Detects a potentially suspicious powershell script executions from temporary folder
Detects AWS OIDC role assumption by a GitHub workflow running on a ci-sync-<6 chars> branch followed within an hour by Secrets Manager reads using the same session credentials, as seen in the Gheist campaign.
Detects a file creation event for any executable inside the "tmphtml" staging
directory beneath the AOMEI Backupper installation path, where the creating process
is Backupper.exe. The application stages popup resources here before relocating them
to html\; a genuine promotional bundle contains no executables, so an .exe written
to this path indicates a tampered bundle.

Detects post-exploitation activity targeting PaperCut servers, including shells spawned by the PaperCut Java process or the creation of malicious files (such as .class files in lib/ or .txt webshells in custom/web/) by the Java application.
Detects a high volume of authentication failures followed by a successful authentication from the same source IP address against edge devices like FortiGate or Palo Alto GlobalProtect within a specific time window.
Detects msiexec.exe spawning scripting or programming engines (such as PowerShell or Python) that perform LDAP directory searches and establish outbound external network connections within a specific time window.
Detects a potential multi-stage social engineering attack where a user first receives a high volume of emails (mail-bomb burst) within a short window, followed shortly by an external Microsoft Teams message from a suspicious throwaway tenant using an IT help desk display name.
Detects a sequence where PowerShell downloads an .msi file from Azure Blob storage (blob.core.windows.net), followed by msiexec.exe spawning PowerShell on the same device within 30 minutes.
The KQL rule detects a ClickFix-style technique in which script hosts reference files disguised with an f_* naming pattern in browser profile cache directories. The key behavioural indicators are:
- Script hosts such as wscript.exe, cscript.exe, and mshta.exe referencing browser cache paths.
- Suspicious parent processes, including Explorer, command shells, and script hosts.
- Creation, modification, or renaming of t.vbs under the user's Temp directory by Windows Script Host.
- Script hosts such as wscript.exe, cscript.exe, and mshta.exe referencing browser cache paths.
- Suspicious parent processes, including Explorer, command shells, and script hosts.
- Creation, modification, or renaming of t.vbs under the user's Temp directory by Windows Script Host.

CVE-2026-85706 is a critical path traversal vulnerability affecting both GitLab Community Edition (CE) and Enterprise Edition (EE).
The Flaw: The issue originates in the repository commits/files API. The API processes file paths and reads them from the disk before verifying user authentication or restricting the path to the designated repository folder.
The Impact: A remote attacker can exploit this weakness with a single HTTP request. Because it requires zero credentials and no user interaction, attackers can easily read arbitrary, potentially sensitive files directly from the host GitLab server.

Detects execution of BlackX UEFI bootkit installer components, renamed helper binaries acting as payloads (such as jcef_helper.exe renamed to googleupdate.exe), or known malicious file hashes associated with BlackX campaigns.
Detects execution of BlackX UEFI bootkit installer components, renamed helper binaries acting as payloads (such as jcef_helper.exe renamed to googleupdate.exe), or known malicious file hashes associated with BlackX campaigns.
Detects the execution of two or more distinct Active Directory discovery, credential extraction, or coercion tools (such as NetExec, Kerbrute, noPac, PetitPotam, SoftPerfect Network Scanner, or Impacket scripts) on the same device within a 1-hour window.
Detects WinRAR or 7-Zip extracting an archive with a hard-coded password supplied via command line from a cmd.exe batch parent, using switch patterns associated with the RareWolf AnyDesk dropper.
Detects the execution of the Chisel tunneling tool configured as a client building a reverse SOCKS tunnel with flags such as TLS verification disabled, keepalive, or authentication, or communicating with a known C2 endpoint.
Detects Salat Stealer dropping and executing copies of Lightshot.exe in trusted directories such as Windows NT, Edge, and Chrome application paths, as well as process spawn chains involving masqueraded Lightshot executables.
Detects a sequence of events on Linux hosts involving a remote interactive or network logon from an external IP, followed within 5 minutes by root-level process execution, and subsequently within 2 hours by an outbound SSH connection to a private or known attacker IP. Also includes a separate branch for direct logons from known malicious IPs.
Detects a VS Code-family editor or extension host modifying ~/.ssh/authorized_keys, or shell commands appending the svc-telemetry label / embedded Ed25519 key, as used by the trojanized anthropic.claude-code extension.
Detects the execution of Microsoft Quick Assist followed by a different remote access tool (RAT) or remote monitoring and management (RMM) utility on the same device within a 24-hour window, which may indicate adversary staging or persistence establishment.
Correlates a CVE-2026-76504 encoded /%6a_security_check login POST with a follow-on /dataservice/admin/user request from the same client to the same vManage within 10 minutes. Summarized and sorted by follow-on count.
