안녕하세요 처리의블로그입니다.
요즘 유행하는 악성코드라고 하면 단연 랜섬웨어(Ransomware)라고 할 수 있는데요.
컴퓨터를 잘 아는 사람도, 모르는 사람도 한순간에 당하게 되는 랜섬웨어!!
랜섬웨어란? (출처 : 나무위키) |
몸값을 뜻하는 Ransom과 악성 코드를 뜻하는 Malware의 합성어이며, 사용자의 동의 없이 시스템에 설치되어서 무단으로 사용자의 파일을 모두 암호화하여 인질로 잡고 금전을 요구하는 악성 프로그램을 말한다. 일반적인 PC는 물론 서버, 모바일, DSLR#에서까지 현존하는 거의 모든 운영체제에서 활동한다. 랜섬웨어 종류에 따라 백신 프로그램이 사전에 랜섬웨어의 암호화를 차단하기도 한다. |
일단 랜섬웨어가 실행되면 내 PC의 대부분의 문서나 파일들이 암호화가 되게 되는데, 일부 랜섬웨어들은 복호화 툴이 공개되어 있어서 내 컴퓨터에 암호화 된 파일들을 다시 원상복구 시킬 수 있습니다.
그래서 일단은 지금 감염 된 랜섬웨어가 어떤 이름의 랜섬웨어인지를 아는거 부터가 중요한데요.
한국랜섬웨어 침해대응센터에서 제공하는 사이트가 있습니다.
해당 사이트에서는 2가지 방법으로 랜섬웨어의 종류를 확인하고 있습니다.
- Ransom Note
랜섬웨어에 감염 후 생성되는 결제 안내 파일을 업로드 후 해당 파일을 식별하여 감염된 랜섬웨어의 정보를 알려줍니다.
- Sample Encrypted File
랜섬웨어에 감염되어 암호화된 파일을 업로드 후 해당 파일을 식별하여 감염된 랜섬웨어의 정보를 알려줍니다.
현재 2022년 9월 23일 기준으로 1,078개의 랜섬웨어를 탐지할 수 있다고 하니 참고하시기 바랍니다.

테스트로 저는 LockBit 3.0 과 GandCrab 5.2 버전, 총 2가지 샘플을 준비해습니다.
모두 랜섬노트(Ransome Note)로 테스트를 진행하였고 결과는 아래와 같습니다.
- LockBit 3.0 랜섬노트 검사
최근 유행하고 있는 락빗 3.0(LockBit 3.0) 랜섬노트로 검사하게 되면 LockBit, LockBit 3.0 종류의 랜섬웨어 종류가 확인됩니다. 아쉽게도 락빗 3.0 랜섬웨어는 현재까지 복호화 방법이 없다고 알려줍니다. (This ransomware has no known way of decrypting data at this time) 그래도 LockBit 랜섬웨어 대해 궁금한점이 있으면 확인하라고 링크를 보여주긴합니다.
- GandCrab 5.2 랜섬노트 검사
지금은 유포되지않지만 예전 핫했던 랜섬웨어인 갠즈그랩 5.2 랜섬노트로 검사를 진행했더니, 복호화가 가능하다고 표기가 됩니다. 그럼 하단 링크를 통해 복호화를 진행하면 됩니다.
ID 랜섬웨어 사이트에서 클릭한 링크로 넘어오게 되면 복호화툴을 다운로드 할 수 있는 사이트로 이동시켜주며, 해당 툴을 다운로드 받아 복호화를 진행하면 됩니다.
이상 랜섬웨어 종류를 알아보는 사이트에 대해서 설명드렸습니다. 궁금하신점은 댓글로 부탁드립니다.
최근에 감염되신 분들은 대부분 신규 랜섬웨어일 가능성이 높아서 복호화 툴이 공개되는 경우는 드물긴하지만, 그래도 혹시 모르니 이 사이트를 통해 복호화툴을 얻을 수 있다면 의미가 있다고 생각합니다.
