Detects interactive root shell requests via 'sudo -i' that occur shortly after a failed Parallels appliance installation or tar extraction event containing specific error codes or configuration markers (UCP_UID=0). This pattern aligns with the exploitation chain for CVE-2026-90894, where an attacker leverages an extraction failure to escalate privileges.
Detects the use of the 'tar' utility with the '--use-compress-program' flag, where the compression program specified is not a standard system compression tool. This pattern is commonly used by attackers to execute arbitrary payloads when tar extracts malicious archives.

Detects a Parallels appliance tar archive containing a directory entry name with an embedded double-quote character followed by the --use-compress-program flag, characteristic of the ParaShells (CVE-2026-90894) tar argument-injection payload

Detects suspicious execution of the 'tar' utility spawned by 'prl_disp_service' (Parallels Desktop service) using potentially malicious command-line arguments. The rule specifically flags the use of '--use-compress-program' or the inclusion of double quotes in the command line, which are often used to achieve arbitrary code execution via shell injection in this context.

Detects the creation of files or folders containing suspicious command-line parameters associated with tar or Parallels toolchain injection, specifically looking for the 'use-compress-program' flag which can be abused for command injection.
This rule detects unauthorized modifications to the /etc/sudoers.d/ directory, specifically identifying files with a 'prl-rce-' naming pattern that contain 'NOPASSWD:ALL'. This configuration allows users to execute commands with elevated privileges (root) without requiring a password, which is a common technique used by attackers to maintain persistence and facilitate privilege escalation on Linux systems.

Detects execution of the tar utility by the prl_disp_service process with a command line pattern indicative of command injection via the --use-compress-program flag. This technique is often used to execute arbitrary commands by embedding them within the compression program argument.

Detects the 'prl_disp_service' process spawning 'tar' with the '--use-compress-program' flag set to an unconventional binary. This behavior is associated with the exploitation of ParaShells (CVE-2026-90894), where an attacker leverages the compression program hook in 'tar' to execute arbitrary commands with root privileges.

Detects JFrog Artifactory access-token issuance events on/after the suspected compromise window (2026-08-28) where the token is tied to the anonymous identity, granted administrator scope, or has no attributable initiating user, per Fastly's remediation guidance.
This rule identifies developer or contractor workstations that have Node.js/npm installed but currently lack active EDR sensor coverage (i.e., the sensor is either not onboarded or not in an active state). It employs a 24-hour grace period to filter out transient onboarding issues and ensures that the device has reported activity within the last 7 days to avoid alerting on decommissioned hardware. This gap in visibility increases the risk of undetected supply-chain malware execution and credential theft on sensitive developer endpoints.
