"x_misp_value" : "A couple of weeks ago, we observed the Necurs botnet distributing a new malware spam campaign with a payload combo that includes Trickbot and Nitol. Trickbot is a banking trojan that first appeared late last year targeting banks in Europe, UK, Australia and other countries. This trojan injects malicious code into a web browser process and siphons sensitive data when the victim visits a target banking website. The Nitol family is well-known for its distributed denial of service (DDOS) and backdoor capabilities."
