Static Token And Credential Scanner

What’s it?

STACS is a YARA powered static credential scanner
which suports binary file codecs, research of nested archives, composable rulesets
and forget about lists, and SARIF reporting.

What does STACS support?

In recent years, STACS helps recursive unpacking of tarballs, gzips, bzips, zips, and xz
recordsdata. As STACS works on detected file varieties, moderately than the filename, propriatary
file codecs in keeping with those varieties are routinely supported (comparable to Docker photos,
Android APKs, and Java JAR fles).

Who should use STACS?

STACS is designed to be used by means of any groups who liberate binary artifacts. STACS supplies
builders the facility to routinely take a look at for unintended inclusion of static
credentials and key matter subject matter of their releases.

However, this doesn’t counsel STACS can’t be in agreement with SaaS ways, undertaking
instrument, and even supply code!

For example, STACS can be utilized to appear out static credentials in Docker photos uploaded
to private and non-private container registries. It can be used to appear out credentials
by chance compiled in to executables, applications for cellular gadgets, and “undertaking
archives” – corresponding to these utilized by Java tool servers.

How does it paintings?

STACS detects static credentials the usage of “rule packs” equipped to STACS when run. Those
rule packs outline a number of YARA regulations to run in opposition to recordsdata equipped to STACS. When a
fit in opposition to a rule is located, a “discovering” is generated. Those findings constitute
possible credentials inside of a file, and are reported on for a developer to remediate
or “forget about”.

If the discovering is located to be a false positive – this is, a fit on one thing different
than an actual credential – the developer can generate a number of “forget about lists” to ensure
that those fits don’t seem in long term evaluations.

The true energy from STACS comes from the automated detection and unpacking of nested
archives, and composable forget about lists and rule packs.

Disregard about lists?

In an effort to permit versatile and collaborative utilization, STACS helps composable forget about
lists. This permits for an forget about report to incorporate different forget about lists which permit
composition of a “tree of ignores” in keeping with organisational tips. Those forget about
lists are particularly helpful in organisations the place lots of the an identical frameworks or
merchandise are used. If a workforce has already marked a discovering as a false positive, different
groups get the good thing about not having to triage the identical discovering.

Rule packs?

Throughout the identical means as forget about lists, rule packs also are composable. This permits an
organisation to outline a baseline algorithm to be used by means of all groups, whilst however
permitting groups to take care of rulesets particular to their merchandise.

How do I take advantage of it?

One of the best ways to make use of STACS is the usage of the Docker photos printed to Docker Hub.
However, STACS will also be put in immediately from Python’s PyPI, or by means of cloning this
repository. See the related sections underneath to get began!

A cloud based totally provider is coming briefly which permits integration immediately in bring together
and liberate pipelines to permit detection of static credentials earlier than liberate!


The usage of the published photos, STACS can be utilized to scan artifacts in an instant! The STACS
Docker photos supplies a lot of quantity mounts for recordsdata sought after to be scanned to be
fixed immediately into the scan container.

For example, to scan the entire thing within the supply folder, the next command can also be
run (Docker should be put in).

docker run 
--mount type=bind,supply=$(pwd),function=/mnt/stacs/enter

By the use of default, STACS will output any findings in SARIF layout immediately to STDOUT and in
order to stay issues orderly, all log messages it is going to be despatched to STDERR. For extra tricky
use instances, a lot of different quantity mounts are equipped. Those permit the person to keep watch over
the rule of thumb of thumb packs, forget about lists, and a cache directories to make use of.


STACS will also be put in immediately from Python’s PyPi. This provides a stacs command
which is able to then be utilized by builders to scan tasks immediately of their native
construction environments.

STACS can also be put in immediately from PyPi the usage of:

Please Word: The PyPi liberate of STACS does not include any regulations. Those may even
want to be cloned from the group regulations repository
for STACS to paintings!


Is there a hosted taste of STACS?

Now not alternatively. However, there are plans for a hosted taste of STACS which can also be simply
built-in into supply bring together ways, and which incorporates further prebuilt rule
packs and forget about lists.

What do I do about false positives?

Sadly, false positives are an inevitable side affect throughout the detection of
static credentials. If regulations are too granular then rule maintenance turns proper right into a burden
and STACS would perhaps overlook credentials. If regulations are too coarse then STACS would perhaps generate too
many false positives!

In an effort to lend a hand, STACS supplies a lot of gear to lend a hand with lowering the quantity
of false positives which make it into ultimate evaluations.

Essentially, STACS supplies a mechanism which permits consumers to outline composable forget about
lists which allow a number of findings to be “now not well-known”. Those regulations can also be as coarse as
ignoring all recordsdata in keeping with a development, or as granular as a selected discovering on a
explicit line of a file.

This data is routinely propagated by means of into evaluations, so “now not well-known” findings
it is going to be marked as “suppressed” in SARIF output whilst additionally at the side of the cause of the
forget about within the output for monitoring.

How do I view the consequences?

In recent years, the one output layout is SARIF v2.1.0. There are a variety of audience
to be had which make this knowledge more straightforward to be told, comparable to this nice internet based totally viewer from Microsoft. An instance of the findings from a Docker container
symbol has been incorporated underneath:

The efficiency is in truth, in truth unhealthy when running in Docker on macOS!

Sadly, this seems to be because of a limitation of Docker Desktop for Mac. I/O
for bind mounts is in truth, in truth gradual.
