The Rise of Scattered Spider
Formed in May 2022, Scattered Spider, also known as UNC3944, has quickly gained notoriety for its sophisticated cyberattacks. The group operates with a business-like structure, assigning specific roles ranging from leadership to temporary associates, which has contributed to its effectiveness. (en.wikipedia.org)
Tactics and Techniques
Scattered Spider employs a range of tactics to infiltrate corporate networks. A hallmark of their strategy is social engineering, particularly voice phishing, or “vishing,” to manipulate help desk personnel into resetting employee passwords. This method has been notably effective, allowing the group to bypass multi-factor authentication (MFA) controls and gain unauthorized access to sensitive systems. (bitsight.com)

Once inside, the attackers focus on credential theft and network infiltration. They target privileged accounts, especially those of IT administrators and vendor support teams, to move laterally through the network, blending in as trusted users. This insider-like behavior makes detection challenging and positions them for maximum disruption and data theft. (coalitioninc.com)
High-Profile Attacks
Scattered Spider’s impact is evident in several high-profile cyberattacks. In September 2023, the group targeted MGM Resorts and Caesars Entertainment, two of the largest casino operators in the U.S. By impersonating internal IT support staff, they gained access to critical systems, leading to significant operational disruptions and financial losses.

In April 2025, Scattered Spider expanded its reach to the retail sector, executing coordinated attacks on several major UK retailers, including Marks & Spencer and the Co-op. These breaches resulted in the loss of sensitive customer data and prolonged disruptions to both in-store and digital services. Marks & Spencer reported an estimated £300 million in lost profits and a market value decline of £750 million following the attack. (ft.com)
Targeting the Insurance Industry
In June 2025, Scattered Spider shifted its focus to the U.S. insurance industry. Google’s Threat Intelligence Group reported multiple intrusions bearing all the hallmarks of Scattered Spider’s activity. Companies like Philadelphia Insurance Companies and Erie Insurance experienced significant disruptions due to unauthorized access and data exfiltration. (bleepingcomputer.com)
Collaboration with Ransomware-as-a-Service (RaaS) Operators
Scattered Spider often collaborates with RaaS operators, gaining access to specialized malware in exchange for a share of the ransom. For instance, during the attacks on UK retailers, the group deployed the DragonForce ransomware, leading to substantial operational disruptions and financial losses. (hackthebox.com)
Defending Against Scattered Spider
To defend against Scattered Spider’s tactics, organizations should implement robust identity verification protocols and replace outdated MFA methods, such as SMS and voice codes. Regular staff training on recognizing social engineering attempts is crucial, as is maintaining a comprehensive incident response plan. Additionally, monitoring for unusual user behavior and establishing detection mechanisms can help identify and mitigate potential breaches. (csoonline.com)
