Detects attempts to tamper with Microsoft Windows Defender configuration, specifically by modifying exclusion paths via PowerShell cmdlets (Add-MpPreference, Set-MpPreference), direct registry modifications, or forced Group Policy updates. It also monitors for the disabling of Tamper Protection via registry and the creation of scheduled tasks designed to apply Defender exclusions.
Detects network requests to unpkg.com or npmmirror for 'index.html' files directly under a package path. This behavior deviates from standard package management usage (which typically fetches tarballs or specific JavaScript modules) and is often associated with adversaries using npm packages as hosting infrastructure for phishing landing pages.
Detects a high volume of outbound emails (more than 20 within a one-hour window) from a single sender containing the subject line 'Payment Transaction Failed Reminder', which is a common pattern for phishing or social engineering campaigns.
Detects potential remote code execution (RCE) attempts targeting vulnerable Sub-Store instances (versions < 2.38.2). The detection identifies web browsers making network connections to local ports (38324) associated with Sub-Store, followed by the spawning of shell processes (cmd, powershell, bash, sh) by the Node.js process hosting the application.
Detects the loading of the somkernl.dll module by 360speedld.exe or SoftupNotify.exe, or the execution of these binaries. These files are associated with 360 Safe/360 Security software components, and this rule monitors for their specific activity patterns, which may be used to identify software presence or potential process hollowing/masquerading attempts involving these legitimate components.
Detects unauthenticated execution of sensitive Grafana MCP tools (tools/call, grafana_api_request) by identifying session IDs that lack a corresponding authenticated handshake event. This behavior is indicative of potential session spoofing or abuse of the MCP protocol where an attacker attempts to interact with privileged tools without performing a valid authentication handshake.
Detects incoming Grafana API requests directed at vulnerable mcp-grafana server instances identified by an outdated version (pre-1.1.0). This rule correlates host-level version discovery with application-layer logs containing suspicious 'grafana_api_request' method calls, which may indicate an attempt to exploit Server-Side Request Forgery (SSRF) vulnerabilities.
Detects sessions using shared Grafana service account tokens that perform both read-only and action-capable tool operations without confirmed prior authentication. This behavior is indicative of an unauthenticated or spoofed session leveraging a service account's excessive permissions, bypassing standard authentication flows.
Detects processes other than the official Telegram desktop client accessing sensitive local data files ('key_datas', 'settingss', 'usertag') within the Telegram application directory. This activity is often associated with credential theft or session hijacking.
Detects the execution of cmstp.exe with the /au parameter, which is commonly used to install malicious INF files, when initiated by LockAppHost.exe. This pattern is often indicative of an attempt to bypass application control or achieve privilege escalation by leveraging the legitimate Microsoft Connection Manager Profile Installer.
