Countermeasure: To protect against Zeus and similar attacks, ensure you have updated antivirus software, regularly update your operating system and applications, and avoid downloading attachments or clicking on links from unknown sources.
Emotet: Emotet was a Trojan that often spread through phishing emails containing infected attachments. It could then download other malicious payloads like ransomware onto the victim's system.
