrypted. Can’t go back now. You will give all your files to me. All your personal files will be decrypted, and I will delete them. Simple! Send a sum of 100 euros in bitcoins to the address below and public key. Restarting or else will not solve anything.

Now maybe you’ll wonder how to do it. Why?

Only I can decrypt all your files, and only I have the key. After paying what happens?

All your personal files will be decrypted, and I will give them back.”

If your computer is infected by Suri ransomware, the best thing you can do is not to pay the ransom but to try alternative ways to restore the encrypted files. But before you perform file recovery, you have to kill Suri ransomware’s process from your computer first.

How does Suri ransomware proliferate?
