DETECTION OVERVIEW

TLS Connection to a Suspicious Domain

Risk Factors

Attackers frequently establish websites that are designed to distribute malware or collect information from victims. The domains of known malicious websites can be included in threat intelligence, which is a collection of information curated by the security community. Network clients that communicate with a suspicious domain should be investigated. These clients might be vulnerable to machine-in-the-middle, phishing, or pharming attacks, which could result in the exposure of information.
