This kind of pattern, while possibly benign, is also typical of attackers trying to hide from case-sensitive or hash-based rule matching when performing administrative tasks on a compromised host. This kind of configuration, while possibly benign, is also typical of attacker activity when trying to move from unprivileged standard user to privileged for example administrator access on a compromised host.

Attackers are known to abuse functionality of legitimate administrator tools to perform malicious actions, for example using a tool such as certutil. Specifically this key has been updated to allow logon credentials to be stored in clear text in LSA memory.

Once enabled an attacker can dump clear text passwords from LSA memory with credential harvesting tools such as Mimikatz. This has previously been associated with attackers attempting to construct executables on-the-fly through a sequence of commands, and attempting to evade intrusion detection systems by ensuring that no individual command would trigger an alert.

This could be legitimate activity, or an indication of a compromised host. Attackers use increasingly complex obfuscation techniques to evade detections that run against the underlying data. Review the command line associated in this alert and escalate this alert to your security team. Activity group GOLD has been known to make use of such keygens to covertly gain back door access to hosts that they compromise.

While 'systeminfo. Analysis of host data shows installation of Telegram, a free cloud-based instant messaging service that exists both for mobile and desktop system. Attackers are known to abuse this service to transfer malicious binaries to any other computer, phone, or tablet. Microsoft security analysis has determined that this is a common activity undertaken by attackers after having compromised a host.

When a victim browses to the HTA file and chooses to run it, the PowerShell commands and scripts that it contains are executed. This could be an indication of a compromised host. This activity group has been known to use this password to execute Pirpi malware on a victim host. Encode command. This encodes the scripts into unreadable text, making it more difficult for users to examine the code. Microsoft threat research shows that attackers often use encoded VBscript files as part of their attack to evade detection systems.

This activity group has been known to use this technique to download additional malware to a compromised host after an attachment in a phishing doc has been opened. Named pipes are known to be a channel used by attackers to task and communicate with a malicious implant.

Such traffic, while possibly benign, is typically used by an attacker to communicate with malicious servers for downloading of tools, command-and-control and exfiltration of data. Typical related attacker activity includes copying remote administration tools to a compromised host and exfiltrating user data from it. Analysis of host data detected a new firewall rule has been added via netsh. Attackers use myriad ways like brute force, spear phishing etc.

Once initial compromise is achieved they often take steps to lower the security settings of a system. Cacls—short for change access control list is Microsoft Windows native command-line utility often used for modifying the security permission on folders and files. A lot of time the binary is used by the attackers to lower the security settings of a system.

This is done by giving Everyone full access to some of the system binaries like ftp. This switch is used to specify an FTP script file for the client to run. Malware or malicious processes are known to use this FTP switch -s:filename to point to a script file which is configured to connect to a remote FTP server and download additional malicious binaries. Attackers are known to abuse functionality of legitimate Windows system tools to perform malicious actions, for example using pcalua.

The stopping of either of these services can be indication of a malicious behavior. Attackers sometimes use this approach of progressively building up a script in order to evade IDS systems. This could be legitimate activity, or an indication that one of your machines has been compromised. This executable could either be legitimate activity, or an indication of a compromised host.

The memory of the process specified contains behaviors commonly used by fileless attacks. Specific behaviors include: 1 Shellcode, which is a small piece of code typically used as the payload in the exploitation of a software vulnerability. See NetworkConnections below for details. See Capabilities below for referenced OS capabilities. This is a common pattern for process injection attacks. The memory of the process specified below contains evidence of a fileless attack technique. Fileless attacks are used by attackers to execute code while evading detection by security software.

The memory of the process specified contains a fileless attack toolkit: [toolkit name]. Fileless attack toolkits use techniques that minimize or eliminate traces of malware on disk, and greatly reduce the chances of detection by disk-based malware scanning solutions.

Specific behaviors include: 1 Well-known toolkits and crypto mining software. A common technique utilized in the distribution of malicious software is to package it within otherwise benign tools such as the one seen in this alert. Upon using these tools, the malware can be silently installed in the background. A firewall rule was created using techniques that match a known actor, ZINC.

This behavior was seen [x] times today on the following machines: [Machine names]. This activity is considered malicious. This kind of activity could be legitimate, but can also be an indication of compromise. Analysis of host data has detected use of native windows tool e.

Attackers often use these techniques to extract credentials that they then further use for lateral movement and privilege escalation. AppLocker can be configured to implement a policy that limits what executables are allowed to run on a Windows system. The command-line pattern similar to that identified in this alert has been previously associated with attacker attempts to circumvent AppLocker policy by using trusted executables allowed by AppLocker policy to execute untrusted code.

PsExec can be used for running processes remotely. This technique might be used for malicious purposes. Analysis of host data indicates suspicious activity traditionally associated with lock-screen and encryption ransomware.

Lock screen ransomware displays a full-screen message preventing interactive use of the host and access to its files. Encryption ransomware prevents access by encrypting data files. In both cases a ransom message is typically displayed, requesting payment in order to restore file access. Several sign in attempts were detected from the same source. Some successfully authenticated to the host. This resembles a burst attack, in which an attacker performs numerous authentication attempts to find valid account credentials.

Analysis of host data has detected the tscon. Analysis of host data has detected the installation of tscon. Analysis of host data detected commandline parameters consistent with a Kerberos Golden Ticket attack.

This is potentially a rogue account created by an attacker, so named in order to avoid being noticed by a human administrator. While individual commands may appear benign the alert is scored based on an aggregation of these commands. This could either be legitimate activity, or an indication of a compromised host. Although none of them succeeded, some of them used accounts were recognized by the host. This resembles a dictionary attack, in which an attacker performs numerous authentication attempts using a dictionary of predefined account names and passwords in order to find valid credentials to access the host.

This indicates that some of your host account names might exist in a well-known account name dictionary. Indicates that a code segment has been allocated by using non-standard methods, such as reflective injection and process hollowing.

The alert provides additional characteristics of the code segment that have been processed to provide context for the capabilities and behaviors of the reported code segment. Analysis of host data indicates an execution of a process with a suspicious double extension.

This extension may trick users into thinking files are safe to be opened and might indicate the presence of malware on the system. Attackers are known to abuse functionality of legitimate administrator tools to perform malicious actions, for example using certutil. Suspicious failure of a custom script extension was detected in your virtual machine by analyzing the Azure Resource Manager operations in your subscription. Such failures may be associated with malicious scripts run by this extension.

This script could either be legitimate activity, or an indication of a compromised host. This process could be legitimate activity, or an indication that one of your machines has been compromised. This activity is uncommon with this account. Malware often uses this process name to masquerade its malicious activity. Analysis of host data has detected a shadow copy deletion activity on the resource. Some malware and specifically Ransomware, targets VSC to sabotage backup strategies. Known suspect Hex value includes, but not limited to cc While this process could be benign attackers are known to sometimes hide in plain sight by naming their malicious tools to resemble legitimate process names.

An unusual config reset was detected in your virtual machine by analyzing the Azure Resource Manager operations in your subscription. While this action may be legitimate, attackers can try utilizing VM Access extension to reset the configuration in your virtual machine and compromise it.

Unusual execution of a custom script extension was detected in your virtual machine by analyzing the Azure Resource Manager operations in your subscription. An unusual user password reset was detected in your virtual machine by analyzing the Azure Resource Manager operations in your subscription.

While this action may be legitimate, attackers can try utilizing the VM Access extension to reset the credentials of a local user in your virtual machine and compromise it.

An unusual user SSH key reset was detected in your virtual machine by analyzing the Azure Resource Manager operations in your subscription. While this action may be legitimate, attackers can try utilizing VM Access extension to reset SSH key of a user account in your virtual machine and compromise it. The following script contains HTTP object allocation command. This action can be used to download malicious files.

Analysis of host data has detected an attempt to persist an executable in the Windows registry. Malware often uses such a technique to survive a boot. Analysis of host data indicates that the command history log file has been cleared.

Attackers may do this to cover their traces. Htaccess is a powerful configuration file that allows you to make multiple changes to a web server running the Apache Web software including basic redirect functionality, or for more advanced functions such as basic password protection. Attackers will often modify htaccess files on machines they have compromised to gain persistence.

In some recent attacks, attackers have been observed stopping this service, to download malicious files and granting execution privileges for their attack. Attempt to stop apt-daily-upgrade. As rm -rf will recursively delete files, it is normally used on discrete folders. In this case, it is being used in a location that could remove a lot of data.

Fairware ransomware is known to execute rm -rf commands in this folder. Machine logs indicate execution of a Docker container that run an image associated with a digital currency mining. This behavior was seen over [x] times today on the following machines: [Machine names]. It is extremely rare that any legitimate process needs to execute in that mode, so this may indicate that an attacker has added a malicious process to every run-level to guarantee persistence.

Host data analysis has detected that a startup script for single-user mode has been installed. Because it's rare that any legitimate process would be required to run in that mode, this might indicate that an attacker has added a malicious process to every run-level to guarantee persistence. This behavior was seen 10 times today on the following machines: [Machine name]. The Linux Audit system provides a way to track security-relevant information on the system.

It records as much information about the events that are happening on your system as possible. Disabling auditd logging could hamper discovering violations of security policies used on the system. Machine logs indicate a build operation of a container image on a Kubernetes node. While this behavior might be legitimate, attackers might build their malicious images locally to avoid detection. Attackers may use this technique in privilege escalation attempts.
