Validating Cyber Defenses Against SCATTERED SPIDER with Cymulate

Advanced Persistent Threat (APT) groups continue to evolve in sophistication, and one of the most prominent examples in recent years is SCATTERED SPIDER.  

Known for their attack on Caesars Entertainment and MGM Resorts International, this group has targeted major enterprises. It is reported Caesars Entertainment paid a hefty $15 million ransom to regain control, while MGM Resorts took a different route and partnered with law enforcement to tackle the threat head-on.  

Defending against such a capable adversary requires more than just layered security — it demands continuous validation of security controls.  

This is where the Cymulate Exposure Validation Platform becomes a game-changer. Organizations can automate production-safe breach and attack simulations for offensive testing to validate their security controls using the latest threat tactics and real-world attack techniques, including those used by SCATTERED SPIDER. 

Who is SCATTERED SPIDER? 

SCATTERED SPIDER (also tracked as Roasted 0ktapus, Octo Tempest and Storm-0875 by various security vendors) is a prolific eCrime group who has conducted a range of financially motivated activity since early 2022. The group has been associated with over 100 targeted attacks across various industries, including telecommunications, finance, retail and gaming. 

How SCATTERED SPIDER Operates

SCATTERED SPIDER specializes in: 

• SIM swapping and MFA bypass 
• Active Directory abuse 
• Use of remote access tools like AnyDesk and TeamViewer 
• Credential harvesting and lateral movement 
• Deploying ransomware and data exfiltration 

Their tactics overlap with both cybercrime and nation-state-level techniques, making them a hybrid threat that requires nuanced detection and tailored defensive strategies. 

Scattered Spider frequently gains access by manipulating people rather than just exploiting software weaknesses. For instance, previous incidents involved "social engineering attacks" where they tricked individuals into resetting employee passwords, which then allowed them to infiltrate the network.  

Beyond mimicking official company emails to steal employee information, they also employ "SIM swapping" – cloning an employee's phone number to request password resets from the IT help desk – and create fake login pages that closely resemble legitimate corporate portals. 

How Cymulate Helps Validate Cyber Defenses Against SCATTERED SPIDER 

1. Simulate SCATTERED SPIDER TTPs 

Cymulate offers pre-built attack scenarios and custom threat simulations based on MITRE ATT&CK techniques commonly used by SCATTERED SPIDER. This includes: 

• Credential dumping (e.g., Mimikatz usage) 
• Lateral movement with PsExec, RDP or WMI 
• Use of legitimate IT tools (LOLBins) 
• Privilege escalation and persistence via registry modifications or scheduled tasks 

You can simulate these behaviors in a safe environment to validate whether your EDR, SIEM and/or other detection tools are tuned to detect and prevent them. 

2. Phishing and Social Engineering Campaigns 

Since SCATTERED SPIDER frequently initiates attacks via phishing and vishing (voice phishing), Cymulate Email Gateway assessments and Employee Awareness simulation modules help test your workforce’s resilience: 

• Send realistic, customisable phishing emails 
• Evaluate user susceptibility and track click-through rates 
• Identify gaps in email filtering and user awareness 

3. Lateral Movement and Privilege Escalation Testing 

Using Lateral Movement and Privilege Escalation scenarios, Cymulate safely tests whether attackers could move laterally within your network — mimicking how SCATTERED SPIDER navigates environments post-compromise. 

Insights from these simulations show: 

• How well segmentation policies are enforced 
• If privilege abuse attempts are detected 
• How effectively your SOC can respond 

4. Immediate Gap Analysis and Remediation Guidance 

Cymulate doesn't just highlight gaps — it offers actionable remediation steps. After running a simulation, the platform provides: 

• Detailed risk scores 
• Configuration weaknesses 
• Specific detection rule enhancements (e.g., Sigma rules or EDR tuning suggestions) 

This accelerates your ability to harden defenses proactively. 

5. Continuous Threat Intelligence Integration 

Cymulate regularly updates its threat intelligence feeds with the latest IOCs from groups like SCATTERED SPIDER. As their tactics evolve, Cymulate ensures your simulations evolve too, enabling real-time validation against emerging threats.
