This rule detects the execution of the MeshAgent remote administration tool from a temporary directory followed by a network connection to known malicious infrastructure within a 15-minute window. This behavior is indicative of unauthorized remote access setup or C2 activity using a legitimate remote management utility.
Detects the execution of the 'fanout.sh' utility from the /tmp directory, which subsequently spawns 'sshpass' child processes to perform rapid, non-interactive SSH authentication attempts ('StrictHostKeyChecking=no') against multiple internal hosts within a 10-minute window. This behavior is indicative of automated lateral movement, specifically observed by threat actor UNC6240.

This rule monitors for file and process creation events associated with known MD5 and SHA256 hashes linked to the Vidar infostealer malware.

Matches known Vidar Stealer sample SHA256 hashes spanning versions 2.0 through 3.4 as identified by Zscaler ThreatLabz

Detects Vidar Stealer v2.x-3.x custom VM bytecode interpreter used to deobfuscate strings via a fetch-decode-execute loop with sparse opcode dispatch and single accumulator
Detects Vidar's custom stream cipher used for string/config decryption: FNV-1a mixing of the VM-derived key combined with golden-ratio nonce mixing and per-build ARX round constants

Detects network traffic associated with the NPM Btree malware campaign, specifically identifying command-and-control (C2) polling activities directed toward blockchain RPC endpoints like Alchemy and Infura. The rules monitor for specific API keys, C2 smart contract addresses via 'eth_call' JSON-RPC requests, and overall traffic patterns to known malicious infrastructure.
Detects Microsoft 365 Exchange MailItemsAccessed operations performed by a specific ClientAppId and AppId known to be associated with an exfiltration toolkit. This activity indicates unauthorized access to mail items, consistent with data harvesting efforts.
Detects high-volume file access or download operations in SharePoint or OneDrive performed by common scripting libraries and client user agents, which may indicate automated data exfiltration.
Detects Node.js processes executing system-level reconnaissance (e.g., CPU, memory, hostname, uptime enumeration) followed by network connections to known exfiltration endpoints (Slack, Telegram API). This behavior aligns with identified npm malware campaigns using host fingerprinting for target selection and data exfiltration.
Detects the execution of the Windows Workspaces Broker process (wkspbroker.exe) when it loads a library (DLL) from a path within the RemoteApp Gateway directory under LOCALAPPDATA. This behavior is associated with DLL side-loading techniques used to execute malicious payloads such as the Xray-core implant.
