This rule monitors for execution of files with specific SHA256 hashes known to be malicious, and network connections to a known malicious domain associated with Vultr storage. It aggregates file creation, process execution, and network connection events to detect potential threat activity.
This rule detects file creation or modification events occurring within the 'ProgramData\ZlibDate' directory. This specific path and the associated file extensions (.Dat and .zip) are frequently associated with data staging activities or unauthorized file management by malicious software attempting to persist or exfiltrate data under the guise of legitimate application data.
Detects network activity (DNS lookups, TLS SNI, and HTTP Host headers) associated with proxy infrastructure (iproyal.com and lightningproxies.net) known to be used by the HEAVYGRAM/CHOSEN BRICK threat actors to mask Telegram-based command and control traffic.
This rule detects potentially malicious activity by monitoring the execution of Python interpreters or specific suspicious executable names from within the C:\ProgramData directory. The detection logic focuses on processes launching from directories associated with configuration or data storage folders, often used by malware for staging or execution to avoid detection. It specifically flags Python execution involving certain suspicious file or argument strings, and the launch of named executables (e.g., RuntimeSSH.exe, smqdservice.exe) located in specific ProgramData subdirectories.
Detects instances where suspicious or potentially non-standard processes (e.g., winappx.exe, MsCache.exe) or Python scripts running from specific ProgramData subdirectories spawn cmd.exe with a /c command line argument. This pattern is often indicative of persistence mechanisms, lateral movement, or malicious script execution.
This rule detects unauthorized processes modifying the 'Secure Preferences' configuration file in Google Chrome or Microsoft Edge browser data directories. This activity often indicates an attempt by malicious software to hijack browser settings, such as forcing extensions or modifying security policies, which is a common precursor to credential theft or persistent malicious access.
This rule monitors endpoint network events, file operations, and process executions for known malicious indicators (domains and file hashes) associated with Kremlin activity. It detects connections to suspicious remote domains and the existence or execution of specific malicious file hashes.
Detects outbound network communication from common web browsers (chrome.exe, msedge.exe) to a specific malicious domain and path associated with suspected Kremlin-linked screenshot exfiltration activities.
Detects the creation of a scheduled task using schtasks.exe where the command line involves 'MicrosoftNodeRuntimeUpdater' and references 'node.exe' or '.js' files, specifically when initiated by script engines like node.exe, wscript.exe, or cscript.exe, while excluding known legitimate nodejs installation paths.
This rule detects attempts to exploit a path traversal vulnerability (CVE-2024-21762) in FortiOS SSL-VPN by monitoring for malformed GET requests targeting the /remote/fgt_lang endpoint. The rule also tracks successful exploitation by identifying HTTP 200 responses containing Linux password file patterns (root:x:0:0:), indicating potential remote file disclosure.
