From MITRE ATT&CK 19.2

Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network. Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system.

An adversary may need to determine if the remote system is in a vulnerable state, which may be done through Network Service Discovery or other Discovery methods looking for common, vulnerable software that may be deployed in the network, the lack of certain patches that may indicate vulnerabilities, or security software that may be used to detect or contain remote exploitation. Servers are likely a high value target for lateral movement exploitation, but endpoint systems may also be at risk if they provide an advantage or access to additional resources.

There are several well-known vulnerabilities that exist in common services such as SMB and RDP as well as applications that may be used within internal networks such as MySQL and web server services. Additionally, there have been a number of vulnerabilities in VMware vCenter installations, which may enable threat actors to move laterally from the compromised vCenter server to virtual machines or even to ESXi hypervisors.

Depending on the permissions level of the vulnerable remote service an adversary may achieve Exploitation for Privilege Escalation as a result of lateral movement exploitation as well.

How MITRE says to detect it DET0118

Exploitation of Remote Services – multi-platform lateral movement detection

Windows Analytic 0327

Correlates inbound network access to remote service ports (e.g., SMB/RPC 445/135, RDP 3389, WinRM 5985/5986) with near-time instability in the target service (crash, abnormal restart), suspicious child process creation under the service, and post-access lateral-movement behaviors. The chain indicates likely exploitation rather than normal administration.

  • WinEventLog:System EventCode=1000
  • WinEventLog:Sysmon EventCode=1
  • WinEventLog:Sysmon EventCode=3, 22
  • WinEventLog:Sysmon EventCode=7
  • WinEventLog:Sysmon EventCode=10
  • WinEventLog:Sysmon EventCode=11
  • NSM:Flow Inbound connections to 445, 3389, 5985-5986 with high error/connection-reset rate, followed by new outbound sessions from the same host to internal assets within short interval.

Linux Analytic 0328

Links inbound network access to SSHD/SMB/NFS/Databases or custom daemons with subsequent daemon crash/restart, core dump, or spawning of shells/reverse shells from the service context, indicating remote exploitation.

  • linux:syslog kernel|systemd messages indicating 'segmentation fault'|'core dumped'|'service terminated unexpectedly' for sshd, smbd, vsftpd, mysqld, httpd, etc.
  • auditd:SYSCALL execve of /bin/sh,/bin/bash,/usr/bin/curl,/usr/bin/python by service accounts (e.g., apache, mysql, nobody) immediately after inbound network activity.
  • NSM:Flow Inbound connections to monitored service ports from external or unusual internal sources; rapid follow-on lateral connections from the same host.

ESXi Analytic 0329

Detects exploitation targeting ESXi/vCenter by correlating attempts to reach known exploitable endpoints (OpenSLP 427, CIM 5989, Hostd/Vpxa HTTPS 443, ESXi SOAP) with vmkernel/hostd crashes, unexpected hostd/vpxa restarts, or new reverse/outbound connections from ESXi host/vCenter to internal assets.

  • esxi:hostd Keywords: 'Backtrace','Signal 11','PANIC','hostd restarted','assert' or 'Service terminated unexpectedly' in /var/log/hostd.log, /var/log/vmkernel.log, /var/log/syslog.log.
  • NSM:Flow Inbound to tcp/427 (OpenSLP), tcp/443 (vSphere APIs), tcp/902, tcp/5989 followed by new unexpected outbound sessions from the ESXi/vCenter host.

macOS Analytic 0330

Ties inbound access to exposed services (ARD/VNC 5900, SSH 22, ScreenSharing, web services) with process crashes in unified logs and abnormal child processes spawned under those services (e.g., bash, curl) to indicate exploitation.

  • macos:unifiedlog process 'crashed'|'EXC_BAD_ACCESS' for sshd, screensharingd, httpd; launchd restarts of these daemons.
  • macos:osquery parent_name in ('sshd','httpd','screensharingd') spawning shells or scripting runtimes.
  • NSM:Flow Inbound to 22/5900/8080 and follow-on internal connections.
