Monitoring this anomaly helps identify potential threats and safeguard browser-stored data.
Suspicious Process DNS Query Known Abuse Web Services: endpointEndpointrisk_score:642024-11-28version:7
The following analytic detects a suspicious process making DNS queries to known, abused text-paste web services, VoIP, instant messaging, and digital distribution platforms. It leverages Sysmon EventID 22 logs to identify queries from processes like cmd.exe, powershell.exe, and others. This activity is significant as it may indicate an attempt to download malicious files, a common initial access technique. If confirmed malicious, this could lead to unauthorized code execution, data exfiltration, or further compromise of the target host.
Windows Query Registry UnInstall Program List: endpointEndpointrisk_score:252024-11-28version:4
The following analytic detects an access request on the uninstall registry key. It leverages Windows Security Event logs, specifically event code 4663. This activity is significant because adversaries or malware can exploit this key to gather information about installed applications, aiding in further attacks. If confirmed malicious, this behavior could allow attackers to map out installed software, potentially identifying vulnerabilities or software to exploit, leading to further system compromise.
Windows Access Token Manipulation SeDebugPrivilege: endpointEndpointrisk_score:362024-11-28version:5
The following analytic detects a process enabling the "SeDebugPrivilege" privilege token. It leverages Windows Security Event Logs with EventCode 4703, filtering out common legitimate processes. This activity is significant because SeDebugPrivilege allows a process to inspect and modify the memory of other processes, potentially leading to credential dumping or code injection. If confirmed malicious, an attacker could gain extensive control over system processes, enabling them to escalate privileges, persist in the environment, or access sensitive information.
Windows Gather Victim Network Info Through Ip Check Web Services: endpointEndpointrisk_score:252024-11-28version:7
The following analytic detects processes attempting to connect to known IP check web services. This behavior is identified using Sysmon EventCode 22 logs, specifically monitoring DNS queries to services like "wtfismyip.com" and "ipinfo.io". This activity is significant as it is commonly used by malware, such as Trickbot, for reconnaissance to determine the infected machine's IP address. If confirmed malicious, this could allow attackers to gather network information, aiding in further attacks or lateral movement within the network.
Windows Credential Access From Browser Password Store: endpointEndpointrisk_score:252024-11-28version:5
The following analytic identifies a possible non-common browser process accessing its browser user data profile. This tactic/technique has been observed in various Trojan Stealers, such as SnakeKeylogger, which attempt to gather sensitive browser information and credentials as part of their exfiltration strategy. Detecting this anomaly can serve as a valuable pivot for identifying processes that access lists of browser user data profiles unexpectedly. This detection uses a lookup file `browser_app_list` that maintains a list of well known browser applications and the browser paths that are allowed to access the browser user data profiles.
Suspicious Process File Path: endpointEndpointrisk_score:352024-11-28version:5
The following analytic identifies processes running from file paths not typically associated with legitimate software. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on specific process paths within the Endpoint data model. This activity is significant because adversaries often use unconventional file paths to execute malicious code without requiring administrative privileges. If confirmed malicious, this behavior could indicate an attempt to bypass security controls, leading to unauthorized software execution, potential system compromise, and further malicious activities within the environment.
Detect Outlook exe writing a zip file: networkEndpointrisk_score:252024-11-28version:8
The following analytic identifies the execution of `outlook.exe` writing a `.zip` file to the disk. It leverages data from the Endpoint data model, specifically monitoring process and filesystem activities. This behavior is significant as it may indicate the use of Outlook to deliver malicious payloads or exfiltrate data via compressed files. If confirmed malicious, this activity could lead to unauthorized data access, data exfiltration, or the delivery of malware, potentially compromising the security of the affected system and network.
Executables Or Script Creation In Suspicious Path: endpointEndpointrisk_score:202024-11-28version:5
The following analytic identifies the creation of executables or scripts in suspicious file paths on Windows systems. It leverages the Endpoint.Filesystem data model to detect files with specific extensions (e.g., .exe, .dll, .ps1) created in uncommon directories (e.g., \windows\fonts\, \users\public\). This activity is significant as adversaries often use these paths to evade detection and maintain persistence. If confirmed malicious, this behavior could allow attackers to execute unauthorized code, escalate privileges, or persist within the environment, posing a significant security threat.
Windows Credentials Access via VaultCli Module: endpointEndpointrisk_score:642024-11-29version:1
The following analytic detects potentially abnormal interactions with VaultCLI.dll, particularly those initiated by processes located in publicly writable Windows folder paths. The VaultCLI.dll module allows processes to extract credentials from the Windows Credential Vault. It was seen being abused by information stealers such as Meduza. The analytic monitors suspicious API calls, unauthorized credential access patterns, and anomalous process behaviors indicative of malicious activity. By leveraging a combination of signature-based detection and behavioral analysis, it effectively flags attempts to misuse the vault for credential theft, enabling swift response to protect sensitive user data and ensure system security.
Ping Sleep Batch Command: endpointEndpointrisk_score:362024-11-28version:4
The following analytic identifies the execution of ping sleep batch commands. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process and parent process command-line details. This activity is significant as it indicates an attempt to delay malicious code execution, potentially evading detection or sandbox analysis. If confirmed malicious, this technique allows attackers to bypass security measures, making it harder to detect and analyze their activities, thereby increasing the risk of prolonged unauthorized access and potential data exfiltration.
