There are a couple places where this was an issue.
The first place was in the filesystem plugin where it was only checked that it
existed, and not that it was an actual file.
The second was a lack of try and catch on the parse call in config.cpp.
Both of those issues are addressed in this diff.
After the merge you need to include yara.h after fsevents.h on OS X.
Apaprently DECLARE_SUBSCRIBER() was dropped during the merge, which
meant that attempts to find the subscriber would fail, throwing an
unhandled exception.
Fix the table spec to use the new table name.
Must use recursive on Linux.
In order to watch a directory you must set recursive to true in
SubscriptionContext under Linux.
Currently only for OS X, will port to others soon.
Also need to add tests.
Remove old comment and add loading message.
Implement YARA table for Linux.
Use mask properly.
Use the various masks to specify the kinds of events we are interested
in. This removes the need to do the dirty "DELETED" check when the event
fires.
Make getYARAFiles return a const map.
Switch to LOG(WARNING) and emit error number.
Add vim .swp files to .gitignore.
Add yara_utils.(c|h).
Start to condense common code between the Linux and Darwin YARA tables
into a yara_utils.h. Right now it includes a function to compile rules
and store the results back in the map, indexed by category. It also has
the callback used by YARA when a rule is processed. I can not move much
more than that for the row creation code because the structures used in
the event callback are slightly different.
Include a better error message.
The errors are still printed by the compiler callback, but this will
allow my future work to return a Status from the event initialization to
print a useful message in summary.
Make Subscriber init() return Status.
Each EventSubscriber::init() now returns a Status. If the init() fails
for any reason the EventSubscriber is still stored but the failure is
tracked.
EventSubscribers now have a state member, which represents the current
state of the subscriber. The current supported states are:
uninitialized, running, paused, failed. Currently the only meaningful
ones are running and failed, but I put paused in there as a
forward-looking feature.
Subscriptions now have a subscriber_name member. This is used in
EventPublisherPlugin::fire() as a lookup to get the EventSubscriber and
check the state. If the EventSubscriber is not running the event will
not fire.
Only the EventSubscribers on OS X are using this. I'll do the Linux
implementation next.
Chase the init() changes to Linux.
This brings the Linux YARA table in line with the OS X one.
Require a EventSubscriberID when creating a subscription.
Now that Subscriptions are "tied" to EventSubscribers you must create a
Subscription with the name of the Subscriber it is for. This is because
when the event fires the list of Subscriptions is walked and the name is
used to lookup the EventSubscriber and make sure it is in the running
state.
Fix various tests.
Some tests would fire an event with only a Subscription, which is no
longer a valid thing to do. For these tests an EventSubscription is
created and registered in the EventFactory.
When Subscriptions are created pass the name of the EventSubscriber to
them. In some cases where no event is ever fired it is fine to pass a
bogus name.
Fix inotify tests.
Move a test down so the class is defined and make sure to create an
EventSubscriber and use it properly.
Add support for yara to provision.sh.
Right now this grabs yara 3.3.0 and applies the patch to fix min() and max(),
which is commit fc4696c8b725be1ac099d340359c8d550d116041 in the yara repo.
This has been tested under Ubuntu 14.04 only.
Remove NOMINMAX.
This is no longer necessary after the patch was backported to 3.3.0.
Revert "Add support for yara to provision.sh."
This reverts commit a8bd371498c0979f070adeff23d05571882ac3f1.
Use vendored YARA code in third-party.
This switches to using the YARA code contained in third-party, including
the patch to fix min/max macros.
Fix mismerge.
Remove unused function after merge.
Well, soon to be unused as soon as I fix up the Linux YARA table. ;)
Chase config changes.
Make the Linux YARA table use ConfigDataInstance along with files() and
yaraFiles().
properly query IORegistry
remove fde_status implementation from block_devices
scaffolding for disk_encryption table
add disk_encryption table schema
implement disk_enryption table for OS X
clang-format the source
add newline at the end of disk_encryption.table
add device prefix to the bsd_name
provide link to apple's open source
renamed fde_status to disk_encryption, more readable code
preserve alphabetical ordering
tiny formatting fix
change header comment back to original
Apparently if it ain't broke, don't fix it. Opera support seems to be exactly
the same as Chrome except changing the path. The file is basically just copied
with Chrome replaced with Opera + path change.
Added cross platform functionality to chrome and opera. Plus abstracted it in
more general functions that can be used for other chrome based browsers.
The extended attributes table used to have its own parsing algorithm
and functions. These are unnecessary because osquery has built in PLIST parsing
provided by the operating system. Thus, I've moved the code to using that and
removed the xattr tests because they only tested the now non-existant parsing.
Further, the files have been renamed so they should now play nice with the
included profiler.
