Identify suspicious activity processes from startup records in the DOS Insight Agent collection invoked by Windows endpoints.
Extract an attacker from an archive with a 7zip detection password
Table of Contents
Description
This indicates that the compression utility “7za the.exe” is enabled, which extracts the library’s encrypted content using a password. This technique is still used by attackers to help deliver encrypted binaries to an endpoint so you can run them before execution. If
Recommendation
To determine, they, that the actual initiated procedure represents expected or otherwise carcinogenic behavior. If necessary, copy Go to litter from a known good source, save it, and change the user’s password.
MITER ATT&CK methods
- Transfer Tool – Records T1105
Description
This detection indicates the use of the main compression utility 7za.For exe to extract an archive containing content encrypted with a different password. This method is only used maliciously Members to deliver protected binary files to the endpoint before execution.
Recommendation
Determine if a running process is caused by some safe other behavior. If necessary, rebuild the host from a known-good host, and typically change the user’s password from the source.

Add technical attack – domain or enterprise network administrator
Description
This discovery identifies the “net.exe” or “net1.exe” command whose arguments match what you passed to add the owner to the “Administrators or Corporations” Domain Admins group. This method is used easily by attackers and attackers to elevate the privileges of your target account.
Recommendation
Check the notification in the request. If necessary, rebuild host c from a known-good source, and also ask the user to change the password. Also check for options with active root users in the directory delete and remove.Visible unknowns or participants.
MITER ATT&CK methods

The
ce directive identifies “net.exe” or “net1.exe” with arguments to pass this element to add a user you make “Domain Admins”. or “Domain Admins”. This method is used by security principals and malware testers to enforce target site privileges.
Recommendation
Check the related warning. When it is imperative that the host be recreated from a good source and that people change their password. Also check the active privileged groups in the users directory and remove unidentified or unexpected members.MITER

Attack Technique: Bypassing AppLocker Using SCT Code Execution
Description
This detector detects that Identifies the “advpack.Est dll” used to populate the specially crafted scenenaria “.inf”, which contains the execution match for the remote transfer “.sct”. This method is used primarily by attackers to bypass Microsoft AppLocker. If
yes
Recommendation
Determine whether a running process is behaving predictably or harmlessly. If this rebuild correctly, host from a trusted source, then change the password.ATT&CK
Signed binary proxy mitter methods – T1218
Description
This detection identifies the use of “advpack.dll”, which loads a specially crafted “.inf” script containing instructions to run a single “.sct” file. This method is used by attackers to bypass Microsoft AppLocker.
Recommendation
Determine whether you want a running process or harmless other behavior. If necessary, rebuild the host from a known good source and change the user’s password as a rule.

Attack Technique: Direct Obfuscation Reverse Arrayfor identified powershell detection
description
is the string passed to “[array]::reverse” and “PowerShell.exe” in various obfuscated forms. This can be described as a technique used by attackers to obfuscate the submitted script, allowing them to bypass the PowerShell .exe, some of which bypass types in simple detection blocks, or which may activate the content of the script being used.
Recommendation
Check the related warning. If necessary, re-create the host from a known trusted source and ask the master user to change their password.
ATT&CK methods
Description
This identifies the detection of the “[Array]::Reverse” semantic string that will be passed to “PowerShell.exe” in masked forms range by. This is a technique used by attackers to hide the passed-in PowerShell.exe package, bypassing some simple locks or simple detections that might be triggered.Depending on the nature of the content of the script.
Recommendation
Check the mindfulness question. If necessary, now rebuild the host on a known-good basis and ask users to change their personal password. ATT&CK methods

Attack Technique Assigning a Mailbox to Another User Using PowerShell
Description
This discovery identifies the Get-ManagementRoleAssignment cmdlet that was passed through the leader to PowerShell.exe. This method is used by attackers to effectively gain access to privileged mailboxes to steal users.
Recommendation
Check the related warning. If necessary, create a host from a known source of good quality and improve your password.MITER

Attack technique – executing Du binaries from Windows\Temp\Sys
Description
This detection identifies the binary files in the directory where “windows\temp\sys” is currently running. This directory is used by known attackers to store tools and malware that can be used against an insider attack. If
Recommendation
Determine whether the concept being thrown is expected or benign behavior. Rebuild the host if necessaryt from a good, famous and lender change your user password.
Description
This detection identifies binaries from the running windows\temp\sys directory. This list of addresses is used by attackers. They may contain tools and malware that can be used to prevent compromise. If they are,
recommendation
determine the meaning of the initiated process, or other civilized behavior expected. If necessary, the host can receive the beacon from a trusted source, and users can change their passwords.
Attack technique – blacklisted user accounts
Description
This identifies command line activity for blacklisted users observed by Rapid7 in previous and/or modern campaigns. Attackers may use an account account address and/or multiple passwords. About
