ATA suspicious activity guide . Successfully guessed accounts can be used in subsequent steps of the attack. Look at the computer in question and try to determine if there is a legitimate reason why it would start so many Kerberos authentication processes. These are processes that tried and failed to learn multiple accounts, because the user doesn't exist, (Client. Exceptions: This detection relies on finding multiple non- existing accounts and attempting authentication from a single computer. If a user makes a mistake while manually typing a username or a domain, the authentication attempt is seen as an attempt to log on to a non- existing account. Terminal servers that require many users to log in might legitimately have a large number of mistaken log in attempts.

Investigate the process responsible for generating these requests. The Security Account Manager Remote (SAM- R) protocol is one of the methods used to query the directory. Understand why the computer in question is performing Security Accounts Manager - Remote (MS- SAMR).

This is being performed in an abnormal way, likely querying sensitive entities. Exceptions: This detection relies on profiling the normal behavior of users who make SAM- R queries, and alerting you when an abnormal query is observed. Sensitive users who log in to computers that they do not own may trigger a SAM- R query that will be detected as abnormal, even if it is a part of the normal work process. This can commonly happen to members of the IT team. If this is flagged as suspicious but was the result of normal use, it is because the behavior was not formerly observed by ATA. In this case, it is recommended to have a longer learning period and better coverage of ATA in the domain, per Active Directory forest. Download and run the “SAMRi.

SAMRi. 10 was releasesd by the ATA team, which hardens your environment against SAM- R queries. Medium. Reconnaissance using DNSDescription. Investigation. Recommendation.

Severity. Your DNS server contains a map of all the computers, IP addresses and services in your network. This information is used by attackers to map your network structure and target interesting computers for later steps in their attack. Understand why the computer in question is performing a Full Transfer Zone (AXFR) query to get all the records in the DNS domain. Exceptions: This detection identifies non- DNS servers that issue DNS zone transer requests. There are several security scanner solutions that are known to issue these kinds of requests to DNS servers.

Also, verify ATA is able to communicate via port 5. ATA Gateways to the DNS servers to avoid false positive scenarios.

Limit Zone Transfer by carefully choosing which hosts can request it. For more details see Securing DNS and Checklist: Secure Your DNS Server. Medium. Reconnaissance using SMB Session Enumeration. Description. Investigation. Recommendation. Severity. Server Message Block (SMB) enumeration enables an attacker to get information about which IP addresses users in your network recently logged on from.

Once an attacker has this information, they can use it to target specific accounts and move around laterally in the network. Understand why the computer in question is performing SMB Session enumerations. Exceptions: This detection relies on the assumption that SMB session enumeration has no legitimate use in an enterprise network, but some security scanner solutions (such as Websense) issue such requests.

Use the net cease tool to harden your environment. Medium. Brute- force (LDAP, Kerberos, NTLM)Description. Investigation. Recommendation.

Severity. In a brute- force attack, an attacker tries many passwords, hoping to eventually guess correctly. The attacker systematically checks all possible passwords (or a large set of possible passwords) until the correct one is found.

After an attacker guesses the correct password, they can login to the network as if they were the user. Currently ATA supports horizontal (multiple accounts) brute- force using the Kerberos or NTLM protocol, and horizontal and vertical (single account, multiple password attempts) using LDAP simple bind. Understand why the computer in question might be failing to authenticate multiple user accounts (having roughly the same number of authentication attempts for multiple users) or why there was a large number of authentication failures for a single user.

Exceptions: This detection relies on profiling the normal behavior of accounts that authenticate to different resources, and alert is triggered when an abnormal pattern is observed. This pattern is not uncommon in scripts that authenticate automatically but might use outdated credentials (i. Attackers monitoring your traffic can catch hold of these credentials for malicious purposes. Any clear text password of a sensitive account will trigger the alert.

Find the perpetrating computer and find out why it’s using LDAP simple binds. Verify the configuration on the source computers and make sure not to use LDAP simple bind. Instead of using LDAP simple binds use LDAP SALS or LDAPS. Follow the Security Tiered Framework and restrict access across the tiers to prevent privilege escalation.

Low for service exposing; Medium for sensitive accounts. Honey Token account suspicious activities. Description. Investigation. Recommendation. Severity. Honey Token accounts are decoy accounts set up to trap, identify, and track malicious activity in the network that involves these accounts. These are accounts that are unused and dormant on your network, and if there is suddenly activity from a honey token account, it can indicate that a malicious user is attempting to use this account.

Understand why a honey token account be authenticating from this computer. Browse through the ATA profile pages of other sensitive (privileged) accounts in your environment to see if there are potentially suspicious activities. Medium. Unusual protocol implementation. Description. Investigation.

Recommendation. Severity. Attackers can use tools that implement SMB/Kerberos protocols in certain ways that enable them to achieve capabilities over your network. This is indicative of malicious techniques used for over- pass- the- hash or brute force attacks. Understand why the computer in question would use an authentication protocol or SMB in an unusual way. To determine whether this is a Wanna.

Cry attack, do this: 1. How To Write Amharic On Microsoft Word. Some pen testing applications are known to do this.

Capture network traffic and identify which process is generating traffic with the unusual protocol implementation. Medium. Malicious Data Protection Private Information Request. Description. Investigation. Recommendation. Severity. The Data Protection API (DPAPI) is used by several components of Windows to securely store passwords, encryption keys and other sensitive data. Domain controllers hold a backup master key that can be used to decrypt all secrets encrypted with DPAPI by domain- joined Windows machines.

Attackers can use the DPAPI domain backup master key to decrypt all secrets on all domain- joined machines (browser passwords, encrypted files, etc.). Understand why the computer made a request using this undocumented API call for the master key for DPAPI. Read more about DPAPI in Windows Data Protection.

High. Suspicion of identity theft based on abnormal behavior. Description. Investigation. Recommendation. Severity. After building a behavioral model (it takes at least 5. Behavior that does not match the model built for a specific user account could point to identity theft.

Understand why the user in question might be behaving differently. Exceptions: If ATA only has partial coverage (not all domain controllers are routed to an ATA Gateway), then only partial activity is learned for a specific user. If suddenly, after more than 3 weeks, ATA starts covering all your traffic, full activity of the user could cause the alert to be triggered. Make sure ATA is deployed on all your domain controllers.
