Released July 14, 2019

  • New security alert: Suspected NTLM authentication tampering (external ID 2039)
    Azure ATP’s new Suspected NTLM authentication tampering security alert is now in public preview.
    In this detection, an Azure ATP security alert is triggered when use of "man-in-the-middle" attack is suspected of successfully bypassing NTLM Message Integrity Check (MIC), a security vulnerability detailed in Microsoft CVE-2019-040. These types of attacks attempt to downgrade NTLM security features and successfully authenticate, with the ultimate goal of making successful lateral movements.

  • Feature enhancement: Enriched device operating system identification
    Until now, Azure ATP provided entity device operating system information based on the available attribute in Active Directory. Previously, if operating system information was unavailable in Active Directory, the information was also unavailable on Azure ATP entity pages. Starting from this version, Azure ATP now provides this information for devices where Active Directory doesn't have the information, or are not registered in Active Directory, by using enriched device operating system identification methods.

    The addition of enriched device operating system identification data helps identify unregistered and non-Windows devices, while simultaneously aiding in your investigation process. For learn more about Network Name Resolution in Azure ATP, see Understanding Network Name Resolution (NNR).

    The step-by-step lab is designed to ensure you spend minimal time building, and more time learning about your threat landscape and available Azure ATP alerts and protection. We're excited to hear your feedback.

  • This version also includes improvements and bug fixes for internal sensor infrastructure.

Azure ATP release 2.67

Released February 24, 2019

  • New security alert: Security principal reconnaissance (LDAP) – (preview)

    Azure ATP’s Security principal reconnaissance (LDAP) - preview security alert is now in public preview.
    In this detection, an Azure ATP security alert is triggered when security principal reconnaissance is used by attackers to gain critical information about the domain environment. This information helps attackers map the domain structure, as well as identify privileged accounts for use in later steps in their attack kill chain.

    Lightweight Directory Access Protocol (LDAP) is one the most popular methods used for both legitimate and malicious purposes to query Active Directory. LDAP focused security principal reconnaissance is commonly used as the first phase of a Kerberoasting attack. Kerberoasting attacks are used to get a target list of Security Principal Names (SPNs), which attackers then attempt to get Ticket Granting Server (TGS) tickets for.

  • Feature enhancement: Account enumeration reconnaissance (NTLM) alert
    Improved Account enumeration reconnaissance (NTLM) alert using additional analysis, and improved detection logic to reduce B-TP and FP alert results.

  • Feature enhancement: Network mapping reconnaissance (DNS) alert

    Azure ATP’s Suspected NTLM relay attack (Exchange account) - preview security alert is now in public preview.
    In this detection, an Azure ATP security alert is triggered when use of Exchange account credentials from a suspicious source is identified. These types of attacks attempt to leverage NTLM relay techniques to gain domain controller exchange privileges and are known as ExchangePriv. Learn more about the ExchangePriv technique from the ADV190007 advisory first published January 31, 2019, and the Azure ATP alert response.

    • All remote execution activities, such as service creation, WMI execution, and the new PowerShell execution, were added to the profile timeline of the destination machine. The destination machine is the domain controller the command was executed on.
    • PowerShell execution was added to the list of remote code execution activities listed in the entity profile alert timeline.
    • See Remote code execution attempt to learn more.
  • Windows Server 2019 LSASS issue and Azure ATP
    In response to customer feedback regarding Azure ATP usage with domain controllers running Windows Server 2019, this update includes additional logic to avoid triggering the reported behavior on Windows Server 2019 machines.
