Finding the malicious needle in your endpoint haystacks

Accelerate Threat Hunts and Investigations with Pre-Curated Complex Queries

Security teams often lack the ability to gain deep visibility into the state of all their endpoints in real time. Even with a bevy of tools at their fingertips, once an incident occurs, conducting investigations can be likened to searching for a needle in a haystack. Teams struggle to make well informed remediation decisions fast enough, finding themselves asking questions like, what should I be searching for? Where specifically in my environment should I zero-in? Which datasets matter? Which are irrelevant? The struggle is real. As we all know, the longer a threat runs wild, the more havoc it stands to wreak on your environment. Between the intense time-pressure, endless datasets to sift through, and ambiguity associated with not knowing where or how to start, incident investigations can feel like frenzied wild goose chases.

Many teams have adopted threat hunting to take a more proactive and preventative (rather than purely reactive) approach to managing their security hygiene. With 43% of organizations performing continuous threat hunting operations in 2018, versus just 35% in 2017, the practice is undoubtedly growing in scope and popularity. However, this begs the question: what’s holding back the remaining majority – the other 57% – of organizations? The reality is that although many teams want to threat hunt, they simply don’t know how to get started, or erroneously believe that they don’t have the personnel, time, and resources to dedicate to the endeavor. But fortunately, that’s no longer the case…

Know everything. About every endpoint. Right now.

Cisco recently rolled out a powerful new advanced threat hunting and investigation capability in Cisco® AdvancedMalware Protection (AMP) for Endpoints called Orbital Advanced Search that gives users the ability to search across all endpoints for forensic information and malware artifacts. Think of this as the ultimate search engine for all your endpoints – with over a hundred pre-canned queries provided, Orbital makes security investigations and threat hunting simple by allowing you to quickly run complex queries on hundreds of attributes in near real-time on any or all endpoints. For example, it allows you to type in queries like:

• Show me all computers that are listening on certain ports – something that certain variants of malware will do when they are waiting on instructions from a C&C on what to do.
• Show me all processes that are running in memory but do not have a file on disk – something that is rarely seen with innocuous processes, and thus strongly indicates the possible presence of fileless malware trying to escape scanning and analysis hiding out in your environment.
• Show me all the users logged in – if a user is logged into systems in a department that the user doesn’t belong in, or if the user is logged into multiple machines at one time, this could indicate a breach.

Orbital gives you deep visibility into what’s happening on any endpoint at any time by taking a snapshot of its current state, and the search options are limitless; users can immediately perform advanced searches via the 100+ curated queries that come with the tool or create their own custom queries. Whether you’re threat hunting, conducting an incident investigation, IT operations, or vulnerability and compliance assessments, Orbital gets you the answers you need about your endpoints fast.

 

How does it work?

Whether you are investigating an incident or proactively hunting for threats Orbital can help you simplify and accelerate these tedious processes in the following ways:

1. Forensics snapshots. We can capture snapshots of data from endpoints such as running processes, open network ports and a lot more at the time of detection or on demand. It’s like “freeze framing” activity on an endpoint right to the moment. This allows you to know exactly what was happening on your endpoint at that point in time.
2. Live search. Run complex queries on your endpoints for threat indicators on demand or on a schedule, capturing the information you need about your endpoints in near real time.
3. Predefined and customizable queries. We provide over a hundred predefined queries that you can quickly run as they are or customize them as needed. These queries are simply organized in a catalog of common use cases and mapped to the MITRE ATT&CK.
4. Storage options. The results of your queries can be stored in the cloud or sent to other applications such as Cisco Threat Response for further or future investigations.

 

Common use cases

Orbital Advanced Search can help you do the following important tasks better, faster:

1. Advanced Threat Hunting: Search for malicious artifacts across any or all your endpoints in near real-time to accelerate threat hunts.
   1. Mature organizations – Streamline workflows for seasoned teams that already perform continuous threat hunting operations and get beyond atomic and computed IOCs and into the really interesting stuff, like registry keys, process PID exploits, and all kinds of attacker TTPs cataloged with Threat Grid and the MITRE ATT&CK.
   2. Novice Threat Hunters – Empowers teams that don’t have threat hunting programs in place to begin to threat hunt without requiring them to hire additional staff or rip and replace their security stack.
2. Incident Investigation: Get to the root cause of incidents faster to accelerate incident investigation and remediation efforts.
3. IT Operations: Track software inventory, disk space, memory, computer utilization, and other IT operations artifacts quickly and expediently – good threat hunting tools can also be used to enhance IT operations.
4. Vulnerability and Compliance: Easily check the status of Operating Systems for things like software version levels to validate patch management to ensure that your endpoints are in compliance with current policies.

Threat Hunting Versus Incident Response

An additional bonus to threat hunting is that it breeds familiarity with tools and techniques that come into play when an incident or breach does occur, effectively training teams to be better incident responders. Since both disciplines deal directly with threats in your environment, the skills exercised when threat hunting are arguably one and the same as those associated with incident response. The only difference is that whereas incident response is reactive and involves known evidence of a threat in your environment, threat hunting is a proactive practice that is carried out without evidence. Since practicing threat hunting sharpens investigative skills and response times, teams that threat hunt are naturally better equipped to react like pros when faced with real incidents. The ‘Hunting for hidden threats’ whitepaper in Cisco’s Cybersecurity Report Series covers this topic in more detail and is a great place to learn even more.

Whether you’re new to threat hunting, are a seasoned veteran who wants to streamline operations and take your threat hunting program to the next level, or merely want to accelerate incident remediation, the solution to your woes has arrived.
