Node.js is a popular open-source JavaScript runtime that runs code outside browsers and is widely used for both frontend and backend development. Adversaries have been observed abusing Node.js to disguise malware as legitimate processes, evade security defenses, and maintain persistence within target systems. Because Node.js is commonly used, this rule may generate false positives in some environments. However, if such activity is unusual in your environment, it is highly suspicious and warrants immediate investigation.

Query: Multiple failed authentications followed by Fileless Storage
Matching passage: T1027.011 Fileless Storage. Tactics: stealth. Description: Adversaries may store data in "fileless" formats to conceal malicious activity from defenses. Fileless storage can be broadly defined as any format other than a file. Common examples of non-volatile fileless storage in Windows systems include the Windows Registry, event logs, or WMI repository.(Citation: Microsoft Fileless)(Citation: SecureList Fileless) Shared memory directories on Linux systems (`/dev/shm`, `/run/shm`, `/var/run`, and `/var/lock`) and volatile directories on Network Devices (`/tmp` and `/volatile`) may also be considered fileless storage, as files written to these directories are mapped directly to RAM and not stored on the disk.(Citation: Elastic Binary Executed from Shared Memory Directory)(Citation: Akami Frog4Shell 2024)(Citation: Aquasec Muhstik Malware 2024)(Citation: Bitsight 7777 Botnet)(Citation: CISCO Nexus 900 Config). Similar to fileless in-memory behaviors such as [Reflective Code Loading](https://attack.mitre.org/techniques/T1620) and [Process Injection](https://attack.mitre.org/techniques/T1055), fileless data storage may remain undetected by antivirus and other endpoint security tools that can only access specific file formats from disk storage. Leveraging fileless storage may also allow adversaries to bypass the protections offered by read-only file systems in Linux.(Citation: Sysdig Fileless Malware 23022) Adversaries may use fileless storage to conceal various types of stored data, including payloads/shellcode (potentially being used as part of [Persistence](https://attack.mitre.org/tactics/TA0003)) and collected data not yet exfiltrated from the victim (e.g., [Local Data Staging](https://attack.mitre.org/techniques/T1074/001)). Adversaries also often encrypt, encode, splice, or otherwise obfuscate this fileless data when stored. Some forms of fileless storage activity may indirectly create artifacts in the file system, but in central and otherwise difficult to inspect formats such as the WMI (e.g., `%SystemRoot%\System32\Wbem\R
Near-miss passage: T1027.005 Indicator Removal from Tools. Tactics: stealth. Description: Adversaries may remove indicators from tools if they believe their malicious tool was detected, quarantined, or otherwise curtailed. They can modify the tool by removing the indicator and using the updated version that is no longer detected by the target's defensive systems or subsequent targets that may use similar systems. A good example of this is when malware is detected with a file signature and quarantined by anti-virus software. An adversary who can determine that the malware was quarantined because of its file signature may modify the file to explicitly avoid that signature, and then re-use the malware.
Query: indicators of SSH Hijacking
Matching passage: T1563.001 SSH Hijacking. Tactics: lateral movement. Description: Adversaries may hijack a legitimate user's SSH session to move laterally within an environment. Secure Shell (SSH) is a standard means of remote access on Linux and macOS systems. It allows a user to connect to another system via an encrypted tunnel, commonly authenticating through a password, certificate or the use of an asymmetric encryption key pair. In order to move laterally from a compromised host, adversaries may take advantage of trust relationships established with other systems via public key authentication in active SSH sessions by hijacking an existing connection to another system. This may occur through compromising the SSH agent itself or by having access to the agent's socket. If an adversary is able to obtain root access, then hijacking SSH sessions is likely trivial.(Citation: Slideshare Abusing SSH)(Citation: SSHjack Blackhat)(Citation: Clockwork SSH Agent Hijacking)(Citation: Breach Post-mortem SSH Hijack) [SSH Hijacking](https://attack.mitre.org/techniques/T1563/001) differs from use of [SSH](https://attack.mitre.org/techniques/T1021/004) because it hijacks an existing SSH session rather than creating a new session using [Valid Accounts](https://attack.mitre.org/techniques/T1078).
Near-miss passage: T1563 Remote Service Session Hijacking. Tactics: lateral movement. Description: Adversaries may take control of preexisting sessions with remote services to move laterally in an environment. Users may use valid credentials to log into a service specifically designed to accept remote connections, such as telnet, SSH, and RDP. When a user logs into a service, a session will be established that will allow them to maintain a continuous interaction with that service. Adversaries may commandeer these sessions to carry out actions on remote systems. [Remote Service Session Hijacking](https://attack.mitre.org/techniques/T1563) differs from use of [Remote Services](https://attack.mitre.org/techniques/T1021) because it hijacks an existing session rather than creating a new session using [Valid Accounts](https://attack.mitre.org/techniques/T1078).(Citation: RDP Hijacking Medium)(Citation: Breach Post-mortem SSH Hijack)

Query: Multiple failed authentications followed by Transmitted Data Manipulation
Matching passage: T1565.002 Transmitted Data Manipulation. Tactics: impact. Description: Adversaries may alter data en route to storage or other systems in order to manipulate external outcomes or hide activity, thus threatening the integrity of the data.(Citation: FireEye APT38 Oct 2018)(Citation: DOJ Lazarus Sony 2018) By manipulating transmitted data, adversaries may attempt to affect a business process, organizational understanding, and decision making. Manipulation may be possible over a network connection or between system processes where there is an opportunity deploy a tool that will intercept and change information. The type of modification and the impact it will have depends on the target transmission mechanism as well as the goals and objectives of the adversary. For complex systems, an adversary would likely need special expertise and possibly access to specialized software related to the system that would typically be gained through a prolonged information gathering campaign in order to have the desired impact.
