Detects the macOS Script Editor (`Script Editor.app`) launching child processes or initiating network connections. This behavior can indicate the execution of a malicious AppleScript used to download secondary payloads or execute arbitrary commands, as seen in campaigns delivering stealers like MacSync and Odyssey.

This query detects execution of processes related to Visual Studio Code extension signing or caching that involve known Glassworm-compromised extensions. Based on indicators published by KOI (October 20, 2025), it identifies suspicious .vsix package operations potentially associated with self-propagating malicious VSCode extensions observed in OpenVSX and Microsoft VSCode marketplaces.

To extract vscode extension version I used this the https://detections.ai/rules/924f7b5f-d8df-4eed-ba06-08c657f65891.

Detects network connections to blockchain APIs that are indicative of EtherHiding techniques, specifically those used by UNC5342 to retrieve malicious payloads. It identifies connections to domains containing keywords like 'explorer', 'block', 'cypher', 'eth', 'bit', 'coin', or 'crypto', combined with suspicious URL patterns such as 'eth_call' (a read-only function call for smart contracts) or 'apiKey=freekey' (a common free API key used by threat actors).

This rule detects when a user is added to the local 'admin' group on a macOS system using either the `dscl` or `dseditgroup` command-line utilities. It specifically looks for command-line arguments indicative of adding a user to the 'admin' group. There is a whitelist for legitimate MDM solutions like 'jamfmanager' to reduce false positives.

This rule detects a sequence of events indicative of a potential macOS ClickFix attack. It looks for a base64 encoded command executed by 'bash' or 'zsh', immediately followed (within 10 seconds) by a 'curl' command that initiates a network connection to a URL. The rule specifically excludes a whitelisted curl command to reduce false positives. The correlation of base64 execution, a subsequent curl command, and a successful network connection to the domain extracted from the curl command suggests an attempt to download and execute malicious content, possibly after decoding it.

Detects potential exploitation of the TARmageddon vulnerability (CVE-2025-62518) by identifying multiple writes to sensitive configuration files by the same process in a short time frame. This behavior can indicate a file overwrite attack where a malicious TAR archive smuggles and extracts a secondary file to hijack build processes or application configurations.

Detects a sequence of events where a user visits a Cloudflare Pages URL (*.pages.dev) and shortly after, a suspicious command (mshta, powershell, or curl) is executed. This pattern is consistent with the UNC5142 threat actor's TTP of using social engineering lures hosted on Cloudflare Pages to trick users into running malicious commands.

Detects the interaction with macOS XPC services such as 'nsurlstoraged' and 'CoreSpotlightService' via 'xpcproxy'. This technique is used by malware like AMOS and Odyssey Stealer to blend malicious activity with legitimate system processes for stealth and persistence.

This rule detects potential command and control (C2) activity by identifying devices that first query 'api.ipify.org' (often used by malware to determine external IP addresses) and then subsequently establish an outbound network connection to a non-private IP address on port 7712. This sequence of events can indicate a compromised host attempting to beacon out to a C2 server after initial reconnaissance.
