IcedID Infection Activity: Traffic & Other Indicators with Brad Duncan
January 13, 2022 @ 9:00 am - 10:00 am EST
About this event
Also known as Bokbot, IcedID is one of many families of malware distributed through malicious spam. In this webinar, Brad reviews two email-based distribution campaigns regularly distributing IcedID since November 2021. He reviews recent examples of IcedID infection traffic and reveals indicators that can be identified through Suricata-based signatures. Many prominent malware families use encrypted HTTPS for post-infection command and control (C2) traffic. This HTTPS traffic often uses self-signed certificates that have unusual or unique certificate issuer data. Understanding this and other traffic characteristics can help security professionals quickly identify IcedID. Our goal is to stop these infections before they lead to more dangerous activity like ransomware.
