Detects download of certain file types from hosts with dynamic DNS names (selected list)
Detects the extraction of password protected ZIP archives with suspicious file names. See the filename variable for more details on which file has been opened.
Detects usage of bitsadmin downloading a file with a suspicious extension
Detects the execution of certutil with certain flags that allow the utility to download files.
Detects the execution of certutil with certain flags that allow the utility to download files from direct IPs.
Adversaries can use curl to download payloads remotely and execute them. Curl is included by default in Windows 10 build 17063 and later.
Detects execution of findstr with the "s" and "i" flags for a "subfolder" and "insensitive" search respectively. Attackers sometimes leverage this built-in utility to search the system for interesting files or filter through results of commands.
Detects usage of "IMEWDBLD.exe" to download arbitrary files
Detects the execution of "Ldifde.exe" with the import flag "-i". The can be abused to include HTTP-based arguments which will allow the arbitrary download of files from a remote server.
Detects the use of Windows Defender MpCmdRun.EXE to download files
Detects the creation of a scheduled task using schtasks.exe, potentially in combination with curl for downloading payloads and PowerShell for executing them.
This facilitates executing malicious payloads or connecting with C&C server persistently without dropping the malware sample on the host.

This rule detects network traffic to the command and control (C2) domain 'sfrclak.com', which is associated with compromised versions of the Axios npm package (specifically 1.14.1 and 0.30.4). This traffic represents the first stage of activity where dropper scripts on an affected endpoint attempt to communicate with their C2 server.
This rule detects the creation, writing, or renaming of specific files associated with the compromised Axios npm package versions 1.14.1 and 0.30.4. Upon installation, the postinstall script of these compromised packages deploys dropper scripts to download and install a remote access trojan on Mac, Linux, or Windows endpoints. The rule specifically looks for file paths indicative of these dropper activities across different operating systems.
This rule detects the first stage of activity once a compromised endpoint runs the affected Axios package (versions 1.14.1 and 0.30.4). It specifically looks for process creation events where the command line contains a call out to the C2 domain 'sfrclak.com'. This indicates the dropper scripts attempting to establish communication with their command and control server.
On March 11, 2026, the global medical technology giant Stryker experienced a severe cyberattack when Iranian-linked hackers called Handala Hack affiliated with Iranian Ministry of Intelligence and Security (MOIS) used wiper malware to permanently erase data from its network. Based On the List of IOC’s seen from the previous attacks from the threat group I’ve done threat hunt.
Detects network connections to a suspicious Vercel application URL ('vscode-ext-git.vercel.app') combined with file events initiated by command-line shells (cmd.exe, powershell.exe, pwsh.exe) using 'curl' in their command line. This correlation suggests potential ingress tool transfer or data exfiltration attempts.
Detects network connections to a suspicious Vercel application URL combined with file events initiated by command-line shells (cmd.exe, powershell.exe, pwsh.exe) using 'curl' in their command line. This correlation suggests potential data exfiltration attempts as noted in the linked blog post.
This rule detects unusual network connections from processes to legitimate service endpoints that are commonly abused for Command and Control (C2) activities (LOLC2). It specifically looks for connections to services like Telegram, Slack, Discord, GitHub, Google APIs, Pastebin, Dropbox, and others, originating from processes that are not recognized as legitimate applications for those services, and not from common system processes or standard program file paths. This helps identify potential adversary communication channels masquerading as legitimate traffic.

This detection helps you spot activity linked to Pawn Storm PRISMEX (CVE-2026-21509 / CVE-2026-21513) using the specific indicators in the linked source. It is written to be high confidence by focusing on exact versions, domains, paths, or file fingerprints that were observed in the reporting. A match does not prove a system is compromised by itself, but it is a strong reason to investigate. Confirm the affected host and user, check whether the access was expected, and review nearby activity for follow-on steps like additional downloads, new persistence, or repeated connections. Use the source link to support incident notes and.
Detects network activity consistent with a user attempting to download or install OpenClaw or a known variant — an open-source AI agent family classified as a Potentially Unwanted Application (PUA). Monitors for access to OpenClaw distribution URLs including GitHub releases, the install script endpoint, raw GitHub content, and npm registry paths for known variants. Also detects variant names appearing in process command lines at the time of a network connection, covering alternative package managers and runtimes such as Bun, pnpm, Yarn, and Deno in addition to traditional browsers and shell tools. Covers 33 known variants of the OpenClaw family including Clawdbot, Moltbot, Ironclaw, MalClaw, and others.
