Emsisoft Decrypter for Ims00rry

The Ims00rry ransomware encrypts files using AES-128, and does not add an extension. Instead, the text "---shlangan AES-256---" is pretended to the file contents. The victim is asked to contact the criminals on Telegram @Ims00rybot.

The ransom note "README" contains the following text:

I am sorry!!!

My friend. I want to start my own business, but i have no money.

All your files photos, databases, documents and other important are encrypted with strongest encryption and algorithms RSA 4096, AES-256.

If you want to restore your files payment and write to Telegram bot

Eris Ransomware

Eris Ransomware


Virustotal

This is a new ransomware.  Sample is allowed to run in a sandboxed environment.  Encryption is fast as it encrypted almost all of my documents in drive C: in under a minute the sample was running.

Removal is easy, just do a full scan with an updated antivirus/antimalware (refer to virustotal.com for list of programs that can detect Eris ransomware).

Decryption is another story.  Although I've seen may sites with instructions on how to decrypt Eris, I doubt if any of them really works.

Ransomware Readme

Original document filesize is reduced to zero byte after encryption

Notes:  

  • Ransomware sample is detected by Kaspersky Security Cloud.  Sample was tested with AV disabled
  • AppCheck wasn't able to detect the encryption
  • After the test, Recuva failed to recover any encrypted documents

Free Ransomware Decryption Tools

Here is a list of ransomware decryption tools provided by antivirus developers.  It's sad that decryption tools can't keep pace with the growing number of ransomware.
