So got hacked and got the following.

 

.arrow ransomware virus today.  From what i have found is no way to decryption this.  User had Carbonite back up so running a restore.  

 

Hacker used RPD and got in.

 

They left the following files.

 

Comb1.bat

Mouse Lock_v22

processhacker-2.39-setup

unlocker-set (1)

 

If you would like me to post what was in the bat files let me know maybe it will help out.

 

User had Webroot on server and found the following 

 

1.1.exe Found in 4 different places

NS.exe

Processhacker.sys

 

It seems the hacker did this and we are not finding anything else on the server,  Do you thinkj we should be fine to just restore and delete all .arrow files?  Does a reinstall of the OS need to be done on this server?  Any help would be great!

I would honestly nuke the box and reinstall/resetup everything if a hacker got in depending on what type of server this is.

 

Deleting the .arrow is one thing but you don't know what else they hacker could have left behind.

 

Reinstall > Resetup > Restore backup files.

 

Also do you have RDP 3389 opened to the world to your server? You need to lock that down.

Any files that are encrypted with Dharma (CrySiS) Ransomware will have an <id>-<id with 8 random hexadecimal characters>.[<email>] followed by the .dharma, .wallet, .onion, .zzzzz, .cezar, .cesar, .arena, .cobra, .java, .write, .arrow or .bip extension appended to the end of the encrypted data filename.
.id-A04EBFC2.[bitcoin143@india.com].dharma
.id-480EB957.[legionfromheaven@india.com].wallet
.id-EB214036.[amagnus@india.com].zzzzz
.id-5FF23AFB.[Asmodeum_daemonium@aol.com].onion
.id-01234567.[gladius_rectus@aol.com].cezar
.id-01234567.[btc2017@india.com].cesar

Dharma (CrySiS) with the .arrow extension is not decryptable without paying the ransom and obtaining the private RSA keys from the criminals.

There is an ongoing discussion in this topic where victims can post comments, ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.

Thanks
