Accept the installation, then wait for the process to finish. The cybersecurity firm, CrowdStrike has warned that Chinese hackers are using the Log4Shell exploit tools to perform various post-exploitation operations. The hacker group behind these malicious operations, Aquatic Panda was seen using the Log4Shell vulnerability, with the help of a large academic institution.

Aquatic Panda is a Chinese hacking group that is operating since May and it has two primary goals To gain initial access to the target system, the Aquatic Panda uses a modified version of the exploit for a bug in Log4j, and then it performs several post-exploitation activities like The hackers targeted VMware Horizon that used the vulnerable Log4j library to compromise a large academic institution, and on December 13, , the exploit used in this attack was published on GitHub.

On the Windows host where the Apache Tomcat service was running, the team ran a series of Linux commands, and not only that even they also performed the same on those aimed at deploying malicious tools that are hosted on remote infrastructure. Here at this point to better understand privilege levels and learn more about the domain, the threat actors have also conducted surveillance efforts. While they also tried to interrupt a response solution and third-party endpoint threat detection solution.

The malware and three VBS files were extracted by the hackers through PowerShell commands, and to accomplish this, additional scripts were deployed by the hackers. At this stage, by performing memory dumps and preparing them for theft, the threat actors of Aquatic Panda attempted several trials to collect credentials.

Moreover, the attacked academic institution was timely warned of suspicious activities to be able to quickly use the incident response protocol, fixing vulnerable software and deterring further development of the malicious activity. This includes a vast array of sophisticated detection and prevention technologies, a virtual sea of cyber intelligence reporting, and access to a rapidly expanding workforce of talented IT professionals.

Yet, most CSOCs continue to fall short in keeping the adversary—even the unsophisticated one—out of the enterprise. Ensuring the confidentiality, integrity, and availability of the modern information technology IT enterprise is a big job. It incorporates many tasks, from robust systems engineering and configuration management CM to effective cybersecurity or information assurance IA policy and comprehensive workforce training. It must also include cybersecurity operations, where a group of people is charged with monitoring and defending the enterprise against all measures of cyber attack.

A SOC is a team primarily composed of security analysts organized to detect, analyze, respond to, report on, and prevent cybersecurity incidents.

The practice of defense against unauthorized activity within computer networks, including monitoring, detection, analysis such as trend and pattern analysis , and response and restoration activities. There are many terms that have been used to reference a team of cybersecurity experts assembled to perform CND. SOCs can range from small, five-person operations to large, national coordination centers.

Monitoring, detection, and analysis of potential intrusions in real time and through historical trending on security-relevant data sources. Response to confirmed incidents, by coordinating resources and directing use of timely and appropriate countermeasures. Providing situational awareness and reporting on cybersecurity status, incidents, and trends in adversary behavior to appropriate organizations. Of these responsibilities, perhaps the most time-consuming are the consumption and analysis of copious amounts of security-relevant data.

Among the many security-relevant data feeds a Security Operations Center is likely to ingest, the most prominent are often IDSes. Combined with security audit logs and other data feeds, a typical SOC will collect, analyze, and store tens or hundreds of millions of security events every day.

An event is nothing more than raw data. It takes human analysis—the process of evaluating the meaning of a collection of security-relevant Fundamentals Ten Strategies of a World-Class Cybersecurity Operations Center 11 data, typically with the assistance of specialized tools—to establish whether further action is warranted.

Continuously monitors the alert queue; triages security alerts; monitors health of security sensors and endpoints; collects data and context necessary to initiate Tier 2 work. Alert triage procedures; intrusion detection; network, security information and event management SIEM and host-based investigative training; and other tool-specific training.

Performs deep-dive incident analysis by correlating data from various sources; determines if a critical system or data set has been impacted; advises on remediation; provides support for new analytic methods for detecting threats. Advanced network forensics, host-based forensics, incident response procedures, log reviews, basic malware assessment, network forensics and threat intelligence.

Advanced training on anomaly detection; tool-specific training for data aggregation and analysis and threat intelligence. Manages resources to include personnel, budget, shift scheduling and technology strategy to meet SLAs; communicates with management; serves as organizational point person for business-critical incidents; provides overall direction for the SOC and input to the overall security strategy.

Project management, incident response management training, general people management skills. The SOC typically will leverage internal and external resources in response to and recovery from the incident. It is important to recognize that a SOC may not always deploy countermeasures at the first sign of an intrusion.

There are three reasons for this:. To determine the nature of the attack, the SOC often must perform advanced forensic analysis on artifacts such as hard drive images or full-session packet capture PCAP , or malware reverse engineering on malware samples collected in support of an incident. Sometimes, forensic evidence must be collected and analyzed in a legally sound manner.

In such cases, the SOC must observe greater rigor and repeatability in its procedures than would otherwise be necessary. In addition to SOC analysts, a security operations center requires a ringmaster for its many moving parts. The SOC manager is responsible for prioritizing work and organizing resources with the ultimate goal of detecting, investigating and mitigating incidents that could impact the business. The SOC manager should develop a workflow model and implement standardized operating procedures SOPs for the incident-handling process that guides analysts through triage and response procedures.

Defining repeatable incident triage and investigation processes standardize the actions a SOC analyst takes and ensures no important tasks fall through the cracks. An enterprisewide data collection, aggregation, detection, analytic and management solution is the core technology of a successful SOC.

An effective security monitoring system incorporates data gathered from the continuous monitoring of endpoints PCs, laptops, mobile devices and servers as well as networks and log and event sources. With the benefit of network, log and endpoint data gathered prior to and during the incident, SOC analysts can immediately pivot from using the security monitoring system as a detective tool to using it as an investigative tool, reviewing suspicious activities that make up the present incident, and even as a tool to manage the response to an incident or breach.

By centralizing these various sources of data into a security monitoring system, the SOC gains actionable insight into possible anomalies indicative of threat activity. Based on findings, automated and manual interventions can be made to include patching, firewall modification, system quarantine or reimage, and credential revocation. Security operations analysts can analyze data from various sources and further interrogate and triage devices of interest to scope an incident.

A Roadmap the SOC analyst to investigate the system in question, the analyst generally needs other information, such as the owner and hostname of the machine or DHCP-sourced records for mapping IP and host information at the time of the alert. If the security monitoring system incorporates asset and identity information, it provides a huge advantage in time and analyst effort, not to mention key factors the analyst can use to prioritize the security incident—generally speaking, higher-value business assets should be prioritized over lower-value assets.

The ability to create a baseline of activity for users, applications, infrastructure, network and other systems , establishing what normal looks like, is one advantage of aggregated data collected from various enterprise sources. A properly baselined and configured security monitoring system sends out actionable alerts that can be trusted and often automatically prioritized before getting to the Tier 1 analyst.

When an unexpected behavior or deviation of normal activity is detected, the platform creates an alert, indicating further investigation is warranted.

Mature SOCs continually develop the capability to consume and leverage threat intelligence from their past incidents and from information-sharing sources, such as a specialized threat intelligence vendor, industry partners, the cybercrimes division of law enforcement, information-sharing organizations such as ISACs , or their security monitoring technology vendors.

When choosing an enterprise security monitoring tool, look for such features as alert threshold customization and the ability to combine many alerts into a single incident. Also when incidents include additional context, analysts can triage them more quickly, reducing the layers of evaluation that must take place before an issue can be confirmed and quickly mitigated. Categorize SOCs that are internal to the constituency into five organizational models of how the team is comprised,.

No standing incident detection or response capability exists. In the event of a computer security incident, resources are gathered usually from within the constituency to deal with the problem, reconstitute systems, and then 16 stands down.

Results can vary widely as there is no central watch or consistent pool of expertise, and processes for incident handling are usually poorly defined. Constituencies composed of fewer than 1, users or IPs usually fall into this category. With an intuitive and simple graphical user interface, it is easy to handle even for a green hand in computer.
