FBI and CISA issue alert over escalating strategies employed by cyber threat group Scattered Spider
In the ever-evolving landscape of cybercrime, one collective stands out for its sophistication and expansion - Scattered Spider, also known as UNC3944. Active since late 2023, this group has targeted large companies across various sectors, including hospitality, telecommunications, retail, and more recently, Snowflake data storage solutions and financial services.
Scattered Spider's tactics are multi-faceted, combining phishing, SIM swapping, push bombing, ransomware deployment, and data extortion. They have been known to impersonate IT helpdesk and company employees, tricking victims into revealing credentials or MFA codes. They also employ adversary-in-the-middle techniques to intercept credentials and authentication factors.
One of their most notable tactics is push bombing, where repeated push MFA notifications are sent to users, aiming to pressure them into approval. SIM swap attacks are another method they use to take over mobile numbers, allowing them to intercept MFA codes and gain account access.
Once inside networks, Scattered Spider engages in data theft for extortion and has deployed various ransomware variants, including DragonForce, BlackCat (used in attacks on Caesars Entertainment and MGM Resorts), RansomHub, and Qilin. This diversification makes detection and prevention more challenging for defenders.
Recent collaborations and expansions to new sectors highlight the continued risk Scattered Spider poses to critical infrastructures and large enterprises worldwide. The group has been linked to incidents at Allianz Life Insurance Company of North America, affecting 1.4 million customers, and Qantas, where 5.7 million passengers' data was breached.
The FBI and CISA have released an updated advisory about Scattered Spider, with Canadian and Australian authorities also voicing concerns. Earlier this month, British authorities arrested four people in connection with social-engineering attacks that researchers have linked to Scattered Spider.
However, despite these arrests, Scattered Spider's campaigns continue with evolving tactics to evade detection. The suit filed by Clorox against its IT help-desk provider, Cognizant, alleges that the company handed over network credentials to the attackers without properly authenticating them.
Other groups, including UNC6040, have employed similar tactics to Scattered Spider, making it crucial for organizations to stay vigilant and implement robust security measures. Scattered Spider represents a serious and ongoing threat to U.S. organizations, emphasizing the need for continuous cybersecurity awareness and proactive defence strategies.
