VMware VCenter

Overview

VMWare VCenter is a centralized management software. It provides a single point of control for managing virtual machines and ESXi hosts from a centralized interface.

The following Sekoia.io built-in rules match the intake VMware vCenter. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.

SEKOIA.IO x VMware vCenter on ATT&CK Navigator

Account Added To A Security Enabled Group

Detection in order to investigate who has added a specific Domain User in Domain Admins or Group Policy Creator Owners (Security event 4728)

  • Effort: master
Account Removed From A Security Enabled Group

Detection in order to investigate who has removed a specific Domain User in Domain Admins or Group Policy Creator Owners (Security event 4729)

  • Effort: master
Active Directory Data Export Using Csvde

Detects the use of Csvde, a command-line tool from Windows Server that can be used to export Active Directory data to CSV files. This export doesn't include password hashes, but can be used as a discovery tool to enumerate users, machines and group memberships.

  • Effort: elementary
AdFind Usage

Detects the usage of the AdFind tool. AdFind.exe is a free tool that extracts information from Active Directory. Wizard Spider (Bazar, TrickBot, Ryuk), FIN6 and MAZE operators have used AdFind.exe to collect information about Active Directory organizational units and trust objects

  • Effort: elementary
Adexplorer Usage

Detects the usage of Adexplorer, a legitimate tool from the Sysinternals suite that could be abused by attackers as it can saves snapshots of the Active Directory Database.

  • Effort: advanced
Certificate Authority Modification

Installation of new certificate(s) in the Certificate Authority can be used to trick user when spoofing website or to add trusted destinations.

  • Effort: master
Computer Account Deleted

Detects computer account deletion.

  • Effort: master
Cryptomining

Detection of domain names potentially related to cryptomining activities.

  • Effort: master
Domain Trust Created Or Removed

A trust was created or removed to a domain. An attacker could perform that in order to do lateral movement easily between domains or shutdown the ability of two domains to communicate.

  • Effort: advanced
Dynamic DNS Contacted

Detect communication with dynamic dns domain. This kind of domain is often used by attackers. This rule can trigger false positive in non-controlled environment because dynamic dns is not always malicious.

  • Effort: master
Exfiltration And Tunneling Tools Execution

Execution of well known tools for data exfiltration and tunneling

  • Effort: advanced
Exfiltration Domain

Detects traffic toward a domain flagged as a possible exfiltration vector.

  • Effort: master
Failed Logon Source From Public IP Addresses

A login from a public IP can indicate a misconfigured firewall or network boundary. The sekoia.tags are used to filter internal Ipv4 addresses (10.0.0.0/8 172.16.0.0/12 127.0.0.0/8 169.254.0.0/16 192.168.0.0/16).

  • Effort: master
Kernel Module Alteration

Kernel module installation can be used to configure system settings to automatically execute a program during system boot or logon to maintain persistence or gain higher-level privileges on compromised systems.

  • Effort: advanced
Network Scanning and Discovery

Tools and command lines used for network discovery from current system

  • Effort: advanced
Network Sniffing

List of common tools used for network packages sniffing

  • Effort: advanced
Network Sniffing Windows

Network sniffing refers to using the network interface on a system to monitor or capture information sent over a wired or wireless connection. An adversary may place a network interface into promiscuous mode to passively access data in transit over the network, or use span ports to capture a larger amount of data.

  • Effort: intermediate
Nimbo-C2 User Agent

Nimbo-C2 Uses an unusual User-Agent format in its implants.

  • Effort: intermediate
Password Change On Directory Service Restore Mode (DSRM) Account

The Directory Service Restore Mode (DSRM) account is a local administrator account on Domain Controllers. Attackers may change the password to gain persistence.

  • Effort: intermediate
PasswordDump SecurityXploded Tool

Detects the execution of the PasswordDump SecurityXploded Tool

  • Effort: elementary
Possible Replay Attack

This event can be a sign of Kerberos replay attack or, among other things, network device configuration or routing problems.

  • Effort: intermediate
Potential Azure AD Phishing Page (Adversary-in-the-Middle)

Detects an HTTP request to an URL typical of the Azure AD authentication flow, but towards a domain that is not one the legitimate Microsoft domains used for Azure AD authentication.

  • Effort: intermediate
Potential Bazar Loader User-Agents

Detects potential Bazar loader communications through the user-agent

  • Effort: elementary
Potential Lemon Duck User-Agent

Detects LemonDuck user agent. The format used two sets of alphabetical characters separated by dashes, for example "User-Agent: Lemon-Duck-[A-Z]-[A-Z]".

  • Effort: elementary
Potential LokiBot User-Agent

Detects potential LokiBot communications through the user-agent

  • Effort: intermediate
PsExec Process

Detects PsExec execution, command line which contains pstools or installation of the PsExec service. PsExec is a SysInternals which can be used to execute a program on another computer. The tool is as much used by attackers as by administrators.

  • Effort: advanced
RDP Session Discovery

Detects use of RDP session discovery via qwinsta or quser. Used by some threat actors to know if someone is working via RDP on a server.

  • Effort: advanced
Remote Access Tool Domain

Detects traffic toward a domain flagged as a Remote Administration Tool (RAT).

  • Effort: master
Remote Monitoring and Management Software - AnyDesk

Detect artifacts related to the installation or execution of the Remote Monitoring and Management tool AnyDesk.

  • Effort: master
Remote Monitoring and Management Software - Atera

Detect artifacts related to the installation or execution of the Remote Monitoring and Management tool Atera.

  • Effort: master
SEKOIA.IO Intelligence Feed

Detect threats based on indicators of compromise (IOCs) collected by SEKOIA's Threat and Detection Research team.

  • Effort: elementary
Sekoia.io EICAR Detection

Detects observables in Sekoia.io CTI tagged as EICAR, which are fake samples meant to test detection.

  • Effort: master
Suspicious Double Extension

Detects suspicious use of an .exe extension after a non-executable file extension like .pdf.exe, a set of spaces or underlines to cloak the executable file in spearphishing campaigns

  • Effort: advanced
System Info Discovery

System info discovery, attempt to detects basic command use to fingerprint a host.

  • Effort: master
TOR Usage Generic Rule

Detects TOR usage globally, whether the IP is a destination or source. TOR is short for The Onion Router, and it gets its name from how it works. TOR intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion. Each relay knows only enough to strip off the outermost layer of encryption, before passing what’s left on to the next relay in the list.

  • Effort: master
User Account Created

Detects user creation on windows servers, which shouldn't happen in an Active Directory environment. Apply this on your windows server logs and not on your DC logs. One default account defaultuser0 is excluded as only used during Windows set-up. This detection use Security Event ID 4720.

  • Effort: master
User Account Deleted

Detects local user deletion

  • Effort: master
