Picus Security Details T1018 Remote Service Discovery Attack Technique
Picus Security's analysis details the T1018 Remote Service Discovery technique, used by attackers to map networks before performing lateral movement to achieve objectives.
Cybersecurity firm Picus Security has published an analysis detailing the T1018 Remote Service Discovery technique, a common method employed by advanced threat actors to map enterprise networks. This technique is crucial for attackers seeking to identify and exploit remote services for lateral movement within a compromised environment.
The MITRE ATT&CK framework classifies T1018 as a discovery technique. Attackers frequently leverage native operating system commands, such as Windows' net utility, to enumerate network resources and identify potential targets for further exploitation. This method allows them to gain a better understanding of the victim's infrastructure before proceeding with more complex attacks.
The report highlights the use of net commands by malware loaders like QAKBOT and IcedID for environmental information gathering after initial access. Additionally, it discusses the use of penetration testing tools, such as PowerSploit's PowerView module, by threat actors like Ryuk ransomware operators for discovering remote systems. Commands utilizing the Address Resolution Protocol (ARP), like arp -a, are also mentioned as part of these reconnaissance efforts.
Picus Security's work aims to shed light on this often-overlooked phase of cyberattacks. By understanding how attackers use these discovery methods, organizations can better implement defenses to detect and mitigate such activities. The analysis underscores the importance of proactive threat intelligence and robust security measures.
The company provides insights into how organizations can identify and defend against these attack vectors, emphasizing continuous threat assessment and readiness in the face of evolving cyber threats.
