Retadup is a malicious worm—self-replicating malware—that surreptitiously uses a computer’s processor to mine cryptocurrency, which generates money for the operators. It’s also able to run other types of malware, such as ransomware, and is commonly spread via attachments, file-sharing networks and links to malicious websites.
Retadup had infected at least 850,000 computers. While most of these were in Latin America, it had also spread to the US and Russia.
