Microscope is a utility that aids in identifying vulnerable or unwanted software installed on a system. It is designed for easy integration into a CI/CD pipeline, and has the ability to do things like scan docker containers while they aren't even running. Simply obtain a database of files/packages you want to scan for, and Microscope will do the rest.

If you have Go installed, run these commands:

git clone github.com/ajblkf/microscope
cd microscope
go install ./cmd/microscope

This will install the microscope command locally. In order to have it system wide, you can move it to /usr/local/sbin or a similar location.

Microscope is distributed as a statically linked binary through the releases tab on this repository. You can save it as /usr/local/sbin/microscope to get the microscope command system-wide.

• -pkgdb FILE: Specify a deny list of unwanted packages
• -db FILE: Specify a deny list of unwanted files
• -files FILES...: Recursively scan a list of files or directories
• -pkg: Scan packages installed on the system
• -npm PROJECT-DIRECTORY: Scan dependencies of an NPM project
• -docker-files CONTAINER FILES...: Scan files installed in a docker container
• -docker-pkg CONTAINER: Scan packages installed in a docker container
• -archive-files ARCHIVE FILES...: Scan files contained in an archive
• -archive-pkg ARCHIVE: Scan packages installed in an archive of a filesystem
• -docker-npm CONTAINER PROJECT-DIRECTORY: Scan dependencies of an NPM project inside of a docker container

The package deny list is a CSV file with two columns: a package identifier, and a reason why the package is in the list. The package identifier is formatted as follows:

NAME-VERSION-RELEASE:REPOSITORY

If any of these parts are left blank, they will match anything.

Here is a sample deny list that detects Firefox version 100, which is vulnerable to CVE-2022-1802:

firefox-100.0-:, Vulnerable to CVE-2022-1802
firefox-100.0.1-:, Vulnerable to CVE-2022-1802
firefox-100.0.2-:, Vulnerable to CVE-2022-1802

The file deny list is a CSV file with two columns: a hexadecimal encoded sha256 sum of the file to detect, and a reason why the file is in the list.

Here is a sample deny list that detects files consisting of "hello\n":
