**IMPORTANT UPDATE: March 14, 2024**

**StopCrypt: Most widely distributed ransomware now evades detection** [**https://www.bleepingcomputer.com/news/security/stopcrypt-most-widely-distributed-ransomware-now-evades-detection/**](https://www.bleepingcomputer.com/news/security/stopcrypt-most-widely-distributed-ransomware-now-evades-detection/ "www.bleepingcomputer.com")

 **IMPORTANT UPDATE: April 12, 2022**  

**According to information previously provided on the Emsisoft Forum, they no longer have any method to decrypt STOP (DJVU) Ransomware unless the encryption occurred before the 29th of August 2019.**That means there is **no way to decrypt files** with **Online-ID and some recent forms of STOP (DJVU)**. However, victims should at least keep trying the [**Emsisoft Decryptor**](https://www.emsisoft.com/ransomware-decryption-tools/stop-djvu "www.emsisoft.com") if infected with an OFFLINE KEY.

    STOPDecrypter supports and will only attempt to decrypt files if they were encrypted by one of the known STOP (DJVU) OFFLINE KEY's retrieved by Demonslay335 and embedded in his decrypter. The OFFLINE KEY is a hard-coded key that is used if the malware failed to get an ONLINE KEY from it's command and control servers while you were online at the time the ransomware encrypted your files. Each variant extension only has one OFFLINE ID.

    If STOPDecrypter indicates it "skipped" any files(did not decrypt), then they were encrypted by an ONLINE KEY, not by any of the OFFLINE KEYs listed in the decrypter OR a newer version of the ransomware. ****

    If the decrypter does not work on all files with the OFFLINE KEY, then it is possible the malware was run multiple times, and was able to contact and get an ONLINE KEY from it's command server. That means it is possible for a ransom note to have an OFFLINE KEY and a file to be encrypted with an ONLINE KEY. The ID that corresponds to which key a file was encrypted with is embedded in the file itself.

    If you were infected with both .karl and .nesa variants that means you were infected more than one time and most likely will have both ONLINE and OFFLINE KEYS. However. the .karl variant is not decryptable at this time.
