Statically triage a quarantined binary, no detonation, from hashes, signature chain, PE structure, strings, and a redacted sandbox report, then extract blockable indicators
Ember Robotics' EDR quarantined a binary impersonating the Windows Management Instrumentation provider host on engineering workstation ROBOTICS-ENG-07. The file carries an Authenticode signature from a certificate that was revoked months earlier. Statically triage the binary, hashes, certificate chain, PE structure, extracted strings, and a partner-shared sandbox report, without ever detonating it yourself, to identify the masquerading technique, confirm the payload is packed, and extract indicators you can actually block.
A CI build at Solstice Analytics starts failing intermittently after a routine dependency bump pulled in chart-render-utils@2.3.2. A developer notices the new version's package includes a postinstall script that wasn't in 2.3.1. Statically triage the package tarball, its integrity hash, the postinstall script, and its decoded payload, without ever running it, to determine what changed and what it does.
A paralegal at Northbridge Legal Group opens an emailed invoice attachment; nothing visibly happens, and she reports it as suspicious rather than closing it and moving on. EDR flagged regsvr32.exe running with unusual arguments moments later. Statically triage the Office document with open-source macro-analysis tooling to reconstruct exactly what it was designed to do, without ever opening it in Office yourself.
Solenne Pharmaceuticals' EDR flags a signed-looking utility, brand_refresh.exe, reading a routine-looking corporate logo image and then allocating executable memory, despite the image opening normally in every viewer with no visual defect. Statically triage the loader binary and the image file together, without detonating either, to determine how a payload is being smuggled inside what appears to be an ordinary PNG.
Brightwell Media's EDR quarantines a freshly-downloaded screen-recording tool installer for tripping four heuristics at once: it's packed, it spawns cmd.exe and powershell.exe during install, and it writes a Run-key entry. Statically triage the packed installer, its Authenticode chain, and the vendor's own deployment documentation to determine whether this is a genuine compromise or a legitimate installer behaving exactly as documented.
A CAD updater on a Talon Aerospace engineer's workstation carries a fully valid, unrevoked Authenticode signature from a real, known CAD vendor. Statically triage the certificate chain, the RFC3161 counter-signed timestamp, and the vendor's own public disclosure timeline to determine why a cryptographically valid signature does not mean this file is trustworthy.
An administrative staff member at Fairhaven University extracts a zipped 'enrollment report' and double-clicks what looks like an Excel file. EDR flags mshta.exe launching moments later. Statically parse the underlying .lnk shortcut's embedded target, arguments, and icon spoofing, then the HTA payload it launches, without ever executing either yourself.
A server at Aldergate Insurance keeps re-establishing an outbound beacon after every reboot, but file-integrity monitoring shows zero new files written to disk anywhere on the host. Statically enumerate the WMI repository's persistent event-subscription classes and the corresponding Sysmon WMI-activity events to reconstruct a persistence mechanism that never touches disk.
A front-desk workstation at Ridgeline Hospitality runs reservation_helper.exe, a binary whose declared file size doesn't match the sum of its own PE section table. Statically triage the packed loader's overlay data, its in-memory unpacking routine, and a partner-shared decoded configuration to determine what commodity crimeware is being rented and deployed against this point-of-sale environment.
A file-integrity scan of Cobalt Ridge Realty's public web server turns up a PHP file sitting among routine cache files, with a modification timestamp that matches its neighbors almost too well. Statically read the PHP source, its ROT13-obfuscated function call, and the web server's access log to determine what this file actually does and who has been using it.
