Detects the addition of Microsoft Defender exclusions targeting the C:\Windows directory or SystemHealth\Update paths via PowerShell commands (Add-MpPreference/Set-MpPreference) or direct Registry modifications, which may indicate an attempt to evade security detection.
Detects command execution patterns on NetScaler appliances involving the extraction of system details (id, uname, hostname, nsrelease) and writing or echoing them into HTML files within NetScaler web directories, indicative of web shell installation or staging.
Detects Microsoft Entra ID sign-ins to specific third-party applications related to Updraft (TeamUpdraft, UpdraftCentral, UpdraftVault, UpdraftClone, UpdraftPlus) with anomalous characteristics such as multi-IP access, distinct countries, or failed-then-successful access attempts, indicating possible credential compromise or misuse.
Detects a single external source IP reading secrets and configmaps across multiple Kubernetes namespaces in bulk within a 1-hour window, which may indicate reconnaissance or credential theft.
Detects the setting of the TS_SERVE_ALLOW_ALL_INTERFACES environment variable or registry key combined with the execution of Tailscale serve or funnel commands on the same device within a 24-hour window, potentially indicating unauthorized exposure of local services.
Detects potential C2Agent parent-spoofing behavior characterized by short-lived scheduled tasks (created and deleted within a 10-minute window with names matching c2a_<n>) or process relaunches carrying specific -fork2 command-line markers.
Detects credential harvesting tooling and activity targeting PaperCut configuration and log files by identifying specific parser script executions, searches for PaperCut credential key patterns in process command lines, and the creation of related harvest artifacts.
Detects PowerShell using System.Net.WebClient DownloadFile or related commands to fetch tool dependencies (such as 7z, MSTSCLib, ffmpeg) from GitHub repositories associated with the 'websalat' naming convention, indicative of Salat Stealer or similar tool-loading activity.
Detects GitLab backend processes (such as puma, sidekiq, rails, ruby, bundle) spawning shells, scripting interpreters, or network tools with suspicious command-line parameters, potentially indicating post-exploitation activity or vulnerability exploitation.
Detects behavioral indicators of shell-driven cryptocurrency miner staging where a hidden .trace file or binary is created, executed, or referenced via command-line arguments within go2rtc or shared memory directories (/config/, /opt/go2rtc/, /etc/go2rtc/, /.config/go2rtc/, /dev/shm/), alongside indicators of mining pools or software such as XMRig.
