Another notable change in this new ransomware variant is that, instead of encrypting files using the AES cipher, it modifies the targeted files’ structures by inserting the word “HACKED!!!!!”. Annabelle 2.1 ransomware is not as dangerous as its predecessor since its targeted data is not encrypted by a key that is usually stored in a remote Command and Control server. However, that does not make it harmless either as it can still corrupt files.

Once it starts its attack on the infected computer, it will modify various system settings in order to achieve persistence. This includes modification in the Windows Registry allowing it to automatically execute its attack on each system boot.

파일을 복구를 할려고 해도 데이터가 모두 파고I 되어 파일을
1.일을 복구할 방법을 없습니다

  1. S 웨어는 SHA1 알고리즘 으로 파일을 모두 파고I 함니다.”

“Your computer files are all Annabelle 2.1 files.
