2000USD Ransomware is a malicious software that encrypts files on a victim's computer and demands a ransom of 2000USD in exchange for the decryption key. This type of ransomware typically infects computers through phishing emails, malicious websites, or software vulnerabilities. Once the ransomware is executed, it scans the victim's files and adds a specific file extension, such as .2000usd, to each encrypted file. This makes it impossible for the victim to access their files without the decryption key.
