Almost Half of Malware Samples Communicate Direct to IP

Description
Analysis of 4 million dynamic malware reports reveals that 45.32% of malware samples with command-and-control activity establish direct-to-IP (D2IP) connections, bypassing DNS entirely and evading DNS-based security defenses. D2IP traffic accounts for 23.17% of all C2 connection attempts. This behavior is observed across diverse threats including Phorpiex ransomware droppers using hard-coded IP addresses, persistent data exfiltration campaigns employing obfuscated HTTP GET requests, SectopRAT targeting educational institutions with in-browser proxy capabilities, and IoT botnets like Mozi and Boatnet propagating through P2P networks. The research introduces zero trust IP (ZT-IP), a network-level enforcement approach that verifies whether outbound connection destinations were previously sanctioned by DNS responses, effectively blocking malicious D2IP communications that traditional DNS-based security controls cannot detect.
