MAGICSPELL 악성코드 탐지: UAC-0168 해커, 우크라이나의 나토 가입 문제를 피싱 미끼로 사용해 목표 공격 수행

CERT-UA 연구원들은 최근에 우크라이나 세계 대회 웹사이트의 영어 버전의 사기성 복사본을 발견했습니다. https://www.ukrainianworldcongress.org/ 위조된 웹 자원은 열릴 경우 감염 체인을 유발하는 몇 가지 DOCX 문서를 포함하고 있습니다. 공격 체인의 결과로, 해커들은 감염을 더욱 확산시키기 위해 다운로드, 해독 및 다른 로더를 실행하려는 MAGICSPELL 페이로드를 배포할 수 있습니다. 식별된 악성 활동은 UAC-0168로 추적되고 있습니다.

UAC-0168 표적 공격 분석이 CERT-UA#6940 경고에서 다뤄졌습니다.

2023년 7월 5일 CERT-UA 연구원들은 최신 CERT-UA#6940 경고 를 발행했으며, 이는 UAC-0168 해킹 그룹에 귀속된 표적 적대적 활동을 다룹니다. 이 악성 캠페인에서, 위협 행위자들은 피해자로 하여금 악성 DOCX 파일을 열고 감염을 유발하도록 유도하기 위해 우크라이나 세계 대회 웹사이트의 정품 버전의 사기성 복사본을 활용합니다. 위조 웹 자원은 다가오는 NATO 정상회담과 우크라이나의 NATO 회원 자격과 관련된 제목을 가진 두 개의 DOCX 문서를 포함하며, 둘 다 악성 URL 주소와 UNC 경로를 가진 RTF 문서를 포함하고 있습니다.

위협 행위자들은 HTTP 및 SMB 프로토콜을 통해 통신을 설정합니다. 상기 언급된 DOCX 파일을 열고 관련 취약성을 성공적으로 악용하면 .chm 파일과 HTM 및 웹 아카이브 파일을 포함한 일련의 악성 파일을 다운로드 및 실행하게 되며, URL 및 VBS 파일이 감염을 더욱 확산시킵니다. 마지막으로 해커들은 SMB 자원에 위치한 EXE 및 DLL 형식의 다양한 파일을 실행할 수 있습니다.

조사 기간 동안, 사이버 보안 연구원들은 손상된 시스템에 다른 악성 실행 파일을 배포하고 지속성을 유지할 수 있는 MAGICSPELL 로더로 식별된 ‘calc.exe’ 파일을 공개했습니다.

공격자들이 활용한 SMB 자원 분석 결과 전 세계 30개국에 분포된 195개의 IP 주소가 나타났으며, 대부분이 VPN 서버와 연구 기관에 속해 있습니다.

CERT-UA에 따르면, 우크라이나의 NATO 회원 자격이라는 주제와 우크라이나 세계 대회의 이름을 피싱 미끼로 사용함으로써 UAC-0168의 최근 공격이 7월 11-12일 리투아니아 빌뉴스에서 열릴 예정인 NATO 정상회담과 연관이 있다고 밝혔습니다.

우크라이나에 대한 UAC-0168의 최신 공격 탐지하기
