What You Will Learn
Learning to thwart the threat of human-operated ransomware once and for all!

The term "Ransomware" no longer refers to a simple encryptor that locks down resources. The advent of Human-Operated Ransomware (HumOR) along with the evolution of Ransomware-as-a-Service (RaaS) have created an entire ecosystem that thrives on hands-on the keyboard, well-planned attack campaigns. It is a rapidly growing threat that has evolved from being a single machine infection following an ill-advised mouse click to becoming a booming enterprise capable of crippling large and small networks alike. Even when extortion actors do not deploy an encryptor, the fallout can be devastating.

Organizations are at risk of losing their data and information to these attacks, which can lead to revenue losses, reputational damage, theft of employee time and productivity, and inability to function normally. It is now common to see these large-scale, sophisticated attacks where the ransomware actors first establish persistence and execute tools on their target, then move laterally throughout the organization, and ultimately exfiltrate data before deploying their ransomware payloads. That is, if they even deploy an encryptor.

Even though payments to ransomware actors slowed in early 2022 as compared to previous years, that same year there were over 2,600 posts made to extortion sites related to ransomware. This number does not include an unknown quantity of incidents that were resolved through communication and/or negotiation behind the scenes prior to public notification. Of the reported incidents from 2022, the following are the top 10 compromised sectors:
  • Construction
  • Hospital and Health Care
  • Government Administration
  • IT Services and IT Consulting
  • Law Practice
  • Automotive
  • Financial Services
  • Higher Education
  • Insurance
  • Real Estate
The FOR528: Ransomware and Cyber Extortion course teaches students how to deal with the specifics of ransomware to prepare for, detect, hunt, respond to, and address the aftermath of these attacks. The course features a hands-on approach to learning using real-world data and includes a full day capture the flag (CTF) challenge to help students solidify their learning. The four-day class teaches students what artifacts to collect, how to collect them, how to scale collection efforts, how to parse the data, and how to review the parsed results in aggregate.

The course also provides in-depth details and detection methods for each phase of the ransomware and cyber extortion attack lifecycle. These phases include Initial Access, Execution, Defense Evasion, Persistence, Attacks on Active Directory (AD), Privilege Escalation, Credential Access, Lateral Movement, Data Access, Data Exfiltration, and Payload Deployment.

Unfortunately, many businesses will find themselves falling victims to ransomware attacks because they feel they are not in danger. Regardless of whether your organization is small, medium, or large, every internet-connected network is at risk... and the threat is not going away any time soon.

What Is Ransomware and Cyber Extortion?

While ransomware incidents involve entry into an environment usually with the goals of exfiltrating data and then encrypting resources, cyber extortion groups perform the same types of attacks, yet do not encrypt the environment. In essence, an incident following common ransomware TTPs/IOCs that does not involve encryption is often referred to simply as cyber extortion.
Business Takeaways
  • Bolster defenses by implementing preventative measures to stop ransomware actors from gaining access to your organization
  • Quickly detect when a ransomware actor has gained access to your environment and is leveraging tools common to the trade
  • Identify what ransomware attacks look like to help work out a plan for responding if it's detected on the network
  • Respond quickly through understanding where to focus your efforts given your unique environment
  • Identify which backups to use for restoration to ensure successful restoration while avoiding restoring threat access persistence within your environment.
  • Determine if an identified actor within your environment is affiliated with ransomware.
  • Identify what data may have been accessed, how, and when
  • Identify what data may have been exfiltrated by a ransomware actor (This course prepares you for the [GWEB] certification that meets the requirements of the DoD8140 IAT Level 2)
