What's New (January 4, 2016)

  • Sigcheck v2.4
    This update to Sigcheck, a powerful command-line utility that reports image file and signing information, as well as information on certificates, now has an option that will report any certificates installed on the system that do not chain to one of the certificates in the Microsoft certificate trust list (CTL). It also adds the ability to take image information captured from Sigcheck on a system disconnected from the Internet and obtain VirusTotal status from one that’s connected.
  • Sysmon v3.2
    This release of Sysmon, a background service that logs security-relevant process and network activity to the Windows event log, now has the option of logging raw disk and volume accesses, operations commonly performed by malicious toolkits to read information by bypassing higher-level security features. Thanks to David Magnotti for the contribution.
  • Process Explorer v16.1
    Process Explorer now includes a column in the handle view that reports the text version of handle access masks, as well as several bug fixes including one that would result in the suspension of .NET threads when viewed via the stack dialog.

    Sigcheck, a command-line utility for displaying detailed file version information, image signing status, catalog and certificate store contents, includes updated Windows 10 certificate OIDs, support for checking corresponding MUI (internationalization strings) files for more accurate version data, and now shows the version company name as well as signature publisher for signed files.
