Detects high-volume outbound SYN packet bursts from internal hosts to external networks, excluding known service ports. This behavior is indicative of a compromised host acting as part of a botnet conducting a SYN flood Denial of Service attack.
Detects malicious SQL injection attempts targeting WordPress REST API endpoints that attempt to forge post parameters by injecting self-referential cycles. The pattern specifically looks for 'UNION SELECT' combined with 'author_exclude' and manipulated 'post_parent' values, matching known exploitation patterns for the wp2shell vulnerability (CVE-2026-63030 / CVE-2026-60137).
Detects connections to the local CDP WebSocket server on port 18907 tied to the chrome_remote/browser_remote backdoor family, used for session-cookie theft, password capture, browser API hooking, and MetaMask/dApp manipulation.

Detects unauthorized write or modification access to core Windows boot-related files such as bootmgr, winload.efi, and the BCD store. This activity is indicative of destructive wiper malware attempting to render the operating system unbootable to prevent recovery, a technique observed in the TOKYOCORE wiper campaign.
Bulk file-write activity by a single process within a 1-minute window, filtered to exclude common high-volume legitimate processes (backup agents, AV scanners, installers, sync clients) and correlated with the appearance of ransom-note-style filenames or unusual/new file extensions in the same window, indicative of ransomware encryption post-RAT access.
Detects cloning and building xmrig-proxy from source (git clone + cmake/make), used by JadeProx operators to relay cryptomining traffic from compromised hosts behind a single mining pool connection. Build commands must specifically reference the xmrig-proxy repository or directory to reduce false positives from generic development builds.
Detects TOKYOCORE ransomware via high-confidence identity strings; a single match is sufficient
This rule detects potential ransomware activity by monitoring for specific PowerShell commands associated with file encryption (AES, CreateEncryptor, TransformFinalBlock) and suspicious file manipulation patterns, such as mass renaming of files with common ransomware extensions or the dropping of known ransom note filenames.
Generic rule content from file: TOKYOCORE Wiper Clearing UEFI Secure Boot Keys via PowerShell
Detects the use of the 'net.exe' command to reset the password of a local administrator account. This behavior is specifically associated with the NoEscape ransomware, which utilizes this command as part of its impact-oriented activity to prevent authorized access to the compromised system.
Detects the deletion or renaming of critical Windows forensic artifacts (pagefile.sys, hiberfil.sys, swapfile.sys) typically performed by the TOKYOCORE wiper to impede forensic analysis and system recovery.
Bulk file-write activity by a single process within a 1-minute window, filtered to exclude common high-volume legitimate processes (backup agents, AV scanners, installers, sync clients) and correlated with the appearance of ransom-note-style filenames or unusual/new file extensions in the same window, indicative of ransomware encryption post-RAT access.
Detects the load of RstrtMgr DLL (Restart Manager) by an uncommon process.
This library has been used during ransomware campaigns to kill processes that would prevent file encryption by locking them (e.g. Conti ransomware, Cactus ransomware). It has also recently been seen used by the BiBi wiper for Windows.
It could also be used for anti-analysis purposes by shut downing specific processes.

Detects potential exploitation attempts targeting WordPress sites, specifically identifying unauthenticated REST API batch requests that attempt to forge posts with post_status 'parse' and post_type 'request' while including self-referential post_parent cycles. This pattern is associated with recent vulnerabilities enabling remote code execution.
Detects [embed] shortcode content submitted to WordPress that references invalid or anonymous local post IDs, used in the wp2shell chain to forge oEmbed cache database rows as a render-time write primitive.

Build commands must specifically reference the xmrig-proxy repository or directory to reduce false positives from generic development builds.
Tier 5 catch-all: flags files exhibiting a broad spread of TOKYOCORE-related strings across identity, C2, ransom-note/branding, destructive, file-operation, data-theft, and persistence clusters, regardless of which specific cluster dominates
Detects the creation of a specific wallpaper file ('image_danger.jpg') associated with the GigaWiper malware family, which is indicative of a system defacement attempt during the destructive phase of an attack.
