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 instances where the ESET Remote Administrator Agent (ERAAgent.exe) modifies registry keys related to Windows network security settings, such as LSA policies, NullSession pipes/shares, or server/workstation auto-sharing. These settings can be manipulated to weaken Windows security posture, potentially facilitating lateral movement or credential access.
Detects behavior where the ERAAgent process writes a file to disk and executes that same file shortly after (within 5 minutes). This pattern is consistent with staged payload delivery, decompression, or assembly often observed in malicious activity, specifically referencing SLEEPWALKER malware patterns.
Detects Python processes (python.exe, pythonw.exe, py.exe) executing with high or system integrity levels and interacting with named pipes, a technique often used for inter-process communication, persistence, or process injection.
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.
This rule monitors process command lines for identifiers related to virtual machine communication interfaces such as 'VMCI', 'AF_VSOCK', 'svm_cid', or 'vm:2'. It specifically targets both the ESET Remote Administrator (ERA) Agent and any other processes utilizing these communication mechanisms, which can be indicators of inter-process communication across virtual machine boundaries or potential hypervisor-related activity.
Detects modifications to Windows LSA and LanmanServer registry keys (RestrictAnonymous, NullSessionPipes) in conjunction with ERAAgent.exe process execution, as well as ERAAgent creating named pipes accessible by anonymous logon, which may indicate configuration tampering to facilitate unauthorized access or credential collection.
Detects the loading of compression libraries (such as lzma.dll or 7z.dll) by ERAAgent.exe followed by suspicious process or thread activity (e.g., remote thread creation, memory allocation). This pattern is often associated with the staging and execution of malicious payloads in memory.
This rule detects suspicious file system activity (creation, modification, or renaming) performed by the ESET Remote Administrator (ERA) Agent process, excluding files within standard ESET installation and ProgramData directories. This behavior may indicate an adversary attempting to leverage the legitimate ERA agent to perform unauthorized file operations or masquerading as the agent.
Detects a suspicious pattern associated with the SLEEPWALKER technique, involving multiple memory write operations followed by a memory protection change within an ERAAgent.exe process. This behavior suggests code injection or dynamic code loading within a process.
