Cloud breaches proceed to rise unabated as organizations undertake hybrid cloud methods. Many organizations have tried to easily lengthen their preexisting on-premises safety into the cloud, however the cloud is a basically totally different setting for safety. It’s quicker, extra advanced, and extra dynamic, with an ever-increasing assault floor. Placing first means adversaries have a head begin by default, leaving organizations solely a fraction of time to analyze and provoke a response.
With all this in thoughts, it’s no shock that in line with Forrester analysis, “cloud detection and response is the next and most important frontier for security operations teams.”1 To reply this want, Sysdig’s real-time cloud investigation provides organizations again treasured time, reduces talent gaps, and grants safety and platform groups the flexibility to make quicker, better-informed choices.
Sysdig’s new investigation capabilities allow clients to optimize their cloud detection and response (CDR) use circumstances with automated assortment and correlation of all their cloud knowledge, together with occasions, posture misconfigurations, and exploitable vulnerabilities to identities.
The improved consumer interface permits safety groups to work together with and immediately decipher essentially the most advanced assault chains, unlocking your capacity to analyze threats in below 5 minutes, as outlined within the 555 Benchmark.
The important thing new capabilities enriching your investigations embody:
- Assault chain visualization – Leverage any alert or suspicious findings as the basis trigger to launch an investigation with the Sysdig Cloud Assault Graph.
- Actual-time id correlation – Enhanced investigation capabilities routinely correlate cloud occasions with id knowledge.
- Investigation workflow optimization – A single purpose-built platform breaks silos and streamlines downstream actions for safety personas with numerous talent units.

Sysdig’s new investigation stream routinely stitches collectively context from throughout the Sysdig platform. It quickly identifies the basis explanation for occasions and contextualizes knowledge to hurry up investigations within the cloud.
To show the facility of Sysdig’s new investigation capabilities, we simulated a SCARLETEEL assault that exploits a susceptible software in a containerized workload. This contains steps to ascertain a reverse shell, obtain a cryptominer, elevate privileges to disable S3 bucket insurance policies, and steal buyer knowledge.
We start our investigation with the Occasions Overview dashboard. Safety groups could monitor a similar-looking dashboard throughout your multi-cloud setting.
If we set the time-frame to 6 hours utilizing the time picker beneath, we discover a sudden spike within the quantity of high-severity occasions (see Occasions By Severity widget) inside this quick timeframe. That is uncommon; on most days you don’t see this many occasions, and since you have to assume any uncommon exercise may point out a breach, this aberration is suspicious and warrants a immediate response. Our aim is to triage and gather as a lot info as attainable to create a deep contextual narrative.
First, let’s dive in and have a look at the occasions to uncover solutions that specify this uncommon spike seen on our dashboard. Filter for high-severity occasions to shortly intercept any ongoing assaults launched by the menace actors.
We’re redirected to the Occasions feed, the place all cloud occasions are logged and enriched with particulars, together with the triggered Sysdig guidelines/insurance policies, timestamps, account IDs, cluster names, consumer names, and the IP deal with.
This permits us to visualise the timeline of occasions main as much as a cloud assault. It additionally eliminates the talent hole, permitting analysts to simply confirm the severity of an assault, the impacted cloud workloads, and the compromised consumer accounts. The search bar on the prime and the filters on the left slim your scope of occasions to analyze, thereby enhancing your inside metrics, corresponding to SLAs (service-level agreements), MTTI (imply time to analyze), and MTTR (imply time to reply).
Sysdig’s Risk Analysis Crew additionally curates and maintains an exhaustive library of guidelines you should use, corresponding to the next instance:
ruleName = Netcat Distant Code Execution in ContainerCode language: Perl (perl)To filter related occasions inside the outlined timeframe (six hours in our demo), we’d merely sort the above string within the Search bar. Alternatively, you possibly can additionally use the left panel to derive comparable outcomes. This helps cut back noise, and scopes out related occasions that would clarify the bizarre spike detected earlier.
On this situation, we filter occasions the place Sysdig has detected a Netcat execution in your cloud workload. Netcat is a typical software utilized by adversaries to help in unlawful actions, and is flagged and quarantined by many antivirus functions. Let’s dive in and overview the components that triggered the above Sysdig rule, together with the captured command line, course of tree, consumer and cloud particulars, vulnerabilities, and the rule tags.
Sysdig offers you adequate context to collaborate with numerous personas, corresponding to vulnerability administration, builders, safety architects, infrastructure, and extra, so you possibly can interact with and deal with any safety gaps with scientific precision.
By now, your curiosity has possible been piqued sufficient to wish to uncover the relationships between the impacted sources and the contributing occasions.
Our assault chain visualization offers a single graphical overview of the adversary’s ways, methods, and procedures. It consolidates knowledge from a number of sources — together with posture misconfigurations, present vulnerabilities, launched processes, and exercise audits — to guage the affect of the continued menace.
Sysdig correlates occasions and enriches them with deep runtime insights, enabling analysts to quickly examine and pivot throughout any useful resource, occasion, or attribute. Our platform helps hint adversary actions throughout your cloud setting, and probably stop them from additional compromising your community.
At a look, you’ll achieve crucial understanding of an occasion’s context, corresponding to:
- What was the basis explanation for the occasion?
- What different techniques has the menace actor accessed which may be in danger?
- What processes and instructions have been run on the impacted workloads?
- What vulnerabilities or misconfigured permissions are in use?
- What permissions and identities have been elevated?
The runtime detections (seen to the left) depict a timeline of actions inside the specified cluster. They’re color-coded to point severities.
The graph additionally lets you immediately work together with the impacted belongings. For instance, in our demo, the workload legacy-webapp is the impacted useful resource. If we have been to click on on it, a listing of interactive choices allow you to navigate and overview the precise components that led to this high-severity occasion.
A drawer opens as much as the proper that gives under-the-hood configuration particulars of the workload, together with the picture, cluster identify, namespace, and zones. It additionally collects knowledge throughout the posture misconfigurations, in-use exploits, exercise audit, and launched processes. For instance, for those who have been to navigate to the Posture tab, you’ll observe all of the posture findings on the workload (agentless method), and the the reason why sure controls failed on the impacted workload.
This degree of context and guided remediation helps get rid of friction factors, and permits your safety groups to make split-second choices at crunch time.
Now that we’re snug dealing with the UI, let’s pivot to Processes, the place all of the executed instructions on the workload are logged at runtime. This lets you perceive whether or not this was a lone occasion or a part of a much bigger menace exercise.
From this view, you possibly can see that the consumer (assuming root privileges) downloaded a number of java information on the workload. You’ve gotten intel by now from the Vulnerabilities tab that your legacy-webapp has a Spring4Shell Java vulnerability (learn right here for extra context).
Bounce in to overview the Course of Tree for the curl command and hint the adversary motion inside your cloud property.
The method tree traces out the timeline of executed command traces captured by the agent at runtime. It illustrates the kill chain from consumer to course of, together with course of lineage, container and host info, malicious consumer particulars, and affect. Virtually instantly, you’ll see an xmrig, which is a cryptominer, weaponized as a trojan that masquerades as a reliable program however conceals malicious or undesirable performance. This xmrig was executed a number of seconds after the Java information have been downloaded on the workload. That is proof sufficient that the workload is contaminated, and it is advisable to reply promptly to include the assault.
Now that you’ve an thought of the what and the why, let’s dig deeper to uncover the who behind these occasions. The Identification view expands your investigation to find whether or not our adversary compromised any reliable consumer accounts to execute their aims.
Right here, the consumer interface shows the impacted consumer accounts, correlated at runtime with the high-severity occasions noticed in the beginning of our investigation. The adjoining world map illustrates the captured areas the place these accounts could have launched the SCARLETEEL assault. Since time is of essence right here, let’s slim our investigation window to an hour to verify the menace actor lurking in your community.
Virtually instantly, Sysdig filters an EC2 function and a consumer account Admin6 inside this time window. It additionally brings forth related occasions related to the identities on the left.
The occasions proven point out a number of reconnaissance actions inside your cloud setting. Until there’s a scheduled upkeep exercise, you normally shouldn’t see these discovery occasions throughout your cloud accounts.
After additional investigation, the info reveals that the adversary assumed the EC2 function to create entry keys for a consumer account, Admin6, inside your setting.
Admin6 doesn’t conform to regular naming requirements, and the info signifies that this explicit account has elevated privileges and several other unused permissions.
Our speculation is now confirmed, and we all know for sure that this consumer account has been taken over by the adversary. Now you can take fast corrective steps and optimize your IAM insurance policies to forestall additional adversary motion.
Increase the time window to overview all of the interactive instructions, established connections, file actions, and executable requests associated to Admin6.
Sysdig’s deep runtime insights, coupled with automated cross-cloud context and correlation, allow safety and improvement groups to know the who, what, the place, when, and why of the cloud investigation in simply 5 minutes.
This function is purpose-built to alleviate your investigation ache factors, and units you as much as obtain the 555 Benchmark quicker than with any conventional detection and response instruments.
Be part of our upcoming deminar 5-Minute Cloud Security Investigations in Motion, a technical demonstration of how Sysdig accelerates cloud-native investigation.
