This rule detects the execution of Mimikatz or the use of its specific command-line arguments, which are strongly indicative of credential dumping activities, often used for post-exploitation lateral movement or privilege escalation.
This rule detects established outbound network connections to 'devtunnels.ms', which is a legitimate service often abused by adversaries to tunnel RDP traffic and bypass network security controls or firewall restrictions. This behavior is indicative of unauthorized remote access setup.
This rule detects processes accessing or files being interacted with that are known to contain sensitive information, including API keys, credential files, database configurations, and cryptocurrency wallets. It monitors command-line activity for utilities like python, bash, and grep interacting with sensitive strings, and tracks file system access to sensitive paths.
Detects the use of ScreenConnect client processes initiating rapid outbound network connections to multiple distinct devices within a short timeframe (1 hour). This behavior is often indicative of unauthorized lateral movement, automated discovery, or mass-deployment of remote access sessions using legitimate administrative software.
Detects a sequence of activity involving the use of the MySQL 'AES_ENCRYPT' function followed by a 'DROP TABLE', 'DROP SCHEMA', or 'DROP DATABASE' command on the same host within a 30-minute window. This behavior is consistent with extortion tactics, such as the JADEPUFFER campaign, where attackers encrypt sensitive database records and delete the original tables to compel ransom payments.
Detects the ScreenConnect remote access binary spawning suspicious child processes often associated with lateral movement, system reconnaissance, or anti-forensics activity (such as deleting shadow copies, modifying boot configuration, or using administrative tools for remote command execution). This behavior is highly indicative of an adversary abusing legitimate RMM software to execute post-exploitation commands.
Detects the execution of 'SimpleService.exe' when the binary is located within a restricted subdirectory associated with JWrapper-Remote Access. This pattern may indicate the execution of unauthorized or restricted remote access tools.
Detects the addition of a user to the 'Domain Admins' group using common administrative command-line tools such as net group, Add-ADGroupMember, dsadd, or net localgroup. This serves as a proxy indicator for potential privilege escalation.
Detects instances where a Langflow process spawns a Python process using command-line arguments involving base64 decoding or character-based execution, which is often indicative of malicious code injection or shellcode execution.
Detects file creation events initiated by ScreenConnect (ConnectWise Control) client processes. ScreenConnect is a legitimate remote support and RMM tool often leveraged by adversaries for remote access or as a secondary persistence mechanism. Monitoring file creation by these processes may indicate the installation of additional tools, scripts, or malware via a remote support session.
