Detects instances where 'node.exe' is copying browser history SQLite databases (Chrome, Edge, Brave) to temporary directories. This activity is indicative of data staging or collection, specifically linked to the 'protocal.cjs' backdoor from the 'easy-day-js' supply chain attack.
This rule detects network connections where the remote URL contains keywords commonly associated with financial transactions or sensitive financial information, such as 'neft', 'rtgs', 'imps', 'gst', 'pan', and 'ifsc'. This could indicate data exfiltration, unauthorized access to financial systems, or other malicious activities targeting financial data.
Detects a high number of office, PDF, text, and archive files created in Downloads or AppData Roaming by one process within fifteen minutes. This behavior is indicative of data staging prior to exfiltration.
Detects suspicious process executions where 'ctfmon.exe' or 'cloudfiles.exe' are initiated by a non-SYSTEM user but contain 'SYSTEM' in their command line. This could indicate an attempt to impersonate or escalate privileges, potentially by manipulating process arguments or environment variables to execute code as SYSTEM.
This rule detects suspicious execution of VBScript or VBE files via wscript.exe or cscript.exe where the command line contains keywords commonly associated with financial documents or urgent requests. A high count of such executions within an hour from a single device is flagged to identify potential phishing attempts or malware delivery.
Detects suspicious execution of VBScript (.vbs, .vbe) files via wscript.exe or cscript.exe where the command line contains keywords commonly associated with financial documents or urgent notifications. This rule specifically looks for multiple occurrences (3 or more) within an hour, indicating potential malicious activity like phishing or malware delivery.
Detects suspicious process executions where 'ctfmon.exe' or 'cloudfiles.exe' are initiated by a non-SYSTEM user but contain 'SYSTEM' in their command line. This could indicate an attempt to impersonate or escalate privileges, especially when combined with a successful logon event for the same user.
This rule detects the execution of specific Python scripts associated with the 'FortiBleed' campaign. These scripts include 'spray_da.py' (domain admin password spray), 'smb_test.py' (SMB validation/lateral movement), 'spider.py' (Active Directory crawler), and 'ad_full_audit.py' (Active Directory full audit). Detection is based on the Python executable (python.exe, python3, etc.) running with these script names in the command line or as the executed file.
This rule detects network connections using the GRE (Generic Routing Encapsulation) protocol to external IP addresses. GRE is often used for tunneling and can be leveraged by adversaries for command and control or data exfiltration, especially when communicating outside of internal networks.
This rule detects the launch of a process where its command line contains references to 'RawWNPF' or '\device\rawwnpf'. This pattern is often associated with malicious activity, specifically related to the 'Fishmonger's Arsenal' campaign and the 'SprySocks' malware, which utilize RawWNPF for inter-process communication or other low-level operations. The rule focuses on capturing the principal and target context for further correlation and investigation.
