MIG: Mozilla InvestiGator

MIG is Mozilla's platform for investigative surgery of remote endpoints.

⚠️ Deprecation Notice ⚠️

Mozilla is no longer maintaining the Mozilla InvestiGator (MIG) project.

Mozilla is also no longer making use of this code internally.

You are welcome to use this code as is with no warranty. Please fork it to continue development.

Quick Start w/ Docker

You can spin up a local-only MIG setup using docker. The container is not suitable for production use but lets you experiment with MIG quickly, providing a single container environment that has most of the MIG components available.

To pull from Docker Hub:

$ docker pull mozilla/mig
$ docker run -it mozilla/mig

Or, if you have the source checked out in your GOPATH you can build your own image:

$ cd $GOPATH/src/github.com/mozilla/mig
$ docker build -t mozilla/mig:latest .
$ docker run -it mozilla/mig

Once inside the container, you can use the MIG tools to query a local agent, as such:

mig@5345268590c8:~$ /go/bin/mig file -t all -path /usr/bin -sha2 5c1956eba492b2c3fffd8d3e43324b5c477c22727385be226119f7ffc24aad3f

1 agent has found results

To explore the capabilities of MIG, take a look at the CheatSheet.

What is this?

MIG is composed of agents installed on all systems of an infrastructure that are be queried in real-time to investigate the file-systems, network state, memory or configuration of endpoints.

Capability Linux MacOS Windows
file inspection check check check
network inspection check check (partial)
memory inspection check check check
vuln management check (planned) (planned)
log analysis (planned) (planned) (planned)
system auditing check (planned) (planned)

Imagine it is 7am on a saturday morning, and someone just released a critical vulnerability for your favorite PHP application. The vuln is already exploited and security groups are releasing indicators of compromise (IOCs). Your weekend isn't starting great, and the thought of manually inspecting thousands of systems isn't making it any better.

MIG can help. The signature of the vulnerable PHP app (the md5 of a file, a regex, or just a filename) can be searched for across all your systems using the file module. Similarly, IOCs such as specific log entries, backdoor files with md5 and sha1/2/3 hashes, IP addresses from botnets or byte strings in processes memories can be investigated using MIG. Suddenly, your weekend is looking a lot better. And with just a few commands, thousands of systems will be remotely investigated to verify that you're not at risk.

MIG command line demo

MIG agents are designed to be lightweight, secure, and easy to deploy so you can ask your favorite sysadmins to add it to a base deployment without fear of breaking the entire production network. All parameters are built into the agent at compile time, including the list and ACLs of authorized investigators. Security is enforced using PGP keys, and even if MIG's servers are compromised, as long as our keys are safe on your investigator's laptop, no one will break into the agents.

MIG is designed to be fast, and asynchronous. It uses AMQP to distribute actions to endpoints, and relies on Go channels to prevent components from blocking. Running actions and commands are stored in a Postgresql database and on disk cache, such that the reliability of the platform doesn't depend on long-running processes.

Speed is a strong requirement. Most actions will only take a few hundreds milliseconds to run on agents. Larger ones, for example when looking for a hash in a big directory, should run in less than a minute or two. All in all, an investigation usually completes in between 10 and 300 seconds.

Privacy and security are paramount. Agents never send raw data back to the platform, but only reply to questions instead. All actions are signed by GPG keys that are not stored in the platform, thus preventing a compromise from taking over the entire infrastructure.

Technology

MIG is built in Go and uses a REST API that receives signed JSON messages distributed to agents via RabbitMQ and stored in a Postgres database.

It is:

  • Massively Distributed means Fast.
  • Simple to deploy and Cross-Platform.
  • Secured using OpenPGP.
  • Respectful of privacy by never retrieving raw data from endpoints.

	Signatures []string  `json:"signatures"`        // Signatures applied to the record
}

ManifestRecord describes a manifest record stored within the MIG database

func (*ManifestRecord) ContentFromFile

func (m *ManifestRecord) ContentFromFile(path string) (err error)

ContentFromFile loads manifest content from a file on the file system (a gzip'd tar file), primarily utilized by mig-console during manifest creation operations

func (*ManifestRecord) FileFromContent

func (m *ManifestRecord) FileFromContent(path string) (err error)

FileFromContent writes manifest content to a file on the file system

func (*ManifestRecord) ManifestObject

func (m *ManifestRecord) ManifestObject(obj string) ([]byte, error)

ManifestObject returns the requested file object as a gzip compressed byte slice from the manifest record

func (*ManifestRecord) ManifestResponse

func (m *ManifestRecord) ManifestResponse() (ManifestResponse, error)

ManifestResponse converts a manifest record into a manifest response

func (*ManifestRecord) Sign

func (m *ManifestRecord) Sign(keyid string, secring io.Reader) (sig string, err error)

Sign will sign a manifest record using the indicated key ID

func (*ManifestRecord) Validate

func (m *ManifestRecord) Validate() (err error)

Validate validates an existing manifest record

type ManifestResponse

type ManifestResponse struct {
	LoaderName string          `json:"loader_name"`
	Entries    []ManifestEntry `json:"entries"`
	Signatures []string        `json:"signatures"`
}

ManifestResponse is the response to a standard manifest request

func (*ManifestResponse) Validate

func (m *ManifestResponse) Validate() error

Validate validates a ManifestResponse type ensuring required content is present

func (*ManifestResponse) VerifySignatures

func (m *ManifestResponse) VerifySignatures(keyring io.Reader) (validcnt int, err error)

VerifySignatures verifies the signatures present in a manifest response against the keys present in keyring. It returns the number of valid unique signatures identified in the ManifestResponse.

type Operation

type Operation struct {
	Module     string      `json:"module"`
	Parameters interface{} `json:"parameters"`

	// If WantCompressed is set in the operation, the parameters
	// will be compressed in PostAction() when the client sends the
	// action to the API. This will also result in IsCompressed being
	// marked as true, so the receiving agent knows it must decompress
	// the parameter data.
	IsCompressed   bool `json:"is_compressed,omitempty"`
	WantCompressed bool `json:"want_compressed,omitempty"`
}

Operation is an object that maps to an agent module. The parameters of the operation are passed to the module as an argument, and thus their format depends on the module itself.

func (*Operation) CompressOperationParam

func (op *Operation) CompressOperationParam() (err error)

CompressOperationParam compresses the parameters stored within an operation

func (*Operation) DecompressOperationParam

func (op *Operation) DecompressOperationParam() (err error)

DecompressOperationParam decompresses the parameters stored within an operation

type RunnerResult

type RunnerResult struct {
	Action     Action    `json:"action"`
	Commands   []Command `json:"commands"`
	EntityName string    `json:"name"`
	UsePlugin  string    `json:"plugin"`
}

RunnerResult describes results that are produced by mig-runner. This data would be consumed by mig-runner plugins.

type Threat

type Threat struct {
	Ref    string `json:"ref,omitempty"`
	Level  string `json:"level,omitempty"`
	Family string `json:"family,omitempty"`
	Type   string `json:"type,omitempty"`
}

Threat provides the investigator with details on a threat indicator if included in an action
