2 rules 2 TTPsAdversaries may use the `netsh.exe` utility to enable inbound Remote Desktop Protocol (RDP) connections in the Windows Firewall, potentially allowing unauthorized remote access to compromised systems.
Mounting of Hidden or WebDav Remote Shares via Net Utility
2 rules 4 TTPsAdversaries may leverage the `net.exe` utility to mount WebDav or hidden remote shares, potentially indicating lateral movement, data exfiltration preparation, or initial access via discovery of accessible shares.
Lateral Movement via Startup Folder File Creation
2 rules 4 TTPsAdversaries may move laterally by dropping malicious scripts or executables into a remote system's startup folder via RDP or SMB, enabling execution upon reboot or user logon.
Lanman NullSessionPipe Registry Modification for Lateral Movement
2 rules 2 TTPsAdversaries may modify the NullSessionPipe registry key to enable anonymous access to named pipes, facilitating lateral movement and defense evasion by allowing unauthorized access to network resources.
Kubeletctl Execution Inside Container Detected
3 rules 3 TTPsThis rule detects the execution of kubeletctl inside a container, which can be used to enumerate the Kubelet API or other resources inside the container, potentially indicating lateral movement attempts within the pod.
Impossible Travel Detection in Azure AD
2 rules 1 TTPThis brief describes the detection of 'impossible travel' events in Azure AD, where a user appears to log in from geographically distant locations within an implausibly short time frame, potentially indicating account compromise.
Firewall Rule Manipulation via COM API
2 rules 1 TTPA tool enables threat actors to add, remove, or query Windows Firewall rules via the COM API (INetFwPolicy2), bypassing traditional command-line tools and potentially evading detection.
Remote Execution via File Shares
2 rules 1 TTPThis rule identifies potential lateral movement via network file shares by detecting the execution of a file that was created by the virtual system process.
Remote Execution of Windows Services via RPC
2 rules 2 TTPsDetection of remote execution of Windows services over RPC by correlating `services.exe` network connections and spawned child processes, potentially indicating lateral movement.
High Variance in RDP Session Duration Detected via Machine Learning
2 rules 2 TTPsA machine learning job has detected unusually high variance of RDP session duration, potentially indicating lateral movement and session persistence by threat actors.
