Detects evidence of the TinyRCT backdoor, which masquerades as legitimate VMware utilities and system binaries. The rule monitors for malicious activity including suspicious execution of vmtools.exe/vmwared.exe from ProgramData, unauthorized scheduled task creation, PerfWatson2.exe execution outside of legitimate Visual Studio installation paths, and chrome_setup.exe execution from non-standard directories.
Detects the execution of the JuicyPotato privilege escalation tool, which exploits COM server permissions to escalate a lower-privileged account to NT AUTHORITY\SYSTEM. The rule monitors process creation events for known file names, command line patterns, and specific argument structures used by this tool.
This rule detects the execution of the Windows Service Control Manager tool (sc.exe) to interact with a service containing the string 'MixedSvc' and a reference to 'Mixed Reality.exe' in the command line. This behavior may indicate an attempt to manipulate or execute suspicious services using names that masquerade as legitimate Windows Mixed Reality components.
Detects the execution of 'Mixed Reality.exe' using the 'runas' command-line utility. This pattern is often used to execute binaries with elevated privileges or alternate user contexts, which can be an indicator of potential privilege escalation or lateral movement.
Detects the spawning of svchost.exe processes from parent processes associated with Windows Mixed Reality or NvdaHelperRemote, which may indicate malicious process injection or suspicious use of GDI screen capture APIs within a masqueraded service context.
Detects potential process injection attempts targeting svchost.exe by monitoring for specific memory manipulation and object handling APIs (ZwWriteVirtualMemory, NtDuplicateObject, ZwQueryAttributesFile). Also monitors for a synthetic process event containing a specific hardcoded command line string associated with potential malicious setup activity.
This rule monitors for suspicious process behaviors and module loads involving 'Mixed Reality.exe' and 'Windows Media Player' components. It detects instances where these files are launched by 'svchost.exe', load suspicious files like 'nvdaHelperRemote.dll', or are executed as a child of 'services.exe'. These behaviors are often associated with masquerading or potential process injection techniques.
Detects the creation of a Windows service named 'MixedSvc' that points to the suspicious path 'C:\Program Files\Windows Media Player\Mixed Reality.exe'. This behavior is associated with DcRAT's Operation DragonReturn, where the malware attempts to establish persistence on the host by masquerading as a Windows Media Player component.
Detects execution patterns indicative of exploitation attempts against the CVE-2024-1086 Linux kernel vulnerability. The rule identifies suspicious usage of networking tools ('tc' with 'pedit'), namespace manipulation ('unshare'), AppArmor profile bypasses ('aa-exec'), and specific malicious binary names associated with proof-of-concept exploits for this vulnerability.
Detects the use of the 'unshare' utility to create new namespaces on Linux systems. Adversaries often use 'unshare' to perform container escapes, escalate privileges, or isolate processes from host-level monitoring. This rule specifically filters out legitimate administrative or container management processes such as systemd, containerd, and runc to reduce noise.
Detects the creation or modification of a Windows Registry Run key containing the value name 'socks5', which is indicative of SystemBC malware establishing persistence.
Detects the creation of scheduled tasks using schtasks.exe that point to the ProgramData directory, which is a common persistence location for malware like SystemBC. The rule excludes common, benign software installers and updaters that frequently use this directory to avoid false positives.
Detects the creation of a Windows service named 'MixedSvc' or services with lure-themed display names (e.g., related to 'Windows Mixed Reality') executing binaries from suspicious, user-writable directories. This pattern is consistent with the DcRAT persistence mechanism observed in the Operation DragonReturn espionage campaign.
Detects instances where the Amazon Q Developer extension spawns suspicious child processes, such as bash or npx, which may indicate the execution of arbitrary commands defined in a potentially malicious .amazonq/mcp.json workspace configuration file.
Detects process execution or file creation/modification events associated with the PACKET_EDIT_MEME (pedit_cow_demo) exploit, which targets Linux kernel vulnerabilities (CVE-2026-46331) for local privilege escalation.
Detects instances where the /bin/su binary is executed by a non-root process but succeeds in launching as the root user. This behavior is indicative of potential memory-based privilege escalation exploits, such as page cache poisoning (e.g., pedit COW variants), which allow unauthorized SUID binary execution without modifying the binary on disk.
This rule detects unprivileged processes executing Linux traffic control (tc) commands that leverage the 'act_pedit' action. Such behavior is highly unusual for non-root users and matches the exploitation pattern of the CVE-2026-46331 pedit copy-on-write (COW) kernel vulnerability, which attempts to escalate privileges via netlink socket operations.
Detects modification of /etc/ld.so.preload to register the MYRA RAT rootkit shared library (.libcache.so) for system-wide LD_PRELOAD injection. The MYRA npm package (apintergrationpost) copies libcache.so to /usr/local/lib/.libcache.so and appends its path to /etc/ld.so.preload, causing the rootkit to load into every new process on the system.
Detects anomalous behaviors associated with the Remcos RAT watchdog, specifically the execution of host processes (svchost.exe, rmclient.exe, fsutil.exe) by non-standard parent processes, the creation of specific 'WD' or 'exepath' registry keys in HKCU\SOFTWARE used for persistence configuration, and rapid respawn patterns indicating a watchdog process restart loop.
Detects the creation or modification of a Windows Registry Run key containing the value name 'socks5', which is indicative of SystemBC malware establishing persistence.
Detects the execution of 'unshare' by an unprivileged user to create a new user namespace, followed by a write operation to '/proc/self/uid_map', '/proc/self/gid_map', or '/proc/self/setgroups'. This sequence is a known technique for local privilege escalation (LPE) vulnerabilities, such as those related to unprivileged user namespaces.
