This rule detects a process initiated by Node.js or NPM performing a DNS lookup for known malicious domains while simultaneously accessing sensitive local files such as SSH keys, AWS credentials, browser cookies, browser login data, or bash history. This pattern is indicative of a post-compromise activity where an adversary leverages a JavaScript runtime to perform credential theft and communicate with C2 infrastructure.
This rule detects the execution of obfuscated PowerShell commands (encoded) that subsequently establish an external network connection and perform process injection within a short timeframe (120 seconds). This behavior is characteristic of malicious staged execution, where a PowerShell script acts as a dropper or loader to fetch secondary payloads and inject them into other processes for evasion.
This rule correlates three suspicious behaviors occurring within 10 minutes: a non-root process identified as 'bumsrakete' executes, this process accesses the sensitive kernel memory file '/dev/mem', and subsequently, a root process is spawned that is not a standard privilege escalation utility (such as sudo, su, etc.). This sequence of events is highly indicative of potential malicious activity, such as kernel-level exploitation or unauthorized privilege escalation.
Detects unauthorized modification of file flags on core system binaries (e.g., /bin, /sbin, /usr/bin) followed by write/modification operations. This behavior is indicative of an attacker attempting to bypass immutable flags to modify or replace critical system files, often seen in rootkits or malware to achieve persistence or tamper with system integrity.
This rule detects potential supply chain compromise involving typosquatted npm packages. It monitors for the execution of npm packages with names closely resembling legitimate libraries (e.g., 'thirdweb', 'rainbownkit'), followed by suspicious post-install scripts that attempt to initiate network connections to known malicious domains or modify sensitive files.
Detects suspicious child process execution originating from Node.js environments. The rule monitors for common package installation scripts (e.g., postinstall) or suspicious command-line indicators associated with known malicious patterns, such as domain connections, library masquerading, and unauthorized script execution.
This rule detects when a Node.js process accesses sensitive files associated with SSH configurations, private keys, or package manager credentials (such as .npmrc or .pypirc). Such behavior is highly unusual for legitimate web application processes and may indicate an attacker attempting to steal credentials or secrets from a compromised system.
Detects network connections or DNS queries to ErrTraffic Beer cluster domains impersonating AI platforms (ChatGPT, Google Antigravity) delivering DanaBot/HijackLoader via BSOD or reCAPTCHA ClickFix lures, and subsequent browser-spawned PowerShell execution.
Detects modifications to Windows Registry Run or RunOnce keys initiated by ConfigurationRemotingServer.exe. This activity is indicative of persistence mechanisms where an executable is registered to launch automatically upon user logon or system startup.
Detects execution of winget.exe with configuration arguments pointing to external or potentially suspicious file extensions like .jpg or .txt. This behavior is indicative of an adversary attempting to execute arbitrary code or scripts masquerading as configuration files, leveraging the Windows Package Manager 'configure' functionality to bypass security controls or execute malicious payloads.
