This rule detects activity associated with the exploitation of PaperCut vulnerabilities. It looks for connections to known malicious IP addresses, the presence of specific credential harvesting tools, reconnaissance commands (whoami, tasklist) executed by the PaperCut application (pc-app.exe), suspicious PowerShell downloads of AnyDesk, and unauthorized access to PaperCut configuration files or log files containing known exploit strings.

Detects attempts to access or create copies of the Active Directory 'ntds.dit' database or the Windows Security Account Manager (SAM) registry hive using unauthorized processes. Attackers often target these files to extract credential hashes from Domain Controllers or local systems.

This rule detects potential credential and keystroke theft by identifying the installation of a Windows hook (SetWindowsHookEx) followed within 30 minutes by file access to sensitive browser credential stores (Login Data, key4.db, etc.) by the same process on a single device.
Detects instances where the ESET Remote Administrator Agent (ERAAgent.exe) terminates shortly after loading the Data Protection API service (dpapisvc.dll). This pattern may indicate an attempt to interact with or disrupt DPAPI services, potentially to facilitate credential dumping or sensitive data access.

Detects Invoke-Mimikatz PowerShell script and alike. Mimikatz is a credential dumper capable of obtaining plaintext Windows account logins and passwords.
Detects anomalous access to specific registry keys under SYSTEM\CurrentControlSet\Control\Lsa that are associated with LSA secrets. The rule monitors for multiple registry operations (set, create, delete) performed by processes other than standard Windows system processes (lsass.exe, svchost.exe, winlogon.exe, services.exe), which is often indicative of credential dumping attempts.
Detects the execution of the hacktool Rubeus using specific command line flags
Detects ERAAgent.exe (ESET Remote Administrator Agent) interacting with suspicious named pipes (e.g., mojo, spoolss) and attempts to extract credentials from command line parameters, indicating potential credential dumping or lateral movement techniques using the agent process.
Detects the execution of psql.exe to query the Veeam Backup & Replication PostgreSQL database for stored credentials. This pattern is associated with credential theft techniques utilized during ransomware operations (e.g., Bumblebee, Akira) where sensitive configuration or credential data is retrieved and potentially later decrypted via DPAPI.
Detects ERAAgent.exe (ESET Remote Administrator Agent) interacting with suspicious named pipes (e.g., mojo, spoolss) and attempts to extract credentials from command line parameters, indicating potential credential dumping or lateral movement techniques using the agent process.

Correlates BTR_CLI arbitrary-write invocations (Action 3) targeting System32\drivers with a resulting file write of a known-malicious hash (e.g., mimidrv.sys) or an unsigned/non-Microsoft-signed binary — detecting the kernel write primitive being used to plant a malicious driver into a protected directory.

This rule detects potentially unauthorized access or memory dumping attempts against the Local Security Authority Subsystem Service (LSASS) process. It monitors for events where processes interact with LSASS or execute commands containing 'lsass.exe', 'MiniDump', or 'comsvcs.dll', while excluding known administrative and benign processes like Task Manager, Procdump, and Windows Error Reporting.
This rule detects hosts exhibiting behavior consistent with an active ransomware or destructive attack in progress, by correlating five distinct attack-chain stages within a rolling 24-hour window: environment/AD enumeration, network share discovery, lateral movement via RDP, credential dumping, and backup/recovery destruction.
