This rule detects potential exfiltration of sensitive files, specifically 'cert.pem' and 'private.key', via HTTP POST requests to the '/api/adbk/upload' endpoint. This pattern is characteristic of the RatHat malware attempting to exfiltrate device credentials to a Command and Control (C2) server.
This rule detects potentially malicious activity involving Linux backup software (Acronis) or attempts to modify file permissions (chmod setuid) to elevate privileges. It triggers when backup-related processes are executed by root or when commands indicative of privilege escalation or tampering occur in conjunction with backup-related paths or binaries.
This rule detects potentially suspicious reconnaissance activity against the Microsoft Graph API. It monitors for high volumes of diverse requests originating from a single account within a 30-minute window, specifically targeting multiple distinct object types such as users, groups, sites, and applications. Such behavior is indicative of an adversary attempting to enumerate or map the target cloud environment.
This rule detects Windows executable files that attempt to masquerade as legitimate software installers for Telegram, KeePass, or Pictory. These filenames and branding artifacts are associated with social engineering campaigns known to distribute malware families such as HEAVYGRAM and CRUDEEXCLUDE.
Detects the execution of the 'getevent' utility by a process running with the 'shell' user ID, specifically targeting Android input device nodes. This pattern is indicative of the RatHat malware's AdbTouchCapture module, which is used to monitor touch events to facilitate the unauthorized capture of PINs or pattern locks.
Detects the creation or modification of email inbox rules that perform suspicious actions such as deleting, moving to folders, or forwarding emails, specifically when those rules target keywords associated with sensitive financial or business communications like invoices, payments, or wire transfers. This behavior is indicative of an attacker attempting to hide evidence of a compromise or intercept sensitive business communications.
This rule detects successful user logins that utilize the 'deviceCode' authentication protocol in conjunction with suspicious network indicators, specifically traffic originating from residential proxies. This combination is highly indicative of potential phishing or unauthorized access attempts using stolen session tokens or bypassed MFA mechanisms.
This rule detects successful user logins utilizing the OAuth 2.0 device authorization grant flow where Multi-Factor Authentication (MFA) was bypassed, not applied, or not performed. The device code flow is a common vector for phishing attacks where users are tricked into entering a device code on a malicious site, potentially leading to unauthorized token acquisition.
Detects the installation of Windows services with image paths containing strings associated with known commodity malware or potentially unwanted software (Alinubx, CcProtect, nvfsflt64, NvFsFilter). This activity is often indicative of persistence mechanisms or driver-based malicious components being registered on the host.
Detects suspicious process injection, module loads, or thread creation events where a web browser process (chrome.exe or msedge.exe) is the target, excluding known legitimate browser-related processes or sub-components like the elevation service.
