Ransomware distribution method

Like most ransomware infections, Ordinal ransomware is typically distributed by email spam messages that contain malicious 7zip, 7z, rar, docx, and zip email attachments. Once the attachment is downloaded and executed it will spread the malware across the machine and begin its encryption process.

As the ransomware states in it’s note, the ransomware is also distributed by third-party downloads such as dubious or corrupt freeware, codecs, and updates.
