Scattered Spider's technical tactics: social engineering, cloud exploits, ransom...
Scattered Spider has emerged as one of the most sophisticated and dangerous cybercriminal groups in recent years. This English-speaking threat actor has gained notoriety for its exceptional social engineering skills and high-profile attacks, including the 2023 MGM Resorts breach that caused widespread system shutdowns and the recent 2025 attacks on major UK retailers.
What makes Scattered Spider particularly concerning is its rapid evolution from SIM swapping and credential theft to full-scale ransomware operations, its partnership with established ransomware groups, and its predominantly Western membership-a rarity in the cybercriminal ecosystem. This report provides a comprehensive analysis of Scattered Spider's origins, techniques, notable attacks, and mitigation strategies based on the latest intelligence.
## Origins and Organisational Structure
Scattered Spider (also tracked as UNC3944, Starfraud, Scatter Swine, Muddled Libra, and Octo Tempest) emerged in early 2022 and has since evolved into a sophisticated threat actor targeting organizations across multiple sectors. Unlike traditional cybercriminal groups that operate from Eastern Europe or Asia, Scattered Spider comprises predominantly young, English-speaking individuals believed to be based in the United States and United Kingdom.
The group operates as a decentralized collective rather than a hierarchical organization, with members as young as 16-22 years old who coordinate primarily through messaging platforms like Telegram and Discord. This loose-knit structure has proven remarkably resilient against law enforcement disruption efforts, as demonstrated by their continued operations despite several arrests.
## How does Scattered Spider's use of Social Engineering techniques differ from other Cybercriminal groups
Scattered Spider is considered part of a larger hacking community known as "The Community" or "The Comm," whose members have targeted major technology companies and financial institutions. What distinguishes Scattered Spider from other threat actors is their native English language skills and deep understanding of Western corporate culture, which significantly enhances their social engineering capabilities.
### Organizational Evolution
When first observed in May 2022, Scattered Spider focused primarily on telecommunications companies and business process outsourcing (BPO) firms, conducting SIM swapping attacks and credential theft. By mid-2023, they had expanded both their targeting scope and technical capabilities, engaging in data theft for extortion and partnering with established ransomware operations.
This evolution has continued through 2024-2025, with the group regularly shifting between ransomware platforms-including BlackCat/ALPHV, Ransom.Hub, Qilin, and most recently DragonForce-while maintaining their core social engineering expertise[6][10]. This affiliate model allows them to "rent" ransomware from larger criminal organizations while sharing profits from successful attacks.
## Technical Capabilities and Attack Methodology
Scattered Spider employs a sophisticated and multi-layered attack methodology that combines exceptional social engineering skills with technical capabilities to breach target networks, establish persistence, and ultimately deploy ransomware or exfiltrate sensitive data.
### Initial Access Techniques
The group's initial access strategies are centered around social engineering, with particular emphasis on exploiting human trust relationships rather than technical vulnerabilities:
1. **Helpdesk and IT Support Impersonation**: Scattered Spider members call company helpdesks posing as employees requiring assistance, often claiming they need password resets or MFA configuration for new devices.
2. **SIM Swapping**: The group convinces mobile carriers to transfer control of targeted users' phone numbers to attacker-controlled SIM cards, enabling them to intercept multi-factor authentication codes.
3. **MFA Fatigue/Push Bombing**: Victims are bombarded with MFA notifications until they approve access out of frustration or confusion.
4. **Phishing Campaigns**: Scattered Spider deploys sophisticated phishing emails, SMS messages, and even voice calls (vishing) that impersonate legitimate corporate communications.
5. **New Employee Impersonation**: Group members blend into onboarding processes by posing as new hires to gain initial access and appear legitimate.
6. **Domain Spoofing**: The group creates convincing fake domains that mimic corporate resources (e.g., victimname-sso[.]com, victimname-servicedesk[.]com).
What makes these techniques particularly effective is the group's extensive reconnaissance and preparation. Before initiating contact, they acquire significant personal information about potential victims-including last four digits of Social Security numbers, birth dates, managers' names, and job titles-which helps them bypass identity verification processes.
### Post-Compromise Activities
Once inside a target environment, Scattered Spider demonstrates sophisticated post-exploitation capabilities:
1. **Reconnaissance**: The group conducts thorough internal reconnaissance of Microsoft applications, Active Directory, SharePoint sites, and cloud infrastructure to identify valuable resources and potential lateral movement paths.
2. **Legitimate Tool Deployment**: Rather than using custom malware that might trigger security alerts, Scattered Spider leverages legitimate remote access tools like ScreenConnect, TeamViewer, Splashtop, and remote monitoring tools such as Fleetdeck.io and Level.io.
3. **Privilege Escalation**: They use tools like Mimikatz for credential harvesting and exploit permission models to gain administrator access.
4. **Cloud Infrastructure Abuse**: Scattered Spider demonstrates deep knowledge of Microsoft Azure environments and built-in tools, using cloud permissions to create persistent access.
5. **Virtual Machine Creation**: The group creates new virtual machines within compromised environments from which they conduct further malicious activities, often reconfiguring these systems to deactivate security controls.
6. **Security Tool Evasion**: They systematically compromise security accounts to disable or impair security products, evading detection while establishing persistence.
### Data Exfiltration and Encryption
In the final stages of their attacks, Scattered Spider employs sophisticated data theft and encryption techniques:
1. **Data Targeting**: They specifically search for sensitive customer information, intellectual property, and financial data that can be used for extortion.
2. **Exfiltration Methods**: The group exfiltrates data to various destinations including U.S.-based data centers, MEGA.nz, and high-reputation cloud services like Google Cloud Platform and Amazon Web Services.
3. **Double Extortion**: Since mid-2023, Scattered Spider has employed a double extortion model-first stealing sensitive data and then encrypting systems to maximize leverage over victims.
4. **Ransomware Deployment**: Through their partnerships with ransomware groups, they deploy various ransomware strains including BlackCat/ALPHV on Microsoft and Linux systems, and most recently DragonForce ransomware as seen in the M&S attack.
## High-Profile Attack Cases
Scattered Spider has been linked to several significant cyberattacks that have caused substantial financial damage and operational disruption to major organizations worldwide.
### Casino and Hospitality Industry Attacks (2023)
In September 2023, Scattered Spider orchestrated one of their most high-profile attacks against MGM Resorts International and Caesars Entertainment, two of the largest casino and gambling companies in the United States.
The MGM attack began with a social engineering attack targeting the IT helpdesk. A Scattered Spider operator impersonated an employee in a phone call, convincing helpdesk staff to reset credentials, which ultimately allowed them to access the network. The breach forced MGM to shut down systems across all 31 of its resorts, resulting in widespread disruption to hotel check-ins, casino operations, and digital services.
Concurrently, Caesars Entertainment was also compromised, leading to the theft of sensitive customer data reportedly impacting over 65 million loyalty program members. Under pressure, Caesars reportedly paid $15 million in ransom to prevent the release of stolen data.
These casino attacks demonstrated Scattered Spider's progression to targeting larger enterprises with more sophisticated attack chains, causing significant financial and reputational damage.
### Twilio and Okta Supply Chain Attack (2022)
In 2022, Scattered Spider conducted a significant breach of the communications platform Twilio, which then led to compromises of multiple Okta customers through a supply chain attack vector. This campaign revealed the group's understanding of identity and access management systems and their ability to leverage initial access to one service provider to compromise downstream customers.
The attack chain involved obtaining [Okta identity credentials](https://www.secureblink.com/cyber-security-news/okta-support-system-data-breach-exposes-cookies-and-tokens) and MFA codes to execute supply chain attacks against Okta's clients. This incident highlighted how Scattered Spider could exploit trust relationships between service providers and their customers.
### UK Retail Sector Attacks (2025)
In April 2025, Scattered Spider launched a series of attacks against major UK retailers, beginning with Marks & Spencer (M&S). The attack severely disrupted M&S operations, leaving stores with empty shelves and forcing the company to pause its online shopping services. This attack wiped over £700 million from M&S's stock market valuation.
According to reports, the attackers gained access to M&S systems through Active Directory, deploying DragonForce ransomware after establishing persistence. Following the M&S breach, both Co-op and Harrods reported cyber incidents and restricted access to internal systems on April 30 and May 1, 2025, respectively.
These recent retail sector attacks demonstrate Scattered Spider's continued evolution and expansion of its targeting, moving beyond its previous focus on the telecommunications, hospitality, and gaming industries.
## What role does ALPHV play in Scattered Spider's operations
ALPHV (also known as BlackCat) played a pivotal role in Scattered Spider's operations by serving as the primary ransomware provider through a Ransomware-as-a-Service (RaaS) model. In this arrangement, Scattered Spider acted as an affiliate: they specialized in gaining initial access to target organizations-primarily through advanced social engineering and credential theft-and then leveraged ALPHV's ransomware platform to execute the actual encryption and extortion phases of their attacks[2][3][4].
This partnership was particularly evident in high-profile incidents such as the 2023 attacks on MGM Resorts and Caesars Entertainment, where Scattered Spider breached the organizations and then deployed ALPHV ransomware to lock systems and extort payments. In these cases, Scattered Spider was responsible for the initial compromise and lateral movement, while ALPHV provided the ransomware payload, infrastructure, and leak sites for publishing stolen data[2][4].
ALPHV's RaaS model enabled Scattered Spider to:
- Deploy highly customizable ransomware variants that could target both Windows and Linux environments.
- Use ALPHV's dedicated leak sites to pressure victims through public data exposure.
- Benefit from ALPHV's advanced encryption and evasion techniques, amplifying the impact and success rate of their attacks[.
This collaboration allowed both groups to specialise: Scattered Spider focused on initial access and social engineering, while ALPHV handled ransomware development, payment negotiations, and data leak infrastructure. The relationship was mutually beneficial until ALPHV's operations were disrupted by law enforcement in late 2023 and early 2024, after which Scattered Spider began affiliating with other ransomware providers.
### Gaming Industry Targeting
Scattered Spider also targeted Riot Games, creators of popular games like League of Legends. During this attack, they stole source code for League of Legends and Teamfight Tactics, demanding a $10 million ransom payment. This incident showcased their ability to identify and exfiltrate high-value intellectual property.
## Ransomware Partnerships and Affiliations
One of Scattered Spider's distinctive characteristics is their strategic partnerships with established ransomware operations, allowing them to leverage existing ransomware infrastructure while contributing their exceptional social engineering skills.
### ALPHV/BlackCat Collaboration
Scattered Spider's most documented collaboration has been with the ALPHV/BlackCat ransomware group, one of Russia's most prolific cybercriminal organisations. This partnership represents an unusual alliance between English-speaking and Russian threat actors, with ALPHV providing the ransomware infrastructure while Scattered Spider delivers initial access through their social engineering expertise.
This collaboration was evident in the September 2023 MGM Resorts attack, where BlackCat ransomware was deployed after initial access was achieved through Scattered Spider's social engineering tactics. The relationship demonstrates how specialized skills within the cybercriminal ecosystem can be combined for more effective attacks.
### Evolution of Ransomware Partnerships
Since early 2023, Scattered Spider has demonstrated flexibility in their ransomware partnerships, working with multiple Ransomware-as-a-Service (RaaS) operations:
1. **BlackCat/ALPHV**: Their initial ransomware partner, used in several high-profile attacks.
2. **RansomHub**: A relatively newer ransomware operation that Scattered Spider has affiliated with.
3. **Qilin**: Another ransomware variant used by the group in their extortion campaigns.
4. **DragonForce**: Their most recent affiliation, reportedly used in the 2025 Marks & Spencer attack.
This affiliate model allows Scattered Spider to "rent" or white-label ransomware from larger gangs in exchange for a share of the profits, while focusing on their core competency of gaining initial access. The group's willingness to switch between different ransomware platforms demonstrates their adaptability and business-oriented approach to cybercrime.
## Law Enforcement Response
Despite the group's continued operations, law enforcement agencies have made some progress in identifying and apprehending suspected members of the Scattered Spider.
### Arrests and Indictments
