Ransomware remains one of the most pervasive and damaging types of malware. Geometrical Ransomware is a recent addition to this menacing category, known for its sophisticated encryption techniques and devastating impact on both individuals and organizations. This article delves into the nature of Geometrical Ransomware, its modus operandi, detection methods, and provides a comprehensive guide for its removal and prevention.
What is Geometrical Ransomware?
Geometrical Ransomware operates like typical ransomware, infiltrating systems through various vectors such as phishing emails, malicious attachments, or compromised websites. Once inside a system, it swiftly encrypts files using strong encryption algorithms, rendering them inaccessible to users. The attackers then demand a ransom payment, usually in cryptocurrencies like Bitcoin, in exchange for decrypting the files.
Actions and Consequences
The consequences of a Geometrical Ransomware attack can be severe. Victims often find themselves unable to access critical data necessary for daily operations or personal use. This can lead to significant downtime for businesses, financial losses, and in some cases, irreparable damage to reputation and customer trust.
The text of the threat in its original Korean language is:
‘geometrical ransomeware. v1
기하학적 랜섬웨어. v1
made by j.d.h.
opps! 당신의 모든 파일들은 암호화 되었습니다.
군사 수준의 알고리즘을 풀어 당신의 파일들을 복구하는 방법은 복구키를 구입하는 방법뿐입니다.
300$를 보내야 합니다.
당신의 해독 키는 1736-29467-28ke-dj72 이며 이를 입력하여 확인 후 복호화 키를 구입 가능합니다.
바이러스 파일을 삭제시키거나 백신을 키지 마십시오.
안티 바이러스가 업데이트되고 바이러스가 자동으로 삭제되면 돈을 지불했더라도 복구가 불가능 합니다. 하루가 지날 수록 지불해야 하는 금액은 배가 되며, 매일 100개의 파일들이 삭제됩니다.
