The Karo Ransomware is a ransomware Trojan that is used to attack computer users by taking their data hostage and then demanding the payment of a ransom from the victim. The Karo Ransomware is mostly delivered using corrupted email attachments, contained in spam email campaigns. These email messages will contain Microsoft Word documents, which use corrupted macros to download and install the Karo Ransomware onto the victim's computer. The Karo Ransomware is a variant of EDA2, an open source ransomware engine that was made available to the public in 2016, allowing con artists to create ransomware Trojans easily and carry out attacks.
